(03/27/2014) In 1864, Walter Campbell was an officer in the British Army, stationed in India when he penned these words in his journal: "Never attack a tiger on foot—if you can help it. There are cases in which you must do so. Then face him like a Briton, and kill him if you can; for if you fail to kill him, he will certainly kill you." In a stroke of good fortune for the tiger, perceptions in India have changed drastically since Campbell's time. Tiger hunting is now banned and conservationists are usually able to rescue the big cats if they become stranded while navigating increasingly human-occupied areas. But is this enough to save the tiger?
Europe approves vet drug that killed off almost all of Asia's vultures
(03/25/2014) When Europeans first arrived in North America, they exterminated three to five billion passenger pigeons (Ectopistes migratorius) in the short span of a century through a combination of habitat destruction and hunting. In 1914, the last living passenger pigeon perished at the Cincinnati Zoo. Despite the staggering scale of this extinction event, three species of vulture from Southeastern Asia retain the dubious distinction of having had the most rapid population crash of any avian fauna. They might not have begun with numbers as large as the passenger pigeon, but within the space of a single decade, their populations were reduced by 96 to 99 percent.
Over 9,000 primates killed for single bushmeat market in West Africa every year
(03/24/2014) Over the past 25 years, West Africa's primates have been put at risk due to an escalating bushmeat trade compounded with forest loss from expanding human populations. In fact, many endemic primates in the Upper Guinea forests of Liberia and Ivory Coast have been pushed to the verge of extinction. To better understand what’s happening, a recent study in mongabay.com's open-access journal Tropical Conservation Science investigated the bushmeat exchange between these neighboring countries.
Indigenous people witness climate change in the Congo Rainforest
(03/20/2014) Indigenous communities in the Republic of Congo are observing climate change even though they have no knowledge of the science, according to a unique collaboration between the Rainforest Foundation UK (RFUK) and local communities. The environmental changes witnessed by the locals in the Congo rainforest include increased temperature, less rainfall and alterations to the seasons, much as expected under global climate change.
Leftover trees enhance the biodiversity of new forests
(03/18/2014) Trees left standing after deforestation have a discernible impact on the composition of local biodiversity in secondary growth forests, according to a new study published in PLOS ONE. Researchers working on the Osa Peninsula in Costa Rica discovered that remnant trees could affect species composition of regenerated forests up to 20 years after being logged.
Frog creates chemical invisibility cloak to confuse aggressive ants
(03/14/2014) The African stink ant creates large underground colonies that are home to anywhere from hundreds to thousands of ants, and occasionally a frog or two. The West African rubber frog hides in the humid nests to survive the long dry season of southern and central Africa. However, the ant colonies are armed with highly aggressive ant militias that fight off intruders with powerful, venomous jaws. So how do these frogs escape attack?
Mountain thermostats: scientists discover surprising climate stabilizer that may be key to the longevity of life on Earth
(03/14/2014) What do mountains have to do with climate change? More than you'd expect: new research shows that the weathering rates of mountains caused by vegetation growth plays a major role in controlling global temperatures. Scientists from the University of Oxford and the University of Sheffield have shown how tree roots in certain mountains "acted like a thermostat" for the global climate.
Can penguins cope with climate change? Scientists find different types of ice elicit different responses
(03/13/2014) Human-caused climate change is altering the habitat of Adélie penguins (Pygoscelis adeliae). In an article recently published in PLOS ONE, a team of researchers led by Amélie Lescroël from the Centre d'Ecologie Fonctionnelle et Evolutive (CNRS) in France, found that changes in sea-ice content and newly formed icebergs significantly impacted Adélie penguin communities in the Ross Sea.
The fungus among us: scientists discover a big player in the global carbon cycle
(03/12/2014) Carbon counters trying to keep tabs on the rising concentration of carbon dioxide in our atmosphere may have missed an important factor for their estimates: fungus. It turns out that when plants partner up with certain types of fungi, they can store up to 70 percent more carbon in the soil according to a paper published last month in Nature by Colin Averill and scientists at the Smithsonian Tropical Research Institute.
Cocaine: the new face of deforestation in Central America
(03/11/2014) In 2006, Mexico intensified its security strategy, forming an inhospitable environment for drug trafficking organizations (also known as DTOs) within the nation. The drug cartels responded by creating new trade routes along the border of Guatemala and Honduras. Soon shipments of cocaine from South America began to flow through the Mesoamerican Biological Corridor (MBC). This multi-national swathe of forest, encompassing several national parks and protected areas, was originally created to protect endangered species, such as Baird's Tapir (Tapirus bairdii) and jaguar (Panthera onca), as well as the world's second largest coral reef. Today, its future hinges on the world's drug producers and consumers.
Local knowledge sheds light on some of the world's strangest mammals
(03/07/2014) One of the difficulties of studying rare and endangered species is that they are, by definition, hard to find. Scientists attempting to understand their distributions and the threats to their survival can spend hundreds of hours in the field while collecting little data, simply because sightings are so few and far between.
Can the millions in urban India live among greenery?
(03/06/2014) Large swathes of wilderness alternating with pockets of urbanization may be a reality in some countries, but in India boundaries are soft. Where a city ends and where a village begins in its outskirts is somewhat fuzzy. Rapidly developing megacities like Bangalore and Pune, localities like Gurgaon outside New Delhi, have been subsuming surrounding villages into their ever-expanding boundaries for the last couple of decades.
