Summary:
Cercopithecus monkeys are a species-rich radiation where interspecific mating leads to novel phenotypes due to pelage color and pattern diversity within the genus. The goals of this thesis were to (1) test a new method for studying color objectively in wild arboreal primates, and (2) apply a phenotypic hybrid index (PHI) to known individuals of a hybrid zone between C. ascanius and C. mitis in Gombe National Park, Tanzania through the use of digital photography. I scored seven pelage character states as 0 (C. mitis), 0.25 (mitis-like), 0.50 (intermediate), 0.75 (ascanius-like), or 1 (C. ascanius). Photos indicate most phenotypic hybrids express a white nose spot, but all other regions of pelage color and pattern are variable, and an assortment of hybrid phenotypes are seen at Gombe. Results indicate it is currently not possible to extend parameters for assessing color objectively with RGB values, but numerical non-RGB methods show promise.
