Northern Eurasia is extensive and includes terrestrial aquatic ecosystems that cover several natural zones access to the seas of three oceans. As a result, it has been invaded by numerous invasive alien species (IAS) over large temporal spatial scales. The purpose this research was assess invasion trends construct distribution models for Russian TOP-100 most dangerous IAS. Environmentally suitable regions IAS were established based on attribute databases, datasets 169,709 occurrence records...
Caucasian rock lizards of the genus Darevskia are unique taxa, including both bisexual and parthenogenetic species. The species have originated as a result natural hybridisation between females males different involved in interspecific called parental. However, sympatric zones (SZ) unisexual Caucasus still poorly studied, although they very important for understanding role hybrid individuals origin reticulate evolution. This paper presents location SZs their parental Armenia adjacent...
The striped field mouse (Apodemus agrarius Pallas, 1771) is a widespread species in Northern Eurasia. It damages crops and carries zoonotic pathogens. Its current future range expansion under climate change may negatively affect public health the economy, warranting further research to understand ecological invasive characteristics of species. In our study, we used seven algorithms (GLM, GAM, GBS, FDA, RF, ANN, MaxEnt) develop robust ensemble distribution models (eSDMs) (1970-2000)...
Among vertebrates, true parthenogenesis is known only in reptiles. Parthenogenetic lizards of the genus Darevskia emerged as a result hybridization bisexual parental species. However, uncertainty remains about mechanisms co-existence these forms. The geographical hypothesis suggests that unisexual forms can co-exist with their species “marginal” habitats. Our goal to investigate influence environmental factors on formation ecological niches and distribution lizards. For this reason, we...
The all-female Caucasian rock lizard Darevskia rostombekowi and other unisexual species of this genus reproduce normally via true parthenogenesis. Typically, diploid parthenogenetic reptiles exhibit some amount clonal diversity. However, allozyme data from D. have suggested that consists a single clone. Herein, we test hypothesis by evaluating variation at three variable microsatellite loci for 42 specimens four populations in Armenia. Analyses based on nucleotide polymorphisms each locus...
Abstract Parthenogenetic species of Caucasian rock lizards the genus Darevksia are important evidence for reticulate evolution and speciation by hybridization in vertebrates. Female‐only lineages formed through interspecific have been discovered many groups. Nevertheless, critical mechanisms oogenesis specifics meiosis that provide long‐term stability parthenogenetic still unknown. Here we report cytogenetic characteristics somatic karyotypes meiotic prophase I nuclei diploid Darevskia...
Open access to occurrence records of the most dangerous invasive species in a standardised format have important potential applications for ecological research and management, including assessment invasion risks, formulation preventative management plans context global climate land use changes short long perspective. The striped field mouse (Apodemus agrarius Pallas, 1771) is common temperate latitudes Palaearctic. Due changes, several waves expansion range this been observed or inferred. By...
The potential ranges of three near-water mammals included in the list 100 most dangerous invasive species Russia (Сanadian beaver, Muskrat, American mink) were presented. Maps suitable habitats created by ensemble modeling spatial distribution (eSDM) based on global occurrence records native and range, bioclimatic variables characterizing current climate. efficiency construction models as compared to individual (iSDM) is evaluated. results analysis consequences invasions are presented...
The concept of ecological niches plays an important role in predicting the potential distribution species invasive range and developing invasion management strategies. To test hypothesis, we used models 100 most dangerous Russia. Our results show that occupy a position similar to native space predictor variables there is very limited expansion niches. generally support niche conservatism hypothesis. We also found exceptional cases rejection this key mechanisms governing persistence increase...
During field survey in 2018, we recorded Armenia the occurrences of parthenogenetic lizard Darevskia armeniaca and its “paternal” bisexual species D. valentini . Based on our new data records taken from publications museums, update distribution maps these species. The expand geographical boundaries sympatric habitats provide additional for understanding mechanisms reticulate evolution hybrid speciation.
Abstract — The results of the analysis genetic variability parthenogenetic Darevskia rostombekowi (Darevsky, 1957) species using four microsatellite-containing loci are presented. Based on 118 records with geographical coordinates presence this in Transcaucasia, maps potential range were created. structure populations demonstrated that despite established multiclonality (seven clonal lines populations), D. was formed as a result single act hybridization between closely related bisexual...
