Document Summary
Species: a group of individuals that 1) share a common ancestor, 2) share significant amounts of genetic material, 3) can interbreed with each other 4) are usually reproductively isolated from members of other species. Plant population: group of individuals of the same species that live in one location and actively interbreed, includes individuals at different life stages, sapling to adult. Emerged in the cretaceous period shrubs, vines, trees, and herbs. Trees and shrubs, and cones, ie pine trees, Marginalized in stressful or less productive environments, like tundra. Abiotic/physical factors are those which are part of the physical environment. They typically occur as gradients across regions of the earth"s surface. They limit species" distribution when they reach certain levels, and it depends on the species" evolved physiological response to them. Abiotic factors tend to affect a plant"s tolerance range, which is the growth rate or performance along the gradient of a single physical factor, like ph, moisture, or temperature.