Scientists uncover new species of Andean marsupial frog
(03/05/2014) The term marsupial frog sound like a hoax, but, believe it or not, it's real. Recently, herpetologists welcomed a new species, known as Gastrotheca dysprosita and described in the journal Phyllomedusa. Unlike mammal marsupials, which typically carry their young in pouches on their torsos and are found primarily in Australia, the Gastrotheca genus of frogs, which contains 62 species, is found in the Andes region on South America and sport their pouches on their backs (also called a "dorsal brood pouch").
The real cost of conservation: cheap protection rarely succeeds
(03/03/2014) Conservation efforts in less-developed and politically unstable countries are full of risk, according to a study published in PLOS ONE. The study, which looks at how to best evaluate conservation priorities, argues that selecting priority countries based solely on economic factors may lead to failure in conservation projects and increase the likelihood of negative impacts on local people.
Saving sharks one sandwich at a time: conservationists target 'shark bake'
(02/28/2014) Thousands of Carnival revelers in Trinidad wouldn't think of missing the chance to go to Maracas Beach, the most famous strip of sand on the small Caribbean island off the northeast coast of Venezuela. Beachgoers might not think twice about eating a favorite food called "shark bake" either – at least, until now. But this week, conservationists launched a shark-saving campaign timed to get maximum exposure out of the celebration that will bring throngs of visitors to the island.
Plastic waste ingested by worms threatens marine food chains
(02/26/2014) Small fragments of plastic waste are damaging the health of lugworms, putting a key cog in marine ecosystems at risk. Published in Current Biology, a new study by scientists at the University of Exeter and the University of Plymouth shows the impact of microplastics on the marine worms' health and behavior.
Corals thriving despite acidified conditions in remote Pacific bay
(02/25/2014) Scientists have discovered a small island bay in the Pacific which could serve as a peephole into the future of the ocean. Palau's Rock Island Bay harbors a naturally occurring anomaly – its water is acidified as much as scientists expect the entire ocean to be by 2100 as a result of rising carbon dioxide emissions.
Will tigers march ahead? Scientists find surprising connections between isolated populations in Central India
(02/25/2014) In May 2011, a young male Bengal tiger (Panthera tigris tigris) made its way to a village in the state of Karnataka in India. The tiger had been quite a hiker. To reach the village, it had walked more than 280 kilometers (174 miles) from Bandipur Tiger Reserve, a protected area famous for these elusive big cats.
Ocean acidifying 10 times faster than anytime in the last 55 million years, putting polar ecosystems at risk
(02/24/2014) An assessment of ocean acidification, presented at the UN Climate Change Conference in Warsaw in November 2013, starkly concluded that acidity is on track to rise 170 percent by the end of this century. As many key species are sensitive to changes in acidity, this would drastically impact ocean ecosystems, with effects especially pronounced in polar regions where the cold waters intensify acidification, and which are home to many organisms that are particularly vulnerable to acidification.
Two new wasp species found hidden in museum collections
(02/24/2014) Scientists have identified two new wasp species, years after the specimens were first collected from the wild. The two new species, Abernessia prima and Abernessia capixaba, belong to the rare pompilid genus Abernessia, and are believed to be endemic to Brazil. They made the discovery while examining spider wasp collections from museums in Brazil and Denmark, and published their findings in the journal ZooKeys.
Why are the tropics so rich with life?
(02/24/2014) Descending the latitudinal ladder to the tropics, you would likely notice a few things: increasingly equivalent stretches of day and night, warmer weather and beachgoers with more intense sunburns. You may also notice an abundance of plant and animal life. Generations of scientists since the days of Darwin and Wallace have observed that species richness increases as one moves toward the equator. This holds true for nearly every animal group, including micro-organisms, marine invertebrates, insects, amphibians, birds and mammals. But why is this?
Traditional palm knowledge at risk of becoming lost forever
(02/21/2014) The humid tropical forests of northwestern South America boast over 140 different palm species (Arecaceae), yet the people who dwell underneath these green canopies and the knowledge they posses remain relatively unknown to modern science. But Rodrigo Cámara-Leret of the Autonomous University of Madrid and his team of researchers are working to change that by documenting and preserving the traditional knowledge of palms before it is forgotten and lost forever.
The making of Amazon Gold: once more unto the breach
(02/19/2014) When Sarah duPont first visited the Peruvian Amazon rainforest in the summer of 1999, it was a different place than it is today. Oceans of green, tranquil forest, met the eye at every turn. At dawn, her brain struggled to comprehend the onslaught of morning calls and duets of the nearly 600 species of birds resounding under the canopy. Today, the director of the new award-winning film, Amazon Gold, reports that "roads have been built and people have arrived. It has become a new wild west, a place without law. People driven by poverty and the desire for a better life have come, exploiting the sacred ground."
Scientists discover new gecko hanging-on in single forest fragment
(02/17/2014) Scientists have identified a new species of day gecko that is the largest in its genus (Cnemaspis) to be found in Sri Lanka. To date, it has been observed only within the Rammalakanda Reserve in southern Sri Lanka, an area spanning just 1,700 hectares, raising questions about the viability of this population and hence the species' long-term prospects.
Local communities key to saving the Critically Endangered Mexican black howler monkey
(02/14/2014) For conservation initiatives around the world, community involvement is often crucial. An additional challenge is how to conserve species once their habitats have become fragmented. A primatologist in Mexico is bringing these together in a celebration of a Critically Endangered primate species: the Mexican black howler monkey. In 2013 Juan Carlos Serio-Silva was part of a team that not only helped to secure the establishment of a protected area for the Mexican black howler monkey, but also engaged local communities in a week of festivities, dubbed the First International Black Howler Monkey Week.
