a Location of the study area in Montagne d’Ambre, in northern Madagascar showing the northern (1073 m asl) and southern site (848 m asl) for mouse lemur sampling (red and blue circles) and the study site for lacustrine sediment coring at 1250 m asl (star). All three sites were within 18 km of each other. The white triangle represents the mountaintop. The distribution area was drawn based on resources available in the public domain Microsoft Bing Virtual Earth. Individual coordinates can be found in Supplementary Table S2. b Assignment of 38 individuals to two genetic clusters (K = 2) using genotype likelihoods. Each individual is represented by a single horizontal bar and each color represents a distinct genetic cluster. Samples are sorted by sampling site. The animals sampled in the northern and southern site were assigned to two distinct genetic clusters with low levels of admixture between the two sites.
