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 (BRB/MKDE_DD, BRB/MKDE_ORI3D) 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_DD (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 a too large extent to be projected (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_DD as azimuth and bank angle behave as longitudes, and elevation angle behaves as a latitude.
