(12/12/2011) Long eaten by indigenous populations, palm hearts have also popular abroad, usually in fine dining establishments. However, palm hearts are cut-out of the inner core of various palm tree species, in some cases killing the tree. A new study published in mongabay.com's open access journal Tropical Conservation Society looks at the sustainability of palm heart extraction from the palm species Prestoea acuminata in the Colombian Andes. While harvesting from Prestoea acuminata does not kill the host tree, better management is needed to ensure the practice doesn't become unsustainable.
Estimating the rich diversity of galling insects
(12/12/2011) How does one estimate the number of tiny, cryptic "galling" insects without finding and describing every one (a task that could take centuries of taxonomic work)? According to a new paper in mongabay.com's open access journal Tropical Conservation Science, you count the plants. Galling insects use plant tissue for development creating a "gall," or abnormal growth on the plant. Such little-known insects include gall wasps, gall midges, aphids, and jumping plant lice. The groups are known to be highly diverse, with over 2,000 species described from the US alone; scientists have previously estimated that there may be as many as 132,000 different species.
Madagascar tree diversity among the highest worldwide
(12/12/2011) In terms of biodiversity, the hugely imperiled forests of Madagascar may be among the world's richest. Researchers estimate that the island off the coast of Africa is home to at least 10,000 tree and shrub species with over 90 percent of them found no-where else in the world. With little baseline data collected on Madagascar's ecosystems, a new study, the first ever of tree diversity in Madagascar lowland rainforests, hopes to begin the process. Published in mongabay.com's open access journal Tropical Conservation Science, the new study surveyed tree species in eastern Madagascar's Betampona Special Reserve.
Zoopharmacognosy: how self-healing animals could save humans
(11/27/2011) As humans we take many things for granted. When we come down with a sore throat, a fever, or the dreaded stomach flu, we drag our aching bodies into our cars and visit the doctor. Animals have no such luxury. Instead they have mastered evolution and have acquired an innate knowledge of the plants, soils, minerals, algae, and other remedies that nature offers to heal their aches and pains.
One night only: new orchid species surprises scientists
(11/22/2011) A mysterious new orchid blooms for one night only, opening around 10 PM and closing at 10 AM. Discovered on the island of New Britain near Papua New Guinea, the new species is the world's first orchid that flowers only at night. Scientists found the new flower, named Bulbophyllum nocturnum, in a logging concession on the tropical island.
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.
Picture of the day: quiet river in the woods
(11/13/2011) A river and forest in Gooseberry Falls State Park in the US state of Minnesota. The forest here is made up primarily of evergreens, aspen, and birch.
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.
Picture of the day: bromeliads in a cloud forest
(10/25/2011) These bromeliads of the cloud forests of the Andes are epiphytes. While they grow on other plants, in these cases trees, they are not parasitic.
Dam puts wild coffee species at risk of extinction
(09/26/2011) Coffee may be one of the world's most popular hot (and cold) drinks, however few coffee drinkers may know that there are dozens of different coffee species in the world and some are even endangered. Only discovered in 2004, Kihansi coffee (Coffea kihansiensis), makes its home in the Udzungwa Mountains of Tanzania. A new study in mongabay.com's open-access journal Tropical Conservation Science finds that the Kihansi coffee is nearing extinction due in part to a hydroelectric dam built upstream that has severely impacted the Kihansi River.
How fruit defines Borneo
(08/01/2011) Among conservationists and biologists, the mega-island of Borneo is a sort of Mecca. Its rich plant and animal biodiversity, as well as high degree of endemism (unique species found nowhere else) make it a naturalist's dream. There is one aspect of this biological richness which applies to the wellbeing and happiness of all of Borneo’s residents, human and animal, in a very direct way: fruit. From wild forest berries to juicy cultivated rambutans, fruit permeates the ecology, landscape and culture of Borneo. On the island there are over 70 wild fruit trees species and around 45 cultivated species that are consumed by people (1). Science has certainly not yet documented all the fruit consumed by wildlife, but we know that the total must be over 500 species.
Yellowstone burning: big fires to hit world's first national park annually by 2050
(07/25/2011) An icon of conservation and wilderness worldwide, Yellowstone National Park could see its ecosystem flip due to increased big fires from climate change warn experts in a new study in the Proceedings of the National Academy of Science (PNAS). A sudden increase in large fires—defined as over 200 hectares (500 acres)—by mid-century could shift the Yellowstone ecosystem from largely mature conifer forests to younger forests with open shrub and grasslands.
