LECTURE OUTLINE
... 33.3 Regulation of Population Growth Members of opportunistic populations are small in size, mature early, and have a short life span. Equilibrium pattern organisms are fairly large, slow to mature, and have a fairly long life span. Abiotic factors, such as weather and natural diseases, are density- ...

Interactions among species
... No two species can occupy exactly the same niche in exactly the same habitat at exactly the same time. If there are two species, one will be better at competing for limited resources and will eventually exclude the other species. ...
