The Physiological and Behavioural Consequences of Reduced Scalation in Captive-bred Phenotypes of the Bearded Dragon (Pogona vitticeps Ahl 1926)
… rates of evaporative water loss, the lowest thermal preferences, and the lowest UV light intensity preferences. By the same token, I expected Wild Types to be at the opposite end of the spectrum from Silkbacks for each of these measurements, and I expected Leatherbacks to be intermediate …

The thermal tolerances and preferences of native fishes in the Cape Floristic Region: towards understanding the effect of climate change on native fish species
… behaviour, and life-histories of aquatic biota. Thermal alteration may therefore affect sensitive fish species. The upper thermal limit, determined via the critical thermal method, has been validated as a measure of thermal sensitivity. To better understand the impacts of climate change on the …

Habitat Use and Spatial Patterns of a Cottonmouth Snake (Agkistrodon Piscivorus Leucostoma) Population and Thermoregulation of Male Cottonmouth Snakes in Southwestern Missouri
… and gaps within the forest canopy to accommodate thermal needs during gestation. The thermal preference range (Tset) of four male snakes was determined to be 23.5 - 29.5 oC with a mean temperature of 26.3 oC (+- 0.253). The mean body temperature of field-active males was 22.54 oC (+-0.028). …

Exploring Mosquito Thermal Biology and Chemical Ecology in the Context of Host-Seeking and Climate Change
… mosquitoes. The first project focuses on the thermal preference and response to thermal cues of three Culex species which vary in host preference and climate of origin. The second project explores the effects of different rearing temperatures and regions of origin on the thermal performance, …

Effects of annual thermal regime on growth trajectories of native age-0 brook trout (Salvelinus Fontinalis)
… such changes. Brook trout are considered stenothermal, with a thermal preference of 14°C to 18°C, and a critical thermal maximum of 25°C. With such narrow thermal optima, brook trout are restricted to watersheds with adequate thermal refugia to withstand warm summer temperatures. For …

Personalized building comfort control
… environments. To date, the measurement of thermal preference has been limited to either a complex set of sensors attempting to determine a Predicted Mean Vote (PMV) value, or to direct polling of the user. The former is far too cumbersome and expensive for practical application, and the …

Biology, movement behaviour and spatial dynamics of an exploited population of smooth hound shark mustelus mustelus around a coastal marine protected area in South Africa
… spatial behaviour in relation to environmental preferences of Mustelus mustelus were studied in the Saldanha Bay region on the west coast of South Africa. The overarching aim of this thesis was to examine the biological and ecological circumstances under which a MPA could provide effective …

Latitudinal Variation in Thermal Tolerance and Preference of <i>Fundulus notatus</i> and <i>F. olivaceus</i>: Implications for Temperature Mediated Reproductive Isolation
… range, these populations inhabit a wide range of thermal regimes, thus having to locally adapt to their surrounding thermal environments. Variable temperature regimes along latitudinal gradients might be responsible for adaptive differences in thermal biologies among populations. I examined …

Behavioral freeze avoidance in an Antarctic fish
… the Ross Sea) lacked measurable AFGP activity or thermal hysteresis (TH). How it survives in the ice-covered Southern Ocean is unclear. Analyses of the sera of L. squamifrons from the West Antarctic Peninsula (WAP) confirmed that TH was indeed minimal or absent. The sera osmolality was 429 ± 19 …

Physiological and Behavioral Aspects of Thermoregulation in Diarrheic Piglets

Ecological consequences of genetically-based thermal traits in fishes

The influence of embryo incubation temperature on later life aerobic performance of Lake Whitefish (Coregonus clupeaformis) and Yellow Perch (Perca flavescens)
