11.8.Levels of Organization and Associated Biomonitoring Measures
Individual - Organism - genetic mutations - reproductive success - physiology - metabolism - oxygen consumption, photosynthesis rate - enzyme/protein activation/inhibition - hormones - growth and development - disease resistance - tissue/organ damage - bioaccumulation Population - survival/mortality - sex ratio - abundance/biomass - behavior (migration) - predation rates - population decline/increase
Community - Abundance ("evenness") of an organism or organisms - Biomass - Density of an organism or organisms - Richness (variety) - number of species, size classes, or other functional groups, per unit area or volume, or per number of individuals. - Diversity - the richness given the relative abundance of each species or group. Ecosystem - Mass balance of nutrients.
