We are seeking a PhD candidate with a strong interest in connecting fundamental science to real-world conservation outputs to identify the drivers of movement in shorebirds within the non-breeding season.
Arctic-breeding migratory shorebirds are particularly vulnerable to climate change. Even in their overwintering grounds they face a future of limited food availability, with sea level rise and anthropogenic changes to their habitat threatening their winter survival. Every year, thousands of islandica red knots migrate from the Arctic to North-western Europe. Many of these individuals moult in the Dutch Wadden Sea but while some opt to stay over winter, others will move to the intertidal zones of the UK, such as Liverpool Bay and the Wash. However, the connectivity of these sites is poorly understood, and individuals may differ in their tendency to move between them. Considering global declines in shorebird numbers, we must inform local conservation efforts by investigating the relative importance of UK sites within this intertidal network and improve our understanding of how individual movement contributes to the resilience of the population.
By joining an international collaboration between Liverpool John Moores University, the British Trust for Ornithology (BTO) and the Netherlands Institute for Sea Research (NIOZ), the student will use the first multi-national ATLAS tracking system to track birds in both the Wadden sea and UK intertidal zones. Movement tracking will be supplemented by colour-ring reading reports from a network of citizen scientists across sites. The project aims to investigate the mechanisms underlying movements of individuals between intertidal zones in their non-breeding area. As well as using state-of-the-art tracking methods, the student will receive training in personality assays and diet analyses (DNA metabarcoding) and will have the opportunity to visit to partner organisation, NIOZ, to engage in fieldwork in the Netherlands, as well as the UK.