Alpine bumblebees capable of flying over Mt. Everest
(02/05/2014) The genus Bombus consists of over 250 species of large, nectar-loving bumblebees. Their bright coloration serves as a warning to predators that they are unwelcome prey and their bodies are covered in a fine coat of hair - known as pile - which gives them their characteristically fuzzy look. Bumblebees display a remarkably capable flight performance despite being encumbered with oversized bodies supported by relatively diminutive wings.
How hunters have become key to saving Bulgaria's capercaillie
(02/04/2014) Surprising clatter cuts through the silence in the snowy forest shortly before sunrise. The powerful clicking sounds like a dropping Ping-Pong ball before culminating in a loud pop resembling the opening of a champagne bottle. This sound is heard clearly and far. Propped on a thick pine tree branch, with a peacock-fanned tale, relaxed wings and head pointing skyward, a western capercaillie is singing. The song terminates with a low-frequency sound similar to scraping a fork to the bottom of a frying pan. It's exactly during those last few moments of singing that something unusual happens: the male bird goes temporarily deaf. Hence the species' common name in Bulgarian—deaf bird.
Protected forests linked to healthy coral reefs in Fiji
(01/27/2014) Increasing forest protection in the right areas could increase benefits up to 10.4 percent to coral reef condition, according to a recent study of Fiji's forests and reefs in Marine Policy. Benefits from protected forests such as improved water quality due to decreased runoff and increased distribution of the vegetation are more closely linked to coral reef health than previously thought.
Next big idea in forest conservation? Using drones to catch poachers, monitor forests
(01/24/2014) At the foothills of the Himalayas, elephants, rhinoceroses, and tigers stir in the green forests. Protecting and monitoring these animals and the health of tropical forests worldwide is a significant challenge, often requiring large amounts of time, money and risk. Fortunately, an affordable new tool is soaring into the conservation sphere: autonomous flying vehicles, or drones. Lian Pin Koh, is a founding director of the non-profit ConservationDrones.org, which builds capacity in the use of drones for conservation in the developing tropics.
The next best thing: how well do secondary forests preserve biodiversity?
(01/23/2014) Secondary forests, which are areas that were previously cleared of old-growth cover, now comprise the majority of the forested areas in the United States, Europe, and elsewhere. A heavily debated issue is to what extent secondary forests are able to contribute to the preservation of biodiversity. In an article published in PLOS ONE, a group of researchers from the Smithsonian Tropical Research Institute led by Michiel van Breugel evaluated the biodiversity preservation potential of secondary forests.
How “insect soup” might change the face of conservation
(01/23/2014) Much of what we know about patterns of biodiversity has come from extensive fieldwork, with expert researchers sampling and identifying species in a process that takes thousands of man-hours. But new technologies may revolutionize this process, allowing us to monitor changes in biodiversity at speeds and scales unimaginable just a decade ago.
New frog species discovered on tallest mountain in Indochina
(01/22/2014) A team of Australian and Vietnamese researchers recently discovered a new species of frog in the high elevations of Vietnam’s Mount Fansipan, according to a new paper in Zootaxa. The amphibian was named Botsford’s leaf-litter frog (Leptolalax botsfordi) as a tribute to Christopher Botsford for his role in amphibian biodiversity research in Asia.
One lizard, four species: the collared treerunner
(01/21/2014) Now, that’s a horse of a different color. Or, in this case, a lizard of another species--four species. Recent research suggests that the collared treerunner (Plica plica), previously thought of as one widespread species, is actually four distinct species inhabiting diverse geographical areas east of the Andes in northern South America.
Spectacular new beetle discovered in French Guiana
(01/21/2014) The discovery of a new, bi-colored beetle species in the lowland rainforest of French Guiana just added a little pizzazz to the ranks of the Pseudomorphini tribe of beetles. With wing cases (elytra) that sport black spots against a rusty red background, the newcomer was dubbed Guyanemorpha spectabilis, or the spectacular Guyane false-form beetle, by entomologist Terry Erwin in the journal ZooKeys.
Handful of species key to ecosystem health, finds study
(01/20/2014) While conducting field research in the humid salt marshes of Sapelo Island, scientists Marc Hensel and Brian Silliman made an astonishing discovery: species type, not just quantity, is vital for maintaining healthy ecosystems. For decades, scientists believed that preserving the largest number of species was critical for ecosystem function, regardless of their genetic makeup.
For agoutis, the night is fraught with peril
(01/15/2014) In a study recently published in the online Animal Behavior journal, scientists from the US and the Netherlands have examined the impact of predation patterns on prey's food foraging habits. The two-year long study on Barro Colorado Island, Panama, focused on the predator-prey relationship between the Central American agouti (Dasyprocta punctata), a common rainforest rodent, and the ocelot (Leopardus pardalis).
Climate fail: Geoengineering would cool planet, but screw up rainfall patterns
(01/14/2014) For decades, scientists have been grappling with the consequences of climate change and working toward viable solutions. Climate engineering, also known as geoengineering, is the most controversial possible solution. Currently, one of the most talked about geoengineering ideas is Solar Radiation Management (SRM), which intends to block shortwave solar radiation, thus cooling the Earth to offset rising temperatures. In other words, SRM may be one way in which global temperatures could be artificially stabilized.
