Stuff you need to know – Week 11
Consumption: herbivory vs parasitism vs predation, constitutive vs inducible defenses,
mimicry (batesian vs mullerian)
Top down vs bottom up control of predator/prey interactions
Mutualistic interactions
Indirect interactions: definition of, trophic cascade, keystone spp.
Community diversity: spp richness vs spp diversity
Cause of spp diversity: global patterns of spp diversity, productivity hypothesis, area
hypothesis, intermediate disturbance hypothesis
Island biogeography
Species/area relationship:
Equilibrium theory: extinction & colonization rates, effects of island size and isolation
View of community dynamics: Clements vs Gleason
Succession: definition of, primary vs secondary succession
Early vs late vs climax successional communities
Species interactions during succession: facilitation, inhibition, tolerance
Ecosystems, definition of, four basic components of, flow of energy vs matter in.
Tropic levels: autotrophs vs heterotrophs, consumers vs decomposers, primary
producers, primary vs secondary vs tertiary etc consumers, apex predators
Food chains vs food webs, grazing vs decomposing food webs, energy transfer
(production efficiency vs trophic transfer efficiency)
Eltonian pyramids (abundance, vs biomass, vs production), concept of ecologically
sustainable pyramid
Regulation of productivity in ecosystems, important factors in terrestrial vs aquatic
ecosystems
Regulation of productivity in ecosystems, important factors in terrestrial vs aquatic
ecosystems

Relative role of temp, water, light, and nutrients
Biogeochemical cycles

nutrient cycles – macronutrients (N, P), vitamins, and micronutrients; nutrient
cycling/loss in aquatic vs terrestrial ecosystems, nutrient limitation (ie iron limitation
in open ocean ecosystems)

global cycles: nitrogen, water, carbon, phosphorus

greenhouse gasses, carbon dioxide, global warming
