Arachnopocalypse: with birds away, the spiders play in Guam
(09/17/2012) The island of Guam is drowning in spiders. New research in the open-access journal PLOS ONE has found that in the wet season, Guam's arachnid population booms to around 40 times higher than adjacent islands. Scientists say this is because Guam, a U.S. territory in the Pacific, has lost its insect-eating forest birds. Guam's forests were once rich in birdlife until the invasion of non-native brown tree snake (Boiga irregularis) in the 1940s decimated biodiverse bird communities. Now, the island is not only overrun with snakes, but spiders too.
Urban sprawl could doom some biodiversity hotspots by 2030
(09/17/2012) Projected urban expansion could consume hundreds of thousands of hectares' worth of key biodiversity hotspots over the next twenty years, triggering the release of some 5 billion tons of carbon dioxide from direct land use change and further endangering hundreds of species, warns a new study published in the journal Proceedings of the National Academy of Sciences.
Turtle knowledge in Africa shows significant gaps
(09/17/2012) Sometimes turtles fall through the cracks: a new study in the open access journal Tropical Conservation Science, has uncovered a number of 'gap species' in the turtle families inhabiting Africa. 'Gap species' are those that are recorded in one country or another, but not in adjacent countries which could be due to a lack of data, a change in ecosystems, or human impacts.
Bushmeat consumption differs between communities in Tanzania
(09/17/2012) Bushmeat consumption depends on the make-up of individual communities, according to a new study in the open access journal Tropical Conservation Science. By interviewing indigenous groups and refugees living near two protected areas in western Tanzania, researchers found that consumption rates differed significantly, likely based on costliness and access.
Wax palm can be sustainably harvested
(09/17/2012) The wax palm can be harvested sustainably with just a few management restrictions, according to a new study in mongabay.com's open access journal Tropical Conservation Science (TCS). Found only in the Peruvian and Ecuadorian Andes, the leaves of the wax palm (Ceroxylon echinulatum) are used to make Easter handicrafts. But the practice has caused fears that the species, which is currently categorized as Vulnerable by the IUCN Red List, is being overexploited.
Rare birds abound in Brazil's Acre state
(09/17/2012) The Brazilian state of Acre has had little attention by bird-lovers and bird scientists, though it lies deep in the Amazonian rainforest. Now a new survey in mongabay.com's open access journal Tropical Conservation Science by ornithologist, John J. DeLuca, works to build a better picture of rare birds in this largely-neglected region. The work is all the more important as the Brazil-Peru Interoceanic Highway could bring massive changes to the region.
Buffer zones key to survival of maned wolf
(09/17/2012) Known for its abnormally long lanky legs, its reddish-orange coat, and its omnivorous diet, the maned wolf (Chrysocyon brachyurus) is one of the more beautiful and bizarre predators of South America. However its stronghold, the Brazilian Cerrado, is vanishing rapidly to industrialized agriculture and urban development. Now, a new study in mongabay.com's open access journal Tropical Conservation Science reveals the key role of buffer zones and unprotected areas in keeping the maned wolf from extinction in the Cerrado savannah, where only 2 percent of the ecosystem is under protection.
Local knowledge matches scientific data on wildlife abundances
(09/17/2012) How far can scientists trust local knowledge when it comes to ecosystems? This is a question that is undergoing heavy debate in scientific circles. A new study in mongabay.com's open access journal Tropical Conservation Science contributes to the debate by finding that basic local knowledge of animal abundance in Gonarezhou National Park, Zimbabwe aligned closely with scientific surveys.
Rodents have lowest diversity in primary forests in the Congo
(09/17/2012) For many animal families, diversity and abundance rises as one moves away from human-impacted landscapes, like agricultural areas, into untouched places, such as primary rainforests. However, a new study in mongabay.com's open access journal Tropical Conservation Science, shows that the inverse can also be true. In this case, scientists working in the Democratic Republic of Congo's (DRC) Maskao Forest found that both rodent diversity and abundance was lowest in primary forest.
Extremely rare plant region left unprotected in the Yucatan Peninsula
(09/17/2012) For the first time, scientists have identified the areas of the Yucatan Peninsula that hold the highest concentrations of endangered woody plants, which includes trees, shrubs, and lianas.

Environmental journalist investigating illegal logging murdered in Cambodia
(09/13/2012) Less than five months after high-profile forest activist, Chut Wutty, was killed in Cambodia, an environmental journalist, Hang Serei Oudom, has been found slain in the trunk of his car, possibly murdered with an ax, reports the AFP. Oudum, who worked at the local paper Vorakchun Khmer Daily, was known for writing stories on epidemic of illegal logging in Cambodia, often linking the crime to business people and politicians. The car and body were found in a cashew nut plantation in Ratanakiri province, an area rife with logging.
Bird diversity at risk if 'agroforests' replaced with farmland
(09/13/2012) Agroforests contain much higher levels of bird diversity than their open agricultural counterparts, according to new research from the University of Utah. If large forests and agroforests continue to be replaced by simple open farms, bird communities will become much less specialized and entire groups may become extinct. Important roles for birds, such as pollination, pest control or seed dispersal, may remain unfilled if ongoing trends toward open agriculture continues and biodiversity decreases.
E.U. may eliminate subsidies for crop-based biofuels
