Mass mortality episodes recorded in Europe indicate that investigations of unstudied species should focus on members of the frog family Alytidae. Here, we report the combined results of a field survey and laboratory observations of field collected Alytes dickhilleni. Our data support the hypothesis that B. dendrobatidis has recently emerged in at least two disjunct locations in the species range and populations across much of the species range lack evidence of infection pathogen. Tadpoles taken into the laboratory from sites with infection experienced 70% mortality, unlike those taken into the laboratory from uninfected sites, and both infection and strength of infection was associated with mortality in animals collected from infected locations. Several conservation interventions are underway in response to our study, including the establishment of a captive assurance colony, a public awareness campaign, and experimental tests of disease mitigation schemes.

  • Review Species List of the European Herpetofauna – 2020 Update by the Taxonomic Committee of the Societas Europaea Herpetologi
    Amphibia-Reptilia 41 (2020): 139-189 brill.com/amre Review Species list of the European herpetofauna – 2020 update by the Taxonomic Committee of the Societas Europaea Herpetologica Jeroen Speybroeck1,∗, Wouter Beukema2, Christophe Dufresnes3, Uwe Fritz4, Daniel Jablonski5, Petros Lymberakis6, Iñigo Martínez-Solano7, Edoardo Razzetti8, Melita Vamberger4, Miguel Vences9, Judit Vörös10, Pierre-André Crochet11 Abstract. The last species list of the European herpetofauna was published by Speybroeck, Beukema and Crochet (2010). In the meantime, ongoing research led to numerous taxonomic changes, including the discovery of new species-level lineages as well as reclassifications at genus level, requiring significant changes to this list. As of 2019, a new Taxonomic Committee was established as an official entity within the European Herpetological Society, Societas Europaea Herpetologica (SEH). Twelve members from nine European countries reviewed, discussed and voted on recent taxonomic research on a case-by-case basis. Accepted changes led to critical compilation of a new species list, which is hereby presented and discussed. According to our list, 301 species (95 amphibians, 15 chelonians, including six species of sea turtles, and 191 squamates) occur within our expanded geographical definition of Europe. The list includes 14 non-native species (three amphibians, one chelonian, and ten squamates). Keywords: Amphibia, amphibians, Europe, reptiles, Reptilia, taxonomy, updated species list.

  • And Intraspecific Levels Reveal Hierarchical Niche
    www.nature.com/scientificreports OPEN Niche models at inter‑ and intraspecifc levels reveal hierarchical niche diferentiation in midwife toads Eduardo José Rodríguez‑Rodríguez 1*, Juan F. Beltrán 1, Miguel Tejedo 2, Alfredo G. Nicieza 3,4, Diego Llusia 5,6, Rafael Márquez 7 & Pedro Aragón 8 Variation and population structure play key roles in the speciation process, but adaptive intraspecifc genetic variation is commonly ignored when forecasting species niches. Amphibians serve as excellent models for testing how climate and local adaptations shape species distributions due to physiological and dispersal constraints and long generational times. In this study, we analysed the climatic factors driving the evolution of the genus Alytes at inter- and intraspecifc levels that may limit realized niches. We tested for both diferences among the fve recognized species and among intraspecifc clades for three of the species (Alytes obstetricans, A. cisternasii, and A. dickhilleni). We employed ecological niche models with an ordination approach to perform niche overlap analyses and test hypotheses of niche conservatism or divergence. Our results showed strong diferences in the environmental variables afecting species climatic requirements. At the interspecifc level, tests of equivalence and similarity revealed that sister species were non-identical in their environmental niches, although they neither were entirely dissimilar. This pattern was also consistent at the intraspecifc level, with the exception of A. cisternasii, whose clades appeared to have experienced a lower degree of niche divergence than clades of the other species. In conclusion, our results support that Alytes toads, examined at both the intra- and interspecifc levels, tend to occupy similar, if not identical, climatic environments.

R. Allain1 & Amanda L. J. Duffus2 1 Durrell Institute of Conservation and Ecology, University of Kent, Canterbury, Kent, UK 2 Department of Natural Sciences, School of Nursing, Health, and Natural Sciences, Gordon State College, Barnesville, Georgia, USA In the past decade, infectious disease threats to European herpetofauna have become better understood. Since the 1990s, three major emerging infections in amphibians have been identified (Batrachochytrium dendrobatidis, B. salamandrivorans, and ranaviruses) as well as at least one of unknown status (herpesviruses), while two major emerging infections of reptiles (Ophidiomyces ophiodiicola and ranaviruses) have been identified in wild European populations. The effects of emerging infections on populations have ranged from non-existent to local extirpation. In this article, we review these major infectious disease threats to European herpetofauna, including descriptions of key mortality and/or morbidity events in Europe of their emergence, and address both the distribution and the host diversity of the agent. Additionally, we direct the reader to newly developed resources that facilitate the study of infectious agents in herpetofauna and again stress the importance of an interdisciplinary approach to examining these infectious diseases.
