The colonization of Europe by the freshwater crustacean Asellus aquaticus (Crustacea: Isopoda) proceeded from ancient refugia and was directed by habitat connectivity
The colonization history of the ubiquitous aquatic isopod crustacean Asellus aquaticus was assessed using mitochondrial COI and a variable part of nuclear 28S rDNA sequences, and isolation seemed to be strong enough to prevent homogenization of the rRNA gene family.
Diverse molecular data demonstrate that commercially available medicinal leeches are not Hirudo medicinalis
It is shown, with mitochondrial sequences and nuclear microsatellites, that there are at least three species of European medicinal leech, and that leeches marketed as H. medicinalis are actually Hirudo verbana.
Phylogeography of a subterranean amphipod reveals cryptic diversity and dynamic evolution in extreme environments
It is argued that future analyses of evolution and biogeography in subsurface, or more generally in extreme environments, should consider dispersal ability as an evolving trait and morphology as a potentially biased marker.
Global diversity of leeches (Hirudinea) in freshwater
Leeches (Hirudinea) constitute a relatively small monophyletic group of highly specialized annelids, but may play important roles as invertebrate predators in freshwater, while others are infamous
Molecular phylogeny of leeches: Congruence of nuclear and mitochondrial rDNA data sets and the origin of bloodsucking
The monophyly of the families Erpobdellidae, Piscicolidae, and Glossiphoniidae, the suborders ErpOBdelliformes and Hirudiniformes, and the order Arhyn-chobdellsida have been confirmed by parsimony and maximum likelihood phylogenetic analysis of separate and combined data sets.
The importance of naming cryptic species and the conservation of endemic subterranean amphipods
The South European cryptic complex of the subterranean amphipod Niphargus stygius sensu lato is scrutinized, showing that it consists of 15 parapatric and sympatric species, which are described using molecular diagnoses and are as evolutionarily distinct as average nominal species of the same genus.
