The present paper describes the identity and taxonomic status and explains the taxonomic history of the butterfly originally named Lycaena alcon rebeli Hirschke, 1905 and generally misidentified and/or confused with Maculinea rebeli xerophila Berger, 1946. It is shown that Lycaena alcon rebeli Hirschke, 1905, is a rare individual form confined to h...

Aim We investigate the importance of interacting species for current and potential future species distributions, the influence of their ecological characteristics on projected range shifts when considering or ignoring interacting species, and the consistency of observed relationships across different global change scenarios. Location Europe. Method...

This comment rejects the proposal of Case 3508, requesting the Commission to use its plenary power to rule the precedence of Maculinea van Eecke, 1915, over Phengaris Doherty, 1891, in order to stabilise zoological nomenclature. We suggest that such an act would not serve this purpose but would, indeed, be likely to produce the opposite effect. (1)...

Vulnerability of 100 European butterfly species to climate change was assessed using 13 different criteria and data on species distributions, climate, land cover and topography from 1,608 grid squares 30′×60′ in size, and species characteristics increasing the susceptibility to climate change. Four bioclimatic model-based criteria were developed fo...

In the „Climatic Risk Atlas of European Butterflies” by Settele et al. (2008) some errors occurred for which we apologize and herewith present the corrections.

Climate change is one of the most influential drivers of biodiversity. Species-specific differences in the reaction to climate change can become particularly important when interacting species are considered. Current studies have evidenced temporal mismatching of interacting species at single points in space, and recently two investigations showed...

The overarching aim of the atlas is to communicate the potential risks of climatic change to the future of European butterflies. The main objectives are to: (1) provide a visual aid to discussions on climate change risks and impacts on biodiversity and thus contribute to risk communication as a core element of risk assessment; (2) present crucial d...

Why do areas with high numbers of small-range species occur where they do? We found that, for butterfly and plant species in Europe, and for bird species in the Western Hemisphere, such areas coincide with regions that have rare climates, and are higher and colder areas than surrounding regions. Species with small range sizes also tend to occur in...

Depending on their faunal content islands can function as important ‘vehicles’ for conservation. In this study, we examine data on 440 butterfly species over 564 European islands in 10 island groups. To determine the status of the butterfly fauna, we have adopted two approaches, island-focused and species-focused, examined using principal component...

Sakai's (1981) hypothesis (made in relation to material from Afghanistan) that the Pseudochazara baldiva-complex includes three species: P. baldiva (Moore, 1865), P. lehana (Moore, 1878), and P. droshica (Tytler, 1926) is tested by visual and statistical comparison of androconia scales from type and other specimens. The hypothesis is modifi ed for...

These analyses suggest that Parahipparchia specimens with male genitalia structure that associate them with the taxon H. muelleri may be more widely distributed than just in the type locality in the Aroania Mountains, southern Greece. This taxon also appears to be present in north-western Greece, Corfu and possibly further north in areas of the Bal...
