Eco 12 competition II

Coexistence requires differences in

resource use, in space, in time

what is used to predict if populations of species will exclude eachother or coexist

Lotka–Volterra competition model

what does it mean when two isoclines intersect on the model

both species have zero population growth, no competitive exclusion, populations stabilize

when isoclines dont intersect, which species wins

the species whos line is on the outside

four outcomes from the model

competative exclusion of species 1, or species 2, unstable coexistence, or stable coexistence

Why do natural communities often maintain high diversity despite strong competition?

Environmental conditions vary across space and time
