competitive release
Hypothesis that parasitism of dominant plant species reduces their competitive ability, allowing less competitive species to increase in abundance
mass ratio hypothesis
Species with greater primary production exert the main controls for the functioning of ecosystems due to greater aboveground abundance of biomass or leaf area that promotes resource uptake
Dobzhansky-MacArthur hypothesis
Predicts that a species' high-elevation range limit is determined by harsh abiotic conditions whereas its low-elevation range limit is set by antagonistic species interactions
Gloger's rule
A relationship between plumage coloration and climate variation, predicting that darker coloration due to pigmentation occurred in warmer, more humid tropical regions while lighter colors occurred in ...
