Despite continuous historical distribution of the grey wolf (Canis lupus) throughout Eurasia, the species displays considerable morphological differentiation that resulted in delimitation of a number of subspecies. However, these morphological discontinuities are not always consistent with patterns of genetic differentiation. Here we assess genetic distinctiveness of grey wolves from the Caucasus (a region at the border between Europe and West Asia) that have been classified as a distinct subspecies C. l. cubanensis. We analysed their genetic variability based on mtDNA control region, microsatellite loci and genome-wide SNP genotypes (obtained for a subset of the samples), and found similar or higher levels of genetic diversity at all these types of loci as compared with other Eurasian populations. Although we found no evidence for a recent genetic bottleneck, genome-wide linkage disequilibrium patterns suggest a long-term demographic decline in the Caucasian population – a trend consistent with other Eurasian populations. Caucasian wolves share mtDNA haplotypes with both Eastern European and West Asian wolves, suggesting past or ongoing gene flow. Microsatellite data also suggest gene flow between the Caucasus and Eastern Europe. We found evidence for moderate admixture between the Caucasian wolves and domestic dogs, at a level comparable with other Eurasian populations. Taken together, our results show that Caucasian wolves are not genetically isolated from other Eurasian populations, share with them the same demographic trends, and are affected by similar conservation problems.

Abstrakt
The discovery that the most widespread bat in Europe comprises cryptic species, Pipistrellus pipistrellus (Schreber, 1774) (common pipistrelle) and Pipistrellus pygmaeus (Leach, 1825) (soprano pipistrelle), provides a great opportunity to look at the mechanism of species coexistence. Based on eight nuclear microsatellite loci (n = 353), we observed similarities between the species in Poland with respect to heterozygosity, allelic richness, mean relatedness, and inbreeding coefficients. However, pronounced differences in migratory patterns (shown by assignment tests) suggest that P. pygmaeus is the more migratory species. The proportion of bats migrating between colonies differed significantly, with 17.1% and 41.8% individuals of P. pygmaeus and P. pipistrellus, respectively, confidently assigned to colonies of origin. Both species demonstrated a more migratory character in central Europe compared with the populations from the British Isles. Given the cryptic nature of the examined taxa, we also assessed whether they hybridize. Hybridization was confirmed by three methods—one based on genetic distance and two based on Bayesian approaches. The overall hybridization rate, depending on assumed threshold values, ranged from 1.7% to 13.3% for both species. We conclude that the population structuring in these pipistrelles is not homogenous across their range. Moreover, hybridization between them in continental Europe does occur and is not rare. Population genetics study of common (Pipistrellus pipistrellus) and soprano (Pipistrellus pygmaeus) pipistrelle bats from central Europe suggests interspecific hybridization.

Afiliacja MiIZ PAN Tytuł: Skull morphology of two cryptic bat species: Pipistrellus pipistrellus and P. pygmaeus ― a 3D geometric morphometrics approach with landmark reconstruction

Differences in skull morphology between two cryptic species of bat, Pipistrellus pipistrellus (n= 14) and P. pygmaeus (n= 15), originating from Great Britain, were investigated. Four different data sets were analysed: (1) 23 landmarks and (2) 26 landmarks on the dorsal and ventral sides of the cranium, respectively, (3) 49 landmarks on the upper jaw, and (4) 34 landmarks on the labial side of the mandible. For almost all data sets, when compared within sex groups, P. pipistrellus were significantly larger than P. pygmaeus; the biggest difference being observed in the mandible size. Interspecific differences in shape, analysed by Principal Component Analysis and Discriminant Function Analysis (DFA) of the Procrustes superimposed landmarks, were also mostly visible in the mandible, and were related to dietary differences between the species. For example, the longer and more upright canines of P. pipistrellus allow them to pierce harder prey, the bigger molars ease its processing, and the shortened body of the mandible and the more developed coronoid process presumably generate a stronger bite. The shape and size of the mandible proved to be a good characteristic for distinguishing both cryptic taxa. A procedure for estimating missing landmarks for 3D geometric morphometric purposes was created. Our procedure of finding the missing landmarks had no effect on the within-group loss of variation. DFA of data sets with reconstructed versus orginal (but reduced) landmarks yielded similar results (three versus two misclassified specimens in leave-one-out cross-validation).

Traditionally, morphometric data have consisted of distances, angles, or ratios, and have been considered inappropriate for cladistic analyses. Recently, geometric morphometrics, based on homologous landmark point-coordinates, has provided a number of advantages over traditional morphometric data and methods, including the possibility that phylogenetically informative characters and character-states may be extracted and used in cladistic analyses. Using two data sets of 3-dimensional point coordinates collected from skulls of bats, we empirically evaluate this possibility. Partial warps were extracted from the point-coordinate matrix, and these were then re-coded by gap-coding, for use in the cladistic analyses. In the case of samples from Eidolon helvum populations (two mainland localities and four islands in the Gulf of Guinea), analyzing males and females separately, our analyses based on these data were unable to detect consistent phylogeographic patterns among the populations. In the case of samples from plecotine bat species, these analyses produced a consensus cladogram showing considerable concordance with an earlier cladistic analysis by us of this group. In both cases, our results reflect those of earlier studies (based on both morphologic and genetic data), suggesting that the data and analytic techniques described herein may have interesting utility in cladistic analyses.
