Last update June 1, Skip to main content Skip to main navigation menu Skip to site footer. Abstract There actually is no species problem per se in systematics. Rather, there is a taxon problem. This review argues that a decision must first be made about what entities taxon names are to represent in general. Then, species taxa should be the same kind of things, but just the least inclusive taxa that are named using the formal Linnaean nomenclatorial system.

Formal classifications are meant to serve purposes of communication, data storage, predictivity, and function in theories. These purposes are best served by naming only phylogenetically natural, monophyletic groups. These are groups containing meaning of phylogenetic in biology and only descendants of a common ancestor. A phylogenetic species concept can thus be defined, based on a generalized view of the meaning of monophyly and synapomorphy.

In the process of building a classificationtaxonomic groups are recognized on the basis of clear support for their existence as monophyletic cross-sections of a lineage. Also, formal taxa are named considering their utility in developing and discussing evolutionary process theories. Downloads Download data is not yet available. PDF Español. How to Cite. Mishler, B.

We ot several factors that might be related to the home-range size of felids at both inter and intraspecific levels. Pantheria: a species-level database of life history, ecology, and geography of extant and recently extinct mammals. Furthermore, home range size of these three felids seems to be strongly infuenced by reproductive attributes as well as by habitat quality, suggesting a connection with the spatial distribution of both food prey and mates. With this variety of disciplines, I questioned whether the argument would be settled by the end of the book, or not. Blink Seguridad inteligente para todos los hogares.

As I pointed out in a paper and many have commented upon since, Congress in its infinite wisdom did not specify the meaning of "species" when it drafted the Endangered Species Act, presumably because it assumed biologists knew what they were talking about.
