Often overlooked, small wild cats are important and in trouble
(08/05/2008) While often over-shadowed by their larger and better-known relatives like lions, tigers, leopards, and jaguars, small cats are important indicators of the health of an ecosystem, says a leading small cat expert who uses camera traps extensively to document and monitor mammals in the wild. Dr Jim Sanderson, a scientist with the Small Cat Conservation Alliance and Conservation International, is working to save some of the world's rarest cats, including the Andean cat and Guigna of South America and the bay, flat-headed, and marbled cats of Southeast Asia. In the process Sanderson has captured on film some of the planet's least seen animals, including some species that have never before been photographed. He has also found that despite widespread criticism, some corporate entities are effectively protecting remote wilderness areas.
Corporations become prime driver of deforestation, providing clear target for environmentalists
(08/05/2008) The major drivers of tropical deforestation have changed in recent decades. According to a forthcoming article, deforestation has shifted from poverty-driven subsistence farming to major corporations razing forests for large-scale projects in mining, logging, oil and gas development, and agriculture. While this change makes many scientists and conservationists uneasy, it may allow for more effective action against deforestation. Rhett A. Butler of Mongabay.com, a leading environmental science website focusing on tropical forests, and William F. Laurance of the Smithsonian Tropical Research Institute in Panama believe that the shift to deforestation by large corporations gives environmentalists and concerned governments a clear, identifiable target that may prove more responsive to environmental concerns.
Developing the world's most sophisticated program for mapping endangered species
(08/04/2008) It was big news in April when a comprehensive map of Madagascar's rich and unique biodiversity was unveiled. The project managed to map ranges of 2,315 species across an island larger than France. Such detailed mapping could not have happened without the aid of Steve Phillips. A researcher at AT&T, Phillips developed the software that made such detailed and expansive mapping possible.
New Costa Rica guide offers insight on responsible tourism
(08/04/2008) Costa Rica is the world's most popular destination for rainforest tourism thanks to its spectacular biodiversity, relative ease-of-access and safety, and many natural attractions. In 2007 nearly 2 million tourists visited the country, generating almost 2 billion in revenue -- more than the combined income from bananas and coffee.
Scientists discover world's smallest snake species
(08/03/2008) If one wanted to overcome their fear of snakes, they may want to start with the newly discovered Leptotyphlops carlae. Measuring less than four inches long, even stretched out this new species of threadsnake can't compete with the average pen or pencil.
Brazil asks rich countries to fund Amazon conservation
(08/02/2008) Brazilian President Luis Inacio Lula da Silva officially unveiled plans to raise a $21 billion fund for protecting the Amazon rainforest. The plan, which was originally announced several months ago, aims to be funded by foreign donations. Contributors will not be eligible for carbon credits that may be generated by reductions in deforestation.

This is a look at past, current and potential future drivers of deforestation in the Brazilian Amazon.
Rock star or marine biologist? Hans Walters chose both
(07/31/2008) There aren't many who swim with sharks by day and rock out on a stage at night, but Hans Walters does just that! A man with two distinctly different passions, music and marine biology, Walters is a supervisor for the animals at the New York Aquarium, and then after hours, grabs a microphone as lead singer (playing just enough guitar to be dangerous) for the New York-based hard rock band, 61/49.
Ontario to preserve area of forest the size of Uganda
(07/31/2008) The government of Ontario has announced it will preserve 56 million acres of boreal forest from all types of development. The reasons for such a large conservation plan are numerous: preservation of the forest will benefit the world as a massive carbon storehouse; the area is a major source of freshwater; and home to over 200 species, many of which are threatened, such as polar bears, wolverines, and caribou. The area will be open to eco-tourism, but will be closed to mining, logging, and gas exploration.
U.N. raises thermostats to cut emissions, save money

Logging company Danzer accused of tax fraud in the Congo
(07/31/2008) A major European logging company is using an elaborate profit-laundering system to smuggle timber revenue out of Africa and avoid paying taxes to the governments of the Democratic Republic of Congo (DRC) and the Republic of the Congo, alleges a new report published by Greenpeace.
Cane toads are killing crocodiles in Australia
(07/30/2008) The cane toad has been a scourge to Australian wildlife for decades. An invasive species, the cane toad competes with local endemic frog species and due to its high toxicity kills any predator who preys on it, including snakes, raptors, lizards, and the carnivorous marsupial, northern quoll. New research has uncovered another victim of the toad. The freshwater crocodile has suffered massive population declines due to consuming the irascible toad.
Conservation groups could augment poverty alleviation in some remote areas
(07/30/2008) Conservation groups are well-positioned to assist in poverty alleviation efforts in some of the world's poorest and most remote places where they have otherwise been neglected by governments and aid organizations, argues a report published in the journal Oryx.
Ocean acidification may hurt reproduction in marine life

