(07/24/2014) Get ready to learn a new word: defaunation. Fauna is the total collection of animals—both in terms of species diversity and abundance—in a given area. So, defaunation, much like deforestation, means the loss of animals in all its myriad forms, including extinction, extirpation, or population declines.
Too much of a good thing: fertilizer 'one of the three major drivers of biodiversity loss this century'
(07/14/2014) The world’s grasslands are being destabilized by fertilization, according to a paper recently published in the journal Nature. In a study of 41 grassland communities on five continents, researchers found that the presence of fertilizer weakened grassland species diversity.
Next big idea in forest conservation? Playing games to understand what drives deforestation
(06/26/2014) Dr. Claude Garcia plays games, but you won’t find him betting his shirt at the casino. As leader of the Forest Management and Development Research Group at ETH Zürich, Garcia and his team use participatory modeling and role-playing games, merged with more traditional disciplinary sciences such as ecology, economics, and sociology to understand and manage complex landscape change in the tropics.
Next big idea in forest conservation? Making community protection economically viable
(05/29/2014) After years of discovering new species and setting up protected areas, Neil Burgesses' career changed. Currently he is focused on community-driven conservation and on how to improve protected areas in Africa's Eastern Arc mountains region. Neil Burgess has worked in the conservation field for over twenty years, mainly in Tanzania where he also lived for five years.
Next big idea in forest conservation? Linking public health and environmental degradation
(05/22/2014) Dr. Christopher Golden is an explorer on a mission. As both an epidemiologist and ecologist, he is investigating and expanding the interface between human and ecosystem health. This year, Golden was appointed the Director of Wildlife Conservation Society's HEAL (Health & Ecosystems: Analysis of Linkages) Program.
Seeing the Forest for the Trees: How 'One Health' Connects Humans, Animals, and Ecosystems
(05/05/2014) The emerging One Health movement recognizes the inextricable connections between human, animal, and ecosystem health and is leading not only to new scientific research but also to projects that help people rise out of poverty, improve their health, reduce conflicts with wildlife, and preserve ecosystems. Mongabay.org SRI Fellow Wendee Nicole reports.
Next big idea in forest conservation? Connecting deforestation to disease
(04/03/2014) Thomas Gillespie is concerned with the connections between conservation and disease, with a particular emphasis on primates. Much of his research examines the places where humans and animals are at a high risk of exchanging pathogens, and how human-caused disturbances, such as deforestation, can change disease dynamics and impacts.
Tree growth accelerates with age
(01/15/2014) Old, large trees may be even more important ecologically than long-believed, according to a new study in Nature. Looking at over half a million individual trees from over 400 species (both tropical and temperate), scientists have determined that most trees actually grow faster in their dotage than in their youth.
Over 75 percent of large predators declining
(01/09/2014) The world's top carnivores are in big trouble: this is the take-away message from a new review paper published today in Science. Looking at 31 large-bodied carnivore species (i.e those over 15 kilograms or 33 pounds), the researchers found that 77 percent are in decline and more than half have seen their historical ranges decline by over 50 percent. In fact, the major study comes just days after new research found that the genetically-unique West African lion is down to just 250 breeding adults.
Environmental degradation leads to public health crises
(01/07/2014) A 'systematic and comprehensive' approach is needed to understand the impact of human behavior on the world's public health, according to a new report. Written by the Heal (Health & Ecosystems Analysis of Linkages) consortium, the study highlights multiple examples of the impact on human health from environmental degradation, including sickness, death and even childhood reductions in IQ.
Scientists: well-managed forest restoration benefits both biodiversity and people
(12/16/2013) In November this year, the world was greeted by the dismaying news that deforestation of the Brazilian Amazon jumped 28% in the past year. The year 2013 also holds the dubious distinction of being the first time since humans appeared on the planet, that carbon concentrations in the atmosphere rose to 400 parts per million. A map by Google revealed that Russia, Brazil, the United States, Canada and Indonesia all displayed over 10 million hectares of gross forest loss from 2000-2012, with the highest deforestation rate occurring in Malaysia.
Deforestation may hurt U.S. agriculture, affect monsoon cycle
(11/04/2013) Unchecked deforestation will have far-reaching impacts on temperature, rainfall, and monsoon cycles in regions well outside the tropics, affecting agriculture and water availability, warns a new report published by Greenpeace International. The report is a synthesis of dozens of recent scientific papers that assess the effects of forest cover loss on weather patterns, local climate, and agricultural productivity.
Losing just one pollinator species leads to big plant declines
(07/22/2013) A shocking new study finds that losing just one pollinator species could lead to major declines in plant productivity, a finding that has broad implications for biodiversity conservation. Looking at ten bumblebee species in Colorado alpine meadows, two scientists found that removing a single bee species cut flower seed production by one-third. Pollinators worldwide are in major trouble as they are hit by habitat loss, pesticides, disease and other impacts. In fact, the EU has recently banned several pesticides that have been linked to the global bee decline.
Conserving top predators results in less CO2 in the air
(06/19/2013) What does a wolf in Yellowstone National Park have in common with an ambush spider on a meadow in Connecticut? Both are predators and thus eat herbivores, such as elk (in the case of wolves) and grasshoppers (in the case of spiders). Elk and grasshoppers also have more in common than you probably imagine: they both consume large quantities of plant matter. While scientists have long-known that predators lead to carbon storage by reducing herbivore populations, a new study reveals a novel way in which top predators cause an ecosystem to store more carbon.
How Business and Society Thrive by Investing in Nature - An interview with Mark Tercek
(05/15/2013) In 2008, The Nature Conservancy (TNC) surprised the conservation world when it selected Mark Tercek, an investment banker at Goldman Sachs, as its new president and CEO. For people familiar with Tercek, however, the move made perfect sense: he was a leading figure in Goldman's efforts to pursue new environmental policies. While at the helm of TNC, Mark Tercek has continued his focus on ecosystem services or attributing economic value to nature. In his new book, Nature’s Fortune, Mark discusses the fruit of this work.
