Adinopsis nippon sp. n. is described from Japan and represents the first discovery of the genus Adinopsis in the temperate zone of the East Palearctic region. It is closely related to A. myllaenoides (Kraatz) known from North and South America and is placed in the myllaenoides species group. An annotated catalogue of the world species of Adinopsis is presented.

Mountains host greater avian diversity than lowlands at the same latitude due to their greater diversity of habitats stratified along an elevation gradient. Here we test whether this greater ecological heterogeneity promotes sympatric speciation. We selected accentors (Prunellidae), an avian family associated with mountains of the Palearctic, as a model system. Accentors differ in their habitat...

The genus Eremocoris Fieber is represented by 43 species, and three subspecies, 14 and 3 are Palearctic, 5 Oriental, 3 Afrotropical and 21 Nearctic. 14 species are recorded in Mexico.  This contribution contains descriptions and illustrations of the adult and all immature stages of Eremocoris juquilianus sp. nov. and notes on its biology, habitat, and distribution in Mexico.

There are 14 species of marmots distributed across the Holarctic, and despite extensive systematic study, their phylogenetic relationships remain largely unresolved. In particular, comprehensive studies have been lacking. A well-supported phylogeny is needed to place the numerous ecological and behavioral studies on marmots in an evolutionary context. To address this situation, we obtained comp...

Providing an underutilized source of information for paleoenvironmental reconstructions, birds are rarely used to infer paleoenvironments despite their well-known ecology and extensive Quaternary fossil record. Here, we use the avian fossil record to investigate how Western Palearctic bird assemblages and species ranges have changed across the latter part of the Pleistocene, with focus on the l...

New stands of Paramecium dodecaurelia were found in Russia, Ukraine, Kazahstan, Poland, and Tenerife. Molecular studies (RAPD and sequencing of LSU rRNA and CO1 mtDNA gene fragments) of P. dodecaurelia strains depicted intraspecific polymorphism within the species, revealed as distinct differences between strains from the USA in comparison with strains from different regions of the Palearctic.
