In ecology, a niche is known to be the behavior of a species living under specific environmental conditions. The ecological niche includes how a population responds to the abundance of its resources and enemies. In ecology, all of the interactions of a species with the other members of its community, including competition, predation, parasitism, and mutualism. A variety of abiotic factors, such as soil type and climate, also define a species’ niche. Each of the various species that constitute a community occupies its own ecological niche. Informally, a niche is considered the “job” or “role” that a species performs within nature. A journal is a periodical publication intended to further progress of science, usually by reporting new research. Most journals are highly specialized, although some of the oldest journals publish articles, reviews, editorials, short communications, letters, and scientific papers across a wide range of scientific fields. Journals contain articles that peer reviewed, in an attempt to ensure that articles meet the journal's standards of quality, and scientific validity. Each such journal article becomes part of the permanent scientific record.