Scientists discover that marine animals disperse seagrass
(05/09/2013) Lesser known than coral reefs, marine seagrass ecosystems are rich in biodiversity and are powerhouses when it comes to sequestering carbon dioxide. Yet, much remains unknown about the ecology of seagrass beds, including detailed information on how seagrass spread their seeds and colonize new area. Now a recent study in Marine Ecology Progress Series documents that several species of marine animal are key to dispersing seagrass, overturning the assumption that seagrass was largely dispersed by abiotic methods (such as wind and waves).
Europe bans pesticides linked to bee collapse
(04/29/2013) The EU has banned three neonicotinoid pesticides (imidacloprid, clothianidin and thiamethoxam) linked to the decline of bees for two years. The ban will apply to all flowering crops, such as corn, rape seed, and sunflowers. The move follows a flood of recent studies, some high-profile, that have linked neonicotinoid pesticides, which employ nicotine-like chemicals, to the widespread decline of bees seen both in Europe and North America.
What if companies actually had to compensate society for environmental destruction?
(04/29/2013) The environment is a public good. We all share and depend on clean water, a stable atmosphere, and abundant biodiversity for survival, not to mention health and societal well-being. But under our current global economy, industries can often destroy and pollute the environment—degrading public health and communities—without paying adequate compensation to the public good. Economists call this process "externalizing costs," i.e. the cost of environmental degradation in many cases is borne by society, instead of the companies that cause it. A new report from TEEB (The Economics of Ecosystems and Biodiversity), conducted by Trucost, highlights the scale of the problem: unpriced natural capital (i.e. that which is not taken into account by the global market) was worth $7.3 trillion in 2009, equal to 13 percent of that year's global economic output.
Greener neighborhoods have less violent crime
(04/04/2013) Turn your neighborhood green and it may prevent violent crime in the long run, according to a new study in Landscape and Urban Planning, which found that violent crimes (assaults, robberies, and burglaries) occurred less often in greener areas of Philadelphia. The connection between greener neighborhoods and less violent crime even stood up after researchers accounted for education, poverty, and population levels.
An insidious threat to tropical forests: over-hunting endangers tree species in Asia and Africa
(04/04/2013) A fruit falls to the floor in a rainforest. It waits. And waits. Inside the fruit is a seed, and like most seeds in tropical forests, this one needs an animal—a good-sized animal—to move it to a new place where it can germinate and grow. But it may be waiting in vain. Hunting and poaching has decimated many mammal and bird populations across the tropics, and according to two new studies the loss of these important seed-disperser are imperiling the very nature of rainforests.
Domesticated bees do not replace declining wild insects as agricultural pollinators
(04/03/2013) Sprinkled with pollen, buzzing bees fly from one blossom to another, collecting sweet nectar from brilliantly colored flowers. Bees tend to symbolize the pollination process, but there are many wild insects that carry out the same function. Unfortunately, wild insect populations are in decline, and, according to a recent study, adding more honey bees may not be a viable solution.
Seeing the forest through the elephants: slaughtered elephants taking rainforest trees with them
(03/11/2013) Elephants are vanishing. The booming illegal ivory trade is decimating the world's largest land animal, but no place has been harder hit than the Congo basin and its forest elephants (Loxodonta cyclotis). The numbers are staggering: a single park in Gabon, Minkebe National Park, has seen 11,100 forest elephants killed in the last eight years; Okapi Faunal Reserve in the Democratic Republic of the Congo has lost 75 percent of its elephants in fifteen years; and a new study in PLoS ONE estimates that in total 60 percent of the world's forest elephants have been killed in the last decade alone. But what does that mean for the Congo forest?
Warnings of global ecological tipping points may be overstated
(03/05/2013) There's little evidence that the Earth is nearing a global ecological tipping point, according to a new Trends in Ecology and Evolution paper that is bound to be controversial. The authors argue that despite numerous warnings that the Earth is headed toward an ecological tipping point due to environmental stressors, such as habitat loss or climate change, it's unlikely this will occur anytime soon—at least not on land. The paper comes with a number of caveats, including that a global tipping point could occur in marine ecosystems due to ocean acidification from burning fossil fuels. In addition, regional tipping points, such as the Arctic ice melt or the Amazon rainforest drying out, are still of great concern.
EU pushes ban on pesticides linked to bee downfall
(02/05/2013) Following a flood of damning research on the longterm impact of neonicotinoid pesticides on bee colonies, the EU is proposing a two year ban on the popular pesticides for crops that attract bees, such as corn, sunflower, oil seed rape, cotton. The proposal comes shortly after European Food Safety Authority (EFSA) released a report that found neonicotinoid pesticides posed a "number of risks" to bees.
Featured video: the miracle of mangroves
(01/30/2013) Mangroves are among the most important ecosystems in the world: they provide nurseries for fish, protect coastlines against dangerous tropical storms, mitigate marine erosion, store massive amounts of carbon, and harbor species found no-where else. However, they are vanishing at astonishing rates: experts say around 35 percent of the world's mangroves were lost in just twenty years (1990 to 2010).
Controversial research outlines physics behind how forests may bring rain
(01/30/2013) It took over two-and-a-half-years for the journal Atmospheric Chemistry and Physics to finally accept a paper outlining a new meteorological hypothesis in which condensation, not temperature, drives winds. If proven correct, the hypothesis could have massive ramifications on global policy—not to mention meteorology—as essentially the hypothesis means that the world's forest play a major role in driving precipitation from the coast into a continent's interior. The theory, known as the biotic pump, was first developed in 2006 by two Russian scientists, Victor Gorshkov and Anastassia Makarieva of the St. Petersburg Nuclear Physics, but the two have faced major pushback and delays in their attempt to put the theory before the greater scientific community.
Over $8 billion invested in watersheds in 2011
(01/28/2013) Unlike cars, hamburgers, and computers, clean drinking water is a requirement for human survival. In a bid to safeguard this essential resource, more and more nations are moving toward protecting ecosystems, such as forests, wetlands, and streams. In fact, according to a new report by Forest Trends' Ecosystem Marketplace, nations spent $8.17 billion in 2011 to secure freshwater by conserving watersheds.
Forests in Kenya worth much more intact says government report
(01/24/2013) Kenya's forests provide greater services and wealth to the nation when they are left standing. A landmark report by The Kenyan Government and the United Nations Environment Programme (UNEP) addresses the importance of forests to the well-being of the nation, putting Kenya among a pioneering group of countries that aim to center development plans around nature-based assets.
