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.


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.


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.


Moving species may be only way to save them from climate change

(07/17/2008) Desperate times call for desperate measures, according to a new paper in Science. conservation scientists from the US, the UK, and Australia are calling for the consideration of a highly controversial conservation technique: assisted migration. According to the policy piece, species would be relocated to sites "where they do not currently occur or have not been known to occur in recent history".


Discovery of new leatherback migration route may help save species

(07/15/2008) Scientists have discovered a new migration route for the world's largest turtle, the leatherback. The route takes the 2,000-pound marine turtle from the Playa Grande beaches in Costa Rica to an area deep in the South Pacific.

(07/15/2008) The first hatching of Green Turtles recorded as a direct result of efforts to protect the species in southwest Madagascar has been witnessed by marine conservationists working for British charity, Blue Ventures conservation.


Tiny lemur species discovered in Madagascar

(07/14/2008) Researchers have discovered a previously unknown species of mouse lemur on the island of Madagascar. The find brings the global number of mouse lemurs to 16.


Tasmanian devil reproduction adapts to devastating, contagious cancer

(07/14/2008) Tragic circumstances have led to some astounding behvaioral changes in Tasmanian devils. A contagious form of face cancer has engulfed the population, causing the species to be listed as endangered in May. The cancer, which is characterized by large facial tumors, often leads to death by starvation. Casualty rates for infected areas are nearly 90 percent. However, a new study shows that the Tasmanian devils are not taking the disease lying down. The devils, which usually wait until two years for sexual maturity, have begun to breed within their first year of life.


Birds face higher risk of extinction than conventionally thought

(07/14/2008) Birds may face higher risk of extinction than conventionally thought, says a bird ecology and conservation expert from Stanford University. Dr. Cagan H. Sekercioglu, a senior research scientist at Stanford and head of the world's largest tropical bird radio tracking project, estimates that 15 percent of world's 10,000 bird species will go extinct or be committed to extinction by 2100 if necessary conservation measures are not taken. While birds are one of the least threatened of any major group of organisms, Sekercioglu believes that worst-case climate change, habitat loss, and other factors could conspire to double this proportion by the end of the century. As dire as this sounds, Sekercioglu says that many threatened birds are rarer than we think and nearly 80 percent of land birds predicted to go extinct from climate change are not currently considered threatened with extinction, suggesting that species loss may be far worse than previously imagined. At particular risk are marine species and specialists in mountain habitats.

Pine beetles attack Canada, boosting GHG emissions

(07/10/2008) The mountain pine beetle, a small tree-devouring insect, has deforested an area of British Columbia the size of Louisiana — over 130,000 square kilometers. The 5 millimeter insect is a perfect tree-destroying machine. The beetles bore through the tree's bark to reach the phloem of the tree, which contains the tree's organic nutrients. The beetles then feed on these nutrients and lay their eggs. The trees defend themselves by secreting extra resin, but the beetles are often able to combat this by releasing a blue fungi. In about two weeks time, the tree turns a tell-tale red and essentially starves to death. The mountain pine beetles move on.


Volunteering with Leatherback Sea Turtles in Galibi, Suriname

(07/08/2008) The northern coast of Suriname is one of the best places in the world to view the largest turtle, the marine Leatherback. Watching the turtle rise out of the tides onto the beach gives one the sense of meeting something ancient, rare, and more sea-monster than marine turtle. Yet, if I call it a sea-monster, I do not mean that it is frightening or ugly: far from it. But it is mysterious, terrible, and wondrous.


Colorful insects help search for anti-cancer drugs

(07/07/2008) Brightly-colored beetles or caterpillars feeding on a tropical plant may signal the presence of chemical compounds active against cancer and parasitic diseases, report researchers writing in the journal Frontiers in Ecology and the Environment. The discovery could help speed drug discovery.


New math shows that threat of extinction is underestimated globally

(07/07/2008) For some species the odds of survival may have changed. According to a new study current extinction models have underestimated the threat of extinction by not factoring in differences among individuals in a population. Such differences include the ratio of males to females, size and health of animals, and individual behvaioral patterns. A study conducted by Brett Melbourne of University of Colorado, Boulder and Alan Hastings of the University of California, Davis, shows that the new model speeds the extinction time for some species up to 100 times what was previously thought.


Cuteness determines whether the public will support saving species from extinction

(07/07/2008) How much would you pay to prevent the extinction of the humpback whale? The giant panda? Or how about the red-cockaded woodpecker, the striped shiner, or the water vole? With finite funds and increasing threats to species, should such decision be made on popularity, perceived utility, or ecology?


Orangutan populations drop due to logging, expansion for palm oil

(07/03/2008) Orangutan populations have fallen sharply on the two islands where they still live, reports a new study published in the journal Oryx.


Parks help people to the detriment of biodiversity, suggests study

(07/03/2008) The establishment of nature reserves in Africa and Latin America has been a boon to human settlement but comes at a cost to biodiversity, suggests a new study published in the journal Science. Analyzing 306 rural protected areas in 45 countries in Africa and Latin America, George Wittemyer and colleagues found that the rate of human population growth along the borders of reserves was nearly twice that of neighboring rural areas.


CO2 emissions could doom fishing industry

(07/03/2008) Aside from warming climate, rising carbon dioxide emissions are contributing to ocean acidification, threatening sea live, warn researchers writing in the journal Science. This trend makes it all the more important to reduce emissions, argue the authors.