Decline in top predators and megafauna 'humankind’s most pervasive influence on nature'
(07/14/2011) Worldwide wolf populations have dropped around 99 percent from historic populations. Lion populations have fallen from 450,000 to 20,000 in 50 years. Three subspecies of tiger went extinct in the 20th Century. Overfishing and finning has cut some shark populations down by 90 percent in just a few decades. Though humpback whales have rebounded since whaling was banned, they are still far from historic numbers. While some humans have mourned such statistics as an aesthetic loss, scientists now say these declines have a far greater impact on humans than just the vanishing of iconic animals. The almost wholesale destruction of top predators—such as sharks, wolves, and big cats—has drastically altered the world's ecosystems, according to a new review study in Science. Although researchers have long known that the decline of animals at the top of food chain, including big herbivores and omnivores, affects ecosystems through what is known as 'trophic cascade', studies over the past few decades are only beginning to reveal the extent to which these animals maintain healthy environments, preserve biodiversity, and improve nature's productivity.
Elephants: the gardeners of Asia's and Africa's forests
(04/25/2011) It seems difficult to imagine elephants delicately tending a garden, but these pachyderms may well be the world's weightiest horticulturalist. Elephants both in Asia and Africa eat abundant amounts of fruit when available; seeds pass through their guts, and after expelled—sometimes tens of miles down the trail—sprouts a new plant if conditions are right. This process is known by ecologists as 'seed dispersal', and scientists have long studied the 'gardening' capacities of monkeys, birds, bats, and rodents. Recently, however, researchers have begun to document the seed dispersal capacity of the world's largest land animal, the elephant, proving that this species may be among the world's most important tropical gardeners.
Giant fish help grow the Amazon rainforest
(04/12/2011) A fruit in the flooded Amazon falls from a tree and plops in the water. Before it can even sink to the floor, a 60-pound monster fish with a voracious appetite gobbles it. Nearly a week later—and miles away—the fish expels its waste, including seeds from the fruit eaten long ago and far away. One fortunate seed floats to a particularly suitable spot and germinates. Many years later the new fruit tree is thriving, while the same monster-fish returns from time-to-time, waiting for another meal to drop from the sky. This process is known as seed-dispersal, and while researchers have studied the seed-dispersal capacity of such species as birds, bats, monkeys, and rodents, one type of animal is often overlooked: fish.
The value of the little guy, an interview with Tyler Prize-winning entomologist May Berenbaum
(04/06/2011) May Berenbaum knows a thing or two about insects: in recognition of her lifelong work on the interactions between insects and plants, she has had a character on The X-Files named after her, received the Public Understanding of Science and Technology Award for her work in making science accessible to the public, and this year has been awarded the prestigious Tyler Environmental Prize. "Winning the Tyler Prize is an incredible honor—most of my scientific heroes have been Tyler Prize winners and I’m exceedingly grateful to be considered worthy of being included among their ranks," Berenbaum told mongabay.com in an interview. "The Prize is also tremendously enabling—because the money is unrestricted I can use it to carry out projects that have been difficult to fund."
'Luck and perseverance': new plant genus discovered in Amazon
(03/31/2011) The discovery of a new plant species is not uncommon, especially in places of remarkable biodiversity such as the Amazon rainforest. However, discovering a new plant genus, a taxonomic rank above species, is, according to Henk van der Werff fromt the Missouri Botanical Garden (MBG), "a matter of luck and perseverance". Researchers with the Missouri Botanical Garden have been blessed with both as they have announced two new species of Amazonian plants, one from Ecuador and one from Peru, that comprise a completely new genus: named, Yasunia, since the plant was originally discovered in Ecuador's vast Yasuni National Park.
'Huge reduction' of water from plants due to higher carbon levels
(03/30/2011) As if ocean acidification and a warming world weren't enough, researchers have outlined another way in which carbon emissions are impacting the planet. A new study shows that higher carbon dioxide levels in the atmosphere have taken a toll on how much water vapor plants release, potentially impacting the rainfall and groundwater sources. A study in the Proceedings of the National Academy of Sciences (PNAS) has found that carbon dioxide levels over the past 150 years has reduced plants' spores, called stomata, by over one third (34%). This is important because stomata take in oxygen and carbon dioxide and release water vapor in a process dubbed 'transpiration'. Less stomata means less water driven into the atmosphere.
