The basking shark Cetorhinus maximus: movement, behaviour and connectivity in the Northeast Atlantic
… thesis addressed several key questions in the basking shark (Cetorhinus maximus) regarding surfacing behaviour and thermal ecology as well as, connectivity between recognised coastal sites for seasonal aggregation. This study focused on a seasonal ‘hotspot’ for basking sharks at Malin Head, …

New insights into the summer distribution of basking sharks (Cetorhinus maximus) in the northeast Atlantic
Basking sharks, Cetorhinus maximus, have undergone widespread historic exploitation in the northeast Atlantic and are of conservation concern. A greater knowledge on their spatial and temporal habitat use in response to environmental conditions is required to better inform subsequent monitoring and …

Inferences about the conservation utility of using unmanned aerial vehicles to conduct rapid assessments for basking freshwater turtles
… easy, efficient, and less invasive way to study basking turtles.

Impact of Human Disturbance on the Behavior and Physiology of the Endangered Ringed Sawback Turtle (Graptemys oculifera)
… turtles by disrupting thermoregulatory basking behavior. In this thesis I assess the behavioral and physiologic impacts of high boat traffic, reductions of basking structures, and environmental factors on basking behavior, rates of disturbance, thermoregulation, parasite load, shell …

Distribution, Habitat Analysis, and Conservation of the Timber Rattlesnake in Virginia
… regions and at more northern latitudes is basking habitat, which typically is an exposed rocky area used by gravid females for gestation, and by other timber rattlesnakes for shedding, mating, and digesting. Understanding the range of the timber rattlesnake in Virginia will enable …

Population and habitat ecology of the river cooter (Pseudemys concinna) in the New River Gorge National River, W.V.
… water (0-2m), aquatic macrophyte beds, and basking sites. The estimated adult population during summer 1985 was 64 individuals. Six, 25%, and 35% of the captures at the three study sites respectively, were juveniles. Most hatchling cooters apparently overwintered in the nest and emerged in …

Population Status and Trends of the Ringed Sawback (Graptemys oculifera) in The Pearl River Drainage of Mississippi and Louisiana
… likely the species’ recovery. Abundance levels, basking counts, and demographic parameters were measured from 2022-2024 at sites throughout the Pearl River drainage including five long-term monitoring sites. Population density estimates produced by two mark-resight models (Schnabel and NOREMARK) …

The behaviour and wing morphology of the meadow brown butterfly (Maniola jurtina L.) in Britain : the influence of weather and location
… influenced duration of flight, feeding and basking (butterflies in both regions used both dorsal and lateral basking postures), with the largest effects being shown for the southern popUlation. Males from both regions flew for significantly longer than females and northern males flew for …

“I Pledge Allegiance”: Examining Motivations for Sport Fanship and Fandom in the American South
… identification, fan identification, rivalry, Basking in Reflected Glory, Glory Out of Reflected Failures, and state pride are all present. Family, social viewing, age, as well as many other motivations, emerged as strong motivating predictors.

Ecology and morphology of the Kalahari tent tortoise, Psammobates oculifer, in a semi-arid environment
… as refuges in cool months, probably to maximise basking whilst remaining in protective cover. During hot periods, mammal burrows were preferred to vegetation as refugia. The smaller males spent more time in cover than females, which may be related to predator avoidance or thermoregulation. …

Invertebrate Fauna of the Carapaces of the Texas River Cooter (Pseudemys texana) and the Red-Eared Slider (Trachemys scripta elegans)
… August through November 2002 using hoop nets, basking traps, and dip nets. Invertebrate samples were obtained by scraping a small area of the carapace to completely remove the algae and accompanying invertebrates and by brushing through the algal covering to remove invertebrates from the entire …

Geographical Distribution and Morphometrics of South Dakota Turtles

Spatial structuring in trait variation in Polyommatus icarus in a functional context
… determination of heating rates in different basking positions and thoracic temperature at take-off revealed no strong relationships of the morphological characteristics with heating or cooling rates and an indication of relationship with PGI alleles. It is suggested that m comparison to …

Influence of Ultraviolet Light, Righting Response, and Community Structure in Aquatic Turtles
Turtles are exposed to UV-B rays through basking, and since vitamin D3 is essential to the uptake of dietary calcium, UV-B light is considered important for growth in these animals. I studied the effects of UV-B light bulbs on growth in slider turtles (Trachemys scripta: N = 243) from hatching to …

Movements and oceanographic associations of large pelagic fishes in the North Atlantic Ocean
… I constructed track estimates for a large basking shark tag dataset using a high-resolution oceanographic model and discovered a wide range of movement strategies. I also applied this modeling approach to track archival-tagged swordfish, which revealed affinity for thermal front and eddy …

The Role of Temperature in Habitat Selection by Eastern Massasauga Rattlesnakes (Sistrurus Catenatus Catenatus) Near Their Northern Range Limit
… by using sites with little forest cover and basking more when environmental temperatures were very low. Males and nongravid females did not make similar adjustments, and in fact used more ground cover (hindering thermoregulation) when environmental temperatures were very low. Gravid females …
