Meanwhile, human beings have also been working to counteract the effects of their development and growth as well as man-made climate change. Measures like the U.S. Endangered Species Act, habitat-protecting nature reserves and hunting prohibitions are all designed to slow the rate of extinction and preserve dwindling species...
It's not hard to understand Traill's logic - the smaller a species population becomes, the more vulnerable it is to extinction. Not only are small, dispersed populations more easily wiped out, but also they are more susceptible to inbreeding, which leads to a decrease in genetic diversity and further...
But Traill and his colleagues, after reviewing the most current data, found that a better rule would be 5,000 - meaning no fewer than 5,000 adult individuals are needed to keep a species safe from the threat of extinction. Dip below that level, and any sudden change - the loss...
