The relictual population is currently listed with protections under the U.S. Endangered Species Act but the status of the population in the remainder of the species' range has not been assessed, and there is concern that it may be at risk of extinction without protection. The U.S. Fish and Wildlife Service requires scientific information of the species' status to inform conservation decisions. There is little empirical information available from P. rubriventris populations and, furthermore, the majority of what exists comes from the disjunct northern subpopulation. To fill data gaps in the species' life history and reduce geographic bias, we supplement available data from P. rubriventris with demographic rate estimates from other Pseudemys species to parameterize an age-structured population projection model. Our estimate of mean population growth rate was 0.987 (0.92–1.04), indicating that P. rubriventris populations may be in decline. However, there was considerable uncertainty in our results, with 35% of projections resulting in stable or increasing populations. Additional uncertainty about parameter values, geographic variation, and current threats limit the assessment. We discuss the merits and limitations of our population projection modeling (PPM) approach where other analytical methods are precluded by lack of available data.","PeriodicalId":54821,"journal":{"name":"Journal of Herpetology","volume":"56 1","pages":"362 - 369"},"PeriodicalIF":0.8,"publicationDate":"2022-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46646638","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}

For taxa that are difficult to visually distinguish at the species level, this problem can be compounded by misidentification of existing records. Citizen science has emerged as a potentially powerful tool to increase species observation data, but whether it can meaningfully add to our understanding of the distributions of species that are typically difficult to identify is contentious. We evaluated the volume, spread, and species identification accuracy of 3 yr of data from an acoustics-based citizen science dataset with a national aggregate of species observations collected over more than 140 yr (i.e., unvouchered human observations, photo-vouchered citizen science observations, and preserved specimens) to demonstrate the boundaries of five small, morphologically conserved frog species in eastern Australia. The national aggregate contained the most species records; however, the annual rate of record collection was much greater in the acoustic citizen science dataset. A high proportion of likely misidentified records were detected in the national aggregate dataset. Spatial bias differed between datasets, with acoustic citizen science data more biased toward highly populated areas. We demonstrate that citizen science can collect large volumes of spatially and taxonomically valid data which, especially when used in combination with more traditionally collected species records, can inform the detailed delineation of ranges in historically confusing groups of frog species.","PeriodicalId":54821,"journal":{"name":"Journal of Herpetology","volume":"56 1","pages":"318 - 323"},"PeriodicalIF":0.8,"publicationDate":"2022-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44819206","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}

Sexual dichromatism, where males and females of the same species differ in coloration, is best studied in diurnal animals. Nocturnal animals such as frogs do not seem good candidates for widespread sexual dichromatism, or for the use of visual signals in social communication in general. Yet, up to 25% of treefrog species (Anura: Hylidae) show some degree of sexual difference in their dorsal coloration. The ventral side of frogs is hidden during rest, but the throat region becomes visible in active individuals, especially in calling males. We compiled a database of 249 treefrog species that include members of all seven subfamilies of the Family Hylidae. We document that the throat region of male frogs is frequently colorful and of a different color than the abdomen (ventral dichromatism), that there is interspecific variation in throat coloration, and that males and females differ in throat coloration (sexual dichromatism). We also examined intraspecific variation in throat coloration, using Eastern Gray Treefrogs, Dryophytes versicolor (Hyla versicolor) as the focal species. Here, we document throat color is sexually dimorphic, that it varies among males, is associated with better body condition, and on average is darker in mated compared to unmated males. Our study finds that throat color dichromatism is the most prevalent type of sexual dichromatism in treefrogs, and that throat coloration may have sexual signal function.","PeriodicalId":54821,"journal":{"name":"Journal of Herpetology","volume":"56 1","pages":"294 - 301"},"PeriodicalIF":0.8,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46820569","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}

Exposure to predators during early life stages can alter behavioral and physical traits during ontogeny. This is important for biphasic amphibian species because juvenile movement behavior can be shaped by carry-over effects of the larval environment and direct effects of abiotic conditions in terrestrial habitats. We explored the interaction of aquatic predator cue exposure, juvenile morphology, and abiotic terrestrial conditions on the movement behavior of postmetamorphic Northern Red-legged Frogs (Rana aurora). We quantified carry-over effects of aquatic predator cues and direct effects of substrate conditions on individual movement behavior using a combination of seminatural enclosed runways and powder tracking assays. We found a latent effect of aquatic condition, such that crayfish-exposed individuals had greater relative body condition at metamorphosis, and all predator-exposed individuals had larger body lengths relative to controls. Terrestrial conditions were the dominant factor shaping movement behavior. During runway movement assays, individual conditional movement displacement was likely greater in dry soil and low humidity conditions than in moist conditions with high humidity. For nocturnal powder tracking assays, individuals were more likely to have greater path distances during warmer temperatures, whereas paths were less meandering in cooler, dry conditions. Morphologically larger individuals moved greater distances only during the powder tracking assays. We observed latent effects of aquatic predator exposure on juvenile morphology; however, the relationship between these changes and the relative importance of direct environmental conditions in shaping movement behavior is unclear. Our results demonstrate the interconnected nature of aquatic and terrestrial environments in shaping the movement of juvenile amphibians.","PeriodicalId":54821,"journal":{"name":"Journal of Herpetology","volume":"56 1","pages":"302 - 311"},"PeriodicalIF":0.8,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47093991","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}

Ophidiomycosis (snake fungal disease; SFD) is a disease of conservation concern caused by the fungus Ophidiomyces ophidiicola that threatens the health of snake populations worldwide.

