Document Summary
Structure depends on environmental circumstances: example: grassland, temperate forest, muskeg, life history and ecological succession, early/late succession, early: small biomass, short lived, low species diversity, life history type r. Late: large biomass, long lived, high species diversity, life history type k: facilitation, tolerance, and inhibition succession models, facilitation: many species may attempt to colonize a new space but only certain ones with certain characteristics are able to. These early species facilitate colonization of later species. Less suitable for early successional species, suitable for late successional species. The ones that survive are the ones that don"t change the environment: tolerance: initial stages are not limited to early species, nor do they make the environment favourable for later species. The climax communities are the ones that can tolerate changes by earlier species and no other species can tolerate those conditions.
