Document Summary
Clements s climax community: communities are stable & x ch -> determined by area s climate. Gleason s view: communities x stable & x predictable -> individual species respond independently to physical variables to determine their distributions. Biological diversity: all life on earth => 1. Genetic diversity (variation within a species" genes) 2. Ecosystem diversity (variation of species across ecosystems or ecosystems within 1 area) Intermediate disturbance hypothesis: communities that exp intermediate lvs of disturbance highest possible species richness cuz more species coexist within community if disturbance is 1. Intermediate -> x favour anyone but both types persist. Biodiversity hotspot: area w/ high biodiversity ( many endemic species) that is threatened w/ habitat loss (generally due to human action) e. g. coral reef - marine hotspot cuz (func) 1. Natural barrier that protects shorelines from storm surges & erosion due to regular wave action 2.
