Over eight kilobases (kb) of sequence from eight genes including two mitochondrial loci, Cyt b and 12S, and six nuclear loci, B2m , Zp3 , Tcp1, Sry, Smcx and Smcy , were used to investigate phylogenetic relationships among 11 taxa representing eight species within the rodent genus Mus . Particular attention was given to discerning relationships among species within the subgenus Mus including me...

This study details the phylogeographic pattern of the white-throated dipper (Cinclus cinclus), a Palearctic, temperate, passerine bird that is exclusively associated with flowing water. Our results reveal a complex phylogeographic structure with at least five distinct lineages for the Western Palearctic region. As for many species of the Western Palearctic fauna and flora, this genetic structur...

Abstract In the literature, 114 species of arthropods associated to Microtus oeconomus have been reported in entire area their occurrence. There are eight hard ticks, 52 gamasid and chigger mites, 47 fleas seven sucking lice. general, dominant parasites Palearctic Nearctic root vole populations either western or species. The analysis geographical range occurrence indicates that most them occur ...

Drosophila melanogaster is an important model organism in evolutionary genetics, yet little is known about the population structure and the demographic history of this species within sub-Saharan Africa, which is thought to contain its ancestral range. We surveyed nucleotide variation at four 1-kb fragments in 240 individual lines representing 21 sub-Saharan and 4 Palearctic population samples o...

We examined the presence of possible Recent refugia of Pleistocene mammalian faunas in Eurasia by analysing regional differences in the mammalian species composition, occurrence and extinction rates between Recent and Last Glacial faunas. Our analyses revealed that most of the widespread Last Glacial species have survived in the central Palearctic continental regions, most prominently in Altai-...

A diverse Diptera assemblage, dominated by the family Chloropidae, is associated with common reed (Phragmites australis (Cav.) Trin. ex Steudel, Poaceae) in the Palearctic region (Tewksbury et al. 2002). Although P. australis has long been present in North America, many of its associated Chloropidae have remained restricted to the Palearctic. The best-known chloropid associates of Phragmites ar...

Little is known of the biology and diversity of the environmental model genus Daphnia beyond the Nearctic and western Palearctic. Here, we describe Daphnia sinevi sp. nov., a species superficially similar to Daphnia curvirostris Eylmann, 1878, from the Far East of Russia. We estimated its phylogenetic position in the subgenus Daphnia s. str. with a rapidly evolving mitochondrial protein coding ...

There is an error in the fifth sentence of the first paragraph of the Results section. The correct sentence is: Pigeons and doves (Columbidae) sampled in this study were primarily parasitized byHaemoproteus parasites in the subgenus Haemoproteus (unpublished molecular analyses). However, one individual (African olive pigeon) was parasitized by a novelHaemoproteus lineage that was most closely r...

The horse fly fauna (Diptera: Tabanidae) of Jordan is, after Israel, the richest in the Levant, with 24 known species. During the 20-year project "The Ecology and Zoogeography of the Lepidoptera of the Near East," we regularly collected blood-feeding flies, resulting in 11 additional species of Tabanidae for Jordan. The new records are: Atylotus quadrifarius (Loew, 1874), Chrysops caecutiens (L...

Combining phylogeographic data from mitochondrial DNA (mtDNA) of Nearctic and Palearctic freshwater and anadromous fishes, we used a comparative approach to assess the influence of historical events on evolutionary patterns and processes in regional fish faunas. Specifically, we (i) determined whether regional faunas differentially affected by Pleistocene glaciations show predictable difference...