Planet of the Apes Has Arrived, and It Is Spain

(07/03/2008) Visiting Spain's Barcelona zoo as a child, I was greeted to a memorable sight. In one of the cages sat a gorilla, but not just any primate. I had come face to face with the legendary albino ape "Little Snowflake." Because of Snowflake's white coat, when I looked at him I felt like I was peering into the eyes of a wizened old man. The only difference was that Snowflake's eyes were pink!


Chinese prefer tigers in the wild over tigers on their plates

(07/02/2008) A new survey shows that most Chinese would rather have tigers living in the wild than tiger products on their dinner plates. However the poll also revealed some notable contradictions in attitudes toward the trade in tiger parts.


Nepal's tiger population plummets due to poaching

(07/02/2008) Nepal's tiger population have plummeted due to poaching and a booming trade in their parts, according to a government survey released Tuesday.


Meet Spook, the world's oldest gray seal

(07/02/2008) At the age of 43, Spook is the oldest gray seal on record at any aquarium or zoo in the world. He has surpassed his gray seal relatives in the wild that can live to 30 years of age. Spook may be a senior citizen among seals, but retirement is not on his radar.


Census of marine life opens with 122,000 species

(07/01/2008) Discovering a new species can be the highlight of a biologist's career. Yet once a species enters the formal literature, complications may develop. The systen has been especially problematic because for centuries biologists have lacked the tools to construct a full and flexible list of the world's innumerable species. Using the Internet and hundreds of scientists around the world, the Census of Marine Life is attempting to take on this monumental task.


Chameleon has shortest life span of any four-legged animal

Rare golden primates help speed recovery of endangered Brazilian forest

(06/09/2008) The endangered golden lion tamarin — a flagship species for conservation efforts in Brazil's highly threatened Atlantic Forest or Mata Atlantica — plays an important role in seed dispersal, thereby helping forest regeneration, according to research published in the June issue of the open access e-journal Tropical conservation Science.


Biodiversity data gap impedes research and conservation efforts

(06/09/2008) Biodiversity loss is occurring at an alarming rate around the world. Species are found in the greatest numbers in the tropics and as these areas are impacted by an increasing intensity of human pressure, the status of animal and plant life within them is in many cases in severe decline. International legislation, such as the 2010 Target of the Convention on Biological Diversity, requires countries to measure trends in biodiversity, and also monitor progress towards lowering the rate of biodiversity loss.


Dung beetles persist in long-term forest fragments but may suffer from hunting of large animals

(06/09/2008) Dung beetles bury animal dung to use as their own food and to provide food for their young. This group of beetles is especially prevalent in tropical rainforests. Their burying behvaior incidentally contributes to ecosystem functioning and health by the removal of waste, control of dung-breeding pests, soil fertilization and aeration, and the secondary burial of intact seeds found in mammal feces. Because of their important roles in ecosystems, it is important to know how they are affected by habitat change, in this case, habitat fragmentation.


Mexican canyon serves as key refuge for endangered spider monkeys

(06/09/2008) A picturesque canyon in Chiapas, Mexico is serving as an important refuge for the northernmost population of Spider monkeys, reports a study published in the June issue of Tropical conservation Science.


Argentina's primates under threat from agriculture

(06/09/2008) Five species of non-human primates inhabit in northern Argentina: black and gold howlers, brown howlers, black capuchins, brown-capped capuchins, and owl monkeys. Although two of these species are clearly endangered (brown howlers and owl monkeys), populations of all other species are disappearing due to anthropogenic changes of their habitats. Most of the forests where these species inhabit are under continuous alteration and degradation due to soy, rice, and forest plantations, and exotic pastures for livestock. Moreover, protected forests in Argentina are insufficient to protect these primates.


Dried-up Colorado takes toll on giant Mexican fish

(06/08/2008) The Colorado River vanishes before it reaches the Sea of Cortez in all but the wettest years. Companies in California and the southwestern U.S. have diverted its once-vibrant flow to quench their thirst for water and power. Now, a new study in the April 2008 issue of the journal Biological conservation reports that the dwindling of this major artery has changed the way some marine fish in the Gulf of California grow and develop.


Rainforest species particularly vulnerable to global warming

(06/08/2008) Tropical species may be particularly vulnerable to global warming due to their limited ability to adjust to high temperatures, warn scientists writing in the journal Science.


Scientists aim to catalogue tropical island from mountaintops to seafloor

(06/04/2008) Scientists are launching an effort to catalogue a complete tropical ecosystem, the first time anyone has attempted such an ambitious undertaking. Led by researchers at the University of California, Berkeley, a U.S.-French team plans to collect DNA "barcodes" for every animal, plant, and fungus on the small island of Moorea in the South Pacific, scouring habitats from coral reefs to high-reaching cloud forests. The island could eventually serve as a model for how ecosystems respond to stresses such as climate change, invasive species, and pollution.


Diversity in streams may brace Chinook salmon for climate change

(06/03/2008) Chinook salmon face a one-two punch. They have disappeared from several rivers in the western U.S. largely because of human interventions and some populations are threatened or endangered. Numbers of Chinook in California's Central Valley have dwindled by 88 percent in the past five years, a loss that closed fisheries for 2008 and may cost California's economy $167 million, according to the state Department of Fish and Game. On top of all this looms a second impact: These salmon will be in hotter water still because of climate change.


Roads are a major killer of amphibians, reveals study

(05/29/2008) Frogs, toads, and salamanders worldwide are dying from mysterious causes, with possible culprits ranging from habitat loss to fungal diseases. Now, researchers at Purdue University believe they may have identified a significant and surprising contributor to global amphibian declines: traffic. In a recent study, the scientists looked at road kill along several stretches of road in northwestern Indiana and found that 93 percent of the dead animals were amphibians.
