Community Ecology
Community interactions are classified by whether they help, harm, or have no effect on the species involved
Interspecific interactions that link the species of a community include competition, predation, herbivory, and symbiosis (including parasitism, mutualism, and commensalism), and facilitation
When two species engage in interspecific competition for a resource that limits their growth and survival, the result is detrimental to both species (−/−)
One species will always use the resources more efficiently, gaining a reproductive advantage that will eventually lead to local elimination of the inferior competitor, this outcome is called competitive exclusion
A species’ ecological niche is the sum of its use of abiotic and biotic resources in its environment
Resource partitioning, the differentiation of niches that enables two similar species to coexist in a community is “the ghost of competition past”
Character displacement is the tendency for characteristics to be more divergent in sympatric populations of two species than in allopatric populations of the same two species
Predation is a +/− interaction between species in which one species, the predator, kills and eats the other, the prey
In Batesian mimicry, a harmless or palatable species mimics a harmful or unpalatable one. In Müllerian mimicry, two or more unpalatable species resemble each other.
Endoparasites live within the body of the host; ectoparasites live and feed on the external surface of the host.
