Go West, Young Lion: New Study Shows Mountain Lions Dispersing from Nevada to California


ScienceDaily (Oct. 5, 2012) — Using data collected over the course of seven years, the study looked at DNA in tissue samples collected from 739 mountain lions. In the first-of-its-kind study at this scale, the authors used only the gathered genetic information to discover population structures and history, and to identify what areas in the region serve as "sinks" (habitat that animals move to at a greater rate than they disperse from) and "sources" (areas that animals disperse from at a greater rate to live elsewhere).
The study, "Identification of Source-Sink Dynamics in Mountain Lions of the Great Basin" appears online in August's early-view edition of the journal Molecular Ecology. Authors of the study include: Alyson M. Andreasen of the University of Nevada; Jon P. Beckmann of WCS; and Matthew L. Forester, William S. Longland, and Kelley M. Stewart of the University of Nevada.
