title: [Species: author definitions].
abstract: For a long time the definitions of species have been mainly restricted to logicians and philosophers; with the contribution of biologists, the number of concepts increased dramatically. The concepts elaborated by authors of the evolutionary synthesis seemed decisive for a time but the number of definitions proposed was never as high as in the last half century. In the present review, a list of classical or less well-known definitions are proposed with some commentaries.
