Across mountains and ocean: species delimitation and historical connectivity in Holarctic and Arctic-Alpine wolf spiders (Lycosidae, Pardosa)

Résumé

Abstract Holarctic species offer great opportunities to study biogeography, phylogenetics, taxonomy, and local adaptation. Species that are considered conspecific between the Palearctic Nearctic realms often split into 2 or more when denser sampling molecular markers applied. Similar in complexity but at a finer geographical scale groups having Arctic-Alpine distributions where lineages have complicated demographic histories due glacial dynamics. In both cases, allopatric speciation might not result fast differentiation of morphological characters if environmental conditions isolated areas similar main driver variability is genetic drift. Here, we Pardosa hyperborea (Thorell, 1872) its closest European relatives assess their taxonomic status patterns variability. Based on DNA barcodes genomic data from double-digest restriction site associated sequencing, propose North American populations should be regarded as distinct (P. luteola Emerton,1894, stat. resurr.), possibly consisting several independent lineages. With help D-statistics, population simulations phylogenetic networks analysis, demonstrate historical introgression among group likely explanation for shared fully differentiated species. Our exposes promising model studying processes history parallel sides Atlantic Ocean demonstrates usefulness tools elucidating taxonomy biogeography taxa across broad geographic scales.
