In the current ‘Era of the Anthropocene’, global human impact is fundamentally altering ecological processes on earth. Thus understanding and predicting how biodiversity will respond to environmental change has become one of the most pressing questions for ecological research. Biodiversity responses to global change are ultimately mediated by proximate behavioural processes of individual organisms, affecting energy intake and expenditure and exposure to risks, and ultimately the distribution and demographic performance of individuals. Movement in particular is a key behavioural response to environmental change determining shifts in the abundance and range of species, yet we still lack the ability to understand and predict in a robust way why, and where, animals move.
The goal of this PhD project is to build upon the exceptional opportunities offered by a large set of sub-second biologging (accelerometer, magnetometer) and GPS data collected by an ongoing large UK-France collaboration and an ANR-funded project running until 2020 (“Mov-It”), which yield sub-second movement paths with associated information on the detailed behaviour, individual state and energy expenditure of each individual, collected on over 100 individuals of five wild ungulate species and three domestic ones, from six contrasting study areas across France, to develop novel mechanistic, predictive models of individual and species responses to environmental change. This will be achieved by tackling three inter-related, incremental objectives. Firstly the student will quantify movement decisions and costs under different constraints (e.g. food, weather, disturbance); then incorporate the estimated costs functions into Agent Based Models and multi-objective optimisation functions (Pareto optimisation), to model and map the full set of biologically realistic movement strategies under environmental change in complex, real landscapes. Thirdly, the student will develop from the modelling results a scenario planning tool for managers and landscape planners, allowing to build predictive models of individual movements and population and species redistributions under different scenarios of environmental change and management decisions. These aims will be further facilitated by the availability of a rich set of biological knowledge on the demography, life history and ecology of the species obtained by the long-term study sites. Furthermore, the student will profit from novel statistical and mathematical methods which we have developed to handle such complex, big data and novel quantitative models of animal movement, and to include currencies such as movement costs. Most importantly, the project is based on the understanding that there is not one single solution, in a given landscape, that solves the complex cost-benefit problem facing a herbivore for choosing where to be, what to do, how long to stay, and where to move next. Thus we look forward to work with an enthusiastic, creative, dedicated student to solve this “Movement Rubik’s Cube”.
The project will be supervised by Anne Loison at Université Grenoble Alpes, and by Luca Borger at Swansea University. A total of 18 months will be spent at the LECA laboratoire, Université Grenoble Alpes – Université SavoieMont-Blanc, and 18 months in the Department of Biosciences, College of Science at Swansea University.