Primary school children build fuel-efficient stoves in Uganda
(01/10/2014) A group of young children have become a catalyst in the effort to save Kibale National Park from deforestation. Children from Iruhuura Primary School in Uganda have collaborated with the Kasiisi Project and Camp Uganda to build fuel-efficient stoves, developing a more sustainable method of wood consumption around the hugely-biodiverse Kibale National Park.
Tree islands more effective way to replant the world's forests
(01/09/2014) Worldwide, large swaths of land lay barren in the wake of agricultural expansion, and as global forest cover continues to decline, carbon and water cycles, biodiversity, and human health are impacted. But efforts to restore abandoned pastures and agricultural plots back into functioning forest ecosystems are often hindered by high costs and time requirements. Fortunately, scientists have developed a new method for a more cost effective solution to forest restoration, the establishment of 'tree islands.'
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.
Rewilding Chile's savanna with guanacos could increase biodiversity and livestock
(01/06/2014) Local extinctions have occurred across a variety of habitats on every continent, affecting a gamut of species from large predators such as the wolves of North America, to tiny amphibians like the Kihansi spray toad of Tanzania. The long trek toward reversing such extinctions has begun, but it is not without its challenges, both ethical and logistical.
Global warming could upset Antarctic food chain
(01/02/2014) Resting near the bottom of the foodchain, Antarctic krill (Euphausia superba) underpin much of the Southern Ocean's ecosystem. But in a rapidly warming world, these hugely-abundant crustaceans could see their habitat shrink considerably. In a recent paper in PLOS ONE, scientists predict that Antarctic krill could lose 20 percent of their growth habitat, or 1.2 million square kilometers.
Curious bears take 'selfies' with camera traps
(12/26/2013) "Selfies" are all the rage this year, and even bears have jumped on the trend. Especially the shaggy-coated, termite-loving sloth bears (Melursus ursinus), who seem particularly fascinated by the cameras that scientists have put up in forests to secretly capture their stealthy moves.
Jaguars in Argentine Chaco on verge of local extinction
(12/23/2013) The majestic jaguar (Panthera onca), the largest of the New World cats, is found as far north as the southern states of the US, and as far south as northern Argentina. In the past jaguars ranged 1,500 kilometers (930 miles) further south, but their range has shrunk as habitat loss and human disturbance have increased. Overall, jaguars are classified as Near Threatened by the IUCN, but the level of risk facing jaguars varies by region. Populations in Argentina, at the present-day southern range limit, have previously been identified as some of the most threatened of them all.
Unraveling the secrets of one of the world's most mysterious big cats
(12/22/2013) The Sunda clouded leopard has always been shrouded in mystery. Only declared a separate species from its mainland cousin, the Borneo clouded leopard, in 2006, the IUCN lists the cat as Endangered. The distinction between the Borneo clouded leopard (Neofelis nebulas) and the Sunda clouded leopard (Neofelis diardi) was made by ground-breaking molecular coding technologies and anatomy studies of the two species. Although it is Borneo's largest predator, very little is known about the Sunda leopard. As a medium-sized, well-camouflaged and mostly nocturnal animal, the leopard has evaded researchers since its discovery eight years ago.
Giant clams are easy to recognize, but genetics proves there is more than meets the eye
(12/21/2013) Giant clams are among the more easily spotted invertebrates of the marine realm. However, some are actually quite cryptic and distinct species are often difficult to identify, claims a study recently published in PlosOne. Much attention has been focused on charismatic species in research, but the scientists who authored the study argue that giant clams also deserve the spotlight because of the potential threats and present misunderstandings regarding their taxonimical classifications.
Scientists discover a new coral in the French Polynesia
(12/20/2013) With humans scattered throughout the globe, it is hard to imagine lands still unexplored or species undocumented. Yet, on the remote French Polynesian Gambier Islands a new coral reef species has been found thriving in underwater lagoons. Echinophyllia tarae was discovered by marine biologist Francesca Benzoni and the research crew members of the Tara Oceans International Research Expedition.
New marsupial discovered in Ecuador
(12/20/2013) Researchers working in Ecuador have identified a previously unknown species of shrew-opossum, according to a study recently published in the Journal of Mammalogy. Contrary to its mousey appearance, Caenolestes sangay, named after the national park where it was discovered, is actually a marsupial. The team from Pacific Lutheran University set up more than 100 live traps over 15 nights on the eastern slopes of Andes. In the course of their research they recovered five specimens of the new species, each measuring approximately 10 centimeters (3.9 inches) long.
Little elephant is the first scientific record of dwarfism in the wild
(12/19/2013) Biologists in Sri Lanka have published the first documented evidence of dwarfism in an adult wild animal. A male Asian elephant (Elephas maximus) measuring just over 1.5 meters (five feet) in height was seen in an aggressive encounter with another male of average size. The elephant's small stature was due to disproportionately short legs, according to the findings published in the IUCN/SSC Asian Elephant Specialist Group journal Gajah. "The 'dwarf' was by far the main aggressor in the altercation and appeared to be older than the other, a young adult," states the study. "Other than for the disproportionately short legs, morphologically and behaviorally the dwarf appeared normal."
