This low level of paternally-transmitted genetic diversity among the Ugalla males may be the result of a small or highly related, recent founder population (i.e., genetic drift), exacerbated by the male philopatric structure of chimpanzee communities and by male reproductive skew.Īncrenaz M, Gimenez O, Ambu L, Ancrenaz K, Andau P, Goossens B, Payne J, Sawang A, Tuuga A, Lackman-Ancrenaz I (2005) Aerial surveys give new estimates for Orangutans in Sabah, Malaysia. ![]() In addition, the most prevalent haplotype, found in 52 of the males, is distributed across the entire surveyed area of 624 km 2. While autosomal genetic diversity is within the range of other eastern populations, at 0.27 the gene diversity of the Y-chromosome haplotypes present among 61 Ugalla males is extremely low as compared to other eastern chimpanzee populations. We also analyzed 13 Y-chromosome loci in the Ugalla males. We collected 237 fecal samples from a 624 km 2 area of the Ugalla region, analyzed the DNA at 12 autosomal loci and identified 113 individuals (69 males and 44 females). In this study, we estimate the genetic diversity of eastern chimpanzees in the Ugalla region of western Tanzania, which represents the easternmost distribution of the subspecies Pan troglodytes schweinfurthii. One of the three categories of biodiversity for conservation priority recommended by the International Union for the Conservation of Nature is genetic diversity.
