We analyzed three nested data sets separately: (1) all turtles, (2) freshwater turtles, and (3) aquatic turtles. We georeferenced North American turtle distributions, then we created presence–absence matrices for each of the three data sets. We used watershed unit as biogeographic units. We conducted an unweighted pair-group method with arithmetic mean clustering analysis on each Jaccard index distance matrix from our watershed species matrices to delineate biogeographic provinces. Provinces were then tested for significant differences in species compositions in a global model with the use of a one-way analysis of similarity. We conducted a best subset of environmental variables with maximum (rank) correlation with community dissimilarities that determined the best model of abiotic variables explaining province delineation (i.e., climate, topography, and stream channel). To identify which species contributed the most to province delineations, we conducted an indicator species analysis and a similarity-percentage analysis. There were 16 all-turtle provinces, 15 freshwater provinces, and 13 aquatic provinces. Species compositions delineating the provinces were explained by abiotic variables, including mean annual precipitation, mean precipitation seasonality, and diversity of streams. Province delineations correspond closely with geographical boundaries, many of which have Pleistocene origins. For example, rivers with a history of carrying glacial runoff (e.g., Arkansas, Mississippi) sometimes dissect upland provinces, especially for aquatic and semiaquatic turtles. Compared with freshwater fishes, turtles show greater sensitivity to decreased temperature with restriction of most taxa south of the last permafrost maximum. Turtles also exhibit higher sensitivity to climatic, geomorphic, and tectonic instability, with richness and endemism concentrated along the more stable Gulf of México and Atlantic (south of the last permafrost maximum) coasts. Although distribution data indicate two aquatic turtles are most cold tolerant (i.e., Chrysemys picta, Chelydra serpentina), aquatic turtles overall show the most restriction to warmer, wetter climates. Sequential addition of semiaquatic and terrestrial turtles into analyses shows, as expected, that these taxa flesh out turtle faunas in climatically harsh (e.g., grasslands) or remote (e.g., California, Sonoran Desert) regions. The turtle assemblages of southwestern versus southeastern North America are distinct. But there is a transition zone across the semiarid plains of the Texas Gulf Coast, High Plains, and Chihuahuan Desert, including a strong boundary congruent with the Cochise Filter-Barrier. This is not a simple subdivision of Neotropical versus Nearctic taxa, as some lineages from both realms span the transition zone.","PeriodicalId":56309,"journal":{"name":"Herpetological Monographs","volume":null,"pages":null},"PeriodicalIF":2.5,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1655/HERPMONOGRAPHS-D-16-00013","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48987533","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we describe an intensive capture–mark–recapture study of L. getula conducted during 1974–1978 in a canal bank–Water Hyacinth (Eichhornia crassipes) community at Rainey Slough in southern Florida, where annual capture probabilities of adults ranged from 0.662–0.787. Population size and structure, seasonal activity, movements, microhabitat use, behavior, thermal ecology, and predator–prey relationships are described. At this site kingsnakes were susceptible to capture mostly in winter and spring, were diurnal, used rodent (Sigmodon hispidus) burrows on canal banks as nocturnal retreats, and emerged from burrows on 13–26% of the sampling days. Overlap of burrow use by both sexes was extensive with no evidence of territoriality. Kingsnakes readily entered the Water Hyacinths to bask, pursue mates, and forage. At Rainey Slough only snakes were detected in the diet of kingsnakes. Concurrent sampling of potential snake prey in the hyacinths and on canal banks revealed 10 species that varied in use of the two sampled habitats and in body size. A range-wide analysis confirmed that in descending order snakes, reptile eggs, and lizards dominate the diet of L. getula in Florida (94.8%) and remain important prey types elsewhere (80.2%). At Rainey Slough the density of six species of semiaquatic snakes in Water Hyacinths averaged 3534 individuals/ha with a mean annual biomass of 135.8 kg/ha, and kingsnake biomass was only 2.2–3.9% of prey snake biomass. We estimated that the kingsnake population consumed 36.82–63.58 kg/yr, or about 10.0–17.2% of the standing crop of snakes in the Water Hyacinth community. Adult male L. getula lost on average 39.3% of their body mass associated with the spring reproductive season, whereas females lost only 3.4% in the same period. Body condition indices for both sexes improved substantially thereafter. In follow-up surveys at Rainey Slough during 2006–2010 no kingsnakes were found. Semiaquatic snake densities in the Water Hyacinths were 77.2% lower (807.4/ha) than in the 1970s and consisted of only three species. Compared to the enigmatic declines and extirpation of L. getula populations elsewhere, at Rainey Slough the primary cause likely was unsustainable mortality from road reconstruction and paving in the winter–spring of 1979 and subsequent roadkill. Other potentially causative agents of extirpation of L. getula in this system are discussed.","PeriodicalId":56309,"journal":{"name":"Herpetological Monographs","volume":null,"pages":null},"PeriodicalIF":2.5,"publicationDate":"2017-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1655/HERPMONOGRAPHS-D-16-00006.1","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46897502","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At its center lies Wallacea (the transition between the terrestrial biotas of the Asian and Australian tectonic plates) and the Indonesian Throughflow (nexus of the equatorial marine biotas of the Indian and Pacific oceans). The aim of this study was to elucidate the role of paleogeography, paleoclimatology, and oceanic currents in the evolution and distribution of sea kraits across these major biogeographic crossroads and beyond. A recent assessment of times of taxonomic divergence was projected against paleogeographic reconstructions to produce a parsimonious, hypothetical model of events critical for the origin, dispersal, and differentiation of this taxon. Times and degree of divergence of taxa suggested by recent morphological and molecular studies are in accord with various climatological and geologic events. The model postulates that the distribution of sea kraits was neither greatly affected by tectonics, other than the approach of the