Individual differences in behavior and social status can, in theory, determine the rate of population change and thus the threat that imperiled species face in the real world. While there has been an increase in the number of studies addressing the interface between behavior and conservation theory, a paradigm for applying behavioral knowledge to real-world conservation problems has not yet been developed.
The goal of this Working Group research is to integrate theories from behavioral ecology with quantitative techniques in demography in order to examine the effects of a variety of reproductive behaviors on extinction risk. Trained as population biologists, most of this group's research to date has focused on the effects of density dependence, environmental stochasticity, and catastrophic mortality events on the viability of endangered populations. Recognizing that this coarse approach ignores the finer subtleties of animal behavior, this team seeks to bridge the gap between behavioral ecology and population dynamics.
This research will provide practitioners with guidelines for understanding when behavior should be an important component of a particular management strategy (e.g., can behavioral cues of population dysfunction that provide cost-effective monitoring alternatives be identified?). This Working Group will use empirical data on sea lions in the Gulf of California, Mexico to develop a general framework for integrating behaviors and the demographic consequences of these behaviors into estimates of extinction risk.
