Ecological Communities: Networks of Interacting Species We wish to learn: * What is an ecological community and what kinds of interactions take a crap birth place within it? * How important are the heterogeneous categories of species interactions, including mutualisms, commensalisms, disceptation and predation? * What kinds of interactions among species become important when many an(prenominal) species tinct unitary another? * What consequences do these interactions have for biodiversity  | Format for effect|   Species Interactions, nutriment Webs, and Ecological Communities An ecological community is defined as a group of actually or potentially interacting species accompaniment in the same place. A community is bound unneurotic by the network of influences that species have on sensation another. inwrought in this view is the notion that whatever affects one species as well affects many others -- the balance of nature. We build an understanding of communities by examining the two-way, and therefore the multi-way, interactions involving pairs of species or many species.
