Conservation biologists assign population distinctiveness by classifying populations as
evolutionarily significant units (ESUs). Historically, this classification has included ecological …

▪ Abstract Species are routinely used as fundamental units of analysis in biogeography,
ecology, macroevolution, and conservation biology. A large literature focuses on defining …

The species problem has triggered the publication of an almost infinite number of theoretical
and practical studies, including quite a number of books. I should, therefore, perhaps briefly …

Phylogeography is a discipline concerned with various relationships between gene
genealogies—phylogenetics—and geography. The word “phylogeography” was coined in …

A simple method is described for designing primer sets that can amplify specific protein-
encoding sequences in a wide variety of filamentous ascomycetes. Using this technique, we …

Genetic structuring of plant populations is strongly influenced by both common ancestry and
current patterns of interpopulation genetic exchange. The interaction of these two forces is …

The literature about species concepts might be larger than that about any other subject in
evolutionary biology, but the issue of empirically testing species boundaries has been given …

Avec presque 40 000 espèces, les araignées constituent un modèle important pour l'étude
de la vie sociale, des systèmes d'accouplement et du dimorphisme sexuel. Cependant, la …

I analyze a number of widespread misconceptions concerning species. The species
category, defined by a concept, denotes the rank of a species taxon in the Linnaean …

While studies of phylogeography and speciation in the past have largely focused on the
documentation or detection of significant patterns of population genetic structure, the …
