Project Title: An integrated theoretical analysis of the influence of individual trait variation on the dynamics and persistence of small populations
As a NIMBioS postdoctoral fellow, Andrew Kanarek (Ph.D., Biology, Colorado State University, 2011) studied how small populations persist when faced with increased extinction risk. Whether individuals in these populations are confronted with an altered ecological context, for instance, an invasive species trying to colonize a new habitat outside of their native range, a disease spreading within a host population, or an endangered species trying to rebound from below their critical population size, life history variation and dispersal dynamics inevitably influence successful persistence (Kanarek et al. 2012). Based on this prediction, Kanarek studied the interaction between ecological and evolutionary processes to better understand the role of density dependence on population viability. Kanarek developed a number of individual-based simulations to investigate various adaptive responses (such as flightlessness in Lepidoptera, delayed growth and migration timing of anadromous fish, and host immune response) to novel selection pressures. Kanarek, along with former postdoctoral fellow, Xavier Thibert-Plante, also explored how the assumptions underlying differing genetic architectures influence the rate of evolution with applications for insect resistance to pesticides.
Kanarek has also been involved with other projects ranging from an analysis of invasive species performance in their new ranges (Parker et al. 2013), indirect effects of parasites in invasions (Dunn et al. 2012), an individual-based model for Johne's disease epidemiology and economy, implementing optimal control theory for agent-based models, and developing models to explore the evolution of play behavior. Upon completing his fellowship at NIMBioS, Dr. Kanarek accepted a position as a Biologist with the Environmental Protection Agency.
