Thesis Defense: Kristen Richardson!

As part of the Wildlife Seminar this Monday, June 3, Kristen Richardson will be defending her Master’s Thesis, “Using non-invasive techniques to examine patterns of black bear (Ursus americanus) abundance in the  North Cascades Ecosystem.”

Her talk begins at 3:30 p.m. in Kane 130 and is open to the public, so come support the culmination of her research at SEFS!

And what will Richardson be talking about?

From 2008 to 2011 a large, multi-agency project deployed barbed-wire hair-snag corrals to collect DNA samples from black bears (Ursus americanus) in the North Cascades Ecosystem (NCE) of Washington State. Using the genetic and detection data, Richardson examined the influence of human activities and habitat characteristics on bear abundance across heterogeneous landscapes of the NCE.

No other research to date in Washington State has examined the influence of habitat and anthropogenic variables on black bears across such a large geographic expanse, and the results of her study should help guide management of black bear populations in the NCE. This research is especially important given the challenge of maintaining viable populations of a long-lived species with relatively low fecundity.

Richardson’s committee chair is Professor Aaron Wirsing, and the other members are Bill Gaines and Josh Lawler.
