Ecologists create a new model to predict extinction risk

A new population viability model, with an accompanying web app, is helping scientists to better forecast population changes and extinction risk for imperiled species. The method was developed by ecologists at the University of Georgia River Basin Center with support from NASA and the help of federal, state and nonprofit fish and wildlife personnel.  It is already being used to manage Lahontan cutthroat trout, a federally listed threatened species in the western U.S.  According to lead author Douglas R. Leasure, former postdoctoral associate in the UGA River Basin Center, the new model solves a problem common to existing methods of estimating population viability—namely that they require an enormous amount of data for every population of interest throughout a species' range. And those data can be hard to come by.  Read more...
