Agathe Leriche is a research scientist with the Mediterranean Institute of marine and terrestrial Biodiversity and Ecology (IMBE), and a lecturer with Aix-Marseille University in France since 2009. She works at the interface between biogeography, ecological modelling, landscape ecology an conservation ecology. Her research apply modelling approaches to the study of biogeographical mechanisms involved in the origin and dynamics of Mediterranean biodiversity and likely consequences of global change.

2001- 2004 : PhD in environmental sciences, chemistry and health, specialisation in marine ecology (Université de la Méditerranée, Aix-Marseille II, France)
2004 - 2005 : Research and Teaching Assistant (ATER) at Université Aix-Marseille II
2005 - 2007 : GIS Specialist, ENSIS-SCION, Biosecurity Unit, New-Zealand
2007 - 2009 : Postdoctoral fellow in ecological modelling and climate change, CSIRO, Forest Systems Science, Australia


Agathe Leriche’s recent research aims to identify the drivers of plant biodiversity around the Mediterranean basin and whether and how the structure, composition and dynamics of natural communities are affected by global changes (long-term and large spatial-scale patterns and processes). It seeks to integrate functional ecology, evolutionary ecology and biogeography to describe and explain how several facets of biodiversity (e.g., functional diversity versus phylogenetic diversity) are distributed in space. Her research aims to have implications towards a conservation framework.

She has also performed several researches devoted to ecology of invasions, and in particular the assessment through modelling approaches of biosecurity risks associated to insect pests, pathogens and weeds. She has been member of the Australian CRC (Cooperative Research Centre for National Plant Biosecurity) and is member of Pest Risk Mapping Group (international panel of modellers focusing on pest risk modelling practice). She still has interests in developing and refining ecological methods for estimating pest risk, and post-border pest management.

She is member of the Climond team involved in the not-for-profit initiative intending to share specially formatted environmental data for use in ecological modelling (species distribution modelling, species niche modelling, pest risk analysis and pest risk assessment, species vulnerability modelling, assessing biofuels and other crop potential and threats, climate change research ; https://www.climond.org).


She is responsible of the formation of the 2nd year of master « Ecological expertise and biodiversity management » of Aix-Marseille University (http://www.masterset.fr/sbe/m2p-parcours-eegb/).

She teaches GIS, spatial conservation prioritization, sampling design and ecological modelling principally to students of first and second years of Master SET BEE (http://www.masterset.fr/sbe/)

Students mentoring

2010-2015 Co-Supervisor of a PhD student, Virgile Noble (with Pr. F. Médail)
The PhD work focuses on Mediterranean macroecology and biogeography with spatial analysis of the diversity of plant groups (geophytes and phanerophytes) to assess the contribution of biogeographic analysis for the conservation of the flora on a regional scale. Using more than 2 million observations of plant available in the database of the CBNM, this project is oriented around three main themes : 1) Description and understanding of the floristic biogeographic structure at a regional scale (taking into account the richness, composition and endemism), 2) Evaluation of the sensitivity of flora face of global changes, 3) Application of the results to the problem of conservation of flora at the regional level.

2015 Co-supervisor of 4 MSc 1 students (4 months)

2013 Co-Supervisor of a Msc 2 student (6 months)

2011 Supervisor of a MSc 1 student (2 months)
