When I was around 14, I saw one of the best movies. The movie was Gorillas in The Mist, starting Sigourney Weaver as Dian Fossey. It was one of the most impressive movies of my life. My step-mother at the time notice how must I liked the movie and game me her very well torn copy of Gorillas in the ...view middle of the document...
Gorillas tend to show the most stable grouping patterns. A group of adult gorillas will travel together for months and evens years at a time. A gorilla’s main diet consists of foliage and allows them to travel in permanent groups. Foliage, unlike fruit comes in large patches, which can support large groups of animals. (Csomos, 2008)
However, in west Africa, where fruits tend to makes up the majority of the gorilla's diet compared to those that live in east Africa. Groups of gorillas living in west Africa normally split into temporary feeding subgroups but are less common in east Africa, as animals range far apart searching for the relatively scarce ripe fruit. There are some reports of sleeping subgroups however, they are rare. This may occur in the process of permanent splitting of a multi-male groups into two single male groups. Groups usually can range from 5 to 10 individuals, but some groups can accumulate as many as 20 to 32 animals. (Csomos, 2008)
The habitat of the Western Lowland Gorilla is made up of primarily rainforests, swamp forest, thickets, forest edges, and clearings. Western Gorillas have been seen nesting in along the Savannah forest edge or in the Savannah itself. Although they visit the Savannah, it is not a permanent habitat for them. Western Gorillas inhabit areas that are typically lowland tropical forest at sea-level and up to 1,300 mm. (Beudels-Jamer, 2008)
This inhabitance seems to correlate with areas that contain large amounts of terrestrial herbaceous venation, areas that particularly contain ginger and palm. The average rain fall for this area is around 1,500 mm between August and November. The rain begins to diminish in December and continues until March. Western Gorillas tend to stay away from humans, avoiding human settlements, utilized roads, and plantations. Western Gorillas favor areas that are rich with edible herbs. (Beudels-Jamer, 2008)
Gorillas are mainly herbivorous, with the exception of insects like termites and ants. The availability of food affects the gorilla’s diet and foraging behavior. High quality herbs rich in proteins and minerals are patchily distributed outside swamp forest areas. Fruits are relatively available. When fruit is abundant the gorillas will make fruits their main ingredient of their diet. High quality herbs are eaten all year round, while low quality herbs are only eaten when fruit is unavailable. An adult male can eat up to 200 pounds of vegetation a day. Leaves and woody vegetation are consumed during the dry season, when fruits are not available. When fruits are available, the gorillas have longer day ranges and when the gorillas rely on leaves and woody vegetation they have shorter day ranges. (Beudels-Jamer, 2008)
Other Life Forms and Interrelations:
In this region of the world, the gorillas live among many rare species in the world. Some of these species included the common chimpanzee, the bonobo, the forest elephant, okapi, white rhino,...
