    Abstract One of the most applied tools for documenting cultural variability and for tracing cultural trajectories within the environmental context is eco-cultural niche modeling and its associated methodology. The niche breadth characterization quantitatively evaluates the links between a given adaptive system and ecological constraints, which provides valuable information for archeology. For this purpose, in this study, 10 independent climatic and topographic environmental variables were interpolated, and eco-cultural niche modeling techniques were used to determine whether these differences in geographic distributions and niche breadth are consequences of differences in five Cucuteni–Trypillia groups that flourished in Eastern Europe during the Eneolithic (cal. 5,400/5,300–2,800/2,700 BCE). Our results showed that the eco-cultural niches of Cucuteni–Trypillia groups are significantly overlapping, and the expansion trend of the last two cultural groups (Late Eneolithic–cal. 4,100/4,000–2,800/2,700 BCE) into the northeastern steppe regions was not due to ecological niche differences but rather a result of other cultural factors. Furthermore, we highlighted that the first three Cucuteni–Trypillia groups (Early-to-Middle Eneolithic—cal. 5,400/5,300–4,100/4,000 BCE) had slightly more constrained ecological niches in the mid-Holocene ecosystems than the Late Eneolithic groups. The results have significant implications for understanding the geographical range dynamics and distribution of the last great Chalcolithic society of Old Europe and contribute to the characterization of ecological niches they have exploited during the cultural evolutionary process.

    Abstract Abstract Landscape heterogeneity and fragmentation are key challenges for biodiversity conservation. As Earth’s landscape is increasingly dominated by anthropogenic land use, it is clear that broad-scale systems of nature reserves connected by corridors are needed to enable the dispersal of flora and fauna. The European Union currently supports a continent-wide network of protected areas, the Natura 2000 program, but this program lacks the necessary connectivity component. To examine whether a comprehensive network could be built in order to protect amphibians and reptiles, two taxonomic groups sensitive to environmental changes due to their physiological constrains and low dispersal capacity, we used species’ distribution maps, the sites of community interest (SCIs) in Romania, and landscape resistance rasters. Except Vipera ursinii rakosiensis, all amphibians and reptiles had corridors mapped that, when assembled, provided linkages for up to 27 species. Natura 2000 species were not good candidates for umbrella species as these linkages covered only 17% of the corridors for all species. Important Areas for Connectivity were identified in the Carpathian Mountains and along the Danube River, further confirming these regions as hot spots for biodiversity in Europe, where successful linkages are most likely. In the end, while such corridors may not be created just for amphibians and reptiles, they can easily be incorporated into more complex linkages with corridors for more charismatic species, therefore enhancing the corridors’ value in terms of quality and structure.

    Abstract Abstract The Lindholm rock lizard, Darevskia lindholmi, is the only member of the genus Darevskia whose range is restricted solely to Europe, representing a local endemism found only in the Crimean Mountains. In our study, we investigated the cytochrome b gene (mtDNA) of 101 D. lindholmi sequences from 65 Crimean localities, representing its entire range. We found that D. lindholmi is highly genetically structured, and its range is divided into populations belonging to three mitochondrial lineages. The Lindholm rock lizard populations inhabiting the middle part of the Crimean Mountains (further referred to as the Central lineage) are sharply differentiated from the other two lineages (the Common and the Southwestern lineages), which are present in most of the species range. The genetic distance between the Central lineage and the other two taken together is 4.6%, according to our results, suggesting that the divergence occurred during the Early Pleistocene. The narrowly distributed Southwestern lineage and the widespread Common lineage, on the other hand, are differentiated by 1%. Field observations on the representatives of the main evolutionary groups show that their ecology is also different: the Central lineage is a mesophilic and cold-resistant form, while the other two closely related lineages are more xerophilic and thermophilic. Results of the potential ranges modeling and ecological niche analysis confirm that the genetic lineages occupy different niches of the Crimea. Furthermore, the area of inhabitation of the Central lineage splits the western and eastern parts of the Common lineage range, while the Southwestern lineage is restricted along the coast of the southwestern coast of the peninsula. The long-term co-existence of deeply divergent sister mitochondrial lineages in a relatively small (circa 7,000 km2) isolated mountain system serves as a mesocosm for understanding the speciation process. Our data suggest that the Central lineage warrants further taxonomic investigation.

    Abstract Amphibians and reptiles are among the most threatened animal species in Europe. Because of their legal conservation status, amphibians and reptiles may act as umbrella and flagship species in certain areas. The Rarău-Giumalău Natura 2000 site (ROSCI 0212) is such an area that, despite its conservation status, is still exposed to human activities alterations. In addition, the standard data form of the site mentions only three amphibian species, which is notably below the herpetofauna diversity of the region. Therefore, the aim of this study is to update the existing knowledge on the local herpetofauna. To this end, herpetological field surveys were conducted in the area between May– September, 2015, ten species being identified, as follows: six amphibians (Salamandra salamandra, Lissotriton montandoni, Ichthyosaura alpestris, Bombina variegata, Bufo bufo and Rana temporaria) and four reptiles (Anguis colchica, Lacerta agilis, Zootoca vivipara and Vipera berus). Species distribution is influenced by human activities, among which grazing seems to be the most important. The diversity of herpetofauna is not evenly distributed between the perimeters of the site. The Giumalău perimeter has only six species probably because of a lower habitat diversity compared to the Rarău perimeter. Nine of the identified species are protected by European and national regulations, whereas the standard data form of the site lists only two of them, and one not confirmed by our study. Therefore, the standard data form, a tool for protective management, does not reflect the real situation of the herpetofauna of the site and for this reason, it should be updated.