In our study, we compared the prevalence of ophidiomycosis between a low-impacted forest site (n = 93) and a highly disturbed remediated landfill (n = 53) in Anderson County, Tennessee, USA. Free-ranging snakes were examined for the presence of skin lesions that are consistent with ophidiomycosis and were swabbed to detect O. ophidiicola DNA using quantitative PCR (qPCR). Apparent ophidiomycosis (qPCR-positive and skin lesions present) was diagnosed at both sites, but there was no significant difference in prevalence between the two sites (24.7% at the forest site; 22.6% at the landfill site). Apparent ophidiomycosis was most prevalent in Racers (38%; Coluber constrictor) and Ring-Necked Snakes (26%; Diadophis punctatus). There was no difference in ophidiomycosis status between sites for the most-sampled species: Racers, Black Rat Snakes (Pantherophis obsoletus), and Ring-necked Snakes (Diadophis punctatus). Our study represents the first report of ophidiomycosis at focal sites in Tennessee.

From these comparisons we herein describe a new cryptic species. Boana guarinimirim sp. nov. differs from its closely related species by the presence of a supracloacal crest, calcar appendage, and conspicuous discs on toes. Nevertheless, the new species could not be completely discriminated from its distantly related taxon B. polytaenia. We applied the new name to the clade distributed throughout the northern Mantiqueira range (Boana sp. 3), but the new name could also be applied to the clade from southern Espinhaço range (Boana sp. 4).

Our aim was to analyze the dietary composition of an invasive population of Lithobates catesbeianus tadpoles and to evaluate the degree of dietary changes among activity months. We hypothesized that bullfrog tadpoles would exhibit temporal changes in diet, consistent with the variation of tadpole size and availability of resources. We collected 94 bullfrog tadpoles and identified 50 taxa in their digestive tracts. The items most frequently consumed were microalgae of the genera Navicula (frequency of occurrence [Fo] = 19) and Cymbella (Fo = 17). The trophic niche breadth was 8.13, which is considered moderate-high. The trophic habits of L. catesbeianus larvae changed seasonally, with the diets during October and December being numerically similar (Morisita's quantitative index = 0.86). The composition of the diet had a similarity of 63% (Jaccard's qualitative index) between August and October. The larvae of L. catesbeianus collected during the different months showed significant differences in their stages of development and body mass. On average, individuals were larger and more developed in the month of December, which was to be expected given that the abundance of prey items is greatest during the summer season.

Establishing the social system of a population is key to studying the evolution of behaviors. However, observations of social interactions needed to infer social systems are difficult to obtain for many species. An alternative way of understanding social systems is by studying the space-use pattern of individuals. Along with ecological factors, space use is largely governed by interactions among individuals: typically, competing individuals avoid each other, and individuals benefitting from each other share space. We investigated the social system, specifically the mating system, and the nature of intrasexual interactions between adults, by quantifying space-use patterns of individuals over their adult lifespan in the tropical Psammophilus dorsalis lizard. Males had substantially larger home ranges than females during the mating season, but not during the nonmating season. Female home ranges were small, and showed minimal overlap with other females throughout their lifespan, suggesting consistent intrasexual competition among females. In contrast, males showed minimal overlap with other males in the nonmating season but increased overlap in the mating season, suggesting that males resolve intrasexual competition through other means, like contests, during the mating season. Patterns of overlap between male and female home ranges in the mating season indicated a socially polygynous mating system. Our study provides an initial understanding of home-range patterns and associated inferences of within- and between-sex interactions across the lifespan of a tropical lizard, Psammophilus dorsalis. It highlights the insights into the social structure of a population gained from dispersion patterns of individuals.","PeriodicalId":54821,"journal":{"name":"Journal of Herpetology","volume":"56 1","pages":"164 - 171"},"PeriodicalIF":0.8,"publicationDate":"2022-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44727376","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}

Turtle populations around the world are continually confronted with changing environments that affect their ecology and conservation status. Among freshwater turtles, population dynamics are thought to be mediated by complex yet often cryptic causes. One recent direction of focus in addressing these causes is the turtle-associated microbiota. In turtles, the gut-associated microbiota is of exceptional interest due to its continual association with host species under changing conditions. Diet-based fluctuations and changes in microbial diversity may correspond to varying external environments at both the individual and population level. Environmental responses are of particular interest due to the anthropogenic changes that may underlie them. Pollutants, disruption of climatic patterns, and habitat fragmentation all have the potential to affect turtle-associated microbiota and subsequent population and species conservation. To better understand potential human-induced changes, the diversity of turtle-associated microbiota over local spatial gradients must be better understood. We examined microbial community α- and β-diversity among 30 adult False Map Turtles (Graptemys pseudogeographica) at three sites within the lower Missouri River, United States. Our results indicate significant microbial community centroid differences among sites (β-diversity), which are likely mediated by various local environmental factors. Such factors will have to be carefully considered in any future attribution of anthropogenic determinants on turtle-associated microbiota as it relates to turtle population dynamics.","PeriodicalId":54821,"journal":{"name":"Journal of Herpetology","volume":"56 1","pages":"258 - 265"},"PeriodicalIF":0.8,"publicationDate":"2022-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48738799","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}
