    Evolutionary melting pots: a biodiversity hotspot shaped by ring diversifications around the Black Sea in the Eastern tree frog ( Hyla orientalis )

    Molecular Ecology.

    Hotspots of intraspecific genetic diversity, which are of primary importance for the conservation of species, have been associated to glacial refugia, i.e. areas where species survived the Quaternary climatic oscillations. However, the proximate mechanisms generating these hotspots remain an open issue. Hotspots may reflect the long-term persistence of large refugial populations; alternatively, they may result from allopatric differentiation between small and isolated populations, that later admixed. Here we test these two scenarios in a widely distributed species of tree frog, Hyla orientalis, which inhabits Asia Minor and Southeastern Europe. We apply a fine-scale phylogeographic survey, combining fast-evolving mitochondrial and nuclear markers, with a dense sampling throughout the range, as well as ecological niche modeling, to understand what shaped the genetic variation of this species. We documented an important diversity center around the Black Sea, composed of multiple allopatric and/or parapatric diversifications, likely driven by a combination of Pleistocene climatic fluctuations and complex regional topography. Remarkably, this diversification forms a ring around the Black Sea, from the Caucasus through Anatolia and Eastern Europe, with terminal forms coming into contact and partially admixing in Crimea. Our results support the view that glacial refugia generate rather than host genetic diversity, and can also function as evolutionary melting pots of biodiversity. Moreover, we report a new case of ring diversification, triggered by a large, yet cohesive dispersal barrier, a very rare situation in nature. Finally, we emphasize the Black Sea region as an important center of intraspecific diversity in the Palearctic with implications for conservation.

    Tracing the evolutionary history of the mole, Talpa europaea , through mitochondrial DNA phylogeography and species distribution modelling

    Biological Journal of the Linnean Society 114(3) 495-512.

    Our understanding of the effect of Pleistocene climatic changes on the biodiversity of European mammals mostly comes from phylogeographical studies of non-subterranean mammals, whereas the influence of glaciation cycles on subterranean mammals has received little attention. The lack of data raises the question of how and to what extent the current amount and distribution of genetic variation in subterranean mammals is the result of Pleistocene range contractions/expansions. The common mole (Talpa europaea) is a strictly subterranean mammal, widespread across Europe, and represents one of the best candidates for studying the influence of Quaternary climatic oscillation on subterranean mammals. Cytochrome b sequences, as obtained from a sampling covering the majority of the distribution area, were used to evaluate whether Pleistocene climate change influenced the evolution of T. europaea and left a trace in the genetic diversity comparable to that observed in non-subterranean small mammals. Subsequently, we investigated the occurrence of glacial refugia by comparing the results of phylogeographical analysis with species distribution modelling. We found three differentiated mitochondrial DNA lineages: two restricted to Spain and Italy and a third that was widespread across Europe. Phylogenetic inferences and the molecular clock suggest that the Spanish moles represent a highly divergent and ancient lineage, highlighting for the first time the paraphyly of T. europaea. Furthermore, our analyses suggest that the genetic break between the Italian and the European lineages predates the last glacial phase. Historical demography and spatial principal component analysis further suggest that the Last Glacial Maximum left a signature both in the Italian and in the European lineages. Genetic data combined with species distribution models support the presence of at least three putative glacial refugia in southern Europe (France, Balkan Peninsula and Black Sea) during thelast glacial maximum that likely contributed to post-glacial recolonization of Europe. By contrast, the Italian lineage remained trapped in the Italian peninsula and, according to the pattern observed in other subterranean mammals, did not contribute to the recolonization of northern latitudes

    Geographical distribution of Dermacentor marginatus and Dermacentor reticulatus in Europe

    Ticks and Tick-borne Diseases.

