Edel Lheureux works on a Bayesian model of the life cycle of a wildlife population of Atlantic salmon (Salmo salar). She studies the evolution of the phenology of migration of this population during the last 15 years, linked with the environmental conditions. Then, these results will be used to make some projections of the population dynamic in the context of the climate change .
Keywords: modelling, phenology, Atlantic salmon, climate change, population dynamics.

Mélanie Debelgarric is specialized in modelling of ecological systems. Her thesis research focuses on the role of bioenergetic mechanisms as evolutionary constraints when facing stochasticity and extreme events. For that, she uses the Dynamic Energy Budget (DEB) model theory and genetic models to predict the impact of global changes on freshwater individuals and populations.
Keywords: environmental variability, modelling, phenotypic plasticity, bioenergetics, DEB theory.
Stellia Sebihi started her thesis in October 2021. She studies the role of stress and the effects of a benzodiazepine (Diazepam) on the facultative migration of the European glass eel (Anguilla Anguilla). This involves carefully planned experiments allowing to pinpoint how toxics may modify the finely tuned internal clocks controlling swimming activity in glass eels.
Keywords: Facultative migration, experimental ecology, glass eel, stress, benzodiazepine.
Léa Daupagne started her thesis in September 2020. She studies the structure and the dynamic of mating networks in lampreys throughout the breeding season by combining both an empirical and a theoretical approach. This will notably include studying the prezygotic reproductive isolation between closely-related parasitic and non-parasitic species.
Keywords: mate choice, sexual selection, multilayer network analysis, polygynandry.
Loïc Baumann focuses on unravelling the ecology of the first life stages of shads (Alosa alosa), and on assessing to what extent these stages are sensitive to various environmental degradations, such as habitat modification or hypoxia events. Loïc investigates in particular the behavioural and stress responses to these factors.
Keywords: behaviour, ecology, conservation, restoration, stress, shad.
Marius Dhamelincourt studies the mating systems in lampreys species, using in natura observations and experimental approaches. He also investigates the relationship between habitat and mating behaviour, and the impact on the ecosystem.
Keywords: reproductive system, experimental ecology, lampreys.
Amaïa Lamarins works on the portfolio effect in Atlantic salmon metapopulations, using the demogenetic model IBASAM. She studies how the metapopulation structure can bolster the resilience of populations through dispersal, local adaptation and management practices.
Keywords: demogenetic, modelling, metapopulations, salmon.
Dorinda Folio works on the dynamics of hybridization between Atlantic and Mediterranean lineages of brown trout. She’s developing an individual based model simulating the demogenetic dynamics of populations, accounting for both management actions (fishing, restocking, connectivity) and evolutionary feedback.
Keywords: demogenetic, modelling, biodiversity management, brown trout.
Lucie Aulus begins a thesis on the evolution of life history traits along a colonization gradient. She’s focusing on the case of growth and its effect on age at sea migration in introduced brown trout of the Kerguelen Islands.
Keywords: reaction norms, natural selection, long term monitoring.
Clément Lebot just started his thesis, he is focusing on wild Atlantic salmon management. Thanks to population dynamics modelling, he will evaluate the impact of different management strategies on Atlantic salmon conservation.
Keywords: population dynamics, stock recruitment, hierarchical modelling, sustainability.
Louise Chevalier started recently her thesis on the co-evolution of genome and traits or behaviour involved in sexual selection. Her approach is mainly theoretical and seeks to overcome the classical phenotypic gambit used in behavioural ecology.
Keywords: demogenetics, adaptive dynamics, sexual selection, mate choice
Hengtong Liu‘s thesis topic revolves around energy metabolism in European glass eel, and its effect on migratory behaviour. She develops an integrative approach from genes to behaviour, with a specific focus on autophagic mechanisms.
Keywords: migratory behaviour, transcriptomics, metabolism.
Elorri Arrevalo obtained her PhD in our lab, in co-supervision with Ecology Department of the University of Pays Basque in Bilbao. She investigated the possible match/mismatch hypothesis between salmonids and their macroinvertebrates feeding resources in the context of Climate Change, and thereby discharge and temperature dynamics modifications.
Status: PhD (2014-2017) – Now Postdoc at IRSTEA
Keywords: trophic interactions, salmonids, hierarchical modelling.
