Welcome to the CEFE

The CEFE is currently the largest French research center in Ecology and Evolutionary Ecology. Our Mission: perform independent, fundamental scientific research on the dynamics of biodiversity, planetary environmental change, and sustainable development. The links between society and ecology is a theme of increasing importance in oour research.

If you are interested in who does what on a specific theme or topic at CEFE, please go to the WHO DOES WHAT tab and use the proposed tags. You will have direct access to the pages of the persons listed for a given tag.

If you are interested in what the different research Departments at cefe do and the focus of their respective teams, please go to the RESEARCH tab and navigate the Departments and their teams.

Thèmes de recherche
Ecologie comportementale spatiale (Movement Ecology): Mécanismes d'orientation; référentiels et processus de mémorisation; utilisation de l'espace et sélection de l'habitat.

Movement-based KDE Softwares (can also perform classical KDE if data are weakly correlated)
(Benhamou & Cornélis 2010, Benhamou 2011, Benhamou & Riotte-Lambert 2012, Benhamou 2018). Based on Gaussian (BRB/MKDE) or von Mises-Fisher (LonLat and ORI3D versions) kernels.

BRB/MKDE (Biased Random Bridges for Movement-based Kernel Density Estimation): Computation of Utilization Distribution (UD), and possibly Intensity Distribution (ID) and Recursion Distribution (RD), with optional boundary management, habitat selection analyses, and (for mountain environments) slope-based area corrections.
BRB/MKDE_LonLat (Biased Random Bridges for Movement-based Kernel Density Estimation without metric projection): Computation of UD, and possibly ID and RD, with optional boundary management and habitat selection analyses, for dealing with locations expressed in decimal degrees (longitude and latitude) over an extent that is too large to be properly represented on a planar map (very large home ranges, migration corridors). Example showing the migration corridor of great shearwater.
BRB/MKDE_ORI3D (Biased Random Bridges for Movement-based Kernel Density Estimation for orientations in 3D space): Computation of UD, and possibly ID and RD, of orientation in 3D space (either 3D heading, i.e. azimuth and elevation angle, or posture, i.e. elevation and bank angles) for fine-scale (i.e. locomotion) movement studies; Based on the same principles as BRB_MKDE_LonLat as azimuth and bank angle behave as longitudes, and elevation angle behaves as a latitude. Example
