Recordings were made in spring of 2019 in controlled laboratory conditions using a commercially available omnidirectional hydrophone connected to a linear PCM recorder. A total of 27 animals (21 males, 6 females) were recorded under different conditions: (a) alone in an empty tank, (b) alone in a tank full of vegetation, and (c) a pair in an empty tank. Results indicated that both male and female newts produced a click-like sound with a mean duration of 34 ms (± 5.31 SD; range: 27-51) and mean peak frequency of 1887 Hz (± 405 SD; range: 1162-2770). Not all newts tested produced sounds and there were no statistically significant differences between males and females or recordings under different conditions in terms of click number, duration and frequency parameters, with the exception of the ratio of peak frequency/bandwidth at 50% peak amplitude, which was lower for clicks produced in the vegetated tank. Newt snout-vent length and body mass also had no effect on any of the studied parameters. The obtained results suggest that clicks could have a function in orientation and exploratory behaviour.","PeriodicalId":50896,"journal":{"name":"Acta Herpetologica","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2020-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.13128/A_H-7863","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48677269","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}

To this end, 23 different studies collected from the Web of Science database along with two external journals were utilized, encompassing numerous taxonomic groups. 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":null,"pages":null},"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":null,"pages":null},"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}

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":null,"pages":null},"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}
