BIOL 2060 Chapter competition: final reading (competition)
Document Summary
Niches and environmental tolerance: which of factors might determine where asian tiger mosquitoes can survive in florida, presence of competitors, presence of humans, presence of standing water. Classifying mechanisms: small bushes tend to be found in clusters while larger bushes tend to be more evenly distributed, suggesting that this pattern was driven primarily by competition. Intraspecific competition in mosquito larvae: individual larvae grow more slowly in crowded (high density) populations. The simplest explanation for this is: at high densities there is less food available for each individual. The equation is: = (cid:4672)1 (cid:4673, where dn/dt is the population growth rate, r is the maximum per-capita population growth rate, n is the current population size, k is the population carrying capacity. This would mean that the combined number of intraspecific and equivalent interspecific competitors is less than the carrying capacity of species 1.
