The chytrid fungal pathogen has been first described in North Africa in 2011. The present work reported the first survey on Bd prevalence and intensity in the Tensift region of Morocco. The survey has been conducted on 11 different localities by collecting skin swabs and tissue samples of 97 individuals. Using a quantitative Polymerase Chain Reaction (qPCR) protocol, low-intensity of Bd infection has been detected in the area of study. In fact, the chytrid fungal pathogen has been identified in 10 individuals distributed in six of the 11 sites investigated, placing the 95% confidence interval for overall prevalence at 5.5-19.6%. The survey confirmed the occurrence of Bd at both high and low altitude localities, on four species out of seven known to inhabit the region and added two additional species (Pelophylax saharicus and Sclerophrys mauritanica) to the list of Bd susceptible amphibians in Morocco. The present records extended Bd distribution more than 400 km in the South of Morocco, indicating that the chytrid fungal pathogen is more widespread in the country than previously thought.","PeriodicalId":50896,"journal":{"name":"Acta Herpetologica","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2019-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.13128/A_H-7748","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46306121","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

What kind of eco-ethological adaptations or evolutionary adjustments enables this gecko to persist? The present study explores the interaction between the endemic European Leaf-toed gecko (Euleptes europaea) and the alien Black rat (Rattus rattus). In the last 30 years, we compared 26 populations inhabiting “rat” and “rat-free” islands and islets in Tunisia, Sardinia, Corsica and Southern France. Geckos’ populations can persist despite the occurrence of rats. In the presence of rats: 1) geckos’ average body size tends to decrease towards medium-sized individuals; 2) geckos shift their spatial behaviour avoiding to forage “in the open”; 3) geckos’ body condition is not affected by the presence of rats. Moreover, shortly after rats’ eradication, geckos’ population structure seems to change and larger sized geckos prevail while the spatial behaviour is much more conservative. The mechanisms driving the interactions between the two species still need to be explained. Rats could represent a stressor for geckos, compete for space, be pest vectors and even predators. Coexistence of natives and aliens requires adaptive plasticity and evolutionary adjustments. In contexts where the risk of reinvasion is high, eradication programs need to be carefully evaluated, since the arrival of “new rats” on an island could have much more damaging effects on the insular biota than those caused by the eradicated population.","PeriodicalId":50896,"journal":{"name":"Acta Herpetologica","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2019-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.13128/A_H-7746","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42707449","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When compared to other species, P. siculus underwent fewer revisions and the number of species hidden within this taxon may have been, therefore, underestimated. However, recent studies based on genetic and morphological data highlighted a marked differentiation of the populations inhabiting the Western Pontine Archipelago. In the present work we used published genetic data (three mitochondrial and three nuclear gene fragments) from 25 Podarcis species to provide a multilocus phylogeny of the genus in order to understand the degree of differentiation of the Western Pontine populations. In addition, we analyzed new morphometric traits (scale counts) of 151 specimens from the main islands of the Pontine Archipelago. The phylogenetic analysis revealed five principal Podarcis groups with biogeographic consistency. The genetic distinctiveness of the Podarcis populations of the Western Pontine Islands is similar or even more ancient than those observed in numerous other pairs of Podarcis sister species. In the light of these evidences we raise the Western Pontine lizards to specific rank; thus they should be referred to as Podarcis latastei.","PeriodicalId":50896,"journal":{"name":"Acta Herpetologica","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2019-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.13128/A_H-7744","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42911692","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we assess the impact of substrate type on the sprint performance (maximum speed and acceleration) of Schreiber’s fringe-fingered lizard (Acanthodactylus schreiberi). This species is a skillful runner that also bears micro spike-like protruding scales on its toepads (toe fringes), an adaptation for locomotion on sand. We worked with three populations living in habitats that differ in substrate type (sand, soil and rock). We measured sprint performance using a race-track with custom substrate platforms replicating the different substrate types. We formulated two hypotheses: first, we anticipated that the three populations would differ in their sprint performance due to the differences in substrate type; second, we expected that each population would perform better on its home substrate. Our results generally refuted the hypothesis that sprint performance would differ on different substrate types. Our results suggest that there is a restricted effect of substrate type on locomotion and indicate a multifactor interplay among alternative underlying parameters.","PeriodicalId":50896,"journal":{"name":"Acta Herpetologica","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2019-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.13128/A_H-7745","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45706245","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The design included predator-naive or predator experienced prey subjects, and presence or absence of a natural shelter. Water scorpion adult individuals ( Laccotrephes species) provided predation threat and also an opportunity to the prey to experience a direct danger of predation. Both previous experience with predators and availability of shelters affected larval survival independently and not conjointly. A prior encounter with predators enabled prey tadpoles to escape predation more effectively with a significant increase in their survival in comparison to the predator-naive subjects. Similarly, access to refuge sites significantly increased survival of predator-naive as well as predator experienced tadpoles compared to that in the absence of shelters. Clearly, ability to sense water borne predacious cues in the vicinity and use refuge sites plays a key role in escaping from predation in the bronze frog tadpoles.","PeriodicalId":50896,"journal":{"name":"Acta Herpetologica","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2019-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.13128/ACTA_HERPETOL-22855","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47869972","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
