Current Research:

    DNA analysis of population structure and subspecies composition of reestablished Peregrine Falcon (Aves, Falconidae) populations in the Midwest: Ecosystem-wide chlorinated hydrocarbon poisoning, which began in the 1940s, nearly caused the extirpation of Peregrine Falcon populations in North America. The genetic analysis of these populations before and after the 1950s from museum specimens will provide valuable information regarding the demographic and genetic shifts accompanying the extirpation and reintroduction of Peregrine Falcons in the Midwestern United States. I am planning to evaluate genetic variability in prebotteneck and postbottlenek populations using microsatellite genotyping and sequencing. The research will clarify whether genetic differentiation existed among founding stock, and whether that structure corresponded to subspecific designations, and assess the current genetic status of the Midwestern Peregrine Falcons.

    Molecular phylogenetics of the genus Tolmomyias (Aves, Tyrannidae) (with J. Tello, R. Bowie, T. Schulenberg, and J. Bates). This project involve the study of phylogenetic relationships in three genera of Neotropical birds (Tolmomyias, Onychorhynchus and Hylopezus) using mitochondrial and nuclear DNA sequences. In the case of Tolmomyias Flycatchers (Aves: Tyrannidae; five species and 34 recognized subspecies), the molecular data will help to solve species limits and evolutionary relationships in this wide-spread Neotropical genus. Tolmomyias is one of the most problematic to differentiate within genera, since most species have similar plumage coloration and patterns. Results of the analyses of the molecular dataset will be compared with morphological, behavioral, ecological and distributional datasets in order to better understand the evolutionary processes underlying the diversification of this Neotropical taxon.
