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.


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.


Biofuels, food demand may doom tropical forests

1/3 of corals face extinction

(07/10/2008) Nearly one-third of reef-building corals are vulnerable to extinction, according to an assessment of 845 species of coral. Rising temperatures, increased incidence of disease, and human disturbance are driving the trend.


The global rich are eating the poor's fish: new report shows tropical fish catch gravely under-estimated

(07/10/2008) After a week of bad news regarding marine life — it was reported that half of U.S. coral reefs are in fair to poor condition and one-third of all coral species are threatened globally — there is still more: a study of twenty tropical islands showed that recreational and subsistence fishing has gone almost completely unreported from 1950 to 2004. In fifteen of twenty cases the fish take was at least doubled when local fish catches were added, and in the most extreme case, American Samoa, the amount of fish collected was 17 times what was previously recorded.


Palm oil industry moves into the Amazon rainforest

(07/09/2008) Malaysia's Land Development Authority FELDA has announced plans to immediately establish 100,000 hectares (250,000) of oil palm plantations in the Brazilian Amazon. The agency will partner with Braspalma, a local company, to form Felda Global Ventures Brazil Sdn Bhd. FELDA will have a 70 percent stake in the venture. The announcement had been expected. Last month Najib said Malaysia would seek to expand its booming palm oil industry overseas. The country is facing land constraints at home.


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.


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?


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.


Some grasslands resilient against climate change, according to 13 year study

(07/07/2008) In Buxton, England--a spa town lying in the county of Derbyshire--scientists have spent 13 years subjecting grasslands to temperature increases and precipitation shifts consistent with climate change predictions. Considered one of the longest studies of climate change on natural ecosystems, the grasslands of Buxton proved surprisingly resilient to most of the effects of climate change.


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.


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.


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.


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.


Welcome to the Jungle: An Introduction to the End of the Industrial Era

(07/03/2008) The existing state of industrial civilization has brought our planet and global populations into a worldwide crisis unprecedented in the history of life on Earth. Human activities have sent many living systems into decline or collapse, brought about the 6th mass extinction of biodiversity, upset our planet's biogeochemical cycles, and rapidly and dangerously altered our climate. We stand at the bifurcation point of our species: whether or not we are able to question the maladaptive behvaiors which have brought about these travesties and adapt on a global scale will determine the course of human evolution and the survival of a multitude of living organisms with which we share this planet. As the only reflectively conscious organism to have existed, we also hold the fate of (reflective) sentience itself in our actions. I believe our chance at pulling ourselves out of this mess is through an analytical dissection of human nature and behvaior — to expose, extract, examine, revise and communicate the elements of our existence which drive us into maladaptive behvaiors followed by an application of technology and action grounded in a new and emerging understanding of humanity and our position in the biosphere.


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.

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.

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.


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.

50 years after the blast: Recovery in Bikini Atoll's coral reef

(05/27/2008) Fifty years after atomic bombs rocked Bikini Atoll and pulverized its coral reef, the lagoon again boasts a flourishing coral community. Scientists diving in the two-kilometer-wide Bravo Crater, created in 1954 by a blast 1,000 times stronger than the bomb dropped on Hiroshima, Japan, found a thriving habitat with treelike corals 30 centimeters (one foot) thick. The study shows that coral reefs can recover from profound damage?when humans leave them alone.


From "kampung boy" to conservation force in the rainforest of Borneo

Group files for ESA protection of 681 species in 12 states

(05/21/2008) On March 19th WildEarth Guardians filed a lawsuit to place 681 species under the Endangered Species Act. Dr. Nicole Rosmarino, wildlife program director for the environmental group, says These 681 species represent species in only 12 states, include no subspecies, and are only the "most imperiled" of the United State's threatened species. Rosmarino estimates that in total there are 6,000-9,000 endangered species in the United States today. Mongabay.com recently caught up with Dr. Rosmarino regarding this landmark lawsuit and the reasoning for it.
