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.