Using stories to connect people to biodiversity: an interview with Tara Waters Lumpkin, PhD
(12/18/2013) In a world where extinctions are almost commonplace and global warming barely raises an eyebrow, very few of us can return to find the places we grew up in unsullied by development. Sometimes, all that is left of a favorite grove of trees or strip of forest are memories. Through Izilwane: Voices for Biodiversity Project, an online magazine for story-tellers, Tara Waters Lumpkin has succeeded in bringing together more than one hundred "eco-writers" who have shared their memories, highlighted environmental crises in their localities and raised their voices against habitat destruction.
Africa to build world's largest dam, but who will benefit?
(12/17/2013) The Congo River traverses the continent of Africa, ending its journey in the Democratic Republic of Congo (DRC) where it spills 1.5 million cubic feet per second into the Atlantic Ocean. Now, plans are underway to harness this tremendous force of water in what promises to be the world's largest hydropower scheme, The Grand Inga.
New Guinea animals losing vital tree cavities to logging, hunting practices
(12/17/2013) Across New Guinea, deforestation is occurring at increasing levels. Whether it be industrial logging, monoculture plantations, hunters felling trees in pursuit of arboreal wildlife, or other forms of forest conversion, deforestation is depleting not only forest carbon stocks and understory environments, but habitats for species who call tree cavities "home." A new study in mongabay.com's open-access journal, Tropical Conservation Science, evaluated whether a variety of man-made nest boxes could function as suitable substitutes for tree cavities.
Asian elephants depend on shifting cultivation during the dry season
(12/16/2013) Asian elephants (Elephas maximus) have co-existed with human practices for thousands of years, including shifting cultivation. Shifting agriculture encompasses a variety of different practices that involve abandoning plots for periods of time to allow natural vegetation to grow. The practice consists of cutting and burning the natural vegetation at the end of the dry season and cultivating with the rains. Harvesting is completed by the end of the wet season.
A bird's eye view of hornbills in northeast India
(12/16/2013) Hornbills are as peculiar, as they are magnificent. Their calls especially, can sound rather strange to the uninitiated - some grunt, some growl, and some cackle maniacally. These queer birds, with their large brightly-colored curved beaks, and a distinctive cavity-nesting habit, are also totem animals for many tribes in India.
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.
Camera traps find less mammals than expected in Costa Rican corridor
(12/16/2013) A new study using camera traps in mongabay.com's open-access journal Tropical Conservation Science has surveyed the diversity of medium and large-sized predators in the San Juan-La Selva biological corridor in Costa Rica, whilst also demonstrating how alteration of habitat is affecting the use of this corridor.
Sonar directly impacts whale behavior, according to military study
(12/13/2013) Noises from pile-driving, explosives, ship motors and other industrial activities have all been linked to adverse effects on marine wildlife. A new study, funded by the US Navy and published in Proceedings of the Royal Society B, suggests that military sonar may be directly impacting whale behavior. The idea that sonar might affect the behavior of whales is not new. A number of reports in the past have linked the use of military sonar to mass stranding events of beaked whales and baleen whale species.
Reforestation can't offset massive fossil fuels emissions
(12/13/2013) With the Australian, Japanese, and Canadian governments making an about-face on carbon-emissions reduction targets during the Warsaw climate summit, some experts are warning that the global need for solutions offsetting CO2 emissions is passing a "red line." Land-based mitigation practices comprise one of the solutions on the table as a result of both the United Nations Framework Convention on Climate Change (UFCCC) and the Kyoto Protocol; however, a paper published in Nature Climate Change by an international team led by Brendan Mackey, has raised the looming question of whether or not land-based practices can actually improve CO2 levels as much as hoped.
Bonobos: the Congo Basin's great gardeners
(12/11/2013) The survival of primary forests depends on many overlapping interactions. Among these interactions include tropical gardeners, like the bonobo (Pan pansicus) in the Congo Basin, according to a new study in the Journal of Tropical Ecology. Bonobos are known as a keystone species, vital to the diversification and existence of their forests.
Journalists win environmental news reporting prizes
(12/10/2013) Mongabay's internship program has benefited from the hard work and great environmental reporting of more than 30 writing interns since the program's inception in July 2012. This year, Mongabay asked this pool of contributing authors to submit their most compelling piece out of over 150 articles. The submissions were then reviewed by a panel.
Sri Lankan elephant amnesty will lead to poaching, warn conservationists
(12/03/2013) Environmentalists have responded with alarm to a proposed amnesty permitting the registration of illegally captured elephants in Sri Lanka. Recent reports in Sri Lankan media have outlined the proposal, stating that during the amnesty period it would be possible to register elephant calves for a fee of about $7,600. Elephants are closely linked with Sri Lankan history and culture, and are considered sacred in both Buddhism and Hinduism. But the situation for elephants in the country is complicated.
Where have all the dugongs gone?
(12/03/2013) Legend has it that lonely sailors mistook them for beautiful, mythical mermaids. But as it turns out, the muse behind these beguiling sea nymphs was instead the dugong – a rather ungainly, gentle and mini-bus sized marine mammal, cousin to the manatees and part of the sea cow family. However, while they may have once fuelled stories for fairytales and Disney movies, their far-from-glamorous life is currently under serious threat in many parts of the world.
Not all mangroves are created equal: new map reveals carbon storage hot-spots
(11/26/2013) Mangrove forests are one of the most important weapons in the fight against climate change. Not only do they directly store huge amounts of carbon, but they actively capture additional carbon dioxide from the atmosphere and sequester it in their soils. When mangroves are destroyed, huge quantities of carbon are released into the atmosphere, significantly contributing to greenhouse gas emissions.
