Welcome to the Chalcraft Lab! We have a broad array of interests in the population and community ecology of both aquatic and terrestrial ecosystems but we primarily focus on understanding 1) the mechanisms that control the biological diversity of an area, 2) the ecological consequences of variation or change in the biological diversity of an ecosystem, and 3) factors that control the intensity of species interactions between species. We employ both experimental and meta-analytical methods to aid us in addressing these topics.
