Reptiles are negatively affected by RIFA through predation of eggs, hatchlings, and adults. We used short-term (12-h) field trials early in incubation to evaluate whether RIFA could successfully depredate intact eggs from six species of native terrestrial oviparous snakes: North American Racer (Coluber constrictor), Speckled Kingsnake (Lampropeltis holbrooki), Prairie Kingsnake (L. calligaster), Rough Greensnake (Opheodrys aestivus), Black Ratsnake (Pantherophis obsoletus) and Great Plains Ratsnake (P. emoryi). Then we used an artificial nest field experiment at the end of incubation to test whether RIFA predation differed between a species that has apparently declined in areas of its range where RIFA has invaded (L. holbrooki) and a species that has apparently not declined (C. constrictor). We measured pip–hatch and incubation time for each species in the laboratory to determine whether differences in time between pipping and hatching (pip–hatch time) could account for interspecific differences in RIFA predation on eggs. Overall, RIFA predation rates on snake eggs were high for all species (25–67% during early trials, 50–100% at end of incubation), although P. obsoletus was only depredated after hatching in the field. Coluber constrictor had significantly shorter pip–hatch times than other species, but probability of predation by RIFA did not differ for C. constrictor and L. holbrooki. Our study provides novel observations of RIFA predation and suggests that time spent in nest, eggshell characteristics, and nest microhabitat may be more important than pip–hatch time in mediating vulnerability of snake eggs to RIFA predation.","PeriodicalId":56312,"journal":{"name":"Herpetologica","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2022-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49402118","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}

High-latitude range limits in areas where no physical barrier prevents dispersal are of particular interest in light of species range contraction or expansion because they represent limits that may inhibit occupancy. MacArthur proposed that abiotic factors have a greater influence on species distribution approaching high-latitude range limits. We examined aspects of environmental structure that influence distribution of Common Five-lined Skinks (Plestiodon fasciatus) and are expressed in that species' population dynamics. Eight sites in the southern Shield region of Ontario, Canada were surveyed during the active season for P. fasciatus. We collected data on the canopy cover, slope angle, slope aspect, substrate, cover type, and temperature at sites where P. fasciatus was observed (microsites) and compared these data to the general site conditions (macrosite). We assessed population size using capture–mark–recapture methods and compared population age structure at eight sites to detect if there was a correlation between the characteristics of the macrosites, population size, and age structure. Abiotic factors were the primary limiting factors affecting distribution at high-latitude range limits of the species. Spatial ecology at the individual scale was influenced by sites with suitable thermal conditions. Our results confirm the importance of microsites with suitable thermal profiles as key habitat for ectothermic vertebrates at high latitudes. The influence of temperature as a limiting abiotic factor is expressed in population density of P. fasciatus. Conservation and restoration of high-latitude populations of ectothermic vertebrates should focus on ensuring thermal requirements of the species are met before other factors are addressed, as temperature is likely the single most significant limiting factor at high-latitude range limits.","PeriodicalId":56312,"journal":{"name":"Herpetologica","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42015640","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}

Oligodon arnensis sensu lato is widely distributed throughout Peninsular India, Sri Lanka, Pakistan, Nepal, Bhutan, and Bangladesh. We demonstrate that southern, eastern, and western populations in India represent three distinct species. Oligodon arnensis sensu stricto described from Arnee (now Arani), Tamil Nadu, southern India, is distributed in southern India up to 1500 m above sea level. Oligodon albiventer Günther 1864 and Simotes russellii var. ceylonensis Müller 1887 described from Sri Lanka closely match O. arnensis sensu stricto, and hence we treat them as junior synonyms. We resurrect Coluber russelius Daudin 1803 from the synonymy of O. arnensis, designate a lectotype, and restrict its type locality to Vizagapatam (now Visakhapatnam), Andhra Pradesh, eastern Peninsular India. Based on morphological differences we describe a new species from Kurduvadi, in the Deccan plateau of western India representing the western Indian population of O. arnensis sensu lato. We provide redescriptions for O. arnensis sensu stricto and O. russelius comb. nov. based on museum specimens, as both were named based on illustrations (iconotypes). Based on our update of the currently confirmed localities for O. arnensis, O. russelius comb. nov. and the new species, we discuss their biogeography and conservation status.","PeriodicalId":56312,"journal":{"name":"Herpetologica","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47430105","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}

