Research Interests

Conservation, behavioral and population ecology

Research Description

We study conservation, behavior and population biology toward the goals of understanding the influence of climate change, managing endangered or commercially-valuable wildlife, or by understanding the factors shaping life histories to satisfy our curiosity about how nature works. Our research combines intensive field studies based on quantitative sampling with field or lab experimentation, and modeling. Recent work has been done in California, Venezuela, and Puerto Rico.

My current research focuses on:

  1. Response of California birds and mammals to 20th century climate change as part of the Grinnell Resurvey Project
  2. Metapopulation biology of cryptic rails in a working landscape
  3. Avian parental care strategies and population dynamics
  4. Longterm studies of behavioral and evolutionary ecology of parrotlets in Venezuela
  5. Ecology of endangered or exploited species

With my students and collaborators, we have published over 175 scientific articles.  I am senior editor of the books Population Viability Analysis (University of Chicago Press, 2002) and New World Parrots in Crisis: Solutions from Conservation Biology (Smithsonian Press, 1992). I teach courses in conservation biology, population viability, and behavioral and population ecology.
