“No man is an island entire of itself. Every man is a piece of a continent, a part of the main”-John Donne

What is Ecology? The study of the interactions of organisms

with one another and with their physical environment.

Biotic Factors Organisms that are living (or WERE living at one

time….paper, steak)

ex- animals, plants, bacteria, fungus

Abiotic Factors Physical Environment (non-living)

ex- water, air, dirt, rocks

FYI…

Latitude (shown as a horizontal line) is the angular distance, in degrees, minutes, and seconds of a point north or south of the Equator. Lines of latitude are often referred to as parallels. Longitude (shown as a vertical line) is the angular distance, in degrees, minutes, and seconds, of a point east or west of the Prime (Greenwich) Meridian. Lines of longitude are often referred to as meridians.

Species Richness:The number of different species in a community.

Species Diversity: a measure of both species richness and the relative abundance of each species. A community with the same species richness can be less diverse if, on average, there is much greater abundance of some species over others.

Ch 53#11: How is species richness of a community related to (1) geographic isolation; (2) the structural complexity of the habitats?
