Amphibian and Reptile Community Responses to Forest and Riparian Disturbance
… cryptic species such as amphibians and reptiles. Previous studies of herpetofauna within SMZs have focused on one or a few stream-associated species, and questions remain regarding variation among species or guilds and what role SMZs serve toward conservation of herpetofaunal diversity …

Conserving amphibian and reptile diversity in north Madagascar: Contributions from baseline herpetological survey work
Madagascar has long been recognized as one of the world’s priority global hotspots for biodiversity conservation. Its herpetofauna, in particular, is extremely species-rich and diverse with high levels of endemism. By far the most important threat to its continued survival is the relentless …

Amphibian and reptile conservation in a changing environment: Case studies from the southeastern United States
… challenges currently facing imperiled species of reptiles and amphibians in this region. The work is focused on two species, the Reticulated Flatwoods Salamander (Ambystoma bishopi) and the Eastern Indigo Snake (Drymarchon couperi) both of which are listed on the U.S. Endangered Species List. …

Sex Determination And Differentiation In The Common Snapping Turtle - A Reptile With Temperature-Dependent Sex Determination
… differentiation in the common snapping turtle, a reptile with TSD. </p> <p> I used differential-display PCR to clone a candidate gene involved in TSD, the cold-inducible RNA binding protein (Cirbp). The temporal and spatial patterns of Cirbp mRNA and protein expression during and after sex …

Fish and Reptile Remains From the Late Eocene, Crow Creek Local Fauna, St. Francis County, Arkansas
A diverse late Eocene, lower vertebrate fauna is described based on collections made at the Crow Creek Quarry, in St. Francis County, Arkansas. Many of the taxa are reported from the late Eocene deposits of Arkansas for the first time. Paleoecological conditions evidenced by the vertebrate remains …

Rapid and portable molecular detection tools for reptile pest priority species in Australian environmental biosecurity scenarios
… invasive alien species into novel environments. Reptiles are considered particularly high risk, with many global examples of their detrimental impacts on both local environments and economies. The trade in exotic pets facilitates the transport of non-native species, which can lead to the …

Assessing the climate change vulnerability of reptile and amphibian species found in Table Mountain National Park
… focusing on the climate change vulnerability of reptile and amphibian species found in Table Mountain National Park (including historically present species). The park and its immediate surrounding areas are home to a rich diversity of herpetofauna including the Critically Endangered Table …

The impact of overgrazing on reptile diversity and population dynamics of Pedioplanis l. lineoocellata in the southern Kalahari
Die Vegetationskomposition und –struktur, beispielsweise die unterschiedliche Architektur von Bäumen, Sträuchern, Gräsern und Kräutern, bietet ein großes Spektrum an Habitaten und Nischen, die wiederum eine hohe Tierdiversität in den Savannensystemen des südlichen Afrikas ermöglichen. Dieses …

Quantitative Taphonomy of a Triassic Reptile: Tanytrachelos ahynis from the Cow Branch Formation, Dan River Basin, Solite Quarry, Virginia
The Virginia Solite Quarry assemblage of Tanytrachelos ahynis, with its exceptionally abundant and uniquely preserved specimens, offers an opportunity to quantify multiple aspects of vertebrate taphonomy. The presence or absence of 128 skeletal elements (i.e., bones) as well as the presence or …

Body Size Histories in Cenozoic Reptiles From Global to Community Scales
… relationship means that body size evolution in reptiles may be related to climatic change over time. In this thesis, I describe histories of maximum body size change in reptiles across the Cenozoic and examine which factors drive reptile size evolution at different scales. I characterize maximum …

AN OVERVIEW OF THE PET HERPETOFAUNA TRADE IN ENGLAND FROM 2016-2021
… was to attempt to quantify the herpetofauna (reptile and amphibian) trade across England and investigate the level of husbandry advice available for beginner owners. Over the past two decades there has been a large increase in keeping herpetofauna as pets and the UK trade alone is worth some …

A Mechanistic and Landscape Scale Approach Quantifying Habitat Suitability of Cheatgrass (Bromus tectorum) Engineered Habitats for Great Basin Reptiles
… the mechanisms driving these losses is lacking. Reptiles are an important component of this system and model organisms for elucidating the impacts of desert habitat modification. We established six paired study sites across three heavily invaded landscapes of northwest Nevada to quantify …

Molecular evolution of the p53 network in reptiles
… cells and other aging phenotypes. Because many reptile species have evolved unique organismal stress responses, we tested the related hypothesis that the evolutionary dynamics of, and mode of selection on, genes within the p53 network differs between reptiles and mammals, and that these …
