Isotopic_Niche_Overlap
YannPlanque / Isotopic_Niche_Overlap
Identification of isotopic niches by considering both intra- and interindividual variability (a novel hierarchical Basyesian model). Measure the isotopic niche overlap. The method is ajusted to isotopic data with intra-individual variability (e.g. measures on whiskers, feathers, tooth).

Diet_Cluster_and_Overlap
YannPlanque / Diet_Cluster_and_Overlap
Quantify the diet composition in % by mass of prey found by analysing the content of samples (e.g. scats, stomachs), identify diet clusters, and measure interspecific overlap.

Foraging_Areas_with_Dive_Data
YannPlanque / Foraging_Areas_with_Dive_Data
Seal foraging areas identified by analysing the dive data obtained from telemetry tracking. Select the likely foraging dives using a vertical approach (Planque et al. 2020), and spatialise them with Kernel densities.
