Behavioural Ecology and Physiology Research Group
Learn more about the work of the group
The Behavioural Ecology and Physiology Research Group studies the functions, mechanisms and development of behavioural and physiological interactions between organisms’ and the environment. We use a range of approaches to address our research questions. These include observations of behaviour and physiology in the laboratory and in the wild with particular focus on social interactions, phenotypic plasticity, cognitive abilities, transgenerational effects and circadian rhythms. Our research includes analyses of energy metabolism and nutrition, methylation, neurophysiology, photosynthesis and climate change, gene expression, communication, and personality. Members of this group have published recent findings in high profile journals in their fields, including Genome Research, Biological Psychiatry, Proceedings of the Royal Society B, Animal Behaviour, Elife, Functional Ecology and Behavioral Ecology.

Colour polymorphism – more than just different colours
Colour polymorphism describes the occurrence of different colour morphs in the same population and is a widespread phenomenon in vertebrates. Such variation is difficult to explain from an evolutionary point as all morphs need to be in equilibrium to persist over time. Colour morphs often differ in behaviours and physiological traits due to different predation pressures and social attractiveness. The Gouldian finch is polymorphic in its head colour with about 70% black-headed birds, 30% red-headed birds and less than 1% yellow-headed birds in a population. Research in our BEP group has shown that the birds signal their personality (representing consistent differences in behaviour between individuals) with their head colour; red-headed birds are more aggressive but less explorative and risk-taking than black-headed birds. Recent research also found that head colour morphs respond differently to novel environments with red-heads being more willing to venture into novel environments than black-heads.

Communication in animal social groups
The daffodil cichlid fish lives in tightly knit cooperative groups which work together to defend their small territory and raise the young of the breeding pair. Conflict is common in these groups and understanding how these animals communicate with each other when disputes arise is essential to understanding how these groups are formed, structured, and maintained. Recent work in the BEP group has shown that when threatened aggressively by a group mate, subordinate fish may tilt their heads up in the water column and give a little shake. This head up display serves as a submission signal and reduces the likelihood of further aggression. Whether or not this signal is produced depends on the social status, sex, and relative size of the interacting fish, as well as the physical structure of their territory. e.g., see: http://doi.org/10.1016/j.anbehav.2019.06.026
Hibernation comes with costs
Many mammals survive the cold winter months by lowering body temperature and their energy expenditure during hibernation. The lower their body temperature, the more energy hibernators can save. However, hibernation also comes at costs. A recent study has found that the lower the body temperatures during hibernation the faster the rate at which the protective endcaps of their chromosomes shorten, which can lead to cell death and may reduce the lifespan of the animal. These findings could explain why many animals in good body condition try to keep a warmer body temperature during hibernation, although this costs them more energy.

Photoperiods and Nasonia
Circadian rhythm studies of Nasonia (a small species of parasitoid wasp) have shown that changes in photoperiod lead to changes in DNA methylation which in turn affect diapause. This provides important insights into the molecular mechanisms that underpin responses to changing day lengths. See Genome Res. 2016;26(2):203-210. doi:10.1101/gr.196204.115.
The mammalian brain and circadian rhythms
Collaborative research involving members of the group provided the first description of circadian time-keeping properties in the subfornical organ of the mammalian brain, an area critical to the control of thirst and drinking behaviour. This work raises the possibility that the activity of this brain region may contribute to the daily regulation of drinking behaviour and osmotic regulation in mammals. See FASEB J. 2020 Jan; 34(1):974-987. doi: 10.1096/fj.201901111R.
Highly productive plants
It was not known until recently why the Mediterranean Giant Reed Arundo donax was so productive, growing up to six meters in one year. Paradoxically, it was found to be a less-efficient C3 photosynthesizing species but overcomes this through high levels of Rubisco activity. This plant has potential as a bioenergy species, and may hold insights into how to improve productivity in other C3 species in high temperature environments. For more information read the article: High C3 photosynthetic capacity and high intrinsic water use efficiency underlies the high productivity of the bioenergy grass Arundo donax.
Human environmental physiology
Our wide range of research topics also include human environmental physiology. For example, one area of investigation addresses the mechanisms by which stressors, the prenatal environment, energy availability, endocrine disrupting chemicals and social interactions affect reproductive function. Another recently instigated collaborative study project will investigate the impact of COVID-19 on quality of life, wellbeing, food intake and physical activity in cardiac rehabilitation patients.
