Patreon episode - what’s up with Central American vipers? More specifically how is there size and shape impacted by location and interspecific interactions? We check out a couple of papers looking to explore just that. The Species of the Bi-week is a new moderately small insular viper. FULL REFERENCE LIST AVAILABLE AT: herphighlights.podbean.com

056 The Ecology of Snakebite
Thursday Oct 10, 2019
Thursday Oct 10, 2019
Snakebite is a worldwide phenomenon which has dramatic consequences for human health. But how does the ecology of snakes influence its incidence and severity? We first look at snakebite globally, and then focus in on a famous island. Our Species of the Bi-Week is a recently described tree-dwelling serpent.
