The Team

THE ANIMAL SOCIETIES TEAM

Andy Young
Associate Professor of Evolutionary Ecology

I am an evolutionary ecologist with particular interests in social evolution and senescence (ageing), and my team study both via long-term field studies of wild social vertebrates, including cooperative weaver birds in the Kalahari desert and European badgers in the UK. We also collaborate with microbiologists to study the evolutionary origins of ageing in unicellular organisms using timelapse microfluidics. We ask both evolutionary and mechanistic questions, given the potential for each to inform the other.

I am also co-Director of Research in Exeter’s Centre for Ecology & Conservation, working to promote supportive, inclusive and open research culture. I am also Programme lead for our flagship MSc Programme in Evolution, Behaviour and Ecology and a peer-mentor for early-career researchers and staff.

I started my career in Cambridge, completing my Honours degree and PhD, and then holding a Fellowship at Magdalene College. I then won a NERC Fellowship to move to Exeter’s Centre for Ecology & Conservation in 2007 and set up the sparrow weaver project in the Kalahari desert, followed by a BBSRC David Phillips Fellowship in 2010. I have since complemented our Kalahari work with a long-term collaboration with the Animal & Plant Health Agency, using their 50-year longitudinal study of European badgers.

Away from the office, I am a climber, kayaker, photographer, mammalwatcher and father of twins.

Will Singleton

PhD candidate
The Evolution and Mechanisms of Ageing in Unicellular Organisms

Will’s research combines empirical work (using timelapse microfluidics to study cellular life-histories) with evolutionary modelling, to shed light on the origins of ageing in our most distant ancestors.

Co-supervisors: Stefano Pagliara, Bram Kuijper & Angus Buckling

Jess Briner

PhD candidate
Thermal tolerance & performance
of an arid-zone bird in a warming world

Jess’ research is using core body temperature loggers and our long-term data to investigate physiological and fitness consequences of climate change in our desert-living sparrow-weavers.

Co-supervisors: Andrea Fuller
(University of Witwatersrand)

Tasha Hammond

PhD candidate
Drivers of microbiome variation
in European badgers

Tasha’s research investigates the drivers of microbiome variation in European badgers and their environments, seeking to shed light on the role of badgers in transmission of bovine TB and antimicrobial resistance genes.

Main supervisor: Xav Harrison
Co-supervior: Dez Delehay (APHA)

 

RECENT GRADUATES

Melanie Weedon

NERC PhD 2023
Senescence and Parental age effects
in wild European badgers

Mel studied parental age effects and the ageing of the inflammatory immune system in wild European badgers.

Mel discovered…

- Early severe maternal age effects on offspring lifetime reproductive success

- Paternal age effect arising from a terminal effect of father’s last year of life

- Compelling evidence of inflammageing and its fitness consequences in the wild

Antony Brown

BBSRC PhD 2022
Mechanisms of age-related changes in performance in a cooperative bird

Ant studied parental age effects, telomere biology & cellular senescence in sparrow weaver societies.

Ant discovered…

- That senescent cells triggered by telomeres do not accumulate in the wild

- Positive effects of parental age on offspring telomere length

- That the oldest birds dominate reproductive competition, with implications longevity evolution

Pablo Capilla Lasheras

BBSRC PhD 2020
The Evolution of Cooperation in Variable Environments

Pablo studied the evolution of cooperation & maternal plasticity in Kalahari sparrow weavers.

Pablo discovered…

- That helping reduces rainfall-induced variance in reproductive success, as envisaged under altruistic bet-hedging.

- That sex differences in cooperation can arise from trade-offs with dispersal

- That mothers plastically increase egg size when they have more help
