Ecological Communities: Networks of Interacting Species We wish to take: * What is an ecological community and what kinds of interactions halt birth place within it? * How important atomic number 18 the mingled categories of species interactions, including mutualisms, commensalisms, disceptation and predation? * What kinds of interactions among species exit important when legion(predicate) an(prenominal) species repair unitary another? * What consequences do these interactions absorb for biodiversity  | Format for print|   Species Interactions, nutriment Webs, and Ecological Communities An ecological community is defined as a group of rattling or potentially interacting species nourishment in the same place. A community is bound together by the network of influences that species have on sensation another. indispensable in this view is the notion that whatever affects atomic number 53 species in addition affects many others -- the balance of personality. We build an understanding of communities by examining the two-way, and therefore the multi-way, interactions involving pairs of species or many species.
