Document Summary
Species ranges: distribution and abundance: why are organisms found where they are: ubiquity of patchiness, limiting factors: abiotic gradients and ranges of tolerance, climate: coarse global patterns of temperate and precipitation: latitudinal patterns. Ecology: the science of distribution and abundance of organisms. Global > regional > microhabitat > small microhabitats. Substances used or consumed by organism for survival. ex) nutrients, nitrogen in soil, food on a dinner plate. Gradients can occur from one extreme to another. Organisms perform best at certain levels > certain points within a gradient. ex) Extreme conditions at the death zone on mt. Two mice in an area will be exposed to the same temperatures. Those mice will perform better at the ideal temperature they"re adapted to. Survival is most basic, then growth, then reproduction. The centre of the standard curve is 25-30 c (r r) Left of s might be 5 c, right of s might be 50 c.