Leaf harvesting impacts Amazon palm
(03/28/2011) Overexploitation of wildlife doesn't just threaten animals such as bluefin tuna, pangolins, and parrots, but plants as well. Leaves from the carana or puy palm (Lepidocaryum tenue) are used for thatching buildings in the northwestern Amazon, however a recent study in mongabay.com's open access journal Tropical Conservation Science finds that the overharvesting could imperil a palm's ability to survive.
Logged forests in Vietnam retain significant biodiversity, including dipterocarp trees
(03/28/2011) Little remains of Vietnam's primary forest: as of 2005 only 12% of Vietnam forest was classified as primary. While deforestation rates have lessened since the end of the 1990s, survival of species in Vietnam depends in part on secondary, logged, and degraded forests. A new study in mongabay.com's open access journal Tropical Conservation Science finds that logged forests in southern Vietnam still retain significant biodiversity of trees, including important conservation species, such as Dipterocarp trees.
How to save the Pantanal and increase profits for the cattle industry
(03/28/2011) The Pantanal spanning Brazil, Bolivia, and Paraguay is the world's largest wetland—the size of Florida—and home to a wide-variety of charismatic species, such as jaguars, capybaras, and giant anteaters. However, the great wetland is threatened by expansion in big agriculture and an increasingly intensive cattle industry. Yet there is hope: a new study by Wildlife Conservation Society of Brazil (WCS-Brazil) researchers has found that cattle and the ecosystem can exist harmoniously. By replacing current practices with rotational grazing, cattle ranchers gain a healthier herd and more profits while safeguarding the ecological integrity and wildlife of the world's largest wetland system. The study published in mongabay.com's open access journal Tropical Conservation Science is a rare instance of a win-win situation.
Alien plants invade Nigerian protected 'gene bank'
(03/28/2011) Very few studies have been conducted on invasive species in Nigeria, however a new study in mongabay.com's open access journal Tropical Conservation Science has discovered 25 invasive plants in a field gene bank at the National Center for Genetic Resources and Biotechnology (NASGRAB) in Ibadan. The gene bank is used to establish populations of important and, in some cases threatened, native plant species. The gene bank spans 12 hectares, but the study found that 18% of the area was overtaken with invasive species that likely compete with the protected Nigerian plants for nutrients, space, and light. Among the 25 invasive species, 14 were herbs, 8 were vines, 2 were shrubs, and one was a tree.
Rich plant diversity leads to increased productivity, ecosystem services
(03/08/2011) A new study finds that diversity of plant species matters—big time. Analyzing nearly 600 research studies, the meta-study in the American Journal of Botany found that productivity in biodiverse plant ecosystems was 1.5 times higher than in monocultures. In other words, a prairie is more productive than a cornfield and forest more productive than a rubber plantation. The researchers warn that eroding plant diversity threatens essential ecosystems services such as food, water purification, oxygen production, carbon sequestration, and the availability of raw materials.
Not enough data on world's tropical plants to predict impact of warming world
(02/14/2011) How many tropical plant species are threatened by climate change? Which plants have big enough ranges to survive a warming world, not to mention deforestation? How likely is it that the tropics are undergoing a current mass extinction? These questions may appear straight forward, but a new study in Global Change Biology finds that researchers lack the hard data necessary to come to any confident conclusions. According to the study, nine out of ten tropical plants from Africa, Asia, and South America lack the minimum number of collections needed (at least 20) to determine the species' range, and therefore predict the impact of climate change.
Vines rising in the Amazon and other American rainforests
(02/14/2011) For years tropical scientists have anecdotally reported an increase in vines in the Amazon and other American tropical forests, but now a number of studies have confirmed such reports: vines are on the rise in Neotropical rainforests.
