Spiders tend to get a bad rap, but they are actually critical to the balance of our ecosystems. Kefyn Catley will explain how on Friday, July 20, as part of Discover Life In America’s Science at Sugarlands series, a free public event at Sugarlands Visitor Center at which participants will get to go on a spider hunt.
Catley, a biology professor at Western Carolina University, teaches and conducts research in the evolutionary biology of spiders. He holds a Ph.D. in arthropod systematics from Cornell, was a research scientist at the American Museum of Natural History, and has taught Spiders of the Southern Appalachians at Highlands Biological Station in North Carolina since 2004.
FF: It’s not every day you meet someone who has studied spiders on four continents. Why do you find them so fascinating?
KC: Spiders have an ancient lineage originating some 400 million years ago. They are the largest and most important group of predators on the planet and are considered a mega-diverse taxon with more than 47,000 described species with an estimated total number in the range of 75,000-190,000. Spiders are excellent models for studying ecology, behaviour, biochemistry, competition, speciation, sexual selection and biogeography, among other fields. They contribute to research in biological pest control, venom chemistry and the cloning of silk.Read more...
