Alex’s project aims to evaluate the influence of river flow-induced disturbance, including extreme events such as flooding and droughts, on the ecology of river birds in Great Britain. He is using data from the British Trust for Ornithology’s (BTO) Waterways Breeding Bird Surveys (WBBS) and river flow archives to build species distribution models (SDMs) that relates river bird distributions to hydrological indices of river flow regimes. In particular, he has been developing an index of vulnerability to flow extremes and modeling the impact of climate change-induced changes in river flow on future bird distributions.
Alex’s current work is funded by a studentship awarded by the UK National Environment Research Council.
Alex previously studied Zoology at the University of Glasgow, where he participated in a number of tropical research expeditions as part of the university’s Exploration Society, before working as a Graduate Teaching Assistant for 6 months. He has since worked as a Species Text Author for the charity Wildscreen, to profile endangered species for their website, www.arkive.org, spent a year and a half coordinating conservation research projects in Botum-Sakor National Park, Cambodia, and worked for the RSPB to survey for Black Grouse in the Scottish Highlands.
