12 new species of frogs discovered in India

(02/03/2009) A dozen previously unknown species of frogs have been discovered in the forests of Western Ghats according to a paper published in latest issue of Zoological Journal of Linnean Society, London. The 12 species have been identified following a revision of the Philautus genus and are the result of ten years of field study in Kerala, Tamil Nadu, Karnataka. Goa, Maharashtra, and part of Gujarat, in the Western Ghats. The Western Ghats are considered a global biodiversity hotspot for their species richness and the threats the mountain range faces.


Seeking out the world’s rarest and most endangered birds

(02/02/2009) For an evolutionary biologist there is no conservation group whose work is more exciting than EDGE, a program developed by the Zoological Society of London (ZSL). Unique in the conservation world, EDGE chooses the species to focus on based on a combination of their threat of extinction and evolutionary distinctness. Katrina Fellerman, an evolutionary biologist herself and the EDGE birds’ coordinator, describes the organization as one that focuses on species, which “to put it bluntly, if lost, there would be nothing like them left in the world today”. Explaining further Fellerman says “We use evolutionary distinctiveness (ED) as a species-specific measure of the relative evolutionary value of species - it is a way of apportioning conservation value according to a species’ phylogenetic position. Species with few or no close relatives on the ‘tree of life’ have the highest ED scores.”


Amazon scientists awarded 'Nobel Prize' of conservation

(02/01/2009) Thomas Lovejoy of the H. John Heinz III Center for Science, Economics and the Environment and William F. Laurance of the Smithsonian Tropical Research Institute (STRI) have been awarded one of ecology's most coveted prizes for their work to understand and conserve the Amazon rainforest. The €400,000 BBVA Foundation Frontiers of Knowledge Award in Ecology and Conservation Biology is given annually to "honor contributions which significantly advance the stock of knowledge in this area for reasons of their importance and originality."

(01/30/2009) A previously unknown species of babbler has been discovered in China's Guangxi province near the border with Vietnam, reports Birdlife International.


Camera trap photos reveal bushmeat hunting threat to jaguars in Ecuador

(01/27/2009) Jaguars are the largest cats of the Americas and third largest cats in the world. The primary rainforest in the Amazon region of Ecuador is among their last remaining strongholds. Jaguars are listed as “vulnerable” in Ecuador, and Santiago Espinosa, Wildlife Conservation Society (WCS) fellow, PhD candidate from University of Florida/Gainesville, and WWF fellow, wants to know just how many jaguars are left in his home country. He is developing strategies to protect them by determining their numbers and the factors that threaten them through a unique method of non-invasive photography.


Global warming may doom emperor penguins to extinction

(01/27/2009) Disappearing sea ice around Antarctica may put emperor penguins at risk of extinction within the next century, warn scientists writing in this week's Proceedings of the National Academy of Sciences.


How to make forest fragments more hospitable to wildlife

(01/27/2009) While deforestation garners more attention from environmentalists, fragmentation of forest habitats is of significant concern to ecologists. As forest is fragmented into islands by logging, roads, agriculture, and other disturbances, edge effects alter the structure, microclimate and species composition of the forest patches, usually reducing the overall number of species. Forest specialists are most likely to suffer, losing out to "weedier" generalists and species that can tolerate forest "edge" conditions. A new study, conducted in the Brazilian Amazon, takes a detailed look at the types of birds that are likely to persist, and even thrive, in forest fragments.


One billion frogs harvested as food per year

(01/21/2009) The consumption of up to one billion frogs per year to satisfy human appetite for frog flesh is adding to the litany of pressures on global amphibian populations, write researchers in the upcoming issue of Conservation Biology.


Nickle mine in Madagascar may threaten lemurs, undermine conservation efforts

(01/21/2009) One of the world's largest nickel mines will have adverse impacts on a threatened and biologically-rich forest in Madagascar, say conservationists. The $3.8 billion mining project, operated by Canada's Sherritt, will tear up 1,300 to 1,700 hectares of primary rainforest that houses nearly 1,400 species of flowering plants, 14 species of lemurs, and more than 100 types of frogs. Many of the species are endemic to the forest. While Sherritt says on its web site that is working to minimize its environmental impact, including moving endangered wildlife, replanting trees, and establishing buffer zones near protected areas, conservationists say that efforts are falling short.


