Current Research Topics

Due to their complex life cycle, diadromous fish are key witnesses of local and global ecosystem disturbances. Understanding the dynamics of these populations is a major scientific and societal challenge to ensure both their conservation and exploitation. In this context, my work aims to understand the response of salmonid populations to environmental changes. In particular, I am interested in explaining variations in life history traits by demographic mechanisms, with application for the management of Atlantic salmon and sea trout. Working with long-term monitoring and scale archives, I seek to reduce the uncertainty on empirical observations, to improve the description of inter-individual heterogeneity and inter-population comparisons. I combine population and individual approaches to study the effect of the environment on salmonids body size, age structure, migration decision and population dynamics. In particular, my aim is to explicitly consider individual growth at the core of Atlantic salmon life cycle to better understand the key constraints shaping demographic transitions and population responses to a changing environment, in freshwater and at sea.
