Document Summary
Habitat is the distribution and quality of resources that contribute to fitness. food and water resources cover resources other organisms (conspecifics, prey) limitation (climate, niche) Non-habitat are sites that cannot support an organism, but the absence of a species alone is not an indicator. Clements: species" (resources) distribution peaks are concentrated in discrete groups. Gleason: species" (resources) distributional peaks are scattered along the gradient. Selection is the hierarchical process involving innate and learned behavioural decisions made by an animal at different geographical scales to determine a location to acquire resources. Preference is the process of selection that results in disproportional use of some biotic resources over others. 2nd order = location; location, size, shape of a home range mating, caring for offspring) 1st order = range; the geographical range of a species range and lowest at the range margins fragmentation, productivity vs. influx of individuals, competition/invasive species, habitat availability/ resources, social factors, and genetic mechanisms.
