The shape of turtle shells is impacted by locomotor efficiency, and shell shape has been shown to differ between populations occupying different water flow regimes. However, it is not known whether other aspects of the environment, such as water turbidity or plant density, similarly impact shape by influencing locomotor efficiency. We used geometric morphometric methods to analyze the shell shapes of Painted Turtles (Chrysemys picta) from several populations in Wisconsin. Water turbidity was found to be correlated with different shell shapes among the populations. In more turbid water, turtle shells were narrower than shells in clear water, and there was an interactive effect between water turbidity and plant density such that shells were anteriorly taller in high plant densities with high water turbidity than in low water turbidity. Shell shape also differed between the sexes and varied with adult size. These correlations suggest that aspects of the aquatic environment in addition to water flow may impact turtle shell shape by influencing locomotor efficiency and that this variation is detectable even within a species and region.","PeriodicalId":56312,"journal":{"name":"Herpetologica","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135031741","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, very little is known about the life history, ecology, and distribution of this frog, representing the monotypic genus Chrysopaa (Dicroglossidae). Similarly, data about the larva of this taxon are scarce. Thus, we provide the first detailed imagery and description of the larval stage of C. sternosignata (Dubois and Khan 1979) from Afghanistan. One tadpole was obtained from Jabul Saraj, Charikar, Afghanistan. Morphological and genetic analysis of mitochondrial and nuclear DNA confirmed the identity of the larva as C. sternosignata. Tadpole characters were illustrated by photos. Basic measurements and details on oral apparatus provide relevant characteristics to delimit the larva of this species from other spiny frogs.

For this purpose, noninvasive and invasive methods to identify consumed prey have been used. Here, we investigated the diet of male and female European Green Lizards (Lacerta viridis) by sampling fecal pellets across 2 yr in the spring and late summer at a single site. We used the following two methods for identifying prey remnants from fecal samples: the classical macroscopic approach that requires competent expert knowledge and the molecular approach based on the dietary metabarcoding of nondegraded prey remnant DNA. According to both methods, lizards consumed mainly insects belonging to 13 orders, with Coleoptera as the dominant prey. The number of prey taxa was similar between the sexes, but the prey composition at the genus level was significantly different, with males capturing some coleopterans more than females. The diets also differed significantly between season. In the spring, lizards consumed many more prey types and many more coleopteran specimens than in late summer. The proportion of identified prey taxa was significantly different between the identification methods. From the total of identified prey, macroscopic identification yielded only about 50% of taxa, whereas molecular identification yielded more than 80% of taxa. Our results show that molecular identification can recover a much higher number of prey than the macroscopic method, yet not all prey. Thus, the integration of both methods best described the natural diet and complex trophic interactions of European Green Lizards.","PeriodicalId":56312,"journal":{"name":"Herpetologica","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135031934","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The species are representative of the three life-history modes associated with habitat utilization in Desmognathus, namely stream, streamside, and forest. The two assemblages include the largest and smallest members of the genus. Among species, I recorded a negative correlation between body size and relative offspring size, a positive correlation between body size and lifetime offspring number, but negative correlations between body size and both lifetime reproductive investment and productivity, as reflected in the decrease in body size with increasing relative offspring size. In comparing these trends with published data on variation in these parameters in animals generally, I conclude that desmognathan salamanders lie at the slow end of the fast–slow axis in the pace-of-life model of life-history evolution. I discuss possible population regulatory mechanisms that operate on these populations, as a function of life-history mode, with special emphasis on streamside species. I suggest that retention of a brief larval phase in streamside species reflects tradeoffs among dispersal-related traits, including survival and growth.","PeriodicalId":56312,"journal":{"name":"Herpetologica","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135031750","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For many species, we lack the necessary data to implement habitat management or conservation plans because the species may be rare or difficult to detect, particularly at the periphery of geographic ranges. This may be especially true for snakes. For example, Pygmy Rattlesnakes (Sistrurus miliarius) have state-level protection at the northern terminus of the range but what little is known about the species in this region is derived from just 30 observations collected over the past 40 yr. This leaves considerable uncertainty regarding conservation status and establishes a need to better understand habitat suitability and their geographic distribution. Therefore, the objectives of our study were to determine landscape-scale environmental variables that influence patterns of distribution for S. miliarius in the northern extent of its range via the Maxent Species Distribution Algorithm coupled with on-site monitoring via standardized road-cruising transects (n = 43) to evaluate model suitability. The resulting species distribution model showed that suitable habitat (∼2045.96 km2) was composed primarily of riparian areas that exist in isolated patches. These habitats were primarily composed of sandy soils and low-elevation forested areas. Our on-site monitoring, informed by our modeling efforts, resulted in 12 new records for the species (an increase of 28.57%). Collectively, our species distribution model suggests that suitable habitat for S. miliarius within our study area is restricted to riverine or riparian habitats associated with the Lower Tennessee River Valley. The methods used in this study employ a strategy to better understand suitable habitat for rare or secretive species that occur across large geographic areas.","PeriodicalId":56312,"journal":{"name":"Herpetologica","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2023-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139368023","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To quantify nestedness, we used the metric NODF (nested overlap decreasing fill). We also explored interannual variability in nestedness and in temporal patterns of alpha, beta, and gamma diversity. The maximally packed matrix for ponds showed a nested pattern at middle and high elevation, whereas for streams, the nested pattern occurred at low elevation. In both types of wetlands, the magnitude of nestedness was moderate, around 15–30%. On the other hand, nestedness was not found to increase or decrease over the study period, for both ponds and streams, or at the three levels of elevation. This temporary stability was also found for alpha, beta, and gamma diversities. The moderate nestedness pattern detected was most likely explained by selective removal of species, a poor connection among water points, historical destruction of wetlands, or major land-use changes associated with the abandonment of traditional farming activities. Our results denote a certain resilience to human disturbance by the studied amphibian species. However, these results stress the need of protecting the metacommunity as a whole (because of the relative importance of species turnover among sites), and emphasize the suitability of preserving the old mosaic landscape at least within protected areas. Our results are intermediate between those expected for the temperate zone and those expected for lower latitudes, likely because the study region is a biogeographical transition area.","PeriodicalId":56312,"journal":{"name":"Herpetologica","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2023-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46841912","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
