Document Summary

D! debate lead to clements gleason dichotomy. Gleason"s ---> population present there reflect the climate ! *** on land oxygen is a condition high altitudes oxygen is a resource ---> can"t get out of it ! Too much predation species wouldn"t be present in the community. Or less resources few larger offspring fish having babies depends on the social environment. Many females they will have few and large offsprings. Not lots of females they will have a bunch of small offsprings. *** lot harder to describe communities than population bio diversity ---> 3 levels. Species count how many species are in the area. Genetic diversity within a species genes! Same exact ecosystem but not the same species! Or lots of ecosystem in the same landscape spatial heterogeneity = variation! spatial homogeneity = same shit everywhere :) ** you can see that you get peak levels of species richness when there is.
