Multiple Quaternary glacial refugia in the Iberian Peninsula, commonly known as “refugia within refugia”, allowed diverging populations to come into contact and admix, potentially boosting substantial mito-nuclear discordances. In this study, we employ a comprehensive set of mitochondrial and nuclear markers to shed light onto the drivers of geogra...
Article
Alytes maurus is one of the lesser-known amphibians of northwestern Africa. This small toad appears in several fragmented subpopulations in the mountainous systems of northern Morocco and it is threatened by deforestation and the pollution of streams. In this study, we evaluate, for the first time, the environmental factors (habitat and climate) th...
Article
Multiple threats, including emerging infectious diseases, are contributing to the extinction of amphibians worldwide. One of the most devastating diseases is the fatal amphibian skin disease chytridiomycosis caused by the fungus Batrachochytrium dendrobatidis (Bd). The presence of Bd in North Africa was described in 2011 and this included the distr...

Article
Full-text available
The salamander genus Salamandra is widespread across Europe, North Africa, and the Near East and is renowned for its conspicuous and polymorphic colouration and diversity of reproductive modes. The phylogenetic relationships within the genus, and especially among the highly polymorphic species S. salamandra, have been very challenging to elucidate,...
Article
Full-text available
One common approach to assigning conservation priorities during the current biodiversity crisis is to identify and direct efforts to high profile, vulnerable taxa, and important biodiversity areas. We addressed the first issue by assessing the comparison between conservation status and habitat suitability under differing climate change scenarios fo...
Article
Full-text available
North Africa is a climatically and topographically complex region with unique biotic assemblages resulting from the combination of multiple biogeographic realms. Here, we assess the role of climate in promoting intra-specific diversification in a Palearctic relict, the North African fire salamander, Salamandra algira, using a combination of phyloge...

For the first time, somatic chromosomes of Bufo spinosus were described (2n = 22). It was close to the karyotypes of other West-Palearctic species of the genus Bufo and consisted of 10 large metacentric (V), 2 large submeta-centric chromosomes (SV), 8 small metacentric (v), and 2 small submetacentric chromosomes (sv): 10 V + 2 SV + 8 v + 2 sv, NF =...

Full-text available
In this study, we report, through molecular identification, the first African records of a digenean trematode parasite of the genus Euryhelmis. We recovered metacercariae encysted in an anuran, the endemic Moroccan painted frog (Discoglossus scovazzi), and a vulnerable caudate, the North African fire salamander (Salamandra algira), from four locali...

The presence of Gasteracantha cancriformis (Linnaeus,1758) (Araneae: Araneidae), recently reported for the first time from Chile, is again confirmed. Thus the population of this species can be regarded as stable in Chile and the previous record does not represent a single isolated observation.
Article
Full-text available
The North African fire salamander, Salamandra algira, is distributed in Algeria, Morocco and Ceuta (Spanish territory located on the north coast of Africa), but until now rather limited information has been available on the populations across the Algerian part of its range. We here provide a first analysis of the phylogeography of this species in A...

Full-text available
We assessed the genetic variation of 47 Moroccan populations of the North African water frog ( Pelophylax saharicus) using partial sequences of the mitochondrial cytochrome oxidase subunit I gene (COI). All 239 samples belonged to the main haplotype clade previously identified from Morocco, with no haplotypes of the Algerian/Tunisian clades among o...

Painted frogs (Discoglossus) contain five to six species of Western Palearctic anurans that are mainly distributed in allopatry. We here provide the first comprehensive assessment of the phylogeography of the Moroccan species D. scovazzi and geographically characterize its contact zone with D. pictus in Eastern Morocco. Discoglossus scovazzi shows,...

Full-text available
Salamandra algira is patchily distributed from north-western Morocco to eastern Algeria. Its occurrence in Tunisia is under debate. In order to examine the presence of S. algira in Tunisia, three field trips were made to suitable habitats in the Medjerda mountains in north-eastern Tunisia. Additionally, phenotypic and morphological examinations of...

The amphibian fauna of the Kingdom of Morocco was traditionally regarded as poor and closely related to its European counterpart. However, an increase in research during the last decades revealed a considerable degree of endemism amongst Moroccan amphibians, as well as phenotypic and genotypic inter- and intraspecific divergence. Despite this incre...

Full-text available
The opening of the Gibraltar land bridge occurred at the end of the Messinian Salinity Crisis approximately 5.3 Mya, and was one of the main causes of vicariance between European and north-west African amphibians, resulting in the origin of several new species. However, little is currently known about the causes for post-Messinian amphibian differe...
Article
We report the occurrence of facultative paedomorphosis in the three species of newts (Pleurodeles waltl, Lissotriton boscai and Triturus pygmaeus) from dry and seasonal Mediterranean areas from southern Spain. These are the first records of paedomorphosis for P. waltl and L. boscai, and the second for T. pygmaeus. Other than the previous T. pygmaeu...

Full-text available
In northwest Africa some species from Sahelian origin appear with relict populations and apparently isolated by the extreme aridity of the Sahara desert. However very tolerant to aridity species could maintain continuous populations as might be the case for Echis leucogaster as indicated by results from genetic analysis and bioclimatic models. Resu...
Article
The European Smooth snake, Coronella austriaca Laurenti, 1768, presents a continuous distribution range across central and northern Europe, with isolated fragmented populations in the southern European peninsulas. Up to 814 bp of mitochondrial DNA from 34 specimens were used to determine the phylogeny and biogeography of this species within the Ibe...

Aim The intricate puzzle-like geography of the western Mediterranean is a product of long-term tectonic and orogenic events, supplemented by repeated climatic oscillations since the Pliocene. It offers numerous vicariance events that may be invoked to explain speciation in amphibians. We test for plausibility of two mutually exclusive Iberian–Afric...
