An overview of resource limitation and competition.
- Section One: Limited Resources
Niches and environmental tolerance. Fundamental vs. realized niche. Competitive exclusion. Different mechanisms of competition, including exploitation, interference, territoriality, allelopathy, and preemption.
- Section Two: Intraspecific Competition
Exponential and logistic growth. Effect of competition on individual growth rates. Carrying capacity and resource availability.
- Section Three: Interspecific Competition
Competition coefficients. Lotka-Volterra competition equation. Phase planes, phase portraits, and isoclines. Four outcomes from competitive interactions. R* competition. Laboratory studies of competition.
- Section Four: Competition in Complex Environments
Field studies of competition. Common garden experiments. Competition importance across taxa. Hypotheses for competitive coexistence: environmental heterogeneity, trade-offs, interspecific interactions, and neutral theory of biodiversity.
