Fecal samples were obtained from guenons in Gombe National Park utilizing noninvasive, opportunistic sampling techniques. Samples were then examined for the presence of gastrointestinal parasites using chlorazol black stain, Lugol’s iodine staining, as well as concentration via fecal flotation with Sheather’s sugar solution. Results were analyzed using SPSS (IBM corp), and compared to other forested regions in Africa to determine whether hybridization influences parasite prevalence of these guenons living in Gombe; and if these guenons differ from similar guenons in other regions of Africa. The null hypothesis was unable to be rejected in all cases; hybridization could not be stated as a contributing factor for differences found in parasitic prevalence rates. Furthermore, no statistical difference was found between Gombe’s guenons, and those living in other regions of Africa in most cases. The author suspects that the abundance of parasitic generalists discovered, small sample size, and opportunistic sampling protocol contribute to these finding. / Includes bibliography. / Thesis (M.A.)--Florida Atlantic University, 2017. / FAU Electronic Theses and Dissertations Collection
