Since biblical times people have entertained the concept that animals could be saved from extinction in a man-made sanctuary. The concept … Continue reading Can we save a migratory vulture population with captive-raised birds?

Kevin Smith and Ryan Almeida take a look at how we can predict and manage extinction risk.  Here’s a thought experiment for you: ask a few people the question, ‘What was it about the dodo that led it to go extinct’? Compare your answers. Based on our experience, your friends and colleagues are likely to cite some of the dodo’s traits that they feel like … Continue reading If some species extinctions are the result of bad luck, what does this mean for conservation?