    Abstract The Danube crested newt, Triturus dobrogicus, was known to be distributed in the Pannonian Basin, along the lower Danube and from the Danube Delta to the Dnepr Delta. Based on the discovery of three specimens in the collection of the “Grigore Antipa” National Museum of Natural History, Bucharest, Romania, we report a new record of Triturus dobrogicus from Lake Durankulak. This location in the north-east of Bulgaria, the Black Sea littoral region, is far outside the previously known range, and therefore establishes a new south-eastern limit for the distribution of this species. The possibility of introgressive hybridization with Triturus karelinii is discussed.

    Abstract The largest size known for the nominate subspecies T. d. dobrogicus is 152mm in a female from Romania, most probably from the Danube Delta. In our paper we present a record female of Triturus dobrogicus from Danube Delta. This female has a total length of 175.5 mm, 7.01% longer than the previous record litearture data for Triturus dobrogicus macrosoma and 15.46% longer than the previous record litearture data for Triturus dobrogicus dobrogicus.

    Abstract Dolichophis caspius is a common snake species in Dobrudja (Tulcea and Constanta counties) and in some areas from south-western Romania (Banat region). However, this species has only been cited in 2 localities in the eastern part of Romania (Moldavia) and has not been recorded since 1937. In the Romanian red data book of vertebrates, the Moldavian populations of Dolichophis caspius are listed as extinct. The present paper provides evidence that the large whip snake still occurs in the Romanian Moldavia by way of 3 live specimens observed in Galaţi county in may 2007.

    Abstract The Aesculapian snake (Zamenis longissimus) is a widespread colubrid species, being present in much of central and southern Europe, with isolated populations occuring as far east as Iran. In Romania, the species is known from most of the country’s regions, although it has been reported from very few areas from the Moldova region (eastern and north–eastern Romania). Here we present three new records for Z. longissimus in Romanian Moldova, including the first record for the species in Botoșani County, the north–easternmost region of Romania.

    Abstract Vincetoxicum sensu lato is a tropical lineage comprising two clades that have reached high northern latitudes. Of the temperate clades, one is restricted to the Far East, the other one (Vincetoxicum s. str. Clade) extends into Europe, but their ranges overlap in Central China and Japan. Three species invasive in North America, V. hirundinaria, V. nigrum and V. rossicum, are members of the Vincetoxicum s. str. Clade. We explore the prerequisites for the range expansion in the Vincetoxicum s. str. Clade performing Bayesian and Maximum Likelihood phylogenetic analyses on sequences of the nuclear internal transcribed spacer (ITS) region, the nuclear external transcribed spacer region (ETS), and five plastid markers. The resulting phylogeny is used to conduct biogeographic analysis using BioGeoBEARS to reconstruct ancestral species ranges. Moreover, we map the known occurrences of two rare characters in Asclepiadoideae, the possession of phenanthroindolizidine alkaloids and reported cases of autogamy onto our phylogeny. Finally, we have conducted ecological niche modelling using Maxent on a total of 220 spatially unique occurrences of nine Vincetoxicum s. str. species spanning more than 4000km along the east–west gradient to learn about the climatic conditions along the presumed migration route. Our results indicate a north-westward migration in Vincetoxicum s. str. along the Asian mountain chains to Europe. Climatic preferences of the nine species sampled are dissimilar, except for the common exposure to at least one month of subfreezing temperatures, indicating a rather wide climatic tolerance for the clade as a whole. The three species invasive in North America belong to the northern Eurasian subclade and show the rare combination of phenanthroindolizidine alkaloids and autogamy.

    Abstract In the researched area we identified 14 amphibian species: (Salamandra salamndra, Triturus vulgaris, Triturus cristatus, Triturus alpestris, Triturus montandoni, Bombina bombina, Bombina variegata, Bufo bufo, Bufo viridis, Pelobates fuscus, Hyla arborea, Rana ridibunda, Rana dalmatina, Rana temporaria) and 8 reptilian species (Lacerta agilis, Lacerta viridis, Zootoca vivipara, Anguis fragilis, Natrix natrix, Elaphe longissima, Coronella austriaca, Vipera berus). Within the region we identified species quoted (Coglniceanu et al. 2000) to have the lowest altitudinal limit of their spreading area at much higher altitudes. The species Triturus montandoni was identified at 320 m altitude at Agârcia and Doamna. Most of the amphibian and reptilian species are not endangered in the researched area.
