Competition Funded PhD Project (Students Worldwide)
Summary: Atlantic salmon are an iconic species that are ecologically and economically of great importance. This project will study the collective behaviour of migrating Atlantic salmon using a combination of field studies, mathematical modelling and data analysis. The project will evaluate whether collective behaviour has positive consequences on the fecundity and survival of Atlantic salmon and enables them to more effectively navigate their environment. Whether this creates tipping points in population abundance will be assessed by examining the potential for feedbacks among population size, group sizes and group function. The ultimate goal is to develop a mechanistic framework to predict the impact of altered habitats on the migration and population dynamics of Atlantic salmon in Scotland.
Core questions of the project will be:
How does group size affect navigational accuracy? Field work will be performed using an array of acoustic receivers to allow imaging of the migration of varying numbers of returning Atlantic salmon and investigation of how group decision-making impacts migration routes. How does group size influence ability to navigate novel challenges? The student will examine whether social behaviour alters the ability of salmon to cross human introduced barriers such as fish ladders or fishing traps. Will fishing strategies target certain types of individual and lead to evolutionary responses that may impact the migration? Computer simulations will utilize known patterns of fish movement in groups to examine how salmon respond to barriers and deployed passive fishing gears, and whether this will result in novel selection pressure on the species. How does collective movement influence population dynamics of Atlantic salmon? Informed by the results of the behavioural studies the final stage of the project will develop spatial metapopulation models that incorporate a feedback between population size and the ability of groups to navigate.