The Economics of Ecosystems and Biodiversity in Local and Regional Policy - a book review
(01/21/2013) The Economics of Ecosystems and Biodiversity in Local and Regional Policy, edited by Heidi Wittmar and Haripriya Gundimeda, provides thoughtful and actionable approaches to integrate nature’s benefits into decision-making frameworks for local and regional policy and public management institutions. Filled with numerous case studies, The Economics of Ecosystems and Biodiversity in Local and Regional Policy, delivers a compendium of concepts and ideas.
Scary caterpillar fungus could lead to new cancer drug
(01/14/2013) Cordyceps sinensis, commonly known as caterpillar fungus, may be a groundbreaking new treatment for a number of life-threatening conditions including asthma, kidney failure and cancer according to a paper recently published by The RNA Society. If you’re a caterpillar of the Tibetan Plateau, the fungus Cordyceps is your worst nightmare. It hits you when you’re most vulnerable, during hibernation. You can try to stay awake, but on the Tibetan plateau, which reaches −40 degrees Celsius during the winter, you’ll have to hibernate sooner or later, and the fungus will be waiting for you.
World has lost half its wetlands
(11/29/2012) Half of the worlds wetlands have been destroyed in just the last 100 years, says a new report. Published by the Economics of Ecosystems and Biodiversity (TEEB), the report found that of the 25 million square kilometers of wetlands that existed in 1900 just 12.8 million square kilometers now remain. The rate of destruction varies geographically with notable loses in East Asia running at 1.6 per cent per year. In places where aquaculture, over-exploitation (e.g. unsustainable harvesting of fish) and storm damage have been severe, the rate of destruction can be as high as 80 percent.
Investors shouldn't ignore financial risk of environmental damage
(11/29/2012) Environmental damage poses a long-ignored risk to sovereign bonds, according to a new report by the UNEP FI (The United Nations Environment Programme Finance Initiative) and the Global Footprint Network. The report, E-RISC Report, A New Angle on Sovereign Credit Risk, finds that the overuse of natural resources and their degradation has put considerable, and largely unrecognized, risk against national economies.
Legislation leaves future of world's largest temperate rainforest up in the air
(11/27/2012) Although unlikely to pass anytime in the near term, recurring legislation that would hand over 80,000 acres of the Tongass Rainforest to a Native-owned logging corporation has put local communities on guard in Southeast Alaska. "The legislation privatizes a public resource. It takes land that belongs to all of us, and that all of us have a say in the use and management of, and it gives that land to a private for-profit corporation," Andrew Thoms, Executive Director of the Sitka Conservation Society, told mongabay.com in a recent interview.
Wolves, mole rats, and nyala: the struggle to conserve Ethiopia's highlands
(11/20/2012) There is a place in the world where wolves live almost entirely off mountain rodents, lions dwell in forests, and freshwater rolls downstream to 12 million people, but the place—Ethiopia's Bale Mountains National Park—remains imperiled by a lack of legal boundaries and encroachment by a growing human population. "Much of the land in Africa above 3,000 meters has been altered or degraded to the point where it isn’t able to perform most of the ecosystem functions that it is designed to do. Bale, although under threat and already impacted to a degree by anthropogenic activities, is still able to perform its most important ecosystem functions, and as such ranks among only a handful of representative alpine ecosystems in Africa."
Future of the Tongass forest lies in salmon, not clear-cut logging
(10/25/2012) The Parnell administration's Timber Task Force recently unveiled a proposal to carve out two million acres of the Tongass National Forest for clear-cut logging under a state-managed "logging trust." The stated goal is to revive Southeast Alaska’s timber industry that collapsed two decades ago amid changing market conditions, logging cutbacks and evolving public opinion about timber harvesting on national forests.
India pledges over $60 million for biodiversity, but experts say much more needed
(10/18/2012) The Prime Minister of India, Manmohan Singh, pledged around $50 million (Rs. 264 crore) for domestic biodiversity protection, reports the Hindu. The pledge came this week at the Convention on Biological Diversity (CBD) meeting in Hyderabad, India. The CBD has set bold goals on stemming the rate of extinction worldwide, but these have suffered from a lack of funding. India also said it had set aside another $10 million (Rs. 50 crore) for biodiversity projects abroad. Still, such funds are far below what scientists say is necessary to stem ongoing extinctions.
Saving the world's species from oblivion will cost around $80 billion a year, but still a good deal
(10/11/2012) If the world is to conserve its wealth of life—species great and small, beautiful and terrible, beloved and unknown—it will cost from $3.41-4.76 billion annually in targeted conservation funds, according to a new study in Science. But that's not all, the cost of protecting and managing the world's conservation areas was estimated at an additional $76.1 billion a year.
Forest destruction leads to more floods in temperate regions
(10/04/2012) Keeping forests standing would lessen both the number and size of spring floods in temperate regions, according to a new study in Water Resources Research, by slowing seasonal snow melts. In deforested areas, snow melts faster due to a lack of shade causing at least twice as many, and potentially up to four times as many, flood events. The new research highlights a largely unknown ecosystem service provided by temperate forests: flood mitigation.
Learning to live with elephants in Malaysia
(09/18/2012) Humans and elephants have a lot in common: both are highly intelligent, intensely social, and both are capable of having a massive impact on their local environments. Given their similarities, it might not be surprising that elephants and human have often run afoul of one another. Conflict between these two great species has probably been going on for thousands of years, but as human populations have grown dramatically, elephant populations have been crippled and forced into smaller-and-smaller pockets. No-where is this more true than in Southeast Asia.
Arachnopocalypse: with birds away, the spiders play in Guam
(09/17/2012) The island of Guam is drowning in spiders. New research in the open-access journal PLOS ONE has found that in the wet season, Guam's arachnid population booms to around 40 times higher than adjacent islands. Scientists say this is because Guam, a U.S. territory in the Pacific, has lost its insect-eating forest birds. Guam's forests were once rich in birdlife until the invasion of non-native brown tree snake (Boiga irregularis) in the 1940s decimated biodiverse bird communities. Now, the island is not only overrun with snakes, but spiders too.
