Key Concepts

Dispersal and Colonization

The ability of species to disperse and colonize new habitats affects the species composition of a community. Limited dispersal may prevent certain species from reaching suitable habitats, while effective colonization can lead to the establishment of species whose traits allow them to exploit available niches in a particular environment.

Biotic Interactions

Interactions among living organisms, such as competition, predation, parasitism, and mutualism, play a crucial role in determining which species can coexist in a community. These relationships can either facilitate or inhibit the establishment and persistence of species, thereby influencing community structure.

Abiotic Environmental Factors

Abiotic factors such as temperature, moisture, soil type, and nutrient availability set the environmental conditions that a species must tolerate to survive. These factors filter the species pool by favoring those with adaptations that meet the local physical conditions, thus shaping the community's species composition.
