Niche Differentiation and Spatial Segregation of Melanistic and Non‐Melanistic Colour Morphs in a Widespread Palearctic Reptile Open
Aim This study investigates the spatial distribution and climatic niche differentiation between melanistic and non‐melanistic colour morphs of the common adder ( Vipera berus ) across the species range. We aim to elucidate the role of envi…

Melanism in Polymorphic Terrestrial Snakes: A Meta‐Analysis and Systematic Review Open
Background and Aim Colour polymorphic populations constitute excellent model systems for testing ecological and evolutionary hypotheses, as alternate colourations are associated with differences in various biological, behavioural and life‐…

<i>Natrix natrix</i> after dark: citizen science sheds light on the common grass snake’s nightlife Open
Activity patterns in animals are often species-specific, and can be generally categorized as diurnal, crepuscular, or nocturnal. Understanding these patterns provides insight into ecological adaptations and behaviors. The common grass snak…

Factor in Fear: Interference Competition in Polymorphic Spadefoot Toad Tadpoles and Its Potential Role in Disruptive Selection Open
Disruptive selection arises when extreme phenotypes have a fitness advantage compared to more-intermediate phenotypes. Theory and evidence suggest that intraspecific resource competition is a key driver of disruptive selection. However, wh…

Well-known species, unexpected results: high genetic diversity in declining Vipera ursinii in central, eastern and southeastern Europe Open
The Meadow and Steppe viper, Vipera ursinii-renardi complex is a well-studied group that is divided into several morphological subspecies. In this study, we combine the analyses of two mitochondrial genes with 9 microsatellite markers to c…

Ecological corridors for the amphibians and reptiles in the Natura 2000 sites of Romania Open
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 corr…

Evaluating taxonomic inflation: towards evidence-based species delimitation in Eurasian vipers (Serpentes: Viperinae) Open
The designation of taxonomic units has important implications for the understanding and conservation of biodiversity. Eurasian vipers are a monophyletic group of viperid snakes (Serpentes, Viperinae), currently comprising four genera ( Dab…

Anthropogenic impact or anthropogenic accommodation? Distribution range expansion of the common wall lizard (Podarcis muralis) by means of artificial habitats in the north-eastern limits of its distribution range Open
During 2005-2008, field observations were made on the distribution and habitat occupation by Podarcis muralis in the middle Bistrita river basin. Prior to our study, this lizard was known from only 5 localities in Romanian Moldavia (Bicaz,…
