On the origin of mongrels: evolutionary history of free-breeding dogs in Eurasia

Tomasz Grzybowski

Although a large part of the global domestic dog population is free-ranging and free-breeding, knowledge of genetic diversity in these free-breeding dogs (FBDs) and their ancestry relations to pure-breed dogs is limited, and the indigenous status of FBDs in Asia is still uncertain. We analyse genome-wide SNP variability of FBDs across Eurasia, and show that they display weak genetic structure and are genetically distinct from pure-breed dogs rather than constituting an admixture of breeds. Our results suggest that modern European breeds originated locally from European FBDs. East Asian and Arctic breeds show closest affinity to East Asian FBDs, and they both represent the earliest branching lineages in the phylogeny of extant Eurasian dogs. Our biogeographic reconstruction of ancestral distributions indicates a gradual westward expansion of East Asian indigenous dogs to the Middle East and Europe through Central and West Asia, providing evidence for a major expansion that shaped the patterns of genetic differentiation in modern dogs. This expansion was probably secondary and could have led to the replacement of earlier resident populations in Western Eurasia. This could explain why earlier studies based on modern DNA suggest East Asia as the region of dog origin, while ancient DNA and archaeological data point to Western Eurasia.

The consequences of vegetation degradation under the influence of anthropogenic activity in the territory of the Zarafshan Range (Western Tajikistan)

We examine the richness and diversity of the flora of the Zarafshan Range in Tajikistan by using endemic species as an example. We determined the character and type of ecosystems, and the presence of endemics in a particular biotope. A potential threat to the unique ecosystems is brought by the cutting down of shrubs and juniper vegetation, unauthorized removal of rare plants, gathering of edible plants as well as waterlogging of the territory.

First cave records for Palearctic burrower bugs (Hemiptera: Heteroptera: Cydnidae) from Tajikistan, with a checklist of the World Cydnidae associated with caves

Grzegorz Kłys

Jerzy A. Lis

Species of the family Cydnidae (known as the “burrower bugs”) live usually on or in the ground; sometimes they even burrow deep into the soil (e.g., Froeschner 1960; Schaefer 2003; Linnavuori 1993; Lis 1994, Lis et al. 2000). However, data on burrower bugs associated with caves and their environment are very rare; only ten species of three Cydnidae subfamilies were hitherto recorded from this type of habitat (see the checklist at the end of this paper).

Anatomical and Morphological Structure of the Skull of a Juvenile Specimen of Myotis myotis (Chiroptera: Vespertilionidae)

Grzegorz Kłys

Elżbieta Koenig

Few studies analyze the morphology and anatomy of the bat skull, and most of them are incomplete. Some of the difficulties stem from the fact that, in the representatives of the order Chiroptera, the interosseous sutures disappear by fusing together before active flight begins, which takes place over only a few months. This study presents a detailed morphological and anatomical description of the skull of a juvenile specimen of Myotis myotis (Borkhausen, 1797). Juvenile skulls are difficult to preserve and often incomplete. Previously inconsistent terminology related to bones, sutures, and other cranial structures was unified, which will provide insight on the distribution of each structure in both juvenile and adult specimens to be investigated. The description fill in the gaps in knowledge about the cranial structures of Myotis myotis and the representatives of the family Vespertilionidae. This will allow for precise descriptions of the skulls of bats.
