A Comparison of Body Size, Coat Condition and Endoparasite Diversity of Wild Barbary Macaques Exposed to Different Levels of Tourism

Abstract

Primate tourism is a rapidly growing industry with the potential to provide considerable conservation benefits. However, assessing the impact of tourists on the animals involved is vital to ensure that the conservation value of primate tourism is maximized. In this study, we compared body size, coat condition, and endoparasite diversity of wild, adult Barbary macaques exposed to different levels of tourism. Study animals belonged to three groups located in the Middle Atlas Mountains, Morocco: "green group" (GG) and "scarlet group" (SG) were exposed to negligible/no tourism, while the "tourist group" (TG) was exposed to very high levels of tourism. We used photogrammetry to quantify body size, scored coat condition from photographs, and quantified endoparasite species number from fecal samples. For both males and females, TG animals had deeper stomachs and wider hips than SG and GG animals. The coat condition of TG males was worse than that of SG and GG males, but no difference between groups was seen for females. Fecal samples from TG males contained a greater mean number of protozoan species than did samples from SG and GG males; for females a similar difference was found between TG and GG, but not between TG and SG. This study provides evidence that tourism has impacts on the body size, coat condition, and endoparasite diversity of Barbary macaques at this site. Further study is required to assess whether such effects are detrimental to the health of these animals.

Anthropogenic influences on the time budgets of urban vervet monkeys

“…Trends found followed expected patterns of energetic constraints (Borg et al, 2015;Mcfarland, Henzi, Barrett, & Wanigaratne, 2015). An unexpected finding was the seasonal effect of foraging.…”

Human speech reduces pygmy marmoset (Cebuella pygmaea) feeding and resting at a Peruvian tourist site, with louder volumes decreasing visibility

“…Negative impacts on visited species is one reason ecotourism projects may be unsustainable. These impacts may be apparent at the population level, such as population decline (McClung, Seddon, Massaro, & Setiawan, ; Watson, Bolton, & Monaghan, ), or at the individual level, such as behavioral (Meissner et al, ; Shutt et al, ), physiological (Behie, Pavelka, & Chapman, ; Zwijacz‐Kozica et al, ), and morphological (Borg et al, ; Maréchal, Semple, Majolo, & Maclarnon, ) changes.…”

Occurrence of gastrointestinal parasites in wild animals in State of Paraná, Brazil

“…Gastrointestinal parasites represent a major health problem and the symptoms resulting from these infections include: apathy, colic, diarrhea, malaise and weight loss. Studies are finding new 232 LEW K. SPRENGER et al informations about the ecology and biodiversity of endoparasites (Borg et al 2014). However, due to the large number of animal species, there is still a lack of information about the various animals of the Brazilian and international fauna, and their parasitic population (Santos et al 2008).…”
