What allows species to inhabit some environments but not others? Uncovering the factors that structure species’ ecological limits is key to characterizing the historical formation of biodiversity and to predicting future responses to global change. Although much research has assessed how species’ ecological limits are shaped by their needs for growth and survival, species also need to be able to mate and reproduce. Our lab studies how species’ requirements for breeding dictate their ecological limits and their responses to global change. Click the buttons below to learn about some of our work.
