I will be teaching Conservation Genetics (BIOL 320) spring 2009. As a part of the interdisciplinary study of Conservation Biology, Conservation Genetics has grown to establish its own ground in 1980s. We will learn how population genetics and molecular phylogenetic analyses can be applied to species conservation. The course will be offered as a seminar format. While student presentation and discussion will be an important part of the course, I will give lectures providing enough background information for student activities. There will be no lab section.
My interests broadly rest on evolutionary ecology, behavioral ecology and conservation biology. Despite rich species diversity on the earth, processes of species diversification have not been fully understood. I am especially interested in ecological speciation, in which reproductive isolation evolves through ecological processes (i.e., divergent selection). My research approach to conservation biology is to explore pesticide effects on non-target species such as amphibians, while I am also very interested in invasive species. I am tackling these issues using amphibians, insects and plants as study organisms. Here at Bucknell, I am collaborating with Dr. Abrahamson on host-race formation via insect-plant interaction.