Fish may help fight ocean acidification

(01/19/2009) Fish are a major source of calcium carbonate production in marine ecosystems, a finding that has implications for ocean acidification, report scientists writing in the journal Science.


Secondary forest should become new conservation initiative

(01/19/2009) “I want to convince you we need to go beyond primary forests to preserve biodiversity”, Robin Chazdon told an audience at the National Natural History Museum during a symposium on the tropics. Chazdon, a professor of ecology and evolutionary biology at the University of Connecticut, has been studying secondary growth forests for over eighteen years. Secondary forests are those forests in the process of regrowth after being used for agriculture or logging. In her study area of NE Costa Rica, many of these forests were converted to pastures in the 1970s and 1980s, but have since been abandoned. In her presentation Chazdon argued that to preserve biodiversity numerous types of human-impacted landscapes, such as secondary forest, require attention by the conservation community.


Rediscovery of the solenodon, a rare venomous mammal, in Haiti

(01/09/2009) In the journal Oryx researchers from EDGE, a program of the Zoological Society of London (ZSL), have announced the rediscovery of a small population of Hispaniolan solenodons in Haiti. At the same time scientists in the Dominican Republic have taken the first ever footage of this endangered mammal.


Bizarre chirruping Purple Frog captured on film for the first time

(01/07/2009) Discovered only in 2003, the unique purple frog has been captured on film for the first time in India’s Western Ghats. A team of biologists from the University of Delhi, led by Dr. Sathyabhama Das Biju, captured several seconds of film of the frog running swiftly while calling for a mate with a distinct squeak.


Newly discovered pink iguana sheds light on Galapagos evolution

(01/06/2009) A newly identified, but already endangered species of pink land iguana may provide evidence of the lizard's evolution on the Galápagos Islands, report researchers writing in the Proceedings of the National Academy of Sciences.


17 new reptile and amphibian species discovered in Tanzania

(01/04/2009) 17 previously unknown species of reptiles and amphibians have been discovered in the rainforests of eastern Tanzania, report Italian and Tanzanian scientists. Conducting surveys of the 'virtually unexplored' forests of the South Nguru Mountains between 2004 and 2006, Michele Menegon of the Natural Science Museum of Trento in Italy and colleagues recorded 92 species of 'herps', of which 17 had never before been documented. The new species — which include chameleons, tree frogs, and snakes, among others — are believed to be endemic to the region.


How to save the Amazon rainforest

(01/04/2009) Environmentalists have long voiced concern over the vanishing Amazon rainforest, but they haven't been particularly effective at slowing forest loss. In fact, despite the hundreds of millions of dollars in donor funds that have flowed into the region since 2000 and the establishment of more than 100 million hectares of protected areas since 2002, average annual deforestation rates have increased since the 1990s, peaking at 73,785 square kilometers (28,488 square miles) of forest loss between 2002 and 2004. With land prices fast appreciating, cattle ranching and industrial soy farms expanding, and billions of dollars' worth of new infrastructure projects in the works, development pressure on the Amazon is expected to accelerate. Given these trends, it is apparent that conservation efforts alone will not determine the fate of the Amazon or other rainforests. Some argue that market measures, which value forests for the ecosystem services they provide as well as reward developers for environmental performance, will be the key to saving the Amazon from large-scale destruction. In the end it may be the very markets currently driving deforestation that save forests.


Ocean acidification is killing the Great Barrier Reef

(01/01/2009) Since 1990 the growth of coral in Australia's Great Barrier Reef has slowed its lowest rate in at least 400 years as a result of warming waters and ocean acidification, report researchers writing in Science. The finding portends a bleak near-term future for the giant reef ecosystem as well as calcifying marine organisms around the world.


Did cheetah come from China?

(12/30/2008) The discovery of a fossilized big cat skull in northwestern China provides new evidence that cheetah originated in the Old World, rather than the Americas, report scientists writing in the journal Proceedings of the National Academy of Sciences.


