Scientists map out potential for restoring California fisher populations
01-10-2008 · EurekAlert!US Forest Service and U.C. Santa Barbara scientists believe they have identified the habitat needs for Pacific fishers, a rare California mammal that is a candidate for reintroduction efforts and listing under the Endangered Species Act. Their findings were published in the current edition of Ecological Applications.

- Sea otter study reveals striking variability in diets and feeding strategies
01-14-2008 · EurekAlert!
Ecologists have long observed that when food becomes scarce, animal populations exploit a wider range of food sources. So scientists studying southern sea otters at different sites in California's coastal waters were not surprised to find that the dietary diversity of the population is higher where food is limited. But this diversity was not reflected in the diets of individual sea otters, which instead showed dietary specialization in response to limited food.

- Floating lovers count too -- in the health of eagle populations
11-01-2006 · EurekAlert!
In a paper from the November issue of the American Naturalist, Vincenzo Penteriani, Fermín Otalora, and Miguel Ferrer, researchers at the Estación Biológica de Doñana (Consejo Superior de Investigaciones Científicas, Spain), focus on the forgotten and invisible side of animal populations -- the floaters. Floaters are dispersed individuals who enter the reproductive population when breeding territory or a potential mate become available.

- Major population centers may be at risk; building codes must reflect new seismic data
02-07-2007 · EurekAlert!
Earthquakes in stable continental regions lack sufficient understanding to prepare local populations for future seismic activity, according to a paper published in the February issue of the Bulletin of the Seismological Society of America. Scientists provide a new hazard assessment for Peninsular India to highlight the urgent need to update design standards there in order to construct adequate and safe industrial facilities, dams and community buildings.

- Mailman School of Public Health researchers report blood DNA can be early predictor of liver cancer
04-15-2007 · EurekAlert!
Researchers at Columbia University's Mailman School of Public Health have discovered a means for early detection of liver cancer. Using DNA isolated from serum samples as a baseline biomarker, the scientists examined changes in certain tumor suppressor genes that have been associated with the development of liver carcinomas. This is the first study to prospectively examine potential biomarkers for early detection of liver cancer in high-risk populations.

- UC Davis scientists' groundbreaking research: Mate-attracting chemicals
10-27-2006 · EurekAlert!
It's all about "the birds and the bees." And now, "the silkworm moths and the fruit flies."A chemical ecologist and a genetics researcher at the University of California, Davis, have joined forces to trick fruit flies into thinking that silkworm moths are potential mates.Groundbreaking research in the labs of chemical ecologist Walter Leal and genetics researcher Deborah Kimbrell shows that genetically engineered fruit flies responded to the silkworm moth scent of a female.

- Biologists produce global map of plant biodiversity
03-20-2007 · EurekAlert!
Biologists at the University of California, San Diego and the University of Bonn in Germany have produced a global map of estimated plant species richness. Covering several hundred thousand species, the scientists say their global map is the most extensive map of the distribution of biodiversity on Earth to date.

- Indigenous water frogs under threat
11-29-2007 · EurekAlert!
Indigenous water frogs can be crowded out by immigrant or imported species. This is the finding of a Franco-German study. The scientists investigated water frog populations in France and Northern Spain and noticed that the marsh frog (Rana ridibunda), which normally occurs only in Eastern Europe, has the potential to crowd out indigenous species like Graf’s hybrid frog (Rana grafi) and the Iberian water frog (Rana perezi).

- Global malaria map key weapon in fight against malaria, scientists say
12-04-2006 · EurekAlert!
For the first time in almost forty years, researchers are creating a global map of malaria risk. The Malaria Atlas Project, or MAP, will help identify populations at particular risk and predict the impact of the disease, allowing health resources to be targeted at those areas most at risk.
