The effects of external factors on single or interacting populations in an ecosystem have long-term consequences for the demographic and genetic compositions of species in the ecosystem. Time-dependent variations in food supply and habitat have been shown experimentally to cause oscillations in population numbers, e.g., the work of Jillson and the work of Costantino, Cushing and collaborators. Waltman and colleagues have developed models to help understand the dynamics of forced populations in the chemostat. The speakers in this minisymposium will describe models which help to explain the effects of temporal and spatial environmental factors on population dynamics. They will discuss the effects of external manipulations such as harvesting, stocking, and migration on the composition of populations.