Australian Plate to the Asian one, nor dominated by the historic barriers to dispersal of terrestrial fauna across Wallacea, or by the Indonesian Throughflow. Rather, the model suggests that two major factors—paleogeographic alteration of the configuration of land and sea, and the directions of sea currents, past and present—provide an explanation of how these amphibious snakes (1) originated from a terrestrial Asian elapid ancestor, (2) subsequently generated the venomous Australian land snakes and their derivatives the true sea snakes, and (3) differentiated into the species complexes, species, and infraspecific entities of the genus Laticauda.","PeriodicalId":56309,"journal":{"name":"Herpetological Monographs","volume":null,"pages":null},"PeriodicalIF":2.5,"publicationDate":"2017-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1655/HERPMONOGRAPHS-D-16-00003","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43229947","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Phylogenetic analyses rely on ~7000 base pairs of mtDNA and nuDNA sequences aligned using similarity-alignment and tree-alignment and optimized under maximum likelihood and parsimony criteria. Inferred relationships place Lynchius as the sister group of the widespread genus Oreobates and this clade as the sister group of the high Andean genus Phrynopus. Our analyses corroborate the dissimilar species Lynchius simmonsi as part of this clade and place it as the sister group of the remaining species of Lynchius. Parsimony and maximum likelihood analyses differ in the internal relationships of Lynchius with respect to the placement of L. flavomaculatus, L. nebulanastes, and L. parkeri, but support the existence of two unnamed species. External morphological comparisons provide diagnostic characters for the two new species, which are named and described herein. Lynchius tabaconas is sister to L. flavomaculatus and occurs at ~2800 m in the cloud forests of Santuario Nacional Tabaconas-Namballe, Cajamarca, Peru. Lynchius oblitus occurs in the same area but at a higher elevation (~3300 m) and is sister to a clade formed by L. flavomaculatus and L. tabaconas in parsimony analyses and to L. nebulanastes in maximum likelihood analyses.

Toad embryos are often employed as model organisms, and scarce attention has been put on interspecific variations. In this work we analyze the development of transient embryonic and larval structures in 21 species in five genera of Bufonidae. These species vary in their ovipositional mode and the type of environments where the embryos and tadpoles develop, including ponds, streams, and axils of leaves of terrestrial or epiphytic plants. Comparative anatomical studies and sequence heterochrony analyses show that primary morphological variations occur in the morphology at the tail-bud stage, the arrangement and development of the external gills, adhesive gland type and division timing, growth of the dorsal hatching gland on the head, configuration of the oral disc, emergence and development of the hind limbs, and presence of the abdominal sucker. Some of these transformations are best explained by phylogeny (e.g., early divergent taxa of bufonids have embryos with kyphotic body curvature, Type C adhesive glands, and a very small third pair of gills). Other traits might be correlated with reproductive modes (e.g., phytotelmata embryos hatch comparatively late and show an accelerated development of hind limbs). Because these actual variations are not well studied (e.g., less than the 10% of the known diversity of bufonids has been studied from this perspective), comprehensive analyses are required to interpret character evolution and the relationship with reproductive modes within the family.","PeriodicalId":56309,"journal":{"name":"Herpetological Monographs","volume":null,"pages":null},"PeriodicalIF":2.5,"publicationDate":"2016-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1655/HERPMONOGRAPHS-D-16-00004.1","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67432190","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With the current background of global environmental change, studies of how habitat alteration affects local communities often focus on species' responses to community-level changes instead of responses to specific ecological factors that elucidate the roles each factor plays in the final synergistic response. Here, we focus on the specific ecological mechanisms that drive changes in community structure. We investigated compositional patterns of lizard communities among natural and altered habitats (vegetatively sparse, natural, and dense) in the desert steppe ecosystem of Inner Mongolia, China. Habitat alteration induced significant changes in community composition of lizards and was associated with significant changes in both biotic and abiotic niches. Our preference (soil, thermal, and prey) and performance (locomotor, antipredator, and competitive) experiments identified many of the biotic and abiotic factors shaping lizard community responses to habitat change. In the natural habitat, where Phrynocephalus frontalis and Eremias multiocellata codominate, P. frontalis experienced low overlap (across lizard species) in preferred prey. Eremias multiocellata preferred the thermal environment of the natural habitat (and dense habitat), but this one factor did not fully explain its codominance. Phrynocephalus frontalis dominated in the sparse habitat, where this lizard species experienced its preferred tight soil and warm thermal environment and experienced low overlap of preferred prey. In the dense habitat, where E. argus dominates, P. frontalis and E. multiocellata exhibited impeded locomotor performance, whereas E. argus was not impeded by vegetation density. Eremias argus also preferred the thermal environment of the dense habitat (and natural habitat). Our results suggest, furthermore, that adult predation risk was not a major determinant of community divergence among habitats and that competition likely plays a more important role. Interspecific competition for microhabitat use may explain the low abundance of E. argus in the natural habitat and the low abundance of P. frontalis in the dense habitat. Overall, our assessment of lizard preferences and performances explained community composition across habitats. Our focus on ecological mechanisms associated with habitat alteration highlights the importance of vegetation conservation in lizard community management.","PeriodicalId":56309,"journal":{"name":"Herpetological Monographs","volume":null,"pages":null},"PeriodicalIF":2.5,"publicationDate":"2016-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1655/HERPMONOGRAPHS-D-14-00008.1","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67432052","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
