Document Summary

Key: black: broad topics blue: main detail green: definitions red: examples. What is ecology: the study of interactions among organisms and their environment, goal of ecology is to determine the biological and physical factors that determine the distribution and abundance of species, understanding distribution and abundance. Why study ecology: we are all inextricably connected, allows to protect future size of population (cid:494) Ex) lyme disease: simply a change in the properties of populations of organisms that go beyond a lifetime od single individuals, changes are heritable via genetic material. Why do we study ecology and evolution together: ecology influences evolution, habitats, the physical environment and other species all affect how species evolve and adapt, evolution influences ecology, past evolution history influences the present characteristics of species. Ex) indonesia yielded 1,690(n) hempteran species of which. Biodiversity because of tradeoff: niche: have roles in the environment, plasticity: the degree to which single genotype can change in trails to response to environmental differences.
