Biography

I completed my PhD (2012-2016) in the Conservation Science Group in Cambridge, studying the impacts of temperature on the behaviour and distribution of two range-restricted endemic birds, the Ethiopian Bush-crow and White-tailed Swallow. Since then, I have worked for the RSPB Centre for Conservation Science, leading two projects assessing the effectiveness of Higher Level Stewardship agri-environment schemes in delivering population recovery of threatened farmland bird species (2016-2018). I returned to the Zoology Department in April 2018 as a Research Associate in the Insect Ecology Group, investigating how a community of British butterflies respond to fine-scale changes in temperature. In July 2019, I joined the Conservation Evidence group, where I am leading the production of the evidence synopsis on interventions for terrestrial and freshwater invertebrate conservation.

Research

I am interested in the ecological determinants of species ranges, and the impact that human-induced changes are having on species behaviour and distribution. My current research focusses on the ability of within-reserve habitat management to create suitable microclimates for butterfly species in the UK. In the face of climate change, incorporating effective microclimate management into traditional habitat management on reserves is increasingly important, as creating a range of climatically suitable sites within the landscape may be crucial to allow cold-adapted species to persist in refugia, and to create "stepping stones" for warm-adapted species as they shift their range northwards to track climatic suitability. My study sites for this project are a network of Wildlife Trust and RSPB chalk grassland reserves in Bedfordshire, Cambridgeshire and Wiltshire.
