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.