Bird diversity at risk if 'agroforests' replaced with farmland
(09/13/2012) Agroforests contain much higher levels of bird diversity than their open agricultural counterparts, according to new research from the University of Utah. If large forests and agroforests continue to be replaced by simple open farms, bird communities will become much less specialized and entire groups may become extinct. Important roles for birds, such as pollination, pest control or seed dispersal, may remain unfilled if ongoing trends toward open agriculture continues and biodiversity decreases.
Mangroves protect coastal areas against storm damage
(09/07/2012) Mangroves reduce wave height by as much as 66 percent over 100 meters of forest providing a vital buffer against the impacts of storms, tsunamis, and hurricanes, according to a new report published by The Nature Conservancy and Wetlands International.
Amazon deforestation could trigger drop in rainfall across South America
(09/06/2012) Deforestation could cause rainfall across the Amazon rainforest to drop precipitously, warns a new study published in the journal Nature. Using a computer model that accounts for forest cover and rainfall patterns, Dominick Spracklen of the University of Leeds and colleagues estimate that large-scale deforestation in the Amazon could reduce basin-wide rainfall 12 percent during the wet season and 21 percent in the dry season by 2050. Localized swings would be greater.
Rainforest fungi, plants fuel rainfall
(09/04/2012) Salt compounds released by fungi and plants in the Amazon rainforest have an important role in the formation of rain clouds, reports research published in the journal Science.
Private reserve safeguards newly discovered frogs in Ecuadorian cloud forest
(08/28/2012) Although it covers only 430 hectares (1,063 acres) of the little-known Chocó forest in Ecuador, the private reserve las Gralarias in Ecuador is home to an incredible explosion of life. Long known as a birder's paradise, the Reserva las Gralarias is now making a name for itself as a hotspot for new and endangered amphibians, as well as hundreds of stunning species of butterfly and moth. This is because the reserve is set in the perfect place for evolution to run wild: cloud forest spanning vast elevational shifts. "The pacific slope cloud forests [...] are among the most endangered habitats in the world," explains Reserva las Gralarias' founder, Jane Lyons, in a recent interview with mongabay.com.
Human society surpasses 'nature's budget' today
(08/22/2012) As of today, August 22nd, humanity has overshot the world's annual ecological budget, according to the Global Footprint Network, which tracks global consumption related to resource availability and sustainability. The organization looks at a variety of data including the world's fisheries, forests, agriculture, water, mining, and greenhouse gas emissions.
Mangroves should be part of solution to climate change
(08/02/2012) Mangroves are under-appreciated assets in the effort to slow climate change, argues a new Proceedings of the National Academy of Sciences paper which makes a argument for including the coastal ecosystems in carbon credit programs.
Guyana rainforests secure trust fund
(07/30/2012) The nation of Guyana sports some of South America's most intact and least-imperiled rainforests, and a new $8.5 million trust fund hopes to keep it that way. The Guyanese government has teamed up with Germany and Conservation International (CI) to create a long-term trust fund to manage the country's protected areas system (PAS).
Saving 'Avatar Grove': the battle to preserve old-growth forests in British Columbia
(07/23/2012) A picture is worth a thousand words: this common adage comes instantly to mind when viewing T.J. Watt's unforgettable photos of lost trees. For years, Watt has been photographing the beauty of Vancouver Island's ancient temperate rainforests, and documenting their loss to clearcut logging. The photographer and environmental activist recently helped co-found the Ancient Forest Alliance (AFA), a group devoted to saving the island's and British Columbia's (BC) last old-growth while working with the logging industry to adopt sustainable practices. This February the organization succeeded in saving Avatar Grove—which was only discovered in 2009—from being clearcut. The grove, a rare stand of massive and ancient trees named after the popular eco science-fiction movie, has become a popular tourist destination, providing a new economic incentive for communities to protect rather than cut Canada's last great forests.
2,600 scientists: climate change killing the world's coral reefs
(07/10/2012) In an unprecedented show of concern, 2,600 (and rising) of the world's top marine scientists have released a Consensus Statement on Climate Change and Coral Reefs that raises alarm bells about the state of the world's reefs as they are pummeled by rising temperatures and ocean acidification, both caused by greenhouse gas emissions. The statement was released at the 12th International Coral Reef Symposium.
Congolese experts needed to protect Congo Basin rainforests
(06/20/2012) This summer, the Democratic Republic of Congo (DRC) is expected to approve a new higher education strategy which the country has developed with the World Bank and other international donors. The shape of this educational reform initiative will be critical to Congo's future in many ways. It could finally offer Congo’s long-suffering people a route into the 21st century. It will also help determine the future of the DRC’s forests. Nearly half of the Congo Basin’s remaining rainforest is in the DRC—yet the critical role of Congolese experts in forestry, agricultural science, wildlife management and other rural sciences in protecting this forest is not widely recognized.
Rio+20 and economic perils in Europe: opportunity for linkage
(06/19/2012) This month, momentous events will occur on the global scene that will set the tone for whether 2012 will be a hopeful year or one in which dislocations and disconnects are further exacerbated by political failings. The EU will decide on its fiscal and monetary union that hinges on Greece’s recent June election, which backed the political party that wants to stay in the Euro zone, but insists on adjustments to the earlier-negotiated economic rescue package.
Should we devote 2014 to wilderness?
(06/11/2012) American writer and philosopher, Henry David Thoreau once said, "In wilderness is the preservation of the world." Anyone who has spent time in vast untouched wild space likely understands Thoreau's comment. Yet wilderness everywhere—already vanishing—remains imperiled by a variety of threats. To draw attention to the importance of the keeping wilderness in the world, PAN Parks, an organization that works to protect wilderness in Europe, has proposed to make 2014 the International Year of Wilderness.
Forgotten Species: the wonder-inducing giant clam
(06/11/2012) The first time I ever saw a giant clam was at a ride in Walt Disney World's Magic Kingdom. My family and I piled into the Nautilus submersible at the 20,000 Leagues Under the Sea: Submarine Voyage and descended into the playtime depths. While we saw sea turtles, sharks, lobsters, mermaids, and even a sea monster, the creature that lingered in my mind most was the giant clam, raising and closing its pearly shell in the weedy abyss. Of course, none of these aquatic wonders were real—they were animatronics—but to a child with a vivid imagination they stirred within me the deep mystery of the boundless ocean, and none more so than that monstrous clam with its gaping maw.
