Document Summary
Old animals made decisions thru life as it matured (settle, eat, associate) All decisions made in environment that varies in space and time. Habitat: environment in which an organism lives; seeks food, rest, nest sites, escape routes in habitat. Suitable habitats: good predictors of conditions suitable for future survival+reproduction. Chemosensory cue of red abalone larvae settles on surface that has potential of supplying food for future survival and reproductive success. Visual info provides useful cues; presence of already settled individuals is indication flycatchers assess quality of habitat by seeing how well neighbours are doing; (settle in areas where broods (abundant food) artificially enlarged) Some highly social animals vote on quality of habitats (worker bees dance to communicate location, site that excites most workers is chosen) Animals compete for high-quality habitats; may improve its fitness by establishing exclusive use of habitat.