Consumer report uncovers why people buy rhino horn
(11/26/2013) The rhinoceros is one of the largest and most iconic animals to roam the earth. However, poaching for their horn, erroneously believed to have medicinal value, has led the IUCN Red List to classify three of the world's five species as Critically Endangered. But, a new consumer report by the wildlife trade monitoring network, TRAFFIC, finds that rhino horn consumers in Vietnam buy the illegal product as much to raise their social status as to attempt to treat a fever or hangover.
Satellites reveal browning mountain forests
(11/22/2013) In a dramatic response to global warming, tropical forests in the high elevation areas of five continents have been "browning" since the 1990s. They have been steadily losing foliage, and showing less photosynthetic activity. Scientists analyzed the forest cover by using satellites to measure sunlight bouncing off the surface of the earth, then determining the different surface types via reflection patterns.
Canopy crusade: world's highest network of camera traps keeps an eye on animals impacted by gas project
(11/21/2013) Oil, gas, timber, gold: the Amazon rainforest is rich in resources, and their exploitation is booming. As resource extraction increases, so does the development of access roads and pipelines. These carve their way through previously intact forest, thereby interrupting the myriad pathways of the species that live there. For species that depend on the rainforest canopy, this can be particularly problematic.
The quicksilver demon: rogue gold-mining is the world's largest source of mercury pollution
(11/20/2013) In 1956, in the quiet seaside town of Minamata on the southwestern coast of Japan's Kyushu Island, cats began to behave very strangely. They convulsed, displayed excessive salivation, and gradually lost the ability to walk. Then, dead birds began to fall out of the sky. Shellfish opened and decomposed. Fish also displayed abnormal behaviors, eventually floating up to the surface of the Shiranui Sea. Many of the ailing cats wandered into the sea and drowned. Soon, there were no more cats alive in the area.
The swan song of India's dancing bears
(11/20/2013) India’s last dancing bear has retired. As the stars of their cruel little roadshows, sloth bears danced to the piercing sounds of the damru for hundreds of years. Orphaned by poachers and trained by the Qalandars, a nomadic Muslim community, these bears trudged through towns and villages to earn their masters a meager livelihood.
Nearly half a million seabirds die in gillnets every year, but solutions exist
(11/18/2013) A recent study from the Biological Conservation journal brings shocking news: every year across the globe, an estimated 400,000 seabirds are killed by gillnets. Gillnets, a common term for any net used to entangle and catch fish, are used all over the world, and at any depth. These nets, whether used in subsistence or commercial fishing, trap anything that swims through them. When unintended marine wildlife, or "bycatch," is caught in these nets, the results can be significant.
New bat species discovered in Brazil leaves another at risk
(11/15/2013) A team of researchers has discovered a new species of bat in Brazil, which has put a previously known species, Bokermann's nectar bat (Lonchophylla bokermanni), at risk of extinction. Long thought to comprise one species, the bat populations of the Atlantic Forest and the Cerrado – the tropical savannah of Brazil's interior - are in fact distinct from one another, according to a new study in Zootaxa. Scientists now say the Atlantic Forest's population represents a newly described species, which they have dubbed Peracchi's nectar bat (Lonchophylla peracchii).
Newly discovered beetles construct private homes out of leaf holes and feces
(11/12/2013) Scientists have discovered two new species of leaf beetles in southern India that display a novel way of using leaf holes and their fecal pellets to build shelters – a nesting behavior previously not known among leaf beetles. Discovered in the forests of the Western Ghats in the states of Karnataka and Kerala, the scientists have named these pin-head sized leaf beetles Orthaltica syzygium and Orthaltica terminalia, after the plants they feed on: Syzygium species (e.g., the Java plum) and Terminalia species (e.g., the flowering murdah).
Five new, cryptic bats discovered in Senegal
(11/11/2013) An international research team led by Daurina Koubinova has discovered five new species of vesper bats during a series of expeditions to Senegal's Niokolo-Koba National Park. The new species are considered cryptic, because their genetic makeup is different despite physical similarities. The new bats have yet to be named.
Ultraviolet nets significantly reduce sea turtle bycatch
(11/11/2013) Bycatch, a side-effect of commercial fishing in which non-target species are accidentally caught, is linked to severe population declines in several species. Sea turtles are particularly impacted by small-scale coastal gillnetting practices, in which large nets are deployed and indiscriminately snag anything of a certain size that attempts to swim through them. However, that may soon change.
Seahorses on your iPad: new app allows anyone to track and document seahorses
(11/08/2013) Annually, approximately 13 million seahorses—live and dead—are traded around the globe. At this scale, the seahorse trade is potentially very destructive to a group of animals comprised of 48 species, 11 of which are listed by the International Union for Conservation and Nature (IUCN) as threatened with extinction.
Dolphins, bats and the evolution of echolocation
(11/08/2013) A dolphin swimming through the world’s oceans after fish, and a bat flying through the air with its membranous wings to catch insects or eat fruit: at first glance, it looks like no two creatures could be more different. But it turns out they share a superpower - they hunt prey by emitting high-pitched sounds and listening for a returning echo. A recent study published in the journal Nature Letters has shown that the regions of the genome responsible for this ability are strikingly similar between these very different mammals.
Critically Endangered Jamaican iguana imperiled by port development
(11/08/2013) The story of the Jamaican iguana (Cyclura collie) is one of adversity and resurgence. Once believed extinct, the species has made a remarkable comeback over the last two decades. However, according to concerned scientists, a new plan to build a massive port in the iguana's habitat could push the species back to the edge of extinction.
