| rhinoclemmysnema n. g. and three new species of nematodes of the family atractidae (cosmocercoidea), with notes on the helminth fauna of rhinoclemmys pulcherrima (testudines: bataguridae) in costa rica. | rhinoclemmysnema n. g. and three new species of atractid nematodes, namely, atractis costaricaensis n. sp., orientatractis asymmetrica n. sp. and rhinoclemmysnema multilabiatum were recovered from the small and large intestine of rhinoclemmys pulcherrima, the painted wood turtle in the guanacaste conservation area, costa rica. the genera and three species are characterized by the features of the cephalic region and male tail. neopolystoma fentoni (conjuctival sac) and heronimus mollis (lungs) we ... | 2006 | 17125541 |
| the distal forelimb musculature in aquatic and terrestrial turtles: phylogeny or environmental constraints? | we compared the muscular anatomy of the distal front limb in terrestrial and aquatic chelonians to test whether observed differences between the two groups are associated with their divergent lifestyles and locomotor modes. given the different use of the forelimb in the two environments (body support and propulsion on land vs. mainly propulsion in water) we expected that: (1) aquatic and terrestrial turtles would show differences in their muscular anatomy, with aquatic species having more indivi ... | 2008 | 19172731 |
| neopolystoma fentoni n. sp. (monogenea: polystomatidae) a parasite of the conjunctival sac of freshwater turtles in costa rica. | neopolystoma fentoni n. sp. is described from the conjunctival sac of kinosternon leucostomum (duméril, bibron, and duméril 1851) and rhinoclemmys pulcherrima (gray 1855) from the guanacaste conservation area in costa rica. the new species differs from all other species of neopolystoma, except n. elizabethae platt 2000 in possessing a circle of eight genital spines that are recurved and possess a crescent-shaped base. n. fentoni n. sp. differs from n. elizabethae in lacking cecal diverticula and ... | 2006 | 11080769 |
| a diversity and conservation inventory of the herpetofauna of the cuautlapan valley, veracruz, mexico. | we compiled an inventory of the amphibians and reptiles of the cuautlapan valley, veracruz, mexico based on field surveys and museum and literature records. we found a total of 78 species: 28 amphibians (6 salamanders and 22 anurans); and 50 reptiles (three turtles, 18 lizards, and 29 snakes). these taxa represent 26 families (eight amphibian families, 18 reptile families) and 60 genera (19 amphibian genera, 41 reptile genera). two of these species are not native to the area (rhinoclemmys pulche ... | 2016 | 27988584 |
| the dorsal lingual epithelium of rhinoclemmys pulcherrima incisa (chelonia, cryptodira). | this study employed light microscopic (lm), scanning electron microscopic (sem), and transmission electron microscopic (tem) methods to provide detailed morphological information on the histological and ultrastructural features of the dorsal tongue epithelium of rhinoclemmys pulcherrima incisa. sem revealed columnar papillae laterally, as well as papillae, which tend to have a ridge-like appearance in the center of the tongue. lm and tem showed three different zones of lingual epithelium: a stra ... | 2004 | 14983517 |
| effects of brodifacoum and diphacinone exposure on four species of reptiles: tissue residue levels and survivorship. | anticoagulant rodenticides are used worldwide to control pest rodent species. however, the risks posed to non-target reptiles have not been well characterized. in this study, 46 giant ameivas (ameiva ameiva), 39 boa constrictors (boa constrictor), 33 wood turtles (rhinoclemmys pulcherrima), and 47 green iguanas (iguana iguana) were orally dosed with one of two levels of either diphacinone or brodifacoum anticoagulant in propylene glycol solutions. dosages were derived using daily food intake (df ... | 2020 | 31858711 |
