Scientists closely examine causes of frog abnormalities

Currently, research on the possible causes of limb deformities in amphibians is expansive, with evidence supporting parasite infection, chemical contaminants, UVB radiation and amputation as possible factors. However, as Mari Reeves from the U.S. Fish and Wildlife Service and colleagues explained in an article in the August issue of Ecological Monographs, the most likely cause of  amphibian abnormalities is a combination of several...

Climate change may reorganize Western fauna

Bioclimatic models attempt to draw correlations between species distributions and climate patterns.  As ecologists and climatologists hone these models, they become a useful tool for predicting future species distributions based on projected climate patterns. In the March issue of Ecology, Joshua Lawler of the University of Washington and his colleagues undertook a huge task: using a bioclimatic model, they estimated the effects of...
