Abstract Patterns of interspecific introgression may vary geographically, and the distribution introgressed variants can yield insight into historical dynamics genetic interactions between hybridizing species. Urodele amphibians, often characterized by limited mobility, deep intraspecific structuring vulnerability to climatic changes, constitute suitable models for such inferences. Here, we combine an extensive survey mitochondrial (mt DNA ) nuclear (15 microsatellites) genomes in C...
Roadkill is widely recognized as one of the primary negative effects roads on many wildlife species and also has socioeconomic impacts when they result in accidents. A comprehensive dataset roadkill locations essential to evaluate factors contributing risk enhance our comprehension its impact populations dimensions. We undertook a compilation records, encompassing both published unpublished data gathered from road surveys or opportunistic sources. GLOBAL ROADKILL DATA includes 208,570...
Dolichophis caspius is frequently affected by road mortality, with many victims recorded also in Romania. Although some regions the country have a presumptive high risk of there no certain data from all regions. In 2021 and 2024, we analyzed this species’ mortality at its northern distribution range limit (lower Olt River valley, southern Romania). We identified 66 road-killed D. over course eight days. Most (62.12%) were juveniles. The number juveniles consequence road`s features, which...
Abstract We examined the diet of Hyla arborea over its entire activity period (March to late September, 2004), and analysed a total 585 adult samples. From stomach contents we identified plant remains, shed-skin fragments, animals. 2976 prey items, almost all which originated from terrestrial environment. Adult araneans coleopterans were most abundant items in studied tree frogs. Some become certain parts year (e.g. Homoptera, Lepidoptera larvae, Trichoptera). The dietary diversity index is...
In the Carei Plain natural reserve we identified 15 terrestrial isopod species: Haplophthalmus mengii, danicus, Hyloniscus riparius, transsylvanicus, Plathyarthrus hoffmannseggii, Cylisticus convexus, Porcellionides pruinosus, Protracheoniscus politus, Trachelipus arcuatus, nodulosus, rathkii, Porcellium collicola, Porcellio scaber, Armadillidium vulgare and versicolor. The highest species diversity is found in wetlands, while lowest plantations forests. On Plain, there are some isopods that...
Macrozoobenthic invertebrate assemblages are a very important component of water ecosystems that reflect quality.The evaluation these in the Jiului Corridor Natura 2000 site can highlight natural value aquatic biodiversity.Thus, our study aimed to analyze seven streams from Jiu point view macrozoobenthic assemblages' structure.The samples were collected June 2020.Also, we measured most physicochemical parameters water.In sample sites, found number 31 taxa.There differences between sites...
Herein we present 2 new localities for Dolichophis caspius in southern Romania: Drăgăneşti Olt and Căscioarele.
The diet of some populations Lissotriton montandoni from north-western Romania is composed prey belonging to 20 categories. food components the Carpathian newts are similar those other species newts. Most aquatic animals, but terrestrial also has a high percentage abundance. consumed categories common in newts' habitats as well, natural ponds item with highest abundance not most frequent one habitat. Thus, although basically opportunistic predators, they still display certain trophic selectivity.
Terrestrial isopods from warm shores neighboring the thermal waters western Romania remain active in winter. This phenomenon is registered 35 habitats, affecting 12 species (Hyloniscus transsilvanicus, H. riparius, Haplophthalmus danicus, Trichoniscus sp., Androniscus roseus, Cylisticus convexus, Protracheoniscus politus, Trachelipus nodulosus, T. rathkii, Porcellio dilatatus, Armadillidium vulgare, A. versicolor), most common being nodulosus. Females with a marsupium were observed cold...
In September 2011 we identified a killed specimen of Eryx jaculus on the road between towns Turnu Magurele and Corabia, in southern Romania. This seems to be first record species north Danube. Although surprising, identification E. area is interpreted light presence other herpetofauna Danube floodplain with similar ecological requirements, reaching here their northern distribution limit. Survival appears favoured by existence some protected areas region.
The importance of artificial underground habitats for biodiversity is becoming more and apparent. Abandoned railway tunnels are artificial, considerable biodiversity, including several species conservation concern. We surveyed 16 abandoned in 2014 Romania the following faunal groups: amphibians, terrestrial isopods, spiders. Amphibians occurred primarily flooded tunnels, isopods were present moist with woody debris, while spiders widespread exhibited greatest diversity tunnels. Some...
In the winter of 2010/2011 we identified 6 new thermal habitats, with winter-active amphibian populations in Banat region south-western Romania. The diversity species was small, only 2 were observed: Bombina bombina and Pelophylax ridibundus. waters high flow temperature, number winteractive frogs reached several hundred. All habitats are artificial, being subjected to a powerful anthropogenic pressure.
Two new populations of the European mudminnow, Umbra krameri Walbaum, 1792, were encountered in Banat and Oltenia regions, south-western Romania, within 2014–2017. The mudminnows captured with a hand net used normally for frogs. This is first record this species Banat. In U. was region where it considered extinct. both areas present its characteristic habitats, i.e., small water bodies dense aquatic vegetation. subject to human pressure areas, but more severe Banat, agriculture...
The feeding of four amphibian species (Triturus cristatus, Lissotriton vulgaris, Bombina variegata, Pelophylax ridibundus) was studied in 2011, south–western Romania. diet the newts uniform and mostly composed aquatic preys anurans more diversified, comprising prey taxa, terrestrial. trophic niches two newt overlapped highly but differed from those anurans. one another. differences among species’ diets were determined by use different resources, originating environments, their sizes. newts’...
Our study refers for the first time to knowledge of trophic spectrum some Rana ridibunda populations, active during winter in three thermal habitats from western Romania. The populations feed all winter, but as weather gets colder, one could notice a pronounced decrease number prey taxa consumed and average preys, along with an increase empty stomachs, stomachs containing only vegetals. Most preys identified belong terrestrial taxa, aquatic become majoritary months temperatures below zero....