From Cambodia to California: the world's top 10 most threatened forests
(02/02/2011) Growing populations, expanding agriculture, commodities such as palm oil and paper, logging, urban sprawl, mining, and other human impacts have pushed many of the world's great forests to the brink. Yet scientists, environmentalists, and even some policymakers increasingly warn that forests are worth more standing than felled. They argue that by safeguarding vulnerable biodiversity, sequestering carbon, controlling erosion, and providing fresh water, forests provide services to humanity, not to mention the unquantifiable importance of having wild places in an increasingly human-modified world. Still, the decline of the world's forests continues: the FAO estimating that around 10 million hectares of tropical forest are lost every year. Of course, some of these forests are more imperiled than others, and a new analysis by Conservation International (CI) has catalogued the world's 10 most threatened forests.
Tiny bats trade in caves for pitcher plants in Borneo
(01/26/2011) A tiny species of bat in Borneo has chosen an unusual roost: a carnivorous pitcher plant, according to a recent study. The study examines how this behavior actually benefits both the bats and the plants, creating a symbiotic relationship.
World's weirdest aphrodisiac: elephant-digested durian fruit
(01/20/2011) The spiky, odorous, weighty, and almost impenetrable durian fruit is considered by some to be a fine delicacy, but others a putrid horror. Its taste has been described between a delicious custard and old gym socks. Still, even durian lovers may be uncomfortable with the idea of eating the fruit after it has been consumed and expelled by a wild Asian elephant. But according to the New Straits Times recently wealthy businessmen are willing to pay over $300 for a sample of elephant-ingested durian, which they believe acts as an aphrodisiac.
Forgotten species: the plummeting cycad
(12/06/2010) I have a declarative statement to make: cycads are mind-blowing. You may ask, what is a cycad? And your questions wouldn't be a silly one. I doubt Animal Planet will ever replace its Shark Week with Cycad Week (perhaps the fact that it's 'animal' planet and not 'plant' planet gave that away); nor do I expect school children to run to see a cycad first thing when they arrive at the zoo, rushing past the polar bear and the chimpanzee; nor do I await a new children's book about a lonely little anthropomorphized cycad just looking for a friend. In the world of species-popularity, the cycad ranks pretty low. For one thing, it's a plant. For another thing, it doesn't produce lovely flowers. And for a final fact, it looks so much like a palm tree that most people probably wouldn't know it wasn't. Still, I declare the cycad to be mind-blowing.
Slight rise in mangrove forests in Eastern India
(11/29/2010) While mangrove forests are vanishing around the world, the Indian Ministry of Environment and Forests is reporting a slight uptick of mangrove forests along the nation's eastern coast. According to a report, mangroves expanded from 4,581 square kilometers in 2005 to 4,639 square kilometers in 2007, an increase of 58 square kilometers.
Botanist killed in crossfire in Philippines
(11/17/2010) A local botanist was killed in crossfire between the Filipino military and suspected communist guerrillas with the New People's Army on Monday, reports the Inquirer.net.
Photographer discovers new species of meat-eating plant in Cambodia
(11/16/2010) British photographer Jeremy Holdren recently discovered a new species of carnivorous pitcher plant in Cambodia's Cardamom Mountains during a survey with Fauna & Flora International (FFI).
What do wolves and sharks have in common?
(11/15/2010) Sharks dwell in the ocean, wolves on land; sharks are a type of fish, wolves are a mammal; sharks go back some 400 million years, wolves only some 2 million years. So, these animals should have little in common, right? However, a new study in Frontiers in Ecology and the Environment points to surprising similarities among these disparate animals. As top predators, both wolves and sharks impact their prey and other species in similar ways.
Critics say Obama slow on endangered species
(11/15/2010) The Obama Administration is lagging behind past administrations in its listing of dwindling species under the Endangered Species Act (ESA). To date the US Fish and Wildlife Service has added 51 species to the ESA since Obama's took office, according to the conservation group, Center for Biological Diversity. By contrast, the Clinton Administration averaged 65 species a year with a total of 522 species protected. Obama is more proactive than George W. Bush, however, who was seen by many critics as actively undercutting the ESA. Only one of the species protected so far by the Obama Administration is found in the continental US.
Eight new plants discovered in Bolivia
(11/07/2010) Researchers have described eight new species of plant from in and near Madidi National Park in the Bolivian Andes. Described in the journal Novon by botanists with the Missouri Botanical Garden and the National Herbaium in Laz Paz, Bolivia, seven of the eight plants were found as apart of the Proyecto Madidi (Project Madidi), a ten year effort to describe the plant species of three inter-connecting protected areas in Bolivia—Madidi National Park, Pilón Lajas Biosphere Reserve and Communal Lands, and Apolobamba Integrated Management Natural Area.
