Diameters of neighborhoods with different numbers of nearest neighbors. The figure displays the average diameters of the nearest neighborhoods of individuals with griseorufus-like mitochondrial haplotypes at Mangatsiaka and Tsimelahy. We calculated average diameters for neighborhoods including different numbers of nearest neighbors based on three datasets: Mtk: Mangatsiaka; Mtk_Riv: Mangatsiaka, all murinus-like individuals sampled more than 50 m from the nearest watercourse excluded; Tml: Tsimelahy. For each dataset, we calculated diameters based on all individuals (_all) and as an average over 100 randomly resampled datasets, where we reduced the number of murinus-like individuals to the number of griseorufus-like individuals (_res).
