Tadpoles of Microhyla ornata dwell in surface or column zones of water. They face predation threat from aquatic insect predators and carnivorous tadpoles of other anurans though they are invisible due to their transparent body form. We tested whether transparent body form of M. ornata tadpoles is a useful attribute against predation by exposing tail fin stained (with the Nile blue) subjects to a naturally occurring predator (Hoplobatrachus tigerinus tadpoles that detect prey using both visual and chemical cues). The study shows that susceptibility of stained M. ornata tadpoles to predation increased significantly compared to the unstained transparent individuals. We conclude that the transparent body form is of great significance in escaping predation during the larval phase of life in M. ornata.","PeriodicalId":50896,"journal":{"name":"Acta Herpetologica","volume":"15 1","pages":"55-57"},"PeriodicalIF":0.8,"publicationDate":"2020-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.13128/A_H-8871","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49500451","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}

Despite the conservation importance of educating the public about the docile nature of these species, few studies have attempted to quantify the response of viperid species to human interactions. Here we report the responses of free-ranging copperheads to a potential human encounter using a set of hierarchical behavioral trials. Out of a total of 69 snakes, only two individuals feigned striking and only two attempted to bite (3% of all individuals). Our results support the findings of previous studies documenting the docile nature of other viperid species and can hopefully be used to change the public perception of venomous snakes. Convincing the public and policy makers that viperid species are docile is critical to long-term conservation of these species in the U.S. and around the globe.","PeriodicalId":50896,"journal":{"name":"Acta Herpetologica","volume":"15 1","pages":"31-37"},"PeriodicalIF":0.8,"publicationDate":"2020-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.13128/A_H-7757","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48697555","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}

Numerous groups of animals were identified as potential vectors for the fungus, with crayfish and reptiles standing as the most prominent and consistent non-amphibian hosts warranting their inclusion in any future broadscale distribution surveys. an important area for future research. Additionally, Daphnia were noted to serve as predators of the zoospores when exposed in mesocosm scenarios, reducing infection levels in corresponding tadpoles. Caecilians have also been observed to be carriers of Bd, though the level as to which the chytrid impacts these organisms needs to be further researched. In total, this review indicates that future research needs to begin including freshwater crustaceans, caecilians and reptiles in field studies for presence/absence, while a broader range of taxa need to be tested to see whether they serve as vectors or hosts in natural scenarios.","PeriodicalId":50896,"journal":{"name":"Acta Herpetologica","volume":"15 1","pages":"39-45"},"PeriodicalIF":0.8,"publicationDate":"2020-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.13128/A_H-8744","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46400274","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 species has its known western limit of the distribution in the Veneto region of Italy. It is not known whether the species is really rare in Veneto or whether the area has been insufficiently surveyed. In addition, it is not known whether the westward distribution of the species is limited by a physiographic or by a climatic barrier. During the period 2016-2018, 118 sites were surveyed in the Veneto and Trentino-Alto Adige regions. Four new occurrences of Iberolacerta horvathi were discovered in Veneto that: 1) largely fill the gap between the westernmost known site and the closest site to the east; 2) extend further west the known distribution by 9 km. In addition the species was confirmed in three already known sites. A species distribution model was developed with the software MaxEnt, using 100 occurrences from Italy, Austria and Slovenia. The best model shows that the distribution is explained by the asperity of their habitat, the sedimentary bedrock, the aspect, the average temperature of the coldest quarter, the rainfall seasonality and the average summer rainfall. The last variable appears as the most likely responsible for the rarefaction of the species at its western limit. In addition, the species distribution model suggest that the Horvath’s rock lizard might be present in some additional mountain groups where it has so far not been found yet.","PeriodicalId":50896,"journal":{"name":"Acta Herpetologica","volume":"15 1","pages":"3-14"},"PeriodicalIF":0.8,"publicationDate":"2020-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47437086","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}

Both species hybridize in a wide area throughout Europe where their distribution overlaps. Therefore, there is a risk of introgression regarding the Bombina variegata population in north-eastern France. In order to assess the status of the introduced population of Bombina bombina and its origin, we investigated its genetic characteristics and structure using both mitochondrial (cytochrome b) and nuclear DNA (microsatellites markers). The results demonstrated a lack of introgression in the Bombina variegata population. Though experiencing a bottleneck effect, the introduced Bombina bombina population displays a high genetic diversity. If a propensity for expansion is found within the introduced population of Bombina bombina, it could be considered as a potential invasive species in France, and thus threaten the native species.","PeriodicalId":50896,"journal":{"name":"Acta Herpetologica","volume":"15 1","pages":"47-54"},"PeriodicalIF":0.8,"publicationDate":"2020-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47653620","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}

In this study, plasticity in growth rates, survival, larval period, and size at metamorphosis were examined in Bufo gargarizans gargarizans larvae under different combinations of temperature and food level. Our results showed that larvae metamorphosed at an older age when reared at 17.3°C. A significant interaction between food level and temperature revealed that the food level has obviously affected length of larval period when tadpoles raised at 17.3 °C, but not at 27.3 or 31.3 °C. Also, we found clear evidence that growth rates are influenced by both temperature and food level. Interestingly, tadpoles reared at 17.3 °C had larger size at metamorphosis than those reared at other temperatures, suggesting that B. g. gargarizans larvae reared at cold temperatures have a longer developmental period but they are also larger as metamorphs than conspecifics reared at warmer temperatures. Therefore, the global climate change or local manipulations of the environment may promote growth and development of B. g. gargarizans larvae, but not large size at metamorphosis.","PeriodicalId":50896,"journal":{"name":"Acta Herpetologica","volume":"15 1","pages":"65-69"},"PeriodicalIF":0.8,"publicationDate":"2020-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.13128/A_H-8119","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43317109","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 results obtained by this statistical approach were effective in estimating population size together with annual recruitment and survival. The tree-frog male population size remained constant between years and site abundance was inversely related with altitude.

We present the details of the marking procedure and examine the benefits and drawbacks of the technique considering the fossorial environment. After marking many individuals in a long-term field study, we can ensure that the marks were easily applicable and were not lost over a period of at least four years. Moreover, PIT tags did not negatively affect the body condition of amphisbaenians.
