Use of personality to improve reintroduction success: the effects of behavioural variation within release groups
… differences in behaviour) is a growing area in behavioural ecology. The majority of studies have investigated the proximate or ultimate causes of these individual differences. However, there is growing interest in their practical applications, particularly to conservation. Previous studies have …

Individual risk and reward in the wild. A study on blue tits
Behavioural biologists seek to understand why individuals of the same species differ in their behaviour. The "pace-of-life syndrome" (POLS) hypothesis offers a framework to explain such individual behavioural variation. It puts forth that individuals differ broadly in how they take risks in their …

Non-structural Deterrents and Opportunistic Dispersal in an Invasive Fish: The Role of Among-Individual Variation on Common Carp Movement
… level of the individual, but among-individual variation in dispersal behaviour is rarely considered in aquatic conservation and invasion control. To address this challenge, my thesis applied concepts of behavioural ecology to invasion biology. Using an invasive fish, Common Carp (Cyprinus …

Variation drives response to urbanisation: Evolutionary ecology of two introduced birds within anthropogenic environments : A thesis submitted in partial fulfilment of the requirements for the Degree of Doctor of Philosophy at Lincoln University
… Such colonists should display a wide spectrum of behavioural, phenotypic, physiological and genetic modifications. Adaptively responding to novel stimuli is a major challenge for urban and rural wildlife and is linked with their fitness. These responses will likely differ between urban and rural …

Considering behaviour in genetic sampling – a case study with grey seals
Genetic variations are increasingly linked to intra-specific behavioural variations. Advancing our knowledge of behavioural genetics could make screening populations for genetic polymorphisms associated with behavioural variations possible. Genetic-behaviour links have been increasingly discovered …

Behavioural Ecology in Conservation Planning: Individual and Sex-Specific Insights from Woodland Caribou (Rangifer tarandus caribou) in Western Canada
… overlooking the continuous nature of adaptive variation. Individual behavioural diversity, shaped by genetic, environmental, and social processes offers an alternative lens for understanding population structure that reflects functional ecological strategies. This thesis explores how …

The evolution of mating systems in black scavenger flies (Diptera: Sepsidae)
… several species, I found pronounced geographic variation in the expression of this trait. I argue that sepsids share certain characteristics which may have facilitated multiple independent origins of escorting behaviour. In order to investigate the adaptive significance of escorting, I have …

Animal personality and the social context: the role of boldness and sociability variation in schooling fish
… their environment. In particular, consistent behavioural variation, known as animal personality, is a substantial driver of a range of important ecological and evolutionary processes. As most animal species are social for at least part of their lives and group living is common, a crucial link …

Tissue-specific behavioural signatures in cortical and trabecular bone. Variations in long bone structure in medieval Britain, and the differential effects of age.
… approach presumes a good agreement between such behavioural signatures in either tissue. Because cortical and trabecular structure are rarely studied together in an anthropological context, it is unclear how biological and structural differences between the tissues may affect the interpretation …

Medaka fish as a model for complex trait genetics
… one physiological (heart rate) and one behavioural (bold-shy behaviour). After providing an overview of the history of genetics and the current state of the art in Chapter 1, the main body of the thesis begins in Chapter 2 with a description of the computational methods I developed …

Foraging for a foothold: Causes and consequences of dietary variation in a threatened avian pollinator
… questions remain about why this intraspecific variation exists and what consequences it may have for individuals, populations, and ecosystems. This information may be particularly important for species that are threatened due to food limitation, as dietary variation could be used to inform …