Malaysia seeks to reverse collapse of tiger population due to poaching, logging, palm oil

(12/23/2008) A new law seeks to double Malaysia's tiger population to 1,000 by 2020, reports BBC News.


Photos: Google Earth used to find new species

(12/22/2008) Scientists have used Google Earth to find a previously unknown trove of biological diversity in Mozambique, reports the Royal Botanic Gardens in Kew. Scouring satellite images via Google Earth for potential conservation sites at elevations of 1600 meters or more, Julian Bayliss a locally-based conservationist, in 2005 spotted a 7,000-hectare tract of forest on Mount Mabu. The scientifically unexplored forest had previously only been known to villagers. Subsequent expeditions in October and November this year turned up hundreds of species of plants and animals, including some that are new to science.


Visiting New Mexico's Crane festival

(12/21/2008) It’s six in the morning; the Southwest sky is rich in hues of yellow and red, yet despite the warm colors the air is cold and brisk enough that my toes have begun to go numb. We have been waiting nearly a half-hour for the light and warmth of morning to wake-up thousands of cranes and tens of thousands of snow geese. But so far, despite the glimmer growing across the sky, there isn’t a bird in sight. Every winter cranes and snow geese migrate from Montana, Idaho, Canada, and Alaska to Bosque del Apache, a National Wildlife Refuge in Central New Mexico. For the past twenty-one years the refuge has celebrated the bird migration with a Festival of the Cranes. People travel from around the state (and country) to see the Southwest skies fill with birds. The festival lasts a week and includes educational stands, social gatherings, tours, hikes, and speakers on natural history and the environment. For this one week the small town of Socorro becomes overrun with birders, scientists, and tourists.


Green-blooded, blue-boned frog discovered in Cambodia

(12/18/2008) Researchers have discovered a previously unknown species of frog in Cambodia. The amphibian is unusual in that is has green blood and turquoise-colored bones, a result of its transparent skin and a pigment that may make the species unpalatable to predators, according to Fauna & Flora International (FFI).


Corn expansion is hurting ladybugs

(12/15/2008) Expansion of corn acreage to meet ethanol targets is reducing the ability of beneficial insects to control pests, a loss valued at $58 million in the four states studied (Michigan, Iowa, Minnesota and Wisconsin), report researchers writing in the journal Proceedings of the National Academy of Sciences.


Climate change, ocean acidification may doom jumbo squid

(12/15/2008) Ocean acidification — driven by rising carbon dioxide levels in the atmosphere — may hurt the Humboldt squid, report researchers writing in the journal Proceedings of the National Academy of Sciences.


Photos of new species discovered in the Greater Mekong

(12/15/2008) More than 1,000 previously unknown species have been discovered in the Greater Mekong, a region comprising Cambodia, Laos, Myanmar (Burma), Thailand, Vietnam and the Yunnan Province of China, in the past decade, according to a new report from WWF.


Neither slow nor stupid, manatees are killed by boats because they can't hear them

(12/12/2008) Last year 73 manatees were killed by boats in Florida, despite two decades of manatee-related protections. In fact, manatee deaths due to boat collisions have only increased since protections were implanted. A recent study at the Florida Atlantic University has finally revealed why boats are so dangerous to manatees: the manatee cannot run from what it does not hear.


Elephants die significantly earlier in zoos than in wild

(12/11/2008) A new study from Science provides disturbing evidence that one of the zoos’ most popular animals, the elephant, faces a far shorter lifespan in captivity than in the wild. The findings raise new ethical and scientific questions regarding the rightness of keeping elephants in captivity and the causes of their shorter life-spans.


Chad's elephant population falls by two-thirds in two years

(12/11/2008) Civil strife of Chad — a consequence of the calamity in Darfur — is taking a toll on the country's elephant population, reports the Wildlife Conservation Society (WCS) which has launched an emergency appeal for funds to support conservation efforts in the country.


Why do different species of bird lay different numbers of eggs?