Ten African nations pledge to transform their economies to take nature into account
(06/11/2012) Last month ten African nations, led by Botswana, pledged to incorporate "natural capital" into their economies. Natural capital, which seeks to measure the economic worth of the services provided by ecosystems and biodiversity—for example pollination, clean water, and carbon—is a nascent, but growing, method to curtail environmental damage and ensure more sustainable development. Dubbed the Gaborone Declaration, the pledge was signed by Botswana, Liberia, Namibia, Mozambique, Rwanda, Gabon, Ghana, Kenya, South Africa, and Tanzania following a two day summit.
Scientists: if we don't act now we're screwed
(06/07/2012) Scientists warn that the Earth may be reaching a planetary tipping point due to a unsustainable human pressures, while the UN releases a new report that finds global society has made significant progress on only four environmental issues out of ninety in the last twenty years. Climate change, overpopulation, overconsumption, and ecosystem destruction could lead to a tipping point that causes planetary collapse, according to a new paper in Nature by 22 scientists. The collapse may lead to a new planetary state that scientists say will be far harsher for human well-being, let alone survival.
Scientists to Rio+20: save biodiversity to save ourselves
(06/06/2012) World leaders need to do much more to protect the Earth's millions of species for the services they provide, according to a new scientific consensus statement in Nature based on over 1,000 research papers. Written by 17 top ecologists, the statement points out that despite growing knowledge of the importance of biodiversity for human well-being and survival, species continue to vanish at alarming rates. The statement comes just weeks before the UN'S Rio+20 Summit on Sustainable Development, which is supposed to chart a path for a less impoverished and more equitable world including an emphasis on greater environmental protections, but which has been marred by a lack of ambition.
Highest priority conservation sites provide essential services for people too
(06/05/2012) Preventing the extinction of the world's most imperiled species would also bring untold benefits to people according to new research in the open-access journal PLoS ONE. Looking at the world's nearly 600 Alliance for Zero Extinction (AZE) sites, the study found that preserving these ecosystems would benefit humans even beyond preserving biodiversity, including safeguarding freshwater, carbon storage, and protecting cultural diversity. AZE sites are identified as habitats containing one or more species listed as Endangered or Critically Endangered by the IUCN Red List, in which the survival of the species is highly dependent on the conservation of the ecosystem in question.
Seagrass beds store 20 billion tons of carbon
(05/22/2012) Just below the ocean's surface lies a carbon powerhouse: seagrass meadows. New research in Nature Geoscience estimates that the world's seagrass meadows conservatively store 19.9 billion metric tons of carbon, even though the threatened marine ecosystems make up only 0.2 percent of Earth's surface. The findings lend support to the idea that seagrass protection and restoration could play a major role in mitigating climate change.
Consumption, population, and declining Earth: wake-up call for Rio+20
(05/15/2012) Currently, human society is consuming natural resources as if there were one-and-a-half Earths, and not just a single blue planet, according to the most recent Living Planet Report released today. If governments and societies continue with 'business-as-usual' practices, we could be consuming three years of natural resources in 12 months by 2050. Already, this ecological debt is decimating wildlife populations worldwide, disproportionately hurting the world's poor and most vulnerable, threatening imperative resources like food and water, heating up the atmosphere, and risking global well-being.
Wildlife in the tropics plummets by over 60 percent
(05/15/2012) In 48 years wildlife populations in the tropics, the region that holds the bulk of the world's biodiversity, have fallen by an alarming 61 percent, according to the most recent update to the Living Planet Index. Produced by the World Wide Fund for Nature (WWF) and the Zoological Society of London (ZSL), the index currently tracks almost 10,000 populations of 2,688 vertebrate species (including mammals, birds, reptiles, amphibians, and fish) in both the tropics and temperate regions.
Biodiversity loss cripples plant growth
(05/02/2012) For decades scientists have been warning that if global society continues with "business-as-usual" practices the result will be a mass extinction of the world's species, an extinction event some researchers say is already underway. However, the direct impacts of global biodiversity loss has been more difficult to compile. Now a new study in Nature finds that loss of plant biodiversity could cripple overall plant growth.
Doing good and staying sane amidst the global environmental crisis
(04/23/2012) Several years ago while teaching a course in environmental science a student raised her hand during our discussion of the circumstances of modern ecological collapse and posed the question, "what happens when there is no more environment?" At the time I had no response and stumbled to formulate some sort of reply based on the typical aseptic, apathetic logic with which we are programmed through education in the scientific tradition: that there will always be some sort of environment, that life has prospered through the five previous mass extinctions and that something will survive. While this may be the case, the time has come for more of us to consider the broader spectrum of what global humanity is facing as the planet’s ecology is decimated.

(04/22/2012) The past ten years have seen unprecedented progress in fighting deforestation in the Amazon. Indigenous rights, payments for ecosystem services, government enforcement, satellite imagery, and a spirit of cooperation amongst old foes has resulted in a decline of 80 percent in Brazil's deforestation rates.
For Earth Day, 17 celebrated scientists on how to make a better world
(04/22/2012) Seventeen top scientists and four acclaimed conservation organizations have called for radical action to create a better world for this and future generations. Compiled by 21 past winners of the prestigious Blue Planet Prize, a new paper recommends solutions for some of the world's most pressing problems including climate change, poverty, and mass extinction. The paper, entitled Environment and Development Challenges: The Imperative to Act, was recently presented at the UN Environment Program governing council meeting in Nairobi, Kenya.
U.S. gobbling illegal wood from Peru's Amazon rainforest
(04/10/2012) The next time you buy wood, you may want to make sure it's not from Peru. According to an in-depth new report by the Environmental Investigation Agency (EIA), the illegal logging trade is booming in the Peruvian Amazon and much of the wood is being exported to the U.S. Following the labyrinthian trail of illegal logging from the devastated forests of the Peruvian Amazon to the warehouses of the U.S., the EIA identified over 112 shipments of illegally logged cedar and big-leaf mahogany between January 2008 and May 2010. In fact, the group found that over a third (35 percent) of all the shipments of cedar and mahogany from Peru to the U.S. were from illegal sources, a percentage that is likely conservative.
