Document Summary

A biological community is an assemblage of populations of various species living close enough for potential interaction. Concept 54. 1: community interactions are classified by whether they help, harm, or have no effect on the species involved. Ecologists call relationships between species in a community interspecific interactions: Strong competition can lead to competitive exclusion, sometimes the local elimination of a competing specie. Competitive exclusion limiting resources cannot co-exist in the same location permanently e. g. - gause"s competitive exclusion principle: two species competing for the same. Green and brown anoles unless: spacial where the two are found together, the green anoles are more common on the vegetation and higher up, while the brown. A species" use of biotic and abiotic resources is called the species" ecological niche. A species" fundamental niche - niche potentially occupied by species. A species realized niche - niche actually occupied by species: as a result of competition, a species fundamental niche may be considerably reduce.
