Abstract Microplastic pollution is a significant global environmental issue, and impacts span from individual organisms to the entire ecosystems. This study investigated properties of microplastics in amphibian larvae, shedding light on their interactions potential ecological consequences. We examined extracted larvae 10 taxa, sampled sites experiencing different levels human impact. Our findings revealed predominance blue fibres, each comprising 53% total larvae. fibres were also notably...

Microplastics, pervasive environmental pollutants, are found across various ecosystems, including small inland water bodies. They reported in different media, yet little is known about the mutual relationships of microplastics' properties components Here, having extracted and analyzed these particles from water, sediment, amphibian larvae 23 sites, we test within-site similarities regarding shape (morphological type), color, chemical composition (polymer type). We also provide a brief...

Amphibians are vital components of global biodiversity and fulfil diverse ecological roles, including insect population control serving as environmental health indicators. However, there is a concerning decline in amphibian populations globally due to factors such habitat loss, climate change, emerging diseases. Concurrently, the issue microplastic pollution has gained prominence because its potential harm aquatic ecosystems. Microplastics, derived from various sources, endanger organisms,...

Abstract The slow-worm lizards ( Anguis ) comprise five species occurring throughout most of the Western Palearctic. Although these are relatively uniform morphologically – with exception A. cephallonica , which exhibits a quite unique morphology they genetically deeply divergent. Here, we provide detailed distribution maps for each and discuss their biogeography conservation based on updated genetic data robust database. We pay particular attention to so called ‘grey zone’, typically...

Five slow-worm species are distributed in the Palearctic region. Two species, Anguis fragilis and A. colchica , native to Central Europe, where only limited information on phylogeography of genus exists. Here, we examined situation Poland surrounding regions, a mitochondrial contact zone between is expected. We used new DNA sequences available published data from Europe northern Balkans.

Abstract It is postulated that melanism in ectotherms adaptive by enhancing thermoregulation, subsequent resource acquisition, and growth. Such effects may differ between the sexes as a result of differential costs self-maintenance reproduction, but empirical support for sex-specific consequences remains inconsistent. We studied on body size sex ratio population European grass snake ( Natrix natrix ) SE Poland also carried out systematic review literature terrestrial snakes. Melanistic...

Abstract The fire salamander Salamandra salamandra is a widespread taxon in Europe, exhibiting great intraspecific diversity phenotype and life history traits across its geographical distribution. Here, we studied body size, sexual dimorphism, age, growth rate condition of salamanders from the north-eastern margin range. In total, 2,102 individuals 23 populations representing Polish parts Sudetes Carpathian Mountains were sampled between 2004 2016. Body age showed significant differences...

Development of road system causes worldwide barriers to wildlife movement and leads mass mortality which is a serious threat the biodiversity, especially globally endangered amphibians. Animal carcasses, however, constitute an important non-invasive material for further research including species life history traits, but there little known whether road-killed animals are representative sample entire population.

Amphibian populations occurring at the margin of species range exhibit lower genetic variation due to strong drift and long-term isolation. Limited mobility site fidelity together with habitat changes may accelerate processes leading local extinction. Here, we analyze fire salamander subspecies Salamandra s. salamandra inhabiting Outer Carpathian region in Poland, northern border its distribution. Nuclear DNA polymorphism based on 10 microsatellite loci 380 individuals sampled 11 were...

ABSTRACT At their range limits, animal populations are often small and endangered. Moreover, they may use habitats in different ways than core populations, making the determination of habitat requirements an important aspect for effective long‐term conservation these populations.

Populations at the edge of their main range distribution are often exposed to suboptimal environments. They therefore exhibit a greater susceptibility towards habitat changes and clearly differ in structure dynamics from populations range.

Spotted form dominated east (69.2%, Carpathians) its frequency decreased to west (46.4%, Sudetes), where forms became more common.
