Document Summary

Ecology: ecologists study levels of organization ranging from individual organisms to the biosphere, study of the interactions between organisms (biotic) and their environments (abiotic) What characters to study: geographic range/habitat, population size, population density, population dispersion, age structure, generation time, sex ratio, proportion of individuals in reproductive condition. Geographic range: geographic range: overall spatial boundaries within which a population lives, habitat: specific environment in which a population lives, as characterized by its biotic and abiotic features. Estimating population size: often a difficult task, too many, cryptic, mark-recapture methodology is one solution. Population density and body size: relationships between size and density often indicates information about resources used. Random distribution: no overall pattern, species are not attracted or appealed from each other, live in homogenous environments, no environmental variation, ex: sunflower. Can only categorize into one or the other but some species show a bit of both.
