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 …

How animal movement defines behaviour: new insights into the ecology of seabirds at sea
How animals move through their environment defines their ecology at an individual and population level. All animals must search for food to survive and how they do this can be influenced by the world around them as well as their own internal state. Our understanding of animal ecology has been …

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 …

A Hybrid CUSUM approach to identify residency and transition periods for animal movement with an application to housed dairy cows
… advance in tracking technology which has allowed animal movement data to be collected with greater accuracy and in larger quantities. As a result, there has been a need for developing techniques to analyse this data and gather information such as bouts of foraging behaviour in wild animals, …

Our non-feathered friends: sensing and control in insect-scale flight
… we provide a resource for bringing together animal movement and linear control theory. Feedback control is a fundamental concept in animal movement, and to translate advances in biological understandings to engineered vehicles, we must be able to describe and compare the dynamics of …

A First Step Towards Understanding Sperm Whale Communication and Behavior
We present two tools for annotating and preparing animal audio and movement data for downstream modeling tasks. We present a modification of VisionTransformer which detects and classifies animal communication into an annotated format. We give a visualization tool to create estimates for animal …

Theoretical prediction of joint reaction force in a dynamic general 3-d pendulum tree model for human or animal motion
… and better understand the dynamics of human and animal movement as well as the forces associated with those movements. In particular, this work focuses on predicting the dynamic reaction forces that are produced in the simple idealized frictionless joints of the pendulum system during motion. The …

Roads and wildlife: a study of the effects of roads on mammals in roadside habitats
… and population dynamics. The large number of animal fatalities from road traffic accidents is also of concern. Only limited work has been carried out to investigate the intensity of these effects in the UK landscape. This study investigates the effects of roads on both small and large mammals …

Locomotor kinematics of turtles moving in shallow water environments
… in our complex world is as crucial to many animals as finding food, shelter or a mate. The intricate interplay between the brain, nerves, muscles, tendons and bones allows for a variety of gaits. Animal movement has been studied in many environments like water, land or air, often focusing on …

A Bayesian approach to discovery of latent dependency in point-referenced data
… a statistical model accounting for collective animal movement. The model highlights how to incorporate the ecological perspective into the hierarchical modeling structure, motivating the need of considering the underlying ecological structure to better understand the driving dynamics in the …

Biologging for marine megafauna conservation: animal tracking, environmental monitoring, and modelling approaches.
… Biologging—the use of electronic tags to study animal movement, behaviour, physiology—has emerged as a critical tool for understanding animal ecology and informing conservation strategies. This thesis explores the application of state-of-the-art biologging technologies to address major …

The Changing Place of Animals in Post-Franco Spain with particular reference to Bullfighting, Popular Festivities, and Pet-keeping.
This is a thesis about the changing place of animals in post-Franco Spain, with particular reference to bullfighting, popular festivities, and pet-keeping. The thesis argues that since the ‘transition’ to democracy (1975-1982), which made Spain one of the most liberal social-democratic states in …

Micro-doppler classification of humans and animals using FMCW radar
This research attempts to address the issue of animal poaching by exploring human and animal target classification by making use of micro-Doppler data generated by a Frequency-Modulated Continuous Wave (FMCW) radar. Raw Analogue to Digital Converter (ADC) data was collected of human and animal …

Research in motion: patterns of large-scale migration in dragonflies and birds
… temporal, and ecological basis to patterns of movement by highly vagile organisms. From this perspective, the differences between chapters are matters of scale: community versus population ecology, and movement by thousands of birds through two localities versus a study of a single invertebrate …

Barrier Effects Of Roads And Traffic On Animal Occurrence, Space Use, And Movements
… the world. Roads can act as barriers by impeding animal movement and restricting animal space use. An understanding of factors that influence barrier effects is important to discern the impacts of habitat fragmentation and to develop appropriate mitigation. The barrier effects of roads are driven …

Effects of added drag on cetaceans : fishing gear entanglement and external tag attachment
Animal movement is motivated in part by energetic constraints, where fitness is maximized by minimizing energy consumption. The energetic cost of movement depends on the resistive forces acting on an animal; changes in this force balance can occur naturally or unnaturally. Fishing gear that …

Fishery Interaction Modeling of Cetacean Bycatch in the California Drift Gillnet Fishery to Inform a Dynamic Ocean Management Tool
… the scales relevant to physical dynamics, animal movement and human use could be implemented. A key component to this approach is determining the factors that lead to fisheries interactions. Using 25 years (1990-2014) of National Oceanic and Atmospheric Administration fisheries’ observer …

A multi-scale study on the movement ecology of Afrotropical waterbirds
… the processes and mechanisms governing animal movement is a fundamental goal in ecology. Processes driving movement can occur across multiple spatiotemporal scales and have important consequences for the structure and dynamics of populations, communities and ecosystems. The study of …

Optimization of overhead enclosure monitoring software in a rodent model of osteoarthritis