Smoking gun for bee collapse? popular pesticides
(03/29/2012) Commonly used pesticides may be a primary driver of the collapsing bee populations, finds two new studies in Science. The studies, one focused on honeybees and the other on bumblebees, found that even small doses of these pesticides, which target insect's central nervous system, impact bee behavior and, ultimately, their survival. The studies may have far-reaching repercussions for the regulation of agricultural chemicals, known as neonicotinoid insecticides, that have been in use since the 1990s.
Over 5,000 vital biodiversity sites remain unprotected
(03/22/2012) A recent study has found that half of the world's Important Bird Areas (IBAs) and Alliance for Zero Extinction (AZE) sites remain unprotected, leaving many endangered species, some on the verge of extinction, gravely vulnerable to habitat loss. Published in the open access journal PLoS ONE, the study urges governments to focus on expanding protected areas to cover the species that need it most.
Amazon plant yields miracle cure for dental pain
(03/14/2012) The world may soon benefit from a plant long-used by indigenous people in the Peruvian Amazon for toothaches, eliminating the need for local injections in some cases. Researchers have created a medicinal gel from a plant known commonly as spilanthes extract (Acmella Oleracea), which could become a fully natural alternative to current anesthetics and may even have a wide-range of applications beyond dental care.
Alaskan fishermen tell government to focus on salmon, not logging
(03/12/2012) Alaskan fishermen and tour operators visited Washington D.C. last week to urge the federal government to shift the focus from logging to conservation in the Tongass rainforest. Local Alaskans along with NGOs Trout Unlimited, Alaska Program, and Sitka Conservation Society, made the case that conservation, including the restoration of fish habitat, was a far better strategy for the local economy and jobs than logging. The Tongass rainforest is currently the subject of a controversial logging proposal by the government for the indigenous-owned company, Sealaska.
California cap-and-trade law spurs U.S. forest carbon projects
(02/15/2012) Now that California's carbon market has arrived, an Australian-based company that specializes in forest carbon offsets has jump started two forest projects with private landowners in the western U.S. The new company, Forest Carbon Partners, will make the projects available as carbon offsets for California polluters.
Majority of protected tropical forests "empty" due to hunting
(02/08/2012) Protected areas in the world's tropical rainforests are absolutely essential, but one cannot simply set up a new refuge and believe the work is done, according to a new paper in Bioscience. Unsustainable hunting and poaching is decimating tropical forest species in the Amazon, the Congo, Southeast Asia, and Oceana, leaving behind "empty forests," places largely devoid of any mammal, bird, or reptile over a few pounds. The loss of such species impacts the whole ecosystems, as plants lose seed dispersers and the food chain is unraveled.
More big companies disclosing impacts on forests
(02/07/2012) More companies are reporting on the impact of their operations on global forests, finds a new report. Eighty-seven global corporations disclosed their "forest footprint" in 2011, according to the third Forest Footprint Disclosure (FFD), which asks companies to report on their impact on forests based on their use of five commodities: soy, palm oil, timber and pulp, cattle, and biofuels. This is a 11 percent rise from the companies that reported in 2010, including the first reports by companies such as the Walt Disney Company, Tesco UK, and Johnson & Johnson. However a number of so-called "green" companies continue to refuse to disclose, including Patagonia, Stonyfield Farms, and Whole Foods Markets Inc.
New meteorological theory argues that the world's forests are rainmakers
(02/01/2012) New, radical theories in science often take time to be accepted, especially those that directly challenge longstanding ideas, contemporary policy or cultural norms. The fact that the Earth revolves around the sun, and not vice-versa, took centuries to gain widespread scientific and public acceptance. While Darwin's theory of evolution was quickly grasped by biologists, portions of the public today, especially in places like the U.S., still disbelieve. Currently, the near total consensus by climatologists that human activities are warming the Earth continues to be challenged by outsiders. Whether or not the biotic pump theory will one day fall into this grouping remains to be seen. First published in 2007 by two Russian physicists, Victor Gorshkov and Anastassia Makarieva, the still little-known biotic pump theory postulates that forests are the driving force behind precipitation over land masses.
Protecting original wetlands far preferable to restoration
(01/26/2012) Even after 100 years have passed a restored wetland may not reach the state of its former glory. A new study in the open access journal PLoS Biology finds that restored wetlands may take centuries to recover the biodiversity and carbon sequestration of original wetlands, if they ever do. The study questions laws, such as in the U.S., which allow the destruction of an original wetland so long as a similar wetland is restored elsewhere.
Economic slowdown leads to the pulping of Latvia's forests
(01/23/2012) The economic crisis has pushed many nations to scramble for revenue and jobs in tight times, and the small Eastern European nation of Latvia is no different. Facing tough circumstances, the country turned to its most important and abundant natural resource: forests. The Latvian government accepted a new plan for the nation's forests, which has resulted in logging at rates many scientists say are clearly unsustainable. In addition, researchers contend that the on-the-ground practices of state-owned timber giant, Latvijas Valsts meži (LVM), are hurting wildlife and destroying rare ecosystems.
Recognizing value of nature could boost income for the world's poor
(01/20/2012) The rural poor would substantially boost their income if the ecological services of the ecosystems they steward were valued and compensated by the rest of the world, claims a new study published in the journal Bioscience.
Disease kills 6 million bats in North America
(01/18/2012) In just six years around six million bats have succumbed to white-nose syndrome in North America, according to U.S. federal researchers. The number, somewhere between 5.7 and 6.7 million bats, is far higher than past estimates of over a million. Showing up in 2006 in New York, the perplexing disease, which appears as white dust on bats' muzzles, wipes out populations while they hibernate.
How lemurs fight climate change
(01/09/2012) Kara Moses may have never become a biologist if not for a coin toss. The coin, which came up heads and decided Moses' direction in college, has led her on a sinuous path from studying lemurs in captivity to environmental writing, and back to lemurs, only this time tracking them in their natural habitat. Her recent research on ruffed lemurs is attracting attention for documenting the seed dispersal capabilities of Critically Endangered ruffed lemurs as well as theorizing connections between Madagascar's lemurs and the carbon storage capacity of its forests. Focusing on the black-and-white ruffed lemur's (Varecia variegata) ecological role as a seed disperser—animals that play a major role in spreading a plant's seeds far-and-wide—Moses suggests that not only do the lemurs disperse key tree species, but they could be instrumental in dispersing big species that store large amounts of carbon.