Adaptation to climate change will be difficult for Madagascar
(07/29/2008) Madagascar's high levels of endemism coupled with its extensive loss and degradation of ecosystems leave its species particularly vulnerable to climate change. A new paper evaluates these risks and sets forth conservation priorities to best maintain the ecological resilience of the island nation.
Island biogeography theory doesn't explain biodiversity changes in forest fragments
(07/28/2008) Island biogeography theory, the idea that fragmented ecosystems have lower species richness per unit of area compared with contiguous habitats, has served as a useful conceptual model to understand the effects of habitat fragmentation but fails to explain the complexities of change in isolated forest fragments, according to a synthesis published last month in the journal Biological Conservation.
An interview a shaman in the Amazon rainforest
(07/28/2008) Deep in the Suriname rainforest, an innovative conservation group is working with indigenous tribes to protect their forest home and culture using traditional knowledge combined with cutting-edge technology. The Amazon Conservation Team (ACT) is partnering with the Trio, an Amerindian group that lives in the remote Suriname-Brazil border area of South America, to develop programs to protect their forest home from illegal gold miners and encroachment, improve village health, and strengthen cultural ties between indigenous youths and elders at a time when such cultures are disappearing even faster than rainforests. In June 2008 mongabay.com visited the community of Kwamalasamutu in Suriname to see ACT's programs in action. During the visit, Amasina, a Trio shaman who works with ACT, answered some questions about his role as a traditional healer in the village.
Newly discovered monkey is critically endangered by logging, poaching
(07/28/2008) A newly discovered species of monkey may already be threatened with extinction, according to a study published in the journal Oryx.
Climate change will increase the erosion of coral reefs
(07/28/2008) Coral reefs are particularly susceptible to climate change. Warming waters have been shown to bleach coral, killing off symbiotic algae that provide them with sustenance, and often leading to the death of the coral itself. Much attention has been placed on bleaching coral, but now scientists have discovered an additional danger to coral reefs in a warming world: erosion.
Unlike humans, tree shrews don't get drunk
(07/28/2008) The pentailed treeshrew, sporting a mouse-like body and feathery tail, seems an unlikely drinker. Yet, new research shows that this one-and-half ounce creature's main food source, the nectar of the bertam palm, is highly fermented. The nectar can contain a peak alcohol concentration of 3.8 percent. This is a little less than a Bud Light.
The end of migrations: wildlife's greatest spectacle is critically endangered
(07/28/2008) If we could turn back the clock about 200 years, one could watch as millions of whales swam along their migration routes. Around 150 years ago, one could witness bison filling the vast America prairie or a billion passenger pigeons blotting out the sky for days. Only a few decades back and a million saiga antelope could be seen crossing the plains of Asia.
Monster manta ray species discovered
(07/25/2008) Researchers have discovered a previously unknown species of manta ray. Previously there was believed to be only a single species of ray but genetic analysis now shows there are at least two, and possibly three, species.

(07/24/2008) Industrialized nations could collectively offset 500 million tons carbon of dioxide emissions at roughly $2 per ton by protecting tropical rainforests, according to estimates published in the online edition of Proceedings of the National Academy of Sciences.
New plan would pay tropical countries for saving forests, regardless of level of threat
(07/24/2008) Deforestation and forest degradation account for around a fifth of global carbon emissions from human activities, but new policy measures are focusing reducing such emissions as a cost-effective way to fight global warming. While the concept — known as REDD for "Reducing Emissions from Deforestation and Degradation" — has found wide support from politicians, scientists, and environmentalists, there are lingering concerns over how to compensate countries that have extensive forest cover and low rates of annual forest loss, since payments are based on historical deforestation rates. A new proposal seeks to get around this issue by factoring in all the terrestrial carbon in a tropical landscape — regardless of level of threat it faces — and packaging it as a tradable commodity.
Brazil to send more police into the Amazon to fight illegal logging
(07/23/2008) Brazilian President Luiz Inacio Lula da Silva signed two decrees Tuesday to rein in illegal forest clearing in the Amazon, reports the Associated Press (AP).

