INSECT EVOLUTIONARY ECOLOGY
Our goal is to understand how evolutionary conflicts of interest shape animal lives. We use insects to investigate how conflict between mates, family members and social partners influences adaptation - in behaviour, morphology, life history, gene expression and molecular phenotypes.
We're part of the School of Biological Sciences at the University of East Anglia in Norwich, UK.
Currently recruiting! Please get in touch about studentships and postdoctoral positions.

RESEARCH
EVOLUTIONARY CONFLICT OVER ANIMAL NUTRITION AND DIET CHOICE
We want to understand how mating impacts nutritional state, and how evolutionary conflict shapes maternal diet choice and nutrition. We are investigating responses to diet in whole-organism phenotypes and molecular metabolomic phenotypes. We're asking these questions using fruit flies.
SEXUAL CONFLICT IN ECOLOGICAL CONTEXT
We are studying how ecological variation influences a sexual arms race in water striders.

CONGRATULATIONS, YASMIN!
August 2021
Congratulations to Yasmin, who finished her MSci and received a 1st, woohoo! Her project was titled 'Investigating vibrational signalling during male-male aggression in Drosophila melanogaster.'
ESCAPING THE CHOOSINESS TRAP
June 2021
Ben Hopkins and I wrote a News & Views about a terrific new study in Nature Ecology & Evolution, by Philip Kohlmeier, Jean-Christophe Billeter & colleagues. How can females avoid the choosiness trap? They need to be choosy enough to find the most superior males around, yet not set their standards so high that they reject all suitors. Our News & Views summary is available here - do email me for a pdf if it's paywalled for you.
HANGRY FRUIT FLIES: OUR NEW PAPER IS OUT
June 2021
Fruit flies: they're just like us. In this paper, the second from Dani's PhD, we show that being deprived of food makes male fruit flies more aggressive to each other. The paper is fully open access in Animal Behaviour here.
Dani was interviewed about it on BBC Breakfast TV, and it was covered in news outlets including these ones:
New Scientist
and in science news for kids at CBBC Newsround
CONGRATULATIONS DR EDMUNDS!

Very big congratulations to Dani, who defended her PhD! She got the most minor of minor corrections.
CEEC TWITTER CONFERENCE TALK
24 March 2021
I gave a twitter talk (my first!) as part of UEA's Centre for Ecology, Evolution and Conservation's twitter conference. I covered our recent work on aggression: its plasticity, microevolution and macroevolution

NEW PAPER: EXPERIMENTAL EVOLUTION OF AGGRESSION
17 March 2021
First paper from Dani's PhD! How are male and female aggression shaped by the intensity of local competition? We evolved flies under male-biased, female-biased, or equal sex ratios, and found that environments with more competition within a sex led to the evolution of more frequent aggression displayed by that sex.

CONGRATULATIONS LUKE!
August 2020
Luke successfully presented his MSc research and completed his dissertation. He documented shifts in phenology in UK ladybirds over recent decades in ways consistent with the UK's changing climate.
NEW PAPER: SEX, MATING AND ANXIETY
4 July 2020
‘Sex peptide’ – a male seminal protein in fruit flies – has big effects on many aspects of female behaviour, including things like aggression, sleep and memory formation. We wondered if sex peptide also regulates female anxiety. Fruit flies are a useful model for studying anxiety, so understanding how male and female anxiety is regulated in these animals might help us understand human anxiety and why anxiety is more common in women than in men.
Jess Thomson tackled this question for her undergraduate project. She used a standard assay of anxious behaviour: the extent to which individuals stick to the perimeter when they’re moving around their environment. It turns out that anxious individuals are more likely do this, in flies, rodents, humans and other animals. In our study, we found no evidence that males and females differed in their anxious behaviour, and no evidence that is influenced by either mating or sex peptide.
These results tell us that anxiety is not part of the big shift in behaviour that occurs after mating in female fruit flies. They also tell us that we need a different animal model to study sex differences in anxiety.

NEW PAPER OUT
January 2019
Our new paper, led by Juliano Morimoto and Grant McDonald, is out in Nature Communications here. Press release here.
In this study, we tested the idea that a higher female mating rate changes how sexual selection acts on males. We used fruit flies where females were genetically engineered to mate more often, such that we could experimentally control mating rate. We found that sexual selection was indeed changed by how often females mated. When they mated more, selection shifted to be stronger on post-copulatory traits that help males achieve fertilization, and weaker on pre-copulatory traits that help males achieve mating.
PHD PROJECTS AVAILABLE
Application deadline 25 Jan 2019
Three projects available. Please get in touch to discuss other projects of mutual interest.
