Kathryn joined the department in April 2010 as a Royal Society University Research Fellow. Prior to that, she held research positions at the University of Glasgow and University of Queensland.
Kathryn is an ecologist working mainly on the behavioural and physiological responses of vertebrates to changes in the environment. Her current research falls mainly into two areas: 1) the assessment of exposure to and effects of contaminants on wildlife and 2) the ecology of rural and urban birds. However, she also maintains an interest in the social behaviour of birds, insects, fish and manta rays. Her work has included projects in Australia, the Maldives, Malaysia and Scotland. Kathryn chairs the Environment Department's Ethical Review Committee and sits on the University's Athena Swan working group which aims to promote the interests of women in science.

Kathryn's research focuses on the impacts of social and environmental factors on behaviour, stress physiology, reproductive success, and susceptibility to oxidative damage. Current projects are investigating the effects of pollution and pharmaceuticals in the environment on vertebrates.
Previous studies have demonstrated the downstream impacts of early nutrition, driven for example by climate induced changes in prey abundance, on individual fitness. She is particularly interested in utilising state of the art techniques for measuring antioxidant levels, oxidative stress and disease prevalence in small vertebrates.

Individual variation in behaviour: Confronted with the same environmental or behavioural stressors, individuals of the same species often differ markedly in their behaviour. For example, some individuals are always more risk-prone or exploratory than others. We refer to these differences as "personality" traits Dr Arnold's group have been investigating whether these individual differences in behavioural responses are accompanied by variation in underlying stress metabolism and oxidative stress.

Maternal Effects: Reproduction is an expensive business. Mothers, in particular, put a lot of time and energy into making eggs and caring for young, at the expense of their own well being. Dr. Arnold has been investigating how mothers partition resources among young and how that affects the development and long term fitness of offspring. In birds, for example, mothers put substances into yolk that can influence the development of the egg. These include antioxidants, such as carotenoids (responsible for red and yellow colours in nature) and vitamin E, which enhance immune function and reduce the damage to organs caused by the build-up of harmful waste products. Parents also provide food to offspring. Selection of particular prey items might be vital for providing nutrients essential to normal growth. Dr Arnold's group use a range of avian model species to investigate maternal effects.

Sexual Signalling and colour preferences in birds: Fluorescence is widely used by humans as a 'highlighter' to attract attention. Research by Dr Arnold and colleagues shows that Australian parrots use their fluorescent plumage, which literally 'glows', to attract the attention of the opposite sex.

Sex Allocation in Birds: Ongoing research focuses on sex allocation in birds and fish. This started as a BBSRC funded project with Richard Griffiths and David Houston. There is increasing evidence that female birds manipulate the sex of their offspring in response to environmental and social factors. We have been investigating when and how this is achieved, mainly using the zebra finch (Taeniopygia guttata) and blue tit as models.
Kin Recognition in Fish: One of my main interests is the evolution of sociality and group living. Essential to this is determining whether animals are able to recognise individuals, particularly those that they are related to. Living with relatives can be beneficial to individuals via the evolution of kin-directed altruism, but this is tempered by the increased risk of inbreeding. Therefore, in social species the ability to recognise relatives can be highly advantageous. This study focused on kin discrimination in the Lake Eacham rainbowfish, Melanotaenia eachamensis, and cooperatively breeding cichlids.
