Document Summary
Ecology: field of biology that focuses on the interactions among organisms as well as between them and their environment. Population ecology: scientific study of the interaction of a group of individuals in a particular species with its environment combining theory with field work. Proportion used to estimate size of total population. Distance & area sampling: counting individuals along a transect line or in a quadrant. Random-walk technique: walking along a random route and counting the individuals you encounter. Removal sampling: trapping individuals, counting and then removing them. Clumped distribution: high densities of individuals in certain resource-rich areas and low densities elsewhere. Uniform distribution: clumped distribution of humans on a local scale. Species that show uniform distribution are often territorial - they protect their territory from intruders. For non-social species with the ability to tolerate a wide range of conditions. Random distribution: no compelling factor actively brings individuals or pushes them apart. Abundance: total number of individuals in a population.
