Document Summary
Number of species per specified sample area or specified number of individuals. Large scale diversity is constantly increasing, does not level off. Global scale: why doesn"t ontario have the same species as. Difference if species and specie interactions (plants, insects, trees) Distinguishing biomes mountains are a large influence. Higher latitudes species diversity (biodiversity) decreases, population size increases. Field observation of actual range of distribution. Correlation of environment gradients and species optimum range. Germino & smith (2002), physiological ecologists transplanted engelmann spruce (picea engelmannii) seedlings above treeline in wyoming. Treatments: underneath herbaceous canopy (shaded, competition for water, on bare soil (lots of light, no competition, on bare soil, surrounded by herbaceous canopy (lots of light, competition for water) Abundance percent cover, biomass or frequency of individuals per species. Abiotic non-living physical and chemical factors that affect the ability of organisms to survive and reproduce. Biotic living factors; all the living things that live within and shape an ecosystem.
