Ronan Marrec

Ronan Marrec is a Full Professor at the University of Picardie Jules Verne, affiliated with the Faculty of Sciences and CNRS research unit UMR 7058 EDYSAN (Ecology and Dynamic of Anthropogenic Systems). His research examines spatial and temporal dynamics of human-modified landscapes and their impacts on biodiversity across multiple scales, integrating field studies, remote sensing, and ecological modeling.

Education

• Doctor of Biology, Ecology and Agronomy (University of Poitiers)

Research Focus

Marrec's work centers on landscape ecology, functional traits, and community assembly in agroecosystems and forests. He investigates how agricultural practices, landscape connectivity, and microclimate heterogeneity influence species distributions and ecosystem services, with carabid beetles serving as key bioindicators. His methodology combines empirical field data with advanced spatial modeling techniques to address conservation challenges under global change.

Publication Trends

Recent publications (2023-2025) reveal consistent emphasis on non-equilibrium biodiversity dynamics, landscape connectivity modeling, and microclimate-buffering effects in forests. Key themes include species distribution responses to historical land use, impacts of agrivoltaism on soil biodiversity, and functional trait-based analyses of arthropod communities across European agricultural gradients.

Academic Leadership

Since 2018, Marrec has directed the Agronomy option of the DUT Biological Engineering program at Amiens IUT, teaching courses in General Agronomy, Soil Sciences, and Agroecosystem Management while maintaining active field research collaborations across France, Italy, and Canada.