Populations established near expanding edges of their distributions are predicted to have greater endurance, an indicator of dispersal capability, than longer established populations. To assess endurance, we collected Cane Toads from a northern (edge) and southern (core) population in Florida, placed them into a track, and prodded them to hop. The number of prods (taps), hops, and time spent hopping were recorded, along with the total distance each toad moved on the track. Edge population toads were less willing to move and did not travel as far in the track as those from the core population. To further evaluate endurance, we placed an additional set of toads inside a treadmill, where movement was required to maintain equilibrium. Toads moved on the treadmill until reaching exhaustion. We measured blood lactate levels from each toad upon exhaustion and during a 3-h recovery period. After the treadmill trials, there was no population effect on the distances traveled by toads. There was also no population effect on lactate levels of toads when reaching exhaustion or during recovery. Overall, Cane Toads from our sampled northern edge population showed no differences in endurance compared to those sampled from the southern population in this study. This finding may indicate that further dispersal is limited in the northernmost populations of the Cane Toad range in Florida. Furthermore, the reluctance of Cane Toads to move in the track trials may indicate that selective pressures differ for edge populations in Florida.","PeriodicalId":56312,"journal":{"name":"Herpetologica","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46380920","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}

Phrynocephalus is one of the most diverse genera within the Agamidae family, with confusing or controversial taxonomy. This resulted in several independent suggestions for subspecies designations within Phrynocephalus versicolor. As the most dominant and abundant reptilian species in the Mongolian Gobi Desert, Phrynocephalus versicolor is ecologically important within the food chain of the ecological system it inhabits. We used 77 samples from 9 populations of P. versicolor in central and southern Mongolia. We amplified and sequenced 522–base pair (bp) –long fragment of the ND2 gene and recorded moderate levels of sequence diversity (Hd = 0.74 ± 0.023, π = 0.035 defined by 97 polymorphic sites). We conducted phylogenetic analyses using of Bayesian inference, maximum likelihood, and median-joining (MJ) network analysis that resulted in four well-supported clades (A, B, C, D) among our Mongolian samples. All of these clades, except Clade A, were population specific. The genetic distance values (mean Fst = 0.768), and analysis of molecular variance (AMOVA) also showed greater genetic distances between these clades. We ran a time-calibrated phylogenetic analysis using a strict molecular clock model with a single fossil calibration. The estimated divergence times in this study were comparable with previous findings, for example, 1.8 million years ago (mya) (1.31–2.94) for the node (Bayesian posterior probability [BPP] > 1.0 and bootstrap > 98) from which Clade A and B originated. In conclusion, our findings showed that there are at least three genetically distinct subspecies, namely P. v. versicolor, P. v. kulagini, and P. v. hispidus, with one previously unknown clade/lineage.","PeriodicalId":56312,"journal":{"name":"Herpetologica","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41632935","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 this study ACOs were placed in coastal sage scrub and grassland habitats in southern California and surveyed weekly for small terrestrial vertebrates over a 4-yr period. We observed 1643 individuals of 34 taxa during 143 survey sessions totaling 16,312 ACO days. Overall species richness and abundances under ACOs were highest from February to April. Our results showed that the probability of encountering a reptile under an ACO was highest in February and March under large wooden ACOs containing moist soil, when temperatures under the ACO were relatively mild, and when minimum air temperatures were low. At the community level, encounter probabilities for small mammals were highest for large wooden ACOs and ACOs with low soil moisture, with several species differences. Amphibians of three species were only captured in low numbers primarily under wooden ACOs from November to March. Use of ACOs in research and monitoring is an inexpensive and simple way to document and capture a wide variety of small terrestrial vertebrates. Species richness and abundance can be maximized over short periods using ACOs and can be equally important for long-term monitoring, particularly once the factors that make ACO use effective for small terrestrial vertebrates of a certain region have been investigated.","PeriodicalId":56312,"journal":{"name":"Herpetologica","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2021-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49182724","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}

Amphibian and reptile communities can be particularly sensitive to land-use change; therefore, understanding how land use and agricultural practices influence these communities in areas under increasing agricultural pressure is prudent. Over 10 yr, we sampled amphibian and reptile communities in and around 18 man-made ponds set within an agricultural/forest matrix on a military installation in western Tennessee. Ponds had either cattle access or were cattle restricted and had different surrounding land uses (forest, pasture, row crops, and industrial development). We used Akaike information criterion, corrected (AICc), model selection and nonmetric multidimensional scaling (NMDS) to assess how land-cover and pond characteristics influence amphibian and reptile richness, diversity, and community structure. Our results indicate that, despite reduced water quality, amphibian diversity was higher in ponds with cattle access, though this is likely influenced by surrounding forest, pasture, and row-crop cover. Pond permanence was important in shaping amphibian community structure and is a key factor in determining amphibian richness. We did not find any link between land cover and cattle access on reptile richness or diversity, though reptile community structure was influenced by cattle access, pasture, and row-crop cover.","PeriodicalId":56312,"journal":{"name":"Herpetologica","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2021-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42542358","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}