    The goal of this paper is to present up-to-date maps depicting the geographical distribution of Dermacentor species in Europe based on georeferenced sampling sites. Therefore, a dataset was compiled, resulting in 1,286 D. marginatus (Sulzer, 1776) and 1,209 D. reticulatus (Fabricius, 1794) locations. Special emphasis is given to the region of the European Alps depicting a presumable climate barrier of the mountains and to overlaps in the distribution of both species as well as on the situation in eastern European countries. For the latter newly described Dermacentor findings comprise 59 locations in Romania and 62 locations in Ukraine. The geographical distributions of both species in Europe range from Portugal to Ukraine (and continue to the east of Kazakhstan). Although it is well known that D. marginatus is adapted to a warmer and drier climate at more southern latitudes and D. reticulatus to a moderately moist climate at more northern latitudes, the distribution limits of both species were not well known. Here, the northern and southern distribution limits for both species in Europe, as determined from the georeferenced database, were specified for D. marginatus by the belt of 33 - 51∘ N latitude and for D. reticulatus by the belt of 41 - 57∘ N latitude. Thus, overlapping species distributions were found between 41∘ N and 51∘ N.

    Sucking herbivore assemblage composition on greenhouse Ficus correlates with host plant leaf architecture

    Arthropod-Plant Interactions.

    Understanding arthropod herbivore selectivity trends towards host plant attributes is essential for predicting plant-associated herbivore assemblage structure. Little is known about such interactions between spontaneous herbivore species and cultivated plants under specific conditions of botanical garden greenhouses. In this study, the taxonomic and functional composition of sucking arthropod herbivore assemblages were correlated with leaf anatomical and surface features of 33 host species of Ficus L. (Moraceae) across four distantly located greenhouse complexes of botanical gardens. The analyses revealed that the species number and abundance of scale insects and their individual families, sessile phloem feeders, total phloem feeders and total herbivores were significantly positively correlated with the thickness of leaf lamina, epidermis and mesophyll, stomatal length and width, and the presence of abaxial multiple epidermis and weak ferruginous non-glandular trichomes. Significant negative correlations were revealed between the same herbivore parameters and the density of glandular trichomes. Heliomorphic leaves supported higher abundance and species richness of sessile phloem feeders compared to sciomorphic ones. The parameters of some phloem and mesophyll feeder taxa also correlated with non-glandular trichome length and density, type of trichomes and epicuticular wax layer, and the presence of calcium oxalate crystals in the epidermis. Results of the study suggest that the leaf architecture-related herbivory trends under greenhouse conditions are similar to those occurring in natural ecosystems when considering the functional significance of particular leaf traits, and remain relevant at the scale of particular plant taxa with disregard of spatial factor.

    Lamina shape variability in species of the genus Ficus L. in different ecological conditions

    Contemporary Problems of Ecology 7(2) 210-220.

    The morphological variability of the leaf apparatus in response to different levels of light is deter? mined not only by the available solar irradiance, but also by a complex of preadaptations to some other envi? ronmental factors. Data on the influences of climatic characteristics for natural ranges on manifested differ? ences in leaves of light and shadow allocations remain insufficient. This paper investigates the differences in lamina shapes among fifteen species of the genus Ficus L. Relationships between the determined plasticity and climatic conditions of the native habitats of species have been ascertained. Positive dependences on the annual cycle amplitude and amount of precipitation, as well as temperature seasonality, have been revealed.

    Host preference of herbivorous arthropods feeding on Ficus (Moraceae) grown ex situ in Ukraine

    Environmental and Experimental Biology 205-214.

    Different plant taxa are known to be selectively preferred by particular herbivorous arthropod species. The goal of our study was to determine to what extent Ficus-feeding herbivores may display host preference with respect to plant infrageneric taxa under greenhouse conditions of a botanical garden. Using conventional methods for arthropod sampling in greenhouses, it was shown that the abundance and species richness of sucking herbivores on Ficus greatly depended on the taxonomic position of both herbivores and their host-plants. Herbivores of all found taxa tended to choose plants of subgenus Urostigma for feeding, while those of the subgenera Synoecia and Sycidium were mostly ignored by them. Ficus plants in general seemed to be most preferred by herbivores of the families Pseudococcidae and Tetranychidae among all the species found. This finding may potentially be useful in prediction of herbivore assemblage structure and feeding behaviour in Ficus-containing plant communities. Key

    Radically different phylogeographies and patterns of genetic variation in two European brown frogs, genus Rana

    Molecular Phylogenetics and Evolution 68(3) 657-70.

