When a gorilla becomes entangled in a snare set out for an antelope or other animal, the circulation to the appendage is often cut off. This can result in the loss of the limb, followed by gangrene, and even death. 4 Gorillas are also afflicted with parasites, the most common being intestinal parasites. Researchers have found evidence of nematodes, including hookworm. In addition to dealing with human diseases, gorillas compete with humans for land.
Humans are very aggressive competitors, while gorillas are much more passive.
When land is taken away, gorillas will search for additional food sources, which may include a farmer's neighboring crop. I found no reports on mutualisms involving the mountain gorilla. They are, therefore, primary consumers and are located in the middle of the food web. Humans are above the gorilla, as some native tribes may eat gorilla meat. Present censuses indicate that there are now approximately 620 mountain gorillas in the wild.