Is the Russian Forest Code a warning for Brazil?
(12/19/2011) Brazil, which last week moved to reform its Forest Code, may find lessons in Russia's revision of its forest law in 2007, say a pair of Russian scientists. The Brazilian Senate last week passed a bill that would relax some of forest provisions imposed on landowners. Environmentalists blasted the move, arguing that the new Forest Code — provided it is not vetoed by Brazilian President Dilma Rousseff next year — could undermine the country's progress in reducing deforestation.
Locals key to saving primate-rich wetlands in Cote D'Ivoire
(12/12/2011) Saved from being converted into a vast palm oil plantation by PALM-CI in 2009, the Ehy Tanoé wetlands and forest in the Cote D'Ivoire (Ivory Coast) is home to three gravely endangered primates and as well as many other species. Since 2006, a pilot community management program has been working to protect the 12,000 hectare area, and a new study in mongabay.com's open access journal Tropical Conservation Science finds that long-term conservation of the Ehy Tanoé wetlands and forest is, in fact, vital for locals who depend on the area for hunting, fishing, firewood, building materials, and medicinal plants. In addition, the study finds that the ecosystem has special cultural and spiritual importance to locals.
Evidence mounts that Maya did themselves in through deforestation
(12/08/2011) Researchers have garnered further evidence for a smoking gun behind the fall of the great Maya civilization: deforestation. At the American Geophysical Union (AGU) conference, climatologist Ben Cook presented recent research showing how the destruction of rainforests by the Mayan ultimately led to declines in precipitation and possibly civilization-rocking droughts. While the idea that the Maya may have committed ecological-suicide through deforestation has been widely discussed, including in Jared Diamond's popular book Collapse, Cook's findings add greater weight to the theory.
Agriculture group to spend 10 years on forest research
(12/07/2011) Recognizing the global importance of the world's vanishing forests, a 10-year-long research program will focus on the interconnection between agriculture and forests. Conducted by CGIAR, a global agriculture group concerned with sustainability, the research program will look at ways to decrease forest loss and degradation.
Giant rat plays big ecological role in dispersing seeds
(11/16/2011) Rats are rarely thought of as heroes. In fact, in many parts of the world they are despised, while in others they serve largely as food. But, scientists are now discovering that many tropical forest rodents, including rats, serve as heroic seed dispersers, i.e. eating fruits and nuts, and carrying seeds far from the parent tree, giving a chance to a new sapling. While this has been documented with tropical rodents in South America like agoutis and acouchis, a new study in Biotropica documents the first successful seed dispersal by an African rodent: the Kivu giant pouched rat (Cricetomys kivuensis), one of four species of giant African rats.
Critically Endangered lemurs disperse seeds, store carbon
(11/13/2011) Many tropical plants depend on other species to carry their progeny far-and-wide. Scientists are just beginning to unravel this phenomenon, known as seed dispersal, which is instrumental in supporting the diversity and richness of tropical forests. Researchers have identified a number of animal seed dispersers including birds, rodents, monkeys, elephants, and even fish. Now a new study in the Journal of Tropical Ecology adds another seed disperser to that list: the Critically Endangered black-and-white ruffed lemur (Varecia variegata). Capable of dispersing big tree species, the black-and-white ruffed lemur may even play a big role in carbon sequestration.
Unsung heroes: the life of a wildlife ranger in the Congo
(11/01/2011) The effort to save wildlife from destruction worldwide has many heroes. Some receive accolades for their work, but others live in obscurity, doing good—sometimes even dangerous—work everyday with little recognition. These are not scientists or big-name conservationists, but wildlife rangers, NGO staff members, and low level officials. One of these conservation heroes is Bunda Bokitsi, chief guard of the Etate Patrol Post for Salonga National Park in the Democratic Republic of the Congo. In a nation known for a prolonged civil war, desperate poverty, and corruption—as well as an astounding natural heritage—Bunda Bokitsi works everyday to secure Salonga National Park from poachers, bushmeat hunters, and trappers.
Featured video: could a forest be worth more than a gold mine?
(10/31/2011) Jason A. Sohigian, the Deputy Director of the Armenia Tree Project (ATP), presents at TEDx on the often-unacknowledged economic value of forests, including wildlife habitat, safeguarding watersheds, soil health, and tourism. In Amerina, Sohigian estimates the economic value of forests to be between $7 million to $1.1 billion annually, if not more.
11 challenges facing 7 billion super-consumers
(10/31/2011) Perhaps the most disconcerting thing about Halloween this year is not the ghouls and goblins taking to the streets, but a baby born somewhere in the world. It's not the baby's or the parent's fault, of course, but this child will become a part of an artificial, but still important, milestone: according to the UN, the Earth's seventh billionth person will be born today. That's seven billion people who require, in the very least, freshwater, food, shelter, medicine, and education. In some parts of the world, they will also have a car, an iPod, a suburban house and yard, pets, computers, a lawn-mower, a microwave, and perhaps a swimming pool. Though rarely addressed directly in policy (and more often than not avoided in polite conversations), the issue of overpopulation is central to environmentally sustainability and human welfare.
Five ways to feed billions without trashing the planet
(10/13/2011) At the end of this month the UN predicts global population will hit 7 billion people, having doubled from 3.5 billion in less than 50 years. Yet even as the Earth hits this new milestone, one billion people do not have enough food; meanwhile the rapid expansion of agriculture is one of the leading causes of global environmental degradation, including greenhouse gas emissions, destruction of forests, marine pollution, mass extinction, water scarcity, and soil degradation. So, how do we feed the human population—which continues to rise and is expected to hit nine billion by 2050—while preserving the multitude of ecosystem services that support global food production? A new study in Nature proposes a five-point plan to this dilemma.
