Biography
Evolutionary ecologist with a background in life-history evolution and senescence. My research focus is on understanding impacts of environmental variation, including anthropogenic disturbance, such as infrastructure development, on animal populations and biodiversity in general. I have worked with a range of study systems including insects, plants, mammals and birds, and my particular expertise lies with sciurids.
Degrees:
Ph.D. in Ecology at the University of Aberdeen (2017)
B.Sc. (Hons) in Animal Biology at the University of Stirling (2013)
Abstract
Studies in natural populations are essential to understand the evolutionary ecology of senescence and terminal allocation. While there are an increasing number of studies investigating late-life variation in different life-history traits of wild populations, little is known about these patterns in social behaviour. We used long-term individual based data on yellow-bellied marmots (Marmota flaviventer) to quantify how affiliative social behaviours and different life-history traits vary with age and in the last year of life, and how patterns compare between the two. We found that some social behaviours and all life-history traits varied with age, whereas terminal last year of life effects were only observed in life-history traits. Our results imply that affiliative social behaviours do not act as a mechanism to adjust allocation among traits when close to death, and highlight the importance of adopting an integrative approach, studying late-life variation and senescence across multiple different traits, to allow the identification of potential trade-offs. This article is part of the theme issue ‘Ageing and sociality: why, when and how does sociality change ageing patterns?’

Abstract
The diversity and abundance of pollinating insects is declining on a global scale and urgent action is needed. This is a brief film about the importance of pollinators, what is being done in Norway to counteract pollinator decline, and how you can help. Together, we can make a difference.