Beetles in the spotlight: a new species of burying beetle from the Solomon Islands Archipelago
(11/07/2013) If you thought of the little beetle that you saw the other day as just a ‘regular one’ then this might interest you. Scientists from the University of Alaska discovered Nicrophorus efferens, a new species of burying beetle from Solomon Islands. Studying six adult specimens borrowed from the Bernice Pauahi Bishop Museum of Hawaii (BPBM), Dr Sikes and Tonya Mousseau describe the new species in a detailed taxonomic assessment published in the journal Zookeys, and how it differs from two closely related species of the Solomon Islands.
Like humans, marmosets are polite communicators
(11/06/2013) Common marmoset monkeys have been described as having human-like conversations according to a team of researchers from the Princeton Neuroscience Institute. Native to Brazil, marmosets are highly social animals, using simple vocalizations in a multitude of situations: during courtship, keeping groups together and defending themselves. They also, according to the study published in Current Biology, exchange cooperative conversations with anyone and everyone - not just with their mates.
Scientists: to save the Malayan tiger, save its prey
(10/31/2013) A major premise of biology, as any high-schooler can tell you, is the study of the connections between organisms. Perhaps nowhere is there a better example of this than in Malaysia, where the population of Endangered Malayan tigers (Panthera tigris jacksoni) is being undercut by dwindling prey. A recent study by MYCAT, the Malaysian Conservation Alliance for Tigers, highlights this connection by presenting a distinct correlation between prey and tiger population.
New species of beetle discovered in megacity
(10/30/2013) When imagining the discovery of a new species, most people conjure thoughts of intrepid explorers, battling the odds in remote rainforests. But this needn't be the case, at least according to a new study published in Zookeys. The study reports the discovery of a new species of water beetle in the heart of the 10th largest megacity in the world: Manila, Philippines.
The mystery of the disappearing elephant tusk
(10/30/2013) Give it a few thousand years, and tusks could completely disappear from the Asian elephant (Elephas maximus). The beautifully smooth, elongated ivory incisors neatly bordering a long trunk are iconic in the public mind. The reigning hypothesis is that tusks evolved to help male elephants fight one another, as demonstrated when males compete over females in estrus. However, a recent study published in the journal Animal Behaviour has shown that tusks may not be key factors in tussles, at least as far as elephants are concerned.
Small invertebrates could be key to uncovering the mysteries of killer amphibian fungus
(10/22/2013) In 2004, the first-ever Global Amphibian Assessment (GAA) reviewed all 5,743 amphibian species known to science and concluded that 32% were threatened with extinction - a number far exceeding corresponding figures for birds and mammals (12 to 23% respectively). In addition to the usual culprits of climate change and habitat destruction, a startling 92.5% of amphibians listed as Critically Endangered were found to be undergoing enigmatic declines linked to an unexpected perpetrator - the chytrid fungus, Batrachochytrium dendrobatidis (Bd).
98% of marine fish headed for the aquarium trade die within a year in the Philippines
(10/22/2013) Almost all wild caught marine fish for the aquarium trade will die within a year of capture, according to WWF. Following months of interviews with Filipino marine exporters and hobbyists, WWF-Philippines have found that roughly 80% of all marine fish die before they are sold, and those that survive long enough to be bought by hobbyists are extremely likely to be dead in under a year.
Mammal-watching: one man's obsession to see the world's mammals
(10/16/2013) There are more than 5,000 different mammal species across the globe, but with this number being dwarfed by the 10,000 bird species, it is little wonder that bird-watching has become the most common wildlife watching hobby in the world. While there are thousands of websites dedicated to ornithology enthusiasts, with information detailing the best places to see particular species and how to find them, similar resources about mammals remain scarce.
Sea and storm: coastal habitats offer strongest defense
(10/11/2013) Surging storms and rising seas threaten millions of U.S. residents and billions of dollars in property along coastlines. The nation's strongest defense, according to a new study by scientists with the Natural Capital Project at the Stanford Woods Institute for the Environment, comes from natural coastal habitats.
Recovering forests 'heal' themselves by speeding up nitrogen fixation
(10/08/2013) Nitrogen is colorless, odorless and tasteless, but all life on earth depends on it. Without it, our bodies cannot synthesize the nucleic acids that make up our DNA, or the protein-forming amino acids that are the very building blocks of our cells. Problematically, atmospheric nitrogen is relatively inert or nonreactive. This has created a unique biological dependency on a process called nitrogen fixation—where inert nitrogen from the atmosphere is converted into more reactive ammonia, a major component of soil fertilizers.
No place like home: scientists discover that male crested penguins head home earlier than females
(10/08/2013) Male crested penguins are hard workers - especially when it comes to their elaborate breeding ritual. After gathering in massive colonies to mate, they find and establish a nesting site, help incubate the eggs females lay, and then guard the chicks after they hatch. Male crested penguins have also been known to arrive at their breeding locations long before the females. But the reasons for this have been largely speculative. Do the males start swimming back to their breeding grounds earlier than the females?
Myanmar faces new conservation challenges as it opens up to the world
(10/04/2013) For decades, one of Southeast Asia's largest countries has also been its most mysterious. Now, emerging from years of political and economic isolation, its shift towards democracy means that Myanmar is opening up to the rest of the world. Myanmar forms part of the Indo-Burma biodiversity hotspot, and some of the largest tracts of intact habitat in the hotspot can be found here.
