I am an evolutionary biologist with a strong interest in explaining variation in animal behaviour. The main model system for my research is the fowl (red junglefowl and domestic fowl).
My main current research questions is:
However, I am also interested in research questions that fall within the following areas:
Why do animals have personality? Despite the potential benefit offered by full plasticity in behavioural responses, we commonly find that behavioural responses are consistent within individuals over time and/or context. This consistent variation in behaviour among individuals is called 'animal personality'. I am interested in the proximate and ultimate questions surrounding the evolution of personality, such as why individuals have personality, and the consequences it has. Thus, my research seeks to provide answers relating to the evolutionary origin, development and maintenance of variation in personality. In my group we are currently particularly interested on the interplay between personality and social status, and the potential interplay between personality and variation in cognition. For the latter we investigate variation in, and links to variation in personality, in for example learning speed, cognitive judgement bias and optimism.
The fowl is a great model for research on animal personality for various reasons, for example, we know a lot about their behaviours, life-history, physiology and genetics, they are easily habituation to humans enabling close observations and handling. I primarily use the fowl as the model for my research on animal personality, but I also use other species (e.g. beetles, cows and more recently sticklebacks).
Sexual selection and sexual conflict –what predicts the outcome of a copulation? My previous research (and this is still a research interest of mine) investigated pre- and post-copulatory processes and mechanisms. In polyandrous species, the outcome of a copulation can be influenced by mechanisms occuring both before and after insemination, including competition over access to partners, partner choice, sperm competition and cryptic female choice. Further, sex-specific and counteracting responses may take place.
The fowl is particularly well-suited for studies of sexual selection because they are promiscuous and females store sperm in thousands of sperm storage organs for weeks creating intense sperm competition and the potential for cryptic female choice. And both sexes respond to this in sophisticated ways; males allocate sperm strategically dependent on a range of cues (e.g. their own status, female quality) and females by biasing their sperm use (e.g. by ejecting ejaculates from non-preferred males). How males allocate sperm strategically and females bias sperm use is however still unclear to us.
Kin recognition, genetic incompatibility and kin selection. Inbreeding, when closely related individuals breed, may impose costs to individuals. Particularly the sex investing most in the offspring (typically females) should consider avoiding this cost, which may create sex-specific responses to genetic similarity between partners. I am interested in how individuals are able to recognise genetic similarity, and how this affects decision-making.
The use of the fowl as a model species more generally. Beyond the research areas mentioned above, I believe that the red junglefowl and domestic fowl are exceptional models for a range of questions where an experimental approach is beneficial. This includes research using fowl to investigate olfaction in birds, as a model for bird vision, and as a predator to help improve our understanding of predator-prey interactions.