    We reconstruct range-wide phylogeographies of two widespread and largely co-occurring Western Palearctic frogs, Rana temporaria and R. dalmatina. Based on tissue or saliva samples of over 1000 individuals, we compare a variety of genetic marker systems, including mitochondrial DNA, single-copy protein-coding nuclear genes, microsatellite loci, and single nucleotide polymorphisms (SNPs) of transcriptomes of both species. The two focal species differ radically in their phylogeographic structure, with R. temporaria being strongly variable among and within populations, and R. dalmatina homogeneous across Europe with a single strongly differentiated population in southern Italy. These differences were observed across the various markers studied, including microsatellites and SNP density, but especially in protein-coding nuclear genes where R. dalmatina had extremely low heterozygosity values across its range, including potential refugial areas. On the contrary, R. temporaria had comparably high range-wide values, including many areas of probable postglacial colonization. A phylogeny of R. temporaria based on various concatenated mtDNA genes revealed that two haplotype clades endemic to Iberia form a paraphyletic group at the base of the cladogram, and all other haplotypes form a monophyletic group, in agreement with an Iberian origin of the species. Demographic analysis suggests that R. temporaria and R. dalmatina have genealogies of roughly the same time to coalescence (TMRCA ~3.5 mya for both species), but R. temporaria might have been characterized by larger ancestral and current effective population sizes than R. dalmatina. The high genetic variation in R. temporaria can therefore be explained by its early range expansion out of Iberia, with subsequent cycles of differentiation in cryptic glacial refugial areas followed by admixture, while the range expansion of R. dalmatina into central Europe is a probably more recent event.

    Sampling bias in geographic and environmental space and its effect on the predictive power of species distribution models

    Systematics and Biodiversity(3) 305-315.

    Despite ever-growing popularity of species distribution models (SDM), their performance under conditions of spatially biased data has rarely been studied in detail. Here we explore the effect of a known spatial bias on the predictive ability of Maxent models, using five species of the genus Asplenium with variable reproductive modes. The models were trained and tested on western and central European presence-only distributional data, first with random background and then with target-group background. Then we tested the models on an independent Ukrainian dataset of the same species, using the area under the curve (AUC) value as test statistic.We carried out a principal components analysis (PCA) on the collection localities of the individual species to explore the properties of their ecological niches. In all but one species, spatial bias in the distributional data resulted in poor performance of theMaxent models (trained on the European dataset and tested on the Ukrainian dataset). In all species correction for sampling bias resulted in significantly wider predicted climatic niches. Based on the results of the PCA, spatial bias resulted in environmental bias of variable degree.We argue that species reproductive biology should be taken into account when distributional data are analysed in terms of their suitability for species distribution modelling. The reported results will inform biodiversity conservation assessments, particularly those using data from natural history collections.

    Allelic variation at high-molecular-weight glutenin subunit loci in Aegilops biuncialis Vis.

    Russian Journal of Genetics 47(9) 1078-1083.

    Alleles at the high molecular weight glutenin subunit loci GluU1 and GluMb1 were analyzed in the tetraploid species Aegilops biuncialis (UUMbMb). The material for the investigation included the collection of 39 accessions of Ae. biuncialis from Ukraine (the Crimea), one Hellenic accession, one accession of unknown origin, F2 seeds from different crosses, as well as samples from natural populations from the Crimea. Ae. umbellulata and Ae. comosa accessions were used to allocate components of the HMW glutenin subunit patterns of Ae. biuncialis to U or Mb genomes. Eight alleles were identified at the GluU1 locus and ten alleles were revealed at the GluMb1 locus. Among alleles at the GluMb1 locus of Ae. biuncialis there were two alleles controlling the ytype subunit only and one allele encoding the xsubunit only
