Notes:
Summary Habitat selection whereby individuals within a population have different microhabitat preferences is possibly important for genetic diversity and stability. It has received a good deal of attention, especially forDrosophila populations. The literature is summarized and an attempt is made to reconcile what appear to be contradictory findings. Some generalizations are drawn: (1) individualDrosophila choose habitats in consistent and characteristic ways; (2) some microhabitat differences are more important to flies than others; (3) genetic factors influence habitat preferences; (4) experiential factors influence habitat preferences; (5) differences in processing ability moderate the influence of experience on habitat choice. It is argued that the traditional analysis of variance models are frequently not very helpful for visualizing the process, and a computational model is suggested instead.
