BIOL 308 Lecture Notes - Lecture 9: Resource Consumption, Metapopulation, Intraspecific Competition
Document Summary
The rate of resource consumption is going to be saturated at some point, and so does the rate of population growth at a infinite resource. Species with lowest r* wins competition (more efficient) (assume same mortality rate, and they consume the same resources) rate, and they consume the same resources) Consumption vector depends on the property of the population and environment. Equilibrium population is somewhere on the 0 isocline. In vector form, the two vectors are opposite direction, same size. Supply point at 2, one species extinct (still no competition) (lower isocline is more efficient and outcompetes) Supply point at 3, both species survive and compete. If each species is more efficient on one resource, can lead to coexistence. The consumption vector c1 and c2, the horizontal component corresponds to how much it consumes r1, vertical corresponds to r2. At point 3, species 1 outcompetes species 2. At point 5, species 2 outcompetes species 1.
