Assessment of Structural Changes changes in species / population structure - appearance/disappearance of an indicator species - number of individuals of a species - biomass of a species - presence or absence of a species Biomass-a quantitative estimate of the total mass of living plant or animal materials
changes in community/ecosystem structure - biomass - abundance - biotic indices (e.g. trophic types) - species richness / diversity - dominance - food chain length/complexity