Bushmeat hunting alters forest structure in Africa
(11/04/2010) According to the first study of its kind in Africa, bushmeat hunting impacts African rainforests by wiping-out large mammals and birds—such as forest elephants, primates, and hornbills—that are critical for dispersing certain tree species. The study, published in Biotropica, found that heavy bushmeat hunting in the Central African Republic changes the structure of forest species by favoring small-seeded trees over large-seeded, leading to lower tree diversity of trees that have big seeds.
Monarch butterflies medicate their sick kids
(10/12/2010) A new study in Ecology Letters has discovered that monarch butterflies employ medicinal plants to treat their larva. Researchers found that certain species of milkweed, which the larva feed on, can reduce the threat of a sometime deadly parasite. However, even more surprising: "we have also found that infected female butterflies prefer to lay their eggs on plants that will make their offspring less sick, suggesting that monarchs have evolved the ability to medicate their offspring," says lead author Jaap de Roode.
Photos: 200 new species discovered in 60-day expedition in New Guinea
(10/06/2010) A 2009 expedition to Papua New Guinea proves once again that the island-nation is as diverse in life as it is in human cultures. It took researchers with Conservation International (CI) and the local Institute for Biological Research (IBR) just two months to uncover a startling 200 new species: averaging more than 3 a day in the remote Nakanai Mountains and Muller Range rising from the island of New Britain, a part of Papua New Guinea. Half of the new species were spiders, but the team also found two new mammals, nine new plants, two dozen frogs, and multitude of insects. Most surprising was the discovery of at least two species so unique that they are likely to be assigned their own genus.
Losing nature's medicine cabinet
(10/04/2010) In all the discussions of saving the world's biodiversity from extinction, one point is often and surprisingly forgotten: the importance of the world's species in providing humankind with a multitude of life-saving medicines so far, as well as the certainty that more vital medications are out there if only we save the unheralded animals and plants that contain cures unknown. Already, species have provided humankind everything from quinine to aspirin, from morphine to numerous cancer and HIV-fighting drugs. "As the ethnobotanist Dr. Mark Plotkin commented, the history of medicine can be written in terms of its reliance on and utilization of natural products," physician Christopher Herndon told mongabay.com. Herndon is co-author of a recent paper in the journal Biotropica, which calls for policy-makers and the public to recognize how biodiversity underpins not only ecosystems, but medicine.
Mass extinction fears widen: 22 percent of world's plants endangered
(09/28/2010) Scientific warnings that the world is in the midst of a mass extinction were bolstered today by the release of a new study that shows just over a fifth of the world's known plants are threatened with extinction—levels comparable to the Earth's mammals and greater than birds. Conducted by the Royal Botanic Gardens, Kew; the Natural History Museum, London; and the International Union for the Conservation of Nature (IUCN), the study is the first time researchers have outlined the full threat level to the world's plant species. In order to estimate overall threat levels, researchers created a Sampled Red List Index for Plants, analyzing 7,000 representative species, including both common and rare plants.
Ugandan forest being stripped for fuel wood
(09/27/2010) A new study in the open access journal of Tropical Conservation Science finds that the Kasagala forest reserve in central Uganda is losing important tree species and suffering from low diversity of species. Researchers believe that forest degradation for charcoal and firewood has put heavy pressure on this ecosystem.
The effect of forest regeneration strategies on beetles
(09/27/2010) As conservationists attempt to find the best way to re-establish forests in abandoned areas, a new study in the open-access journal Tropical Conservation Science compares the impacts on bess beetles of different method to regeneration forest. Bess beetles are important dead wood-recyclers in the forest. Looking at three different forests in the Colombian Andes—natural regeneration, monoculture reforestation, and an old-growth forest as a baseline—researchers found that old-growth and natural regeneration had the highest diversity of bess beetles, while old-growth sported the greatest abundance of beetles.
