An innovative portable detector for the live-monitoring of radionuclides in small terrestrial animals
… radionuclide activity concentrations in small terrestrial animals. The detector is unique in that it enables field-based measurement of both gamma and beta emitting radionuclides (caesium-137 and strontium-90 are tested in this work) in living small animals. Literature on detector …

Food and Fortitude: A Story of Life Within Presidio San Saba as told through Zooarchaeological Analysis
… hunted versus domestic resources, aquatic versus terrestrial animals, element selection, butchery practices, size class, hunting practices and the potential consumptions of horses and bison.

Uncertainty analysis in ecological risk assessment modeling
… For the case of DU exposure to YPG terrestrial plants, the overall distributions for DU uptake for plants suggest 90% likelihood in reduction in root weight. For most terrestrial animals at YPG, the dose is less than that resulting in a decrease in offspring. At APG, DU exposure …

Home Field Advantage: Sprint Sensitivity to Ecologically Relevant Substrates in Lizards
… across variable substrates is important to all terrestrial animals. Much attention has been given to the effects of different substrates on locomotor performance in an attempt to link ecology and morphology. Sprint sensitivity is the decrease in sprint speed due to change in substrate. This …

Measuring terrestrial wildlife external radiation exposure under field conditions
… external radiation exposure of free-ranging terrestrial animals under field conditions. An evaluation of available passive dosimeter technologies was undertaken and guidance developed on the selection of dosimeters for different sizes of terrestrial animals. To test dosimeters under field …

Modeling contaminant transport and fate and subsequent impacts on ecosystems
… weight is considered likely to occur. For most terrestrial animals at YPG, the predicted DU dose is less than that which would result in a decrease in offspring. However, for the lesser long-nosed bat, reproductive effects are expected to occur through the reduction in size and weight of …

The Effects of Locomotor Posture on Kinematics, Performance and Behavior during Obstacle Negotiation in Lizards
… move over uneven terrain is critical for most terrestrial animals. Bipedal running is common in lizard species, however the biological advantage of a bipedal running posture remains uncertain. I examined the hypothesis that a bipedal posture is advantageous when crossing obstacles. …

Social behaviour of captive belugas, Delphinapterus leucas
… developed for investigating social behaviour of terrestrial animals were adapted for studying captive belugas, providing quantitative descriptions of social relationships .among individuals. Five groups of captive belugas were observed, allowing a cross-sectional view of sociality in groups of …

Structural colour in marine organisms: From nature to applications
… colour has been extensively studied in terrestrial animals and plants, marine organisms have begun receiving attention only recently. This thesis explores the prevalence and functional significance of structural colouration in seaweeds. By examining a variety of nano-architectures in …

Decisions Set in Stone: Spatial Analyses of Ozark Rock Art Sites, Elements, and Motifs with GIS
… celestial, and more “earthly” designs, such as terrestrial animals. Another observation suggests that certain anthropomorphic rock art were reserved for accessibility, while others were placed in relatively secluded locations. The results presented in this thesis potentially shed light on rock …

Scoping of Presence and Impacts of Tyre Wear Particles on Soil Systems
… their ecological effects on soil properties and terrestrial animals remains limited, calling for further investigation. In this study, Lufa 2.2 test soil and red topsoil sourced from Exeter were dosed with 0.1– 10% TWPs. Spiked soils were analysed for changes in pH, water holding capacity (WHC), …

Coastal resources and nutrition among Middle Stone Age hunter-gatherers in the Southwestern Cape
… and fatty acid content of marine and terrestrial resources available to Middle Stone Age hunter-gatherers in the southwestern Cape, and examines the role of coastal and terrestrial foods in the diets of early modern humans in the region. The collection, consumption and systematic …

CHARACTERIZATION AND PATHOLOGICAL STUDY OF A. HYDROPHILA IN WALKING CATFISH (CLARIAS GARIEPINUS)
… cells not only from fish but also from some terrestrial animals including man. They could grow in vitro at 37°C. This suggests that Aeromonas hydrophila isolated from fish could possibly cause zoonotic disease to other warm-blooded animals. The results also showed that extracellular products …

Characterizing the Role of Magnetic Cues Underlying Spatial Behavior
… responses to magnetic cues in laboratory animals (flies, mice) and the development of novel techniques for studying the role of magnetic cues in the spatial behavior of free-living animals (red foxes). Chapter II examines magnetic orientation in wild-type Drosophila melanogaster larvae. We …

Determination of the effects of pulse starches (pea, lentil and faba bean) versus cornstarch on growth performance and glucose tolerance in rainbow trout (Oncorhynchus mykiss)
… are the major energy source for humans and terrestrial animals. However, in fish, protein and lipid are more efficiently used for energy than carbohydrates. Despite this, stud-ies have shown that diets with an appropriate amount of carbohydrate improve growth in fish. Therefore, as a first …
