Document Summary
Ecology: science of understanding (emphasis on why and abundance) Misconcepions: won"t always return to original state, many species are redundant. Ecological maxims: organisms interact, interconnected, everything goes somewhere, non pop can increase forever, finite e and res = trade ofs, organisms evolve, ecosystem change over ime, spaial scale maters. Nat selecion: certain adaptaions live longer, reproduce more. Net primary producivity: e captured cellular respiraions. Ecosystems work from nutrient cycling and e gain/loss. Amphibians are like biological indicators, easy exposure to pollutants, cycle of parasite hosts. Parasite caused disease in frog, ferilizer and pesicide increase likelihood, weren"t direct cause. Pesicides lethal due to stress from predator presence, frog pop went up when ish removed. Biomes: organic/physical features, mainly described by climate and dominant plants (sessile) Convergence: similar growth forms with litle to no geneic relaion (caci) Water/temp main determining factors and then soil health.