Secret power plan would devastate Sarawak's rainforest with 12 new hydropower plants
(07/23/2008) Environmentalists have called on the Malaysian government to develop a comprehensive energy policy, following the discovery of secret plans to build a network of power plants across interior Sarawak on the island of Borneo.
Leaf-cutter ants test theories about the Amazon's biodiversity
(07/23/2008) No one knows for certain how many insect species reside in the Amazon. One oft-quoted estimate is 30 million, but the actual number could be significantly lower or higher than this. Either way, biologists have long wondered why the richness of insect diversity in the Americas' tropical forests is exponentially higher than temperate forests. Three popular hypotheses have emerged—the theory of refugia, the marine incursion hypothesis, and the riverine barrier hypothesis. To test these theories a group of scientists, headed by Dr. Scott Solomon, studied three species of leaf-cutter ant species from the Amazon.
How to replant a mangrove forest: local, low-cost initiatives prove most successful
(07/23/2008) Mangrove replanting and rehabilitation has become a widespread and important environmental initiative worldwide. Mangrove forests play key ecological roles, including sustaining fish populations and other wildlife, preventing erosion along coastlines, and acting as an overall carbon sink. Furthermore, mangroves have received attention lately for their role in providing an effective buffer against typhoons. In light of the many replanting initiatives now occurring, researchers J.H. Primavera and J.M.A. Esteban conducted a study of the overall effectiveness of different mangrove rehabilitation schemes. Their findings show that small, local, and generally cheaper initiatives have a higher success rate over large costly government and international programs.
Biofuels can reduce emissions, but not when grown in place of rainforests
(07/22/2008) Biofuels meant to help alleviate greenhouse gas emissions may be in fact contributing to climate change when grown on converted tropical forest lands, warns a comprehensive study published earlier this month in the journal Environmental Research Letters. Analyzing the carbon debt for biofuel crops grown in ecosystems around the world, Holly Gibbs and colleagues report that "while expansion of biofuels into productive tropical ecosystems will always lead to net carbon emissions for decades to centuries... [expansion] into degraded or already cultivated land will provide almost immediate carbon savings." The results suggest that under the right conditions, biofuels could be part of the effort to reduce humanity's carbon footprint.
Population of critically endangered lemurs discovered in Madagascar
(07/22/2008) Scientists in Madagascar have discovered a population of greater bamboo lemurs (Prolemur simus), a critically endangered species of primate, in an area more than 400 kilometers away from its only known refuge, reports conservation International.
Half of the Philippines' endemic wildlife is with extinction
(07/22/2008) More than half the birds, amphibians and mammals endemic to the Philippines are threatened with extinction, according to a statement released by the country's environment and natural resources department and reported by AFP.
Coral susceptibility to bleaching due to small differences in symbiotic relationship
(07/22/2008) Coral reefs are now considered the second most threatened group of animals in the world, with nearly one-third of corals listed as endangered (amphibians retain the dubious honor of being number one). Although corals face many threats, the greatest is bleaching caused by warming oceans due to climate change. However, some coral populations are more susceptible to bleaching than others, even including corals of the same species. New research has uncovered that the reason lies in small differences in the symbiotic relationship between corals and their symbionts, small marine animals and protozoa. Such differences, however minuscule, have a huge impact on the likelihood of a coral's ability to survive warming oceans.
Shell Oil funds "open source" geoengineering project to fight global warming
(07/21/2008) Shell Oil is funding a project that seeks to test the potential of adding lime to seawater as a cost-effective way to fight global warming by sequestering large amounts of carbon dioxide in the world's oceans, reports Chemistry & Industry magazine.
600 species of mushrooms discovered in Guyana
(07/21/2008) In six plots of Guyanese rainforest, measuring only a hundred square meters each, scientists have discovered an astounding 1200 species of macrofungi, commonly known as mushrooms. Even more surprising: they believe over 600 of these are new to science — that's equivalent to a new species every square meter.
Mangroves are key to healthy fisheries, finds study
(07/21/2008) Mangroves serve as a critical nursery for young marine life and therefore play an important role in the health of fisheries and the economic well-being of fishermen, report researchers writing in the early online edition of the Proceedings of the National Academy of Sciences.
