Specifically: Ecology of birds and their habitats, Arctic ecology, wildlife conservation, monitoring, and management
I’m interested in the ecology and conservation of arctic birds and their habitats. Two key themes of my research are 1) evaluating the influence of changing conditions in the Arctic on the breeding ecology of tundra birds and 2) developing innovative approaches to improve knowledge of population status. Techniques range from population-level demographic analyses to individual-level behavioral studies and my work is carried out from remote arctic breeding sites to temperate migration stopovers. An important focus of my current work is to understand the effects of overabundant arctic geese on sympatric species such as shorebirds and gulls. Several populations of arctic geese have increased exponentially in abundance in recent decades, in large part due to nutritional subsidies during the non-breeding season. These now overabundant geese, especially Midcontinent Lesser Snow Geese, have caused considerable damage to arctic habitats. Few studies have evaluated the impact of overabundant geese on other birds but the possibility exists for strong effects mediated through habitat change or altered predator/prey dynamics. My work evaluates the mechanisms and magnitude of effects of geese on other tundra nesting birds and their habitats. Another key current project involves the use of tracking technology to enhance the monitoring of bird populations. We’re combining modern technology with modern statistical methods to integrate behavioral data into monitoring programs, in order to improve our understanding of birds’ population status. My research seeks innovative solutions to conservation challenges and I would be interested to hear from potential graduate students that share this interest.
