Biological Species Concept. The biological species concept defines a species as members of populations that actually or potentially interbreed in nature, not according to similarity of appearance.Although appearance is helpful in identifying species, it does not define species.Appearance isnt everything.1  Organisms may appear to be alike and be different species. 2  For example, Western meadowlarks (Sturnella neglecta) and Eastern meadowlarks (Sturnella magna) look almost identical to one another, yet do not interbreed with each otherthus, they are separate species according to this definition.ppearance isnt everything. 1  Organisms may appear to be alike and be different species. 2  For example, Western meadowlarks (Sturnella neglecta) and Eastern meadowlarks (Sturnella magna) look almost identical to one another, yet do not interbreed with each otherthus, they are separate species according to this definition.
Other definitions include: 1. An introduced, non native species, or a species that is the result of direct or indirect, deliberate or accidental introduction of the species by humans, and for which introduction permitted the species to cross a natural barrier to dispersal (Noss and Cooperrider 1994).nvasion biology is the study of these organisms and the processes of species invasion. The terminology in this page contains definitions for invasion biology terms in common usage today, taken from accessible publications. References for each definition are included.
