Habitat selection research examines how organisms make use of their environment. This research area has moved beyond mere documentation of habitat that organisms use, by striving to understand why an organism selects a particular habitat and to determine the mechanisms that drive a population of organisms to inhabit certain areas. There are limitations on inference that result from issues such as definitions of habitat selection and availability, scale, spatial and temporal autocorrelation, and locational imprecision. Nevertheless, habitat selection is an incredibly powerful area of research that has the potential to inform ecology through analysis of organism–habitat associations.
