Molecular systematics of the Pardosa groenlandica species complex (Araneae: Lycosidae): large sample sizes fail to find monophyletic species
Published online by Cambridge University Press: 23 January 2015
Abstract
Relationships within the Pardosa groenlandica species complex (sensu Slowik and Sikes 2013) were analysed to test two competing hypotheses – the species complex consists of either four or seven species. We conducted a partitioned Bayesian analyses of the mitochondrial gene COI and the nuclear genes ITS1, 5.8S, and ITS2. These genes provided a dataset composed of 1874 nucleotides each from 144 specimens. Additional analyses included application of the DNA barcoding protocol and a phylogeographic study of a subset of specimens. Analyses found no support for either hypothesis and only one species was found monophyletic in a subset of analyses. Mitochondrial DNA yielded clades discordant with geography. Species in the P. groenlandica species complex show various amounts of genetic support, with a general lack of agreement between genetics and morphology for species boundaries.
