The European roe deer (Capreolus capreolus) is one of the most numerous and widespread ungulate species in Europe, which has complicated the assessment of its genetic diversity on a range-wide scale. In this study, we present the mitochondrial DNA control region (mtDNA CR) genetic diversity and population structure of roe deer in Europe based on th...
Article
The genes of the major histocompatibility complex (MHC) are among the best candidates for studying adaptive variation driven often by pathogen-mediated selection. However, diversity of these genes might be differently shaped by selective and non-selective evolutionary mechanisms. In this study, we assessed the spatial distribution of MHC class II D...

Background Animal mitochondria play a central role in energy production in the cells through the oxidative phosphorylation (OXPHOS) pathway. Recent studies of selection on different mitochondrial OXPHOS genes have revealed the adaptive implications of amino acid changes in these subunits. In hares, climatic variation and/or introgression were sugge...

Background: The aim of the study was to use hybrid populations as well as island populations of the European brown hare (Lepus europaeus) to explore the effect of evolutionary events, such as the post-deglaciation translocations, spontaneous and human-mediated, local adaptation and the genetic drift in the shaping of the phylogeographic patterns o...
Article
Full-text available
Previous studies in hares and jackrabbits have indicated that positive selection has shaped the genetic diversity of mitochondrial genes involved in oxidative phosphorylation, which may affect cellular energy production and cause regional adaptation to different environmental (climatic) pressures. In the present study, we sequenced the NADH dehydro...
Article
Wild boar populations are strongly increasing across Europe. Although details of population dynamics and re- productive potential are known in this species, our knowledge about the social structure and a possible impact of hunting on this structure is poorly understood. Here we investigated the grouping behaviour of yearling wild boar females under...

Local colonies of European ground squirrels may fluctuate or decline rapidly and severely in their census size. Respective risk factors may vary locally and include habitat and weather characteristics or human related factors (e.g., measures connected to the protection status of colonies); they possibly can trigger severe density fluctuations. In t...
Poster
European ground squirrels were collected as road kills in the province of Lower Austria. During necropsy in 10 animals several tapeworm cysts were found. In 6 animals the cysts were in/close to the liver, 1 was attached to the sternum, 1 free in the thorax, 1 was found in the brain, and in 2 other cases cysts were found free in the abdomen. In 9 of...

In natural populations, allelic diversity of the major histocompatibility complex (MHC) is commonly interpreted as resulting from positive selection in varying spatiotemporal pathogenic landscapes. Composite pathogenic landscape data are, however, rarely available. We studied the spatial distribution of allelic diversity at two MHC class II loci (D...
Article
Toll-like receptors (TLRs) are a major group of proteins that recognize molecular components of infectious agents, known as pathogen associated molecular patterns (PAMPs). The structure of these genes is similar and characterized by the presence of an ectodomain, a signal transmembrane segment and a highly conserved cytoplasmic domain. The latter d...

North African hares are currently included in cape hares, Lepus capensis sensu lato, a taxon that may be considered a superspecies or a complex of closely related species. The existing molecular data, however, are not unequivocal, with mtDNA control region sequences suggesting a separate species status and nuclear loci (allozymes, microsatellites)...
Conference Paper
Two European ground squirrel road kills originating from the Province of Lower Austria were submitted for post-mortem examination in 2015. Both were male and classified as adult. Apart from haemorrhages presumably caused by traffic, both animals showed pathological alterations in the lungs. The lungs of the first animal appeared multifocally dystel...

Microsatellites are regularly used to identify individuals, investigate population structures, or reveal relatedness and parenthood. Here we analysed a set of 17 microsatellite markers commonly used for such analyses in the wild boar (Sus scrofa). Specifically, we considered genotypes of 123 females and 24 males originating from four different loca...
Conference Paper
Wild boar (Sus scrofa) are increasingly considered invasive to metropolitan, peri-urban, and suburban areas, raising various conflicts with human interests. Moreover, they may transmit infectious diseases to humans, their pets, and livestock. Successful control of wild boar in such areas depends in part on identifying source populations, immigratio...

Accumulation of heavy metals viz; Cd, Cr and Pb was investigated in Indian hares (Lepus nigricollis) collected from different areas of Pakistan. Three organs viz; kidney, liver and muscles of 15 female, 13 male and three juvenile individuals were studied to find out the level of Cd, Cr and Pb accumulation, and distribution among sex and age groups...
Article
Genetic introgression from a resident species into an invading close relative can result from repeated hybridisation along the invasion front and/or allele surfing on the expansion wave. Cases where the phenomenon is massive and systematic, such as for hares (genus Lepus) in Iberia, would be best explained by recurrent hybridisation but this is dif...

The objective of this research was to attempt to differentiate brown hare populations from different regions in Turkey that are separated by potential geographic barriers (Bosphorus, Dardanelles, “Anatolian Diagonal”) using a landmarkbased geometric morphometric approach based on 71 adult individuals.
Article
Recently, many new (extant) mammal species have been named, mostly by raising subspecies to species rank. This is primarily a consequence of the phylogenetic species concept (PSC) that has become very popular over the last few decades. We highlight several cases of splitting and argue that much of this taxonomic inflation is artificial due to short...

Article
Hares (Lepus capensis Linnaeus 1758) were probably introduced into Sardinia in historical times. Previous studies indicated North Africa as the most likely source area but did not exclude the occurrence of hybridization events with continental brown hares (L. europaeus Pallas 1778) perhaps introduced for hunting purposes. We implemented both morpho...