Amphibians evolve resistance to popular pesticide
(10/04/2013) Rachel Carson and, more recently, Sandra Steingraber have successfully drawn popular attention to the risks of pesticides on wildlife. Many of the environmental consequences of pesticides have now been well documented by scientists; however, studies investigating the evolutionary consequences of pesticides on non-target species are largely missing. Not surprisingly, most studies looking at how species evolve in response to pesticide-use have been on target species such as mosquitoes and crop pests, which show that some target species have evolved resistance to common pesticides.
Climate change could increase diarrheal disease in Botswana
(10/03/2013) Climate change may increase the incidence of diarrheal disease in Botswana, according to a recent study in the International Journal of Environmental Research and Public Health. "Diarrheal disease is a very important public health problem in Botswana," said lead author Kathleen Alexander, who led a unique 30-year analysis (1974-2003) on the incidence of diarrhea in Botswana. "As a water-restricted country, Botswana is predicted to be heavily impacted by climate change.
Pet fish invade ecosystem, upending nutrients and impoverishing fishers
(10/02/2013) If you, or someone you know, owns a freshwater aquarium, chances are you have seen the peculiar little creature attached face-first to the glass in effort to find a morsel of algae. This algae eater, popularly known as the sucker fish, is the sailfin catfish, or plecos. It is one of the most commonly purchased fish in the freshwater aquarium fish trade, and, according to recent research in The Royal Society B, aquarists often reintroduce the sucker-fish into the wild with detrimental consequences.
Wildlife in Nilgiris Biosphere Reserve suffers from lack of a transition zone
(10/01/2013) The Nilgiris Biosphere Reserve in southern India acts as a conduit between the biodiversity-rich Western Ghats, a mountain range parallel to the western coast of India and its eastern counterpart, the Eastern Ghats. Established in 1986 by Government of India, the 5,520 square kilometer reserve was recognized by UNESCO in 2000. However a new study in mongabay.com's open-access journal Tropical Conservation Science finds that the lack of a transition zone in the Nilgiris Biosphere Reserve has undercut the aims of this crucial protected area.
African manatee hanging on in Cameroon
(09/30/2013) In the Lower Basin of the Sanaga River in Cameroon, near Lake Ossa and the Douala-Edea National Parks, manatees swim and float about like round, potato-shaped mermaids. This region is home to the West African manatee (Trichechus senegalensis), an aquatic mammal facing a decline in population. Classed as Vulnerable by the IUCN Red List, the West African manatee is threatened by excessive kills, habitat loss, and habitat degradation. Given this, and the dearth of information about manatees, a group of Cameroon scientists have taken an ethnobiological approach (i.e. the interaction between people and wildlife) by employing skilled, knowledgable locals to collect data on the manatees.
Camera-traps reveal surprising mammals at remote site in Honduras (photos)
(09/30/2013) A camera trap survey along the Sikre River in Honduras has discovered that the region is home to a menagerie of rare mammals, including giant anteaters. The survey, published in mongabay.com's open access journal, Tropical Conservation Science, recorded five cat species in 70 square kilometers.
New prioritization for Brazil's threatened mammals pushes little known primates and rodents to the top
(09/30/2013) Scientists have applied a species prioritization scheme to Brazil's diverse mammals to deduce which species should become the focus of conservation efforts over the next few years in a new paper published in mongabay.com's open-access journal Tropical Conservation Science.
Climate change pushing tropical trees upslope 'exactly as predicted'
(09/27/2013) Tropical tree communities are moving up mountainsides to cooler habitats as temperatures rise, a new study in Global Change Biology has found. By examining the tree species present in ten one-hectare plots at various intervals over a decade, researchers found that the proportion of lowland species increased in the plots at higher elevations. The study, which was undertaken in Volcan Barva, Costa Rica, adds to a growing body of evidence that climate change is having an impact on species range distributions.
Newly discovered chytrid fungus devastates salamander populations
(09/19/2013) A frightening disease has been ravaging amphibians across the planet. At least 350 species have been infected, two hundred of which have suffered massive population reductions or extinctions, some even occurring within the space of weeks. In 1999, a single fungal species called Batrachochytrium dendrobatidis (Bd), commonly known as the chytrid fungus, was identified as the causative agent for these rapid die-offs.
India moves rapidly to protect Amur falcons from mass-hunting
(09/13/2013) In October last year, an astounding mass hunting came to light—an estimated 120,000–140,000 Amur falcons were being hunted and killed in Nagaland, India, every year. A small bird of prey, the Amur falcon (Falco amurensis) records one of the longest migrations among all birds—a staggering 22,000 km annually. Their journey starts in China and Siberia where they breed and spend their summers.
Bornean orangutans travel along the ground
(09/12/2013) A recent study of forest in East Kalimantan, Borneo has found that orangutans travel on the ground far more often than expected. The study, published in the American Journal of Primatology, was carried out in Wehea Forest involving the use of 78 camera traps across 38 square kilometres of forest.
600 vultures killed by elephant poachers in Namibia
(09/11/2013) As the illegal poaching of African elephants and rhinos reaches epidemic levels, other species are also suffering catastrophic losses as a direct result of poachers' behavior. A recent incident in July, where a poisoned elephant carcass led to the death of 600 vultures near Namibia's Bwabwata National Park, has highlighted how poachers' use of poison is now one of the primary threats to vulture populations.
