PhD Studentship - Enhancing the adult escapement of migratory species to breeding areas from modified freshwaters in Europe: the case of the European eel

Migration aims to maximize the fitness of species in seasonal environments, especially where temporal changes in habitat quality are predictable. It exists in a trade-off with its costs, encompassing time, energy and mortality. Anthropogenic modifications to the environment (land-use change towards food production, modified rivers to increase hydropower generation) have resulted in many previously connected seasonal environments becoming disconnected, and with the seasonal predictability of the optimal conditions for reproduction becoming increasingly asynchronous with conditions in non-breeding areas. The net result is the costs of migration increase as the sexually mature adults are either unable to migrate easily to their breeding places and/ or the conditions they experience on arrival are sub-optimal for reproduction and/ or subsequent juvenile survival and recruitment.

 
The aim of this PhD is to work on appropriate critically-endangered model migratory species that face substantial challenges in the ability of their adults to emigrate from non-breeding to breeding areas. Using the European eel (emigrating silver eels) as the model species, the objectives (O) are to: 
O1. Apply biotelemetry methods to quantify the emigration phenology and ecology of eels emigrating from freshwaters and assess how environmental transformation impacts emigration costs; 
O2. Track the movements of these tagged migrating individuals using acoustic biotelemetry across their different environments to quantify migration routes, speed and timing; 
O3. Use data from O1 and O2 to identify how conservation by assisted migration could improve the ability of these individuals to migrate and reduce the migration costs.

This is a fully-funded PhD studentship which includes a stipend of £17,668 each year to support your living costs.
