Ep. 286 - Grappling With Plant Extinctions

This episode is all about one of the most difficult topics in natural history - extinction. Plants set the foundation for nearly all life on Earth and yet they receive a mere fraction of the attention and effort needed to conserve them. Recent estimates indicate that 40% of the world's plant species are threatened with extinction and that is a scary statistic. One of the biggest hurdles in the fight against plant extinction is figuring out which plants are most at risk. Thanks to my guest today, we now have a much better idea of plant extinctions in North America. Joining is North Carolina Natural Heritage Program Botanist, Wes Knapp. Wes and his colleagues recently published a comprehensive review of plant extinctions in North America which helps set the stage for future conservation efforts on this continent. Join Wes and me as we sit down and grapple with this difficult subject.

Ep. 152 - Forests, Ozone, and Earth's Largest Mass Extinction

The End-Permian Extinction occurred some 252 million years ago. It has been referred to as "the day the earth nearly died.  It is estimated that the world lost up to 96% of all marine species, 70% of terrestrial vertebrate species, and 83% of all insect genera alive during that time. Life on this planet took much longer to rebound than at any other time in history. Though we know volcanism played a roll in this extinct, paleontologists have always been looking for a mechanism that could connect the two. Thanks to Jeff Benca and others, we now have an idea. In this episode we talk about how weakening of the ozone layer led to massive forest declines around the globe. This in turn had serious ramifications for the rest of the biosphere. This work not only fills a big gap in our prehistoric history, it tells an alarming tale for our future if we continue to disregard habitat destruction. This is one episode you don't want to miss.