Indian carnivore eats mostly fruit
(09/27/2010) When is a carnivore no longer a carnivore? A new study in mongabay.com's open access journal Tropical Conservation Science has found that the brown palm civet (Paradoxurus jerdoni), a cat-sized tree-loving carnivore, lives almost entirely off fruit and seeds. Studying over a 1000 feces from the brown palm civet during three years, researchers found that 97 percent of its diet was composed of plants, not meat. Given its penchant for fruit, researchers argue that the brown palm civet is an important disperser of tropical plants, playing a vital ecological role rarely connected to civets.
Plant names cut by over half a million
(09/22/2010) Researchers expect to strike out some 600,000 plant species names from taxonomy lists, representing over half of the names in current lists which stretched to nearly a million. The names cut are duplicate monikers for the same plant: for example, researchers discovered an astounding 800 different names for the tomato (Solanum lycopersicum). Researchers are once-and-for-all weeding out alias names in an attempt to create a single definitive list of plant names.
How the overlooked peccary engineers the Amazon, an interview with Harald Beck
(09/20/2010) When people think of the Amazon rainforest, they likely think of roaring jaguars, jumping monkeys, marching ants, and squeezing anacondas. The humble peccary would hardly be among the first animals to cross their mind, if they even know such pig-like animals exists! Yet new research on the peccary is proving just how vital these species are to the world's greatest rainforest. As seed dispersers and seed destroyers, engineers of freshwater habitats and forest gaps, peccaries play an immense, long overlooked, role in the rainforest. "Peccaries have the highest density and biomass of any Neotropical mammal species. Obviously these fellows have quite an appetite for almost anything, but primarily they consume fruits and seeds. Their specialized jaws allow them to crush very hard seeds. The cracking sounds can be heard through the thick vegetation long before we could see them. As peccary herds bulldoze through the leaf litter in search for insects, frogs, seeds, and fruits, they destroy (i.e. snap and trample) many seedlings and saplings, sometimes leaving only the bare ground behind," Harald Beck, assistant professor at Towson University in Maryland, told mongabay.com in an interview.
Exploring Kenya's sky island
(08/18/2010) Rising over 2,500 meters from Kenya's northern desert, the Mathews Range is a sky island: isolated mountain forests surrounded by valleys. Long cut off from other forests, 'sky islands' such as this often contain unique species and ecosystems. Supported by the Nature Conservancy, an expedition including local community programs Northern Rangelands Trust and Namunyak Conservancy recently spent a week surveying the mountain range, expanding the range of a number of species and discovering what is likely a new insect.
Visiting the Gulf: how wildlife and people are faring in America's worst environmental disaster, an interview with Jennifer Jacquet
(07/29/2010) "President Obama called it 'the worst environmental disaster America has ever faced.' So I thought I should face it and head to the Gulf"—these are the opening words on the popular blog Guilty Planet as the author, marine biologist Jennifer Jacquet, embarked on a ten day trip to Louisiana. As a scientist, Jacquet was, of course, interested in the impact of the some four million barrels of oil on the Gulf's already depleted ecosystem, however she was as equally keen to see how Louisianans were coping with the fossil fuel-disaster that devastated their most vital natural resource just four years after Hurricane Katrina.
Backbone of marine food chain in alarming decline
(07/28/2010) Tiny marine algae, known as phytoplankton, are the backbone of the marine food chain, yet a new study in Nature has found that this backbone is disintegrating. Researchers discovered that since 1950 phytoplankton has declined by approximately 40 percent across the Northern Hemisphere, a decline that corresponds to warming waters due to climate change. Given that phytoplankton feed the oceans' abundance all the way up the food chain—from zooplankton to fish to seabird to sharks to humans—the decline has likely impacted the very structure of the ocean.
Australian rainforest plant yields possible cancer killer
(06/14/2010) A drug derived from a plant native to the Australian rainforest may prove to be a new weapon against cancer, according to the AFP. QBiotics Ltd has released a statement announcing that a drug made from the seeds of a rainforest shrub has successfully treated tumors in over 150 animals, and the company is now preparing to test the drug on humans.
When nature saves your life
(06/14/2010) If someone saves your life, you want to express your gratitude however you can -- a gesture, a "thank you,", or somehow returning the favor. Yet when you owe your life to a plant found thousands of miles away, the task becomes much harder. As a nurse, I’ve known for years that many life-saving medicines come from plants and animals found around the world. But I never thought that one day I would have to rely on the bark of a rare Asian tree to survive.