(12/10/2008) Clutch size varies greatly between bird species. Researchers now have a better idea why. Analyzing data on clutch size, biology, and habitat for 5,290 species of birds, a team of biologists — Walter Jetz (UC San Diego), Cagan H. Sekercioglu (Stanford University), and Katrin Böhning-Gaese (Johannes Gutenberg-Universität) — developed a model to predict variations in the number of eggs a species lays. They found clutch sizes are consistently largest in cavity nesters and in species occupying seasonal environments. The findings add depth and complexity to previous research that has shown short-lived species — ones that face high predation or have low survival rates among offspring — tend to lay more eggs than longer-lived species, which invest more resources in raising their offspring.


What allows rainforests to grow so wildly?

(12/10/2008) Molybdenum, a rare trace element, is the secret to rainforests' lush growth, reports research published in the journal Nature Geoscience.


Tropical species face high extinction risk

(12/10/2008) Tropical plant species face an inherently high extinction risk due to small populations and restricted ranges relative to temperate species, reports research published in PLoS ONE. These traits leave them vulnerable to habitat disturbance and climate change.


Fear and conservation

(12/10/2008) How does fear shape the behavior and conservation of deer, moose and antelope, not to mention carnivores such as wolves, bears, and even tigers? What is the natural state of wildlife, and how do animals know or learn which species to ignore or fear? Should we reintroduce predators to former habitats, even though the prey animals may be unprepared for their return?


Wildlife banking gets a marketplace

(12/09/2008) Ecosystem Marketplace, a site that provides information on markets and payment schemes for ecosystem services, has launched what it is calling the "first information clearinghouse" for the species credit trading industry.


Salvage logging offers hope for forests, communities devastated by industrial logging

(12/04/2008) As currently practiced, logging is responsible for large-scale destruction of tropical forests. Logging roads cut deep into pristine rainforests, opening up once remote areas to colonization, subsistence and industrial agriculture, wildlife exploitation, and other forms of development. Timber extraction thins the canopy, damages undergrowth, and tears up soils, reducing biodiversity and leaving forests more vulnerable to fire. Even selective logging is damaging. Nevertheless demand for wood products continues to grow. China is expected to import more than 100 million cubic meters of industrial roundwood by 2010, much of which will go into finished products shipped off to Europe and the United States. As much as 60 percent of this is illicitly sourced. Meanwhile in Brazil domestic hunger for timber is fueling widespread illegal logging of the Amazon rainforest. Armed standoffs between environmental police and people employed by unlicensed operators are increasingly common. Tropical Salvage, a Portland, Oregon-based producer of wood products, is avoiding these issues altogether by taking a different approach to meet demand for products made from high-quality tropical hardwoods. The company salvages wood discarded from building sites, unearthed from mudslides and volcanic sites, and dredged from rivers in Indonesia and turns it into premium wood products. In the process, Tropical Salvage is putting formers loggers to work and supporting a conservation, education and reforestation project on Java.


TV footage leads to discovery of strange and rare monkey

(12/04/2008) After showing archival TV footage of a critically endangered species of primate to local villagers, conservationists have discovered a previously unknown population of the Tonkin snub-nosed monkey in a remote forested area of northern Vietnam. The find the offers new hope for the species, which is down to 200 individuals in two of Vietnam's northern-most provinces — Tuyen Quang and Ha Giang.


Degraded grasslands better option for palm oil production relative to rainforests, finds study

(12/03/2008) Producing biofuels from oil palm plantations established on degraded grasslands rather than tropical rainforests and peat lands would result in a net removal of carbon from the atmosphere rather than greenhouse gas emissions, report researchers writing in Conservation Biology. The results confirm that benefits to climate from biofuel production depend greatly on the type of land used for feedstocks.


REDD may harm forest people, alleges report

(12/02/2008) A new report finds that the World Bank is not doing enough to protect indigenous rights under its mechanism to reduce emissions from deforestation and forest degradation (REDD).


Insect intelligence: paper wasps display strong long-term memory

(12/01/2008) A recent study in Current Biology finds that paper wasps are capable of remembering rivals a week after initially meeting. As a highly social insect, the discovery proves that the paper wasps' social interactions are based on applied memory rather than simple instinct. The finding overturns many ideas about the intelligence of insects.