Putting people to work: restoring our ecosystems, sequestering carbon
(10/02/2011) President Obama's sole focus of his September 8th speech to the United States Congress was job creation. He closed his speech by summoning an earlier time of promise: "President Kennedy once said, ' Our problems are man-made—therefore they can be solved by man. And man can be as big as he wants.' These are difficult years for our country. But we are Americans. We are tougher than the times we live in, and we are bigger than our politics have been. So let's meet the moment. Let's get to work..." Inspiration is surely needed because in addition to the United States, where unemployment remains at about 9 percent, severe unemployment is found throughout the world, with Greece, Spain, and South Africa, for example, having 2011 summer unemployment rates at over 16, 20, and 25 percent, respectively.
Forest carbon projects rake in $178 million in 2010
(09/29/2011) Investors funneled $178 million into forest carbon projects intended to mitigate global climate change last year, according to a new report by Forest Trends' Ecosystem Marketplace. By trading a record 30.1 million tons of carbon dioxide equivalent (MtC02e), the market saw a 48 percent rise over 2009—including a rise in private investors over non-profits as well as greater support for the global program Reduced Emissions from Deforestation and forest Degradation (REDD)—shows that the burgeoning market may be beginning to make good on its promise to provide funds to save forests for their ecosystem services with an initial focus on carbon.
Atlantic Forest stores less carbon due to drastic fragmentation
(09/26/2011) The Atlantic Forest in Brazil is one of the most fragmented and damaged forests in the world. Currently around 12 percent of the forest survives, with much of it in small fragments, many less than 100 hectares. A new study in mongabay.com's open-access journal Tropical Conservation Science finds that the bloodied nature of the Atlantic Forest impacts its capacity to sequester carbon. The study found that 92 percent of the forest stored only half its potential carbon due to fragmentation and edge-effects, which includes damage due to winds and exposure to drought.
Panama canal drives forest conservation, offers insight on value of ecosystems
(09/26/2011) As demonstrated by growing enthusiasm for conserving forests and the rise of the Reducing Emissions from Deforestation and Degradation (REDD+) program, the public is increasingly aware of the role forests play in delivering ecosystems services — like clean air and water — that benefit mankind. Yet, science still lags conventional wisdom — researchers have yet to fully quantify much of what healthy forests provide. Bridging this gap is key to unlocking the full value of protecting and restoring tropical forests. The ambitious Agua Salud Project in Panama is attempting to do just that.
China's new forests aren't necessarily green
(09/21/2011) When most of Asia is cutting down its forests, China stands apart. In the last two decade the massive country has gained over 30 percent forest cover. However, a new opinion piece by Jianchu Xu, with the World Agroforestry Centre and the Kunming Institute of Botany, argues that China's growing forest is not what it appears to be. The problem, according to Xu, is that the statistics of forest cover include monoculture plantations.
Sowing the seeds to save the Patagonian Sea
(09/07/2011) With wild waters and shores, the Patagonia Sea is home to a great menagerie of marine animals: from penguins to elephants seals, albatrosses to squid, and sea lions to southern right whales. The sea lies at crossroads between more northern latitudes and the cold bitter water of the Southern Ocean, which surround Antarctica. However the region is also a heavy fishing ground, putting pressure on a number of species and imperiling the very ecosystem that supplies the industry. Conservation efforts, spearheaded by marine conservationist Claudio Campagna and colleagues with the Wildlife Conservation Society (WCS), are in the early stages. Campagna, who often writes about the importance of language in the fight for preservation, has pushed to rename the area to focus on its stunning wildlife.
Controversial study finds intensive farming partnered with strict protected areas is best for biodiversity
(09/01/2011) Given that we have very likely entered an age of mass extinction—and human population continues to rise (not unrelated)—researchers are scrambling to determine the best methods to save the world's suffering species. In the midst of this debate, a new study in Science, which is bound to have detractors, has found that setting aside land for strict protection coupled with intensive farming is the best way to both preserve species and feed a growing human world. However, other researchers say the study is missing the point, both on global hunger and biodiversity.
World on the Edge: How to Prevent Environmental and Economic Collapse
(08/30/2011) World on the Edge: How to Prevent Environmental and Economic Collapse clearly describes in terms of national and social security how the looming current threat to our collective global future is not from catastrophic war as many describe in hindsight the 20th Century, rather from cataclysmic climate change, biodiversity loss, and water degradation.
Cameratraps take global snapshot of declining tropical mammals
(08/17/2011) A groundbreaking cameratrap study has mapped the abundance, or lack thereof, of tropical mammal populations across seven countries in some of the world's most important rainforests. Undertaken by The Tropical Ecology Assessment and Monitoring Network (TEAM), the study found that habitat loss was having a critical impact on mammals. The study, which documented 105 mammals (nearly 2 percent of the world's known mammals) on three continents, also confirmed that mammals fared far better—both in diversity and abundance—in areas with continuous forest versus areas that had been degraded.
Lessons from the world's longest study of rainforest fragments
(08/15/2011) For over 30 years, hundreds of scientists have scoured eleven forest fragments in the Amazon seeking answers to big questions: how do forest fragments' species and microclimate differ from their intact relatives? Will rainforest fragments provide a safe haven for imperiled species or are they last stand for the living dead? Should conservation focus on saving forest fragments or is it more important to focus the fight on big tropical landscapes? Are forest fragments capable of regrowth and expansion? Can a forest—once cut-off—heal itself? Such questions are increasingly important as forest fragments—patches of forest that are separated from larger forest landscapes due to expanding agriculture, pasture, or fire—increase worldwide along with the human footprint.
Balancing agriculture and rainforest biodiversity in India’s Western Ghats
(08/08/2011) When one thinks of the world's great rainforests the Amazon, Congo, and the tropical forests of Southeast Asia and Indonesia usually come to mind. Rarely does India—home to over a billion people—make an appearance. But along India’s west coast lies one of the world's great tropical forests and biodiversity hotspots, the Western Ghats. However it's not just the explosion of life one finds in the Western Ghats that make it notable, it's also the forest's long—and ongoing—relationship to humans, lots of humans. Unlike many of the world's other great rainforests, the Western Ghats has long been a region of agriculture. This is one place in the world where elephants walk through tea fields and tigers migrate across betel nut plantations. While wildlife has survived alongside humans for centuries in the region, continuing development, population growth and intensification of agriculture are putting increased pressure on this always-precarious relationship. In a recent paper in Biological Conservation, four researchers examine how well agricultural landscapes support biodiversity conservation in one of India's most species-rich landscapes.
