Introduction to Ecology •What is ecology? •Levels of biological hierarchy •Community Ecology – Types of interactions •What ecologists do – Detecting Patterns – Developing and testing hypotheses ***Today’s lab!
Ecology is the study of: •interactions between organisms and their environment – Environment = biotic & abiotic environment •distribution and abundance of organisms/species •A way of understanding the natural world
Levels of biological hierarchy 1.Individual organisms -Physiological, evolutionary, and behavioral ecology
Levels of biological hierarchy 2.Populations = individuals of a species living in same locale -Densities, abundance, population dynamics -TODAY!
Levels of biological hierarchy 3.Communities = different species living in same locale -Interactions between species, diversity, food webs -i.e. predation, mutualisms, competition -> TODAY as well.