Niche-based distribution modeling may help improve effectiveness of protected areas

(12/01/2008) Niche-based distribution modeling may help researchers evaluate the effectiveness of protected areas, especially in regions lacking comprehensive databases of species distribution, reports a new analysis published in the December issue of Tropical Conservation Science.


Tropical dry forest fragments important to conserving reptile biodiversity in Colombia

(12/01/2008) An important task in tropical conservation is to understand which species are particularly vulnerable to extinction, and identify the characteristics that put them at risk. Because habitat loss and fragmentation are at the root of the global extinction crisis, an extensive collection of literature has developed around profiling species assemblages in fragmented landscapes. It is also clear that species may respond differently to fragmentation, but many species experience direct or indirect negative effects, sometimes resulting in local extirpation in habitat patches.


Lack of information may slow conservation response to amphibian crisis

(12/01/2008) The Neotropics harbor between 30-50% of the world's reptiles and amphibians, but dramatic declines in both groups have been observed over recent decades. While a number of factors have been cited, many of the causes of reptile and amphibian declines are still poorly understood. The situation is paralleled by a lack of information of the natural history, ecology, and behavior of many species.


The number of endangered amphibians in Peru may be underestimated

(12/01/2008) The number of threatened amphibian species in Peru may be significantly underestimated, increasing the risk that conservation decisions will fail to account for their needs, report researchers writing in the December issue of Tropical Conservation Science.


Rural depopulation to have biodiversity impacts

(12/01/2008) Urbanization -- and accompanying rural abandonment -- may have profound implications for global biodiversity and therefore should factor into conservation planning, argue researchers writing in the December issue of Tropical Conservation Science.


Co-management of conservation areas offers multiple benefits

(12/01/2008) The Serengeti (Tanzania, East Africa)—one of the flagship conservation areas of the world—is the focus of a new paper published in the December issue of Tropical Conservation Science by Jafari R Kideghesho and Paul E Mtoni. The authors argue that conservation in the Serengeti needs to be approached as co-management involving sharing of power, responsibilities, and rights and duties between the government and local resource users. They advocate for intensive community involvement and reactivation of local traditional institutions in co-management approaches.


New hope of curing amphibian plague

(11/28/2008) Amphibians worldwide are in trouble. One of the most endangered animal groups, amphibians are increasingly threatened by habitat loss, pollution, and climate change. However the largest threat is chytridiomycosis, a devastating disease caused by a parasitic chytrid fungus known as Batrachochytrium dendrobatidis, otherwise known as Bd.


A new reason to ban whaling: your health

(11/28/2008) Health officials have recommended a ban on the eating of pilot whales, a traditional food source, in the Faroe Islands, reports New Scientist. The build-up of toxins — which bioaccumulate up the food chain as predators feed on tainted organisms — have rendered whale meat harmful to humans.


Invasive ant interferes with gecko's role in pollinating endangered plant

(11/28/2008) Invasive ants are destroying the symbiotic relationship between a colorful gecko and a critically endangered flower on the island of Mauritius, reports New Scientist citing research published by Dennis Hansen and Christine Müller in the journal Biotopica.


Captive breeding of monster Amazon fish could feed people and save it from depletion

(11/26/2008) A new technique for sexing a giant Amazon fish may help create a sustainable source of protein in South America, report researchers writing in Fish Physiology and Biochemistry.


Guide to reducing emissions through forest conservation released

(11/26/2008) Ahead of next week's climate meeting in Poznań, Poland, the Global Canopy Programme — an alliance of 37 scientific institutions in 19 countries — has launched a layman's guide to a proposed mechanism for cutting greenhouse gas emissions by reducing deforestation. Deforestation and land use change accounts for roughly 20 percent of global greenhouse gas emissions — a larger share than all the world's cars, trucks, ships, and airplanes combined.


Cameroon moves to protect rarest gorilla

(11/26/2008) The government of Cameroon has created a national park to help protect the world's most endangered great ape: the Cross River gorilla, reports the Wildlife Conservation Society (WCS), a group that provided scientific and technical support for the initiative.
