Research

Dr. Dinsmore's research is centered on the intersection of avian ecology and population biology and focuses on applied issues related to specific management questions.  His research program is important to local, state, and federal natural resource management agencies because it addresses contemporary ecological problems, provides science-based solutions to these problems, and contributes to other natural resource disciplines through methodological advances.

His research program has emphasized three primary areas.  The first focuses on measures of avian reproductive success, an area where he has played an active role in developing rigorous methods for estimating nest survival. Much of this work has focused on providing estimates of nest survival and understanding how they are influenced by extrinsic factors; however, he is also interested in broader questions such as the evolution of mating systems and understanding parental investment in reproduction.  His second primary research area deals with modeling avian demography.  He is interested in management or conservation questions and use studies of avian demography (e.g., estimates of survival and population size) as tools to address these questions.  His third primary research area deals with the influence of habitat on populations.  He is interested in working with natural resource agencies to understand the implications for bird populations of alternative habitat management practices.
