Figure 4: Bayesian analysis of STR multilocus genotypes as computed with Structure.

Each individual was represented as a vertical bar partitioned in K segments, whose length is proportional to the estimated membership to the K clusters. (A) Lutrogale perspicillata (Singapore excluded), with K = 3. Middle East: Iraq; South Asia: Pakistan, India, Nepal and Bangladesh; Southeast Asia: from Thailand to Malaysian Borneo. (B) Singapore smooth coated otters compared to either L. perspicillata or A. cinereus parental control, with K = 2 (see text for details). Legend: *individual from southern Bangladesh (Khulna Division): next column to the right refers to the second otter from northern Bangladesh (see Supplementary Table S1); **dead otter found near Kranji Dam, Singapore.
