In this study, we aimed to understand the breeding ecology of five sympatric amphibians in the Republic of Korea – four anurans (Bufo sachalinensis, Rana uenoi, Rana coreana, Rana huanrenensis) and one caudata (Hynobius sp.) – by characterising their spawning habitat and to determine whether spawning site preference was influenced by species co-occurrence. We surveyed 120 water bodies focusing on the egg clutches to define the environmental properties associated with each taxa (water quality, depth, vegetation cover, topography and landscape), and we measured the distance between egg clutches and the bank of the water bodies (microhabitat). Habitats were partitioned among anurans along a gradient based on water depth. While the habitat used for spawning did not depend on species communities, the oviposition sites of R. uenoi and R. coreana varied in respect to their co-occurrence and the presence of the putative predator Hynobius sp. This suggests a plastic response in anurans’ reproductive behaviour potentially triggered by competitive interactions, and therefore subtle differences in microhabitats are significant yet overlooked drivers of breeding site selection.","PeriodicalId":50799,"journal":{"name":"Amphibia-Reptilia","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2022-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46552234","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}

Several studies have outlined the early history of Indian herpetology; however, few have traced the growth of this field since India’s independence. We analyse trends in Indian herpetology focusing on taxa, subfields, and authorship over the last 70 years. Of the 1177 published articles we analysed, 64.9% studied reptiles, 26.5% studied amphibians and 8.6% were general herpetofaunal studies. Frogs, lizards, and snakes being the most diverse herpetofauna groups, each accounted for 20-21% of the published articles and significantly outnumber publications on caecilians (2.3%), salamanders (0.4%), chelonians (12.6%), and crocodiles (4.4%). We found a significantly greater number of publications on Diversity & Distribution (34.2%), Taxonomy & Systematics (21.6%) and Ecology (19.4%) compared to other subfields, and detected a decline in Development, Physiology & Cytology and Evolutionary biology studies over the last four decades (1980-2019). The gender ratio among co-authors was dominated by men with only 29.7% of publications containing women authors. The overall proportion of women authors has not changed significantly over decades, but our analyses detected a significant decrease in women first authors and the proportion of women authors when the corresponding authors were men. Women authors were substantially lower in the subfield of Taxonomy & Systematics, and women published significantly more on amphibians compared to reptiles. Overall, we highlight the growth of herpetology in India from two key viewpoints, scientific pursuits, and gender parity among herpetologists.","PeriodicalId":50799,"journal":{"name":"Amphibia-Reptilia","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2022-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49084356","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}

Multiple snake lineages have independently evolved semiarboreal or completely arboreal species. As snakes lack limbs, the challenges of moving and feeding in an arboreal environment are numerous. Here we compare the prey-handling ability of the semiarboreal boa constrictor to the terrestrial ball python in a simulated arboreal context. Snakes were allowed to strike at rodent prey and attempt to swallow that prey while suspended. Boa constrictors were successful in feeding, using a complex suite of behaviors to maintain their position and manipulate their prey. Boa constrictors positioned rats so that swallowing occurred in the direction of gravity, and would use loops of their body to support the rat during swallowing. Ball pythons were frequently not successful in feeding, lacking the complex behaviors that boa constrictors frequently employed. Ball pythons would attempt to swallow, but in the majority of feeding attempts were ultimately unsuccessful. These unsuccessful feeding attempts were typically characterized by the ball pythons hanging upside-down, trying to swallow the prey against the direction of gravity. We suggest that behavioral modifications to feeding encouraged successful invasion of arboreal habitats, but more sampling of snake diversity is needed to explore the range and types of feeding behaviors that arboreal snakes employ.","PeriodicalId":50799,"journal":{"name":"Amphibia-Reptilia","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2022-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49336510","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, we applied spatially explicit capture-recapture (SECR) modelling customized for linear habitats to a three-year Capture-Mark-Recapture (CMR) monitoring of three populations of stream-dwelling Pyrenean brook newt (Calotriton asper), an endemic species of the Pyrenean mountain range. Our aim was to explore (1) spatial and temporal variation in population densities, home range size and individual detection probability during breeding season between populations and years, and (2) the influence of water temperature and flow on activity of newts. Estimates of population density range from 3044 to 4641 individuals/km of stream across the three years of the study. Linear home range along the stream was estimated to be 13.31 m from the home range centre on average over the three years. All detection probability estimates were similar, both between years and between sites, with a mean probability of 0.09, except in Fougax in 2020 where detection probability was 0.03. Activity of the Pyrenean brook newt was influenced by water temperature and flow, but these factors acted at different time scales. Overall, population densities are locally high in both populations but home range of the Pyrenean brook newt during breeding season is very small indicating a strong site attachment. The importance of water temperature and flow on activity emphasizes the sensitivity of the species to these factors that are forecasted to change in coming decades.","PeriodicalId":50799,"journal":{"name":"Amphibia-Reptilia","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2022-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44401384","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 aim of this study is to identify and quantify the species-specific set of environmental variables that stimulate males to produce mating calls under natural conditions. Call surveys were conducted at an active breeding pond on the edge of Parque Nacional Soberanía, Panama, during the breeding seasons of 2009 and 2010. Observations were made on 20 anuran species at the study site and we examined the onset of calling in nine species that were active and most consistently present during breeding seasons. We used logistic and linear regression models to investigate environmental conditions that affect calling for each species. The initiation of chorusing differed by species and key factors included ambient light, rainfall, and lunar cycle. Our data define the margins of a behavioural-environmental envelope that is species-specific and is not related to calling behaviour itself but is rather defined by physiological constraints related to environmental exposure.","PeriodicalId":50799,"journal":{"name":"Amphibia-Reptilia","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2022-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49468232","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}

Because of its restricted distribution, the species is potentially threatened by extinction due to anthropogenic impacts. Recently, the species has been listed in the IUCN Red List of Threatened Species as “Vulnerable” and included in CITES Appendix II and the Vietnam Governmental Decree – Group IIB. However, conservation activities to safeguard wild populations of G. lichtenfelderi have not yet been implemented due to a lack of detailed information about the population status and its ecological requirements. In this study, the micro-habitat use of G. lichtenfelderi was assessed. As a result of our field surveys, we found this species in evergreen forest areas with a high percentage of vegetation coverage and in close proximity to medium or small stream sections with rocky shelters on granitic formations. Canopy coverage, three micro-climatic variables (air, substrate temperature and humidity), weather condition and substrate type were the most important characteristics explaining the variation in the micro-habitat use of G. lichtenfelderi. Coupled with a macro-ecological (climate niche) approach, the complex niches of G. lichtenfelderi were defined by comparing them between two geographically distant populations in island and mainland sites. We found high similarities in macro-climatic and micro-habitat niches between the island and mainland populations of G. lichtenfelderi. Based on the ecological information, we recommend conservation actions to protect the core refugia of G. lichtenfelderi and reduce negative influences of anthropogenic impacts on wild populations in the future.","PeriodicalId":50799,"journal":{"name":"Amphibia-Reptilia","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2022-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48404567","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}
