The genes of the major histocompatibility complex (MHC) are attractive candidates for investigating the link between adaptive variation and individual fitness. High levels of diversity at the MHC are thought to be the result of parasite-mediated selection and there is growing evidence to support this theory. Most studies, however, target just a single gene(More)
In mammals, males typically have shorter lives than females. This difference is thought to be due to behavioural traits which enhance competitive abilities, and hence male reproductive success, but impair survival. Furthermore, in many species males usually show higher parasite burden than females. Consequently, the intensity of selection for genetic(More)
Fluctuating asymmetry (FA), used as an indicator of developmental stability, has long been hypothesized to be negatively correlated with genetic variability as a consequence of more variable organisms being better suited to buffer developmental pathways against environmental stress. However, it is still a matter of debate if this is due to metabolic(More)
The chamois provides an excellent model for exploring the effect of historical and evolutionary events on diversification. We investigate cytochrome b (cytb) sequences in the 10 recognized subspecies of Rupicapra classified within 2 species: Rupicapra pyrenaica, with the subspecies parva, pyrenaica, and ornata, and Rupicapra rupicapra, with cartusiana,(More)
BACKGROUND Recent studies of selection on mitochondrial (mt) OXPHOS genes suggest adaptation due mainly to environmental variation. In this context, Tunisian hares that display several external phenotypes with phylogenetically rather homogenous gene pool and shallow population structure provide a good precondition to detect positive selection on mt genes(More)
BACKGROUND Jackals are medium-sized canids from the wolf-like clade, exhibiting a unique combination of ancestral morphotypes, broad trophic niches, and close phylogenetic relationships with the wolf and dog. Thus, they represent a potential host of several pathogens with diverse transmission routes. Recently, populations of the Eurasian golden jackal Canis(More)
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) revealing(More)
In Bulgaria, chamois (Rupicapra rupicapra balcanica) are protected by law and it has been recommended to assess their genetic diversity, level of inbreeding, and extent of introgression by Alpine chamois (R. r. rupicapra) that were released in the last century in the Rhodope Mountains. Chamois (n = 81) collected between 2009 and 2013 at the “Izvora State(More)
