| susceptibility of two turtle species to eastern equine encephalitis virus. | two species of turtle collected in southern new england were inoculated subcutaneously with eastern equine encephalitis virus. the spotted turtles (clemmys guttata) developed viremia and neutralizing antibody after exposure to 3 logs or more of virus. viremia was not detected in the eastern painted turtles (chrysemys picta), and neutralizing antibody was detected in only 1 of 15 inoculated c. picta; however, since pre-inoculation serum was not obtained from this animal, the possibility of natura ... | 1980 | 6257935 |
| a mycoplasma species of emydidae turtles in the northeastern usa. | mycoplasma infections can cause significant morbidity and mortality in captive and wild chelonians. as part of a health assessment of endangered bog turtles (glyptemys muhlenbergii) in the northeastern us, choanal and cloacal swabs from these and other sympatric species, including spotted turtles (clemmys guttata), eastern box turtles (terrapene carolina carolina), wood turtles (glyptemys insculpta), and common snapping turtles (chelydra serpentina) from 10 sampling sites in the states (us) of d ... | 2015 | 25574806 |
| molecular phylogenetics of emydine turtles: taxonomic revision and the evolution of shell kinesis. | the 10 extant species of emydine turtles represent an array of morphological and ecological forms recognizable and popular among scientists and hobbyists. nevertheless, the phylogenetic affinities of most emydines remain contentious. here, we examine the evolutionary relationships of emydine turtles using 2092 bp of dna encoding the mitochondrial genes cyt b, nd4, and adjacent trnas. these data contain 339 parsimony informative characters that we use to erect hypotheses of relationships for the ... | 2002 | 11884163 |
| body temperatures of selected amphibian and reptile species. | ectothermic vertebrates are a diverse group of animals that rely on external sources to maintain a preferred body temperature. amphibians and reptiles have a preferred optimal temperature zone that allows for optimal biological function. physiologic processes in ectotherms are influenced by temperature; these animals have capabilities in which they make use of behavioral and physiologic mechanisms to thermoregulate. core body, ambient air, body surface, and surface/water temperatures were obtain ... | 2012 | 23082515 |

| three novel herpesviruses of endangered clemmys and glyptemys turtles. | the rich diversity of the world's reptiles is at risk due to significant population declines of broad taxonomic and geographic scope. significant factors attributed to these declines include habitat loss, pollution, unsustainable collection and infectious disease. to investigate the presence and significance of a potential pathogen on populations of critically endangered bog turtles (glyptemys muhlenbergii) as well sympatric endangered wood (g. insculpta) and endangered spotted (clemmys guttata) ... | 2015 | 25875510 |
| application of thin-plate spline transformations to finite element models, or, how to turn a bog turtle into a spotted turtle to analyze both. | finite element (fe) models are popular tools that allow biologists to analyze the biomechanical behavior of complex anatomical structures. however, the expense and time required to create models from specimens has prevented comparative studies from involving large numbers of species. a new method is presented for transforming existing fe models using geometric morphometric methods. homologous landmark coordinates are digitized on the fe model and on a target specimen into which the fe model is b ... | 2009 | 19222567 |
| clinal variation in body and cell size in a widely distributed vertebrate ectotherm. | bergmann's rule states that, among conspecific populations, individuals are larger in cooler than in warmer environments as a consequence of selection related to heat conservation. many of the most comprehensive assessments of bergmann's rule to date have examined clinal patterns in body size among species assemblages. our study is a more direct test of bergmann's rule because we examine the pattern within a single, widely distributed species. we examined geographic variation in body and cell si ... | 2004 | 15179585 |
| expression of a shiga-like toxin during plastic colonization by two multidrug-resistant bacteria, aeromonas hydrophila rit668 and citrobacter freundii rit669, isolated from endangered turtles (clemmys guttata). | aeromonas hydrophila rit668 and citrobacter freundii rit669 were isolated from endangered spotted turtles (clemmys guttata). whole-genome sequencing, annotation and phylogenetic analyses of the genomes revealed that the closest relative of rit668 is a. hydrophila atcc 7966 and citrobacter portucalensis a60 for rit669. resistome analysis showed that a. hydrophila and c. freundii harbor six and 19 different antibiotic resistance genes, respectively. both bacteria colonize polyethylene and polyprop ... | 2020 | 32752245 |
