Endoparasites of Western Lowland Gorillas (Gorilla gorilla gorilla) at Bai Hokou, Central African Republic

Endoparasites of western lowland gorillas (Gorilla gorilla gorilla) at Bai Hokou, Central African Republic.

A coprologic study of free-ranging western lowland gorillas (Gorilla gorilla gorilla) at Bai Hokou, Dzangha-Ndoki National Park, Central African Republic (2 degrees 51'34''N, 16 degrees 28'03''E) was conducted from October 1999 to November 2000. All 75 fecal samples examined were positive for endoparasites, and each contained at least two species. Parasites present included two genera of amoeba...

Behavioral responses of one western lowland gorilla (Gorilla gorilla gorilla) group at Bai Hokou, Central African Republic, to tourists, researchers and trackers.

Gorilla tourism, widely perceived as a lucrative industry, is propelled by strong market demand with programs in five countries and for three of four gorilla subspecies. Human presence may negatively affect wild gorillas, potentially lowering immunity and increasing the likelihood of acquiring human-borne disease. Yet, behavioral impacts of humans on wild gorilla behavior remain largely unexplo...

Effects of selected behavioral enrichment devices on behavior of Western Lowland Gorillas (Gorilla gorilla gorilla).

Environmental complexity plays an integral role in the activity and psychological well-being of primates. The experiment described in this article evaluates the effects of nonintrusive, inexpensive, and easily managed behavioral enrichment devices on the behavior of a group of captive Western lowland gorillas. Devices used included cardboard boxes containing food items, paper bags containing fo...

Western lowland gorillas (Gorilla gorilla gorilla) change their activity patterns in response to frugivory.

The most important environmental factor explaining interspecies variation in ecology and sociality of the great apes is likely to be variation in resource availability. Relatively little is known about the activity patterns of western lowland gorillas (Gorilla gorilla gorilla), which inhabit a dramatically different environment from the well-studied mountain gorillas (G. beringei beringei). Thi...
