Understanding Temporal Movement Behaviour Patterns: Measurement, Epidemiology, and Cardiometabolic Health Implications
… regarding the temporal patterning of these movement behaviours. Wearable devices have enabled researchers to explore such movement patterns at a time-resolution not possible using self-reported data. However, the substantial and growing number of metrics and methods used to study movement …

The basking shark Cetorhinus maximus: movement, behaviour and connectivity in the Northeast Atlantic
… 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, Ireland. In Chapter 2 we used data collected by time depth …

Effects of morphology, habitat and weather on the movement behaviour of range-expanding butterfly species
… It is therefore crucial to understand species’ movement behaviour and how it is affected by environmental variables to plan effective conservation measures for a wide range of species. This thesis aimed to enhance the current understanding of the role of dispersal in enabling species to respond …

Movement behaviour of the Green Jobfish (Aprion virescens), the Potato Bass (Epinephelus tukula) and the Giant Trevally (Caranx ignobilis), on South Africa's coral reefs
The movement behaviour of three important reef fish predators, namely potato bass (Epinephelus tukula), green jobfish (Aprion virescens) and giant trevally (Caranx ignobilis), were studied to provide information for marine spatial planning and to understand their ecological roles on South Africa's …

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
Aspects of the life-history, movement in relation to a Marine Protected Area (MPA) boundary, and short and long-term 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 …

Movement patterns of African elephants (Loxodont africana, Blumenbach) in a seasonally variable ecosystem in south-eastern Chad
… in a rapidly changing world. The study of movement has greatly advanced in the past few decades and novel approaches for characterizing and interpreting complex movement data, predominantly collected through telemetry, have emerged. The Zakouma National Park elephant population has declined …

Adaptive Spline Method for the Assessment of Cell Motility and its Application to Lesions
… to contain. Measures to stimulate or inhibit movement of cancer cells may play an important part in metastasis biology. The movement behaviour of individual cells within a cluster may give new clues about cell-to-cell interactions. However, the recognition and tracking of individual cells in …

Large and small-scale movement patterns of the West Coast rock lobster, Jasus lalandii
… focus of this thesis was to investigate the movement patterns of the South African West Coast rock lobster, Jasus lalandii, using a diverse range of techniques. These were (1) an examination of long-term data from an ongoing tag-recapture program, (2) observations on rock lobsters in a …

Spatial and temporal dynamics of an exploited reef-fish population
… temporal dynamics. This thesis investigates the movement of galjoen and its fishery parameters, and evaluates the role of marine protected areas (MPAs) and alternative assessment strategies. A review of the literature shows that there are examples of resident behaviour, territoriality, nomadism …

Seed dispersal effectiveness of samango monkey (Cercopithecus albogularis schwarzi)
… species, plant fitness is dependent on the behaviour of its mutualists in (a) reducing seed mortality and (b) increasing the likelihood of future reproduction. The main aim of this thesis was to assess how intergroup variability in the feeding and movement behaviour of a highly social …

Applications of programmable MEMS micromirrors in laser systems
… the scanning micromirror dynamic resonant tilt movement behaviour. A novel actuator geometry is presented to experimentally investigate this influence, allowing a continuous variation of the initial AVC comb-offset angle through an integrated electrothermal actuator. The experimentally observed …

Modelling and Analysis of Individual Animal Movement
Movement is ubiquitous to almost all life with most individuals undergoing some spatial change across their lifespans. Understanding how and why animals move through and interact with their environment is therefore key in understanding some of the most open and pressing questions in science; from …

Understanding dyslexia by measuring eye-movements during reading.
… 2013), and, explored the nature of dyslexic eye movement behaviour by including both a chronological- age and a reading-age matched control group. In three silent sentence-reading experiments, eye movements were recorded from dyslexic and non-dyslexic readers. Using the boundary paradigm (Rayner, …

Modelling animal movement in heterogeneous environments: from statistical inferential models to individual-based models
Modelling animal movement in heterogeneous environments is challenging because organisms experience a complex suite of internal and external stimuli that operate hierarchically over multiple temporal and spatial scales. A fundamental goal of movement ecology is to relate the behaviour of animals to …

Compensation in movement behaviours following exercise of different intensities in older adults
… of this thesis was to assess compensation in movement behaviours of older adults following exercise. Participants (n=28, 69.7±6.5 years) completed the following exercise protocols in random order, one week apart: moderate continuous exercise (MOD), high intensity interval exercise (HI), and …

The Use of Social Gaze Cues in Real World Scenes

Auditory Displays and Assistive Technologies: the use of head movements by visually impaired individuals and their implementation in binaural interfaces
… auditory virtual reality. It is known that head movements in the presence of sound elicit changes in the acoustical signals which arrive at each ear, and these changes can improve common auditory localisation problems in headphone-based auditory virtual reality, such as front-to-back reversals. …

Spatial Navigation in Immersive Virtual Environments
Pedestrian movement studies in real environments have shown consistent statistical relationships between ‘configurational’ properties of spatial layouts and movement flows, facilitating prediction of movement from designs. However, these studies are at an aggregate level and say nothing about how …
