Uncovering Markers for Honey Production and Defensive Behaviour Using Pooled Genome-Wide Data with the Honeybee (Apis Mellifera)
… insect for both the study of social insect behaviour and agriculture. Honey production and defensive behaviour are honeybees two notable and economically valuable traits. Here we perform a genome-wide association study on 925 honeybee colonies from across Canada to elucidate the genetics of …

Effects of exogenous androgens on parental care behaviour in male bluegill sunfish (Lepomis macrochirus)
… mediated trade-off between nurturing and defensive behaviour during parental care. This research, however, comes from species with biparental care, where changes in behaviour of one parent can be compensated for by the other parent. I tested the validity of this trade-off by manipulating …

Local Variation in the Chemical Defence of European Pine Sawfly (Neodiprion sertifer): Effects of Host Tree Chemistry and Social Environment
… of pine needles, on the chemical defence and defensive behaviour of N. sertifer larvae and female oviposition decisions (group size and sex allocation). Additionally, I analysed how the social environment (group size and sex ratio) correlates with larval defensive traits. To study these, I …

Investigations into the relationship between behavioural tendencies and social status using the signal crayfish Pacifastacus leniusculus as a model organism
… that animals from a variety of taxa display behavioural tendencies which differ between individuals. If such tendencies are consistent over time and across contexts, they are generally referred to as personalities, temperaments or coping styles. Social conflict is believed to be one of the …

Spatial-memory control of defensive actions
Adapting anti-predatory defensive strategies to the properties of the environment is critical for survival. Here, I investigated the dependence of mouse instinctive defensive behaviours on memory of the spatial environment, and the neural mechanisms responsible for accurate escape towards refuge. …

Using the medical treatment contract as an instrument for replacing the tort liability system in England.
… duty of care and breach of that duty (negligent behaviour). The duty of care plays a crucial role as its violation is the foundation for establishing negligent behaviour. It is set through general principles, whose content cannot effectively encompass the diverse types of relationships between a …

Sociable weaver nests as a resource to local animal communities
… realised niche. Furthermore, pygmy falcon's defensive behaviour appears to deter predatory snakes from accessing a given colony. However, weaver reproductive output did not improve at falcon hosting colonies, suggesting falcon protection was offset by their predation of weaver chicks. Falcons …

The experience of dental avoidance
… influences on the development of avoidant behaviour, such as personal and family values, arise out of the historical and cultural milieu in which individuals find themselves. Acute influences from dental or non-dental experiences also effect avoidant behaviour. Growing out of these …

Role of the ventromedial hypothalamus in control of innate defensive behaviours
… such a variety of inputs to generate appropriate behaviours? Innate defensive behaviours are a good model to address this question. They are essential for animal survival and the brain circuits that control them are highly conserved across species. Moreover, the sensory inputs and behavioural …
