Studies in ecology in the Division of Biological Sciences span scales from genes to landscapes, explore a diverse array of organisms, and employ an extensive array of approaches. Areas of particular interest include evolution of communication, speciation, population genetics, habitat fragmentation, and conservation management. Studies cover a range of organisms, from plants and insects to birds and elephants, in laboratory studies and in natural habitats across the world. They combine theoretical modeling with field and laboratory studies. Research in this area benefits from a larger, interdisciplinary Conservation Biology certification program.
