They live in primary and secondary lowland tropical forests that have elevations that extend from sea level up to 1, meters. The average amount of rainfall in the areas where western lowland gorillas typically reside is about 1, millimetres a year with the greatest rainfall between the months of August and November.
Western lowland gorillas are not typically observed in areas that are close to human settlements and villages. They have been known to avoid areas with roads and farms that show signs of human activity.
These gorillas favor areas where edible plants are more copious. Swamp forests are now considered important feeding areas and habitats for the western lowland gorilla.
These areas support the gorillas in both the wet and the dry season of the forest. The forests of the Republic of Congo serve as protection to the gorillas with the isolation of the large swampy forest areas.
As primarily herbivores, the main diet of western lowland gorilla groups is roots, shoots, fruit, wild celery, tree bark and pulp which is provided for in the thick forests of central and west Africa.
While in the dry season, there is a decrease in the consumption of fleshy fruits, but they still continue to eat other kinds of fruits.
The diversity of fruits consumed was higher in the poor fruit year,when favored fruit species, failed to produce large crops.
The common food item within fibers are the herbaceous stems. They never completely strip vegetation from a single area since the rapid regrowth of the vegetation allows them to stay within a reasonably confined home range for extended periods of time.
However, when ripe fruit is available, they tend to eat more fruit as opposed to foliage. When ripe fruit is in scarce supply, they eat leaves, herbs and bark.
During the rainy months of July and August, fruit is ripe; however, in the dry seasons, ripe fruit is scarce. Gorillas choose fruit that is high in sugar for energy, as well as fibre.
The presence of western lowland gorillas has allowed humans to further the study of how gorillas compare with humans in regards to human diseases, behavior, linguistic and psychological aspects of their lives.
They are hunted illegally for their skins and meat in Africa and captured to be sold to zoos. While defended as being economically profitable for restaurants and local people, it is a large contributor to the endangered status of the western lowland gorilla.
They are also seen as a crop pest in western Africa because they raid native plantations and therefore destroy what would have otherwise been valuable crops.
In tropical forests, gorillas are hunted to provide meat for the bushmeat trade. Logging also destroys gorilla habitats. Although logging diminishes gorilla habitats, it may also provide for increased herbaceous vegetation as a result of gaps in the tree cover.
Destruction of gorilla habitat may harm the overall forest ecosystem. Western lowland gorillas are seed dispersers, which mean they carry seeds from one place to another, and this trait is beneficial to many of the animals in the forest.
Therefore, if there are no western lowland gorillas to disperse the needed seeds to other animals, not only will the gorillas become extinct but so will many other animals, which could over time destroy an entire ecosystem.
The western lowland gorilla population in the wild is faced by a number of factors that threaten its extinction. Such factors include deforestation, farming, grazing and the expanding human settlements that cause forest loss.
There is a correlation between human intervention in the wild with the destruction of habitats and increase in bushmeat hunting. Generally, female gorillas mature at 10—12 years of age or earlier at 7—8 years and their male counterparts mature more slowly, rarely strong and dominant enough to reproduce before 15—20 years of age.
However, these non-reproductive gorillas may prove to be a valuable resource since the use of assisted reproductive techniques aid in the maintaining of genetic diversity in the limited populations in zoos.
In the s, a census of the gorilla populations in equatorial Africa was thought to be , Researchers later adjusted the figure to less than half because of poaching and diseases.
However, gorillas remain vulnerable to Ebola , deforestation and poaching. This population decreased from individuals to 38 individuals two years after the outbreak and to 40 individuals six years after the outbreak.
The population is still slowly recovering, even today, it is hoped towards a population that has the same demographic structure of an unaffected population, because of new births and breeding groups.
Because of these outbreaks, the International Union for Conservation of Nature IUCN updated the status of western lowland gorillas from "endangered" to "critically endangered".
In the northeastern part of the Republic of the Congo, even though poaching is illegal, western lowland gorillas are still being hunted for their bushmeat and the young for pets; five percent of the species is killed each year because of this.
Deforestation of this area allows for the trade of bushmeat and even more poaching. Deforestation and logging allowed for the creation of roads which allowed hunters to hunt deeper into the forests, increasing the amount of poaching and bushmeat trade in the area.
The Republic of the Congo has put in place a conservation effort to conserve different species such as chimpanzees, forest elephants and western gorillas from poaching and deforestation.
This conservation effort would allow these species to benefit from vegetation and ecologically important resources. The western lowland gorilla is considered to be critically endangered by the IUCN.
The western lowland gorillas, like many gorillas, are essential to the composition of the rainforest due to their seed distribution.
The WCS is also working in Congo and surrounding countries to limit the bush meat trade by enforcing laws and hunting restrictions and also helping the local people find new sources of protein.
Zoos worldwide have a population of western lowland gorillas, and the Cincinnati Zoo leads the United States in western lowland gorilla births. Stress has been known to cause both physiological and behavioral chronic issues for captive species including, but not limited to, altered reproductive cycling and behavior, reduced immune responses, disrupted hormone and growth levels, reduced body weight, heightened abnormal activities and aggression and decreased exploratory behavior with increased hiding behaviors.
Stereotypic behaviors are abnormal or compulsive behaviors. In captive gorillas, such common aberrant behaviors include eating disorders—such as regurgitation, reingestion and coprophagy —self injurious or conspecific aggression, pacing, rocking, sucking of fingers or lip smacking, and overgrooming  Negative vigilance of visitor behaviors have been identified as starting, posturing and charging at visitors.
A particular abnormal behavior is hair-plucking, which occurs across many species of mammals and birds.
Individual gorillas, particularly those of a more solitary nature, are more likely to self-pluck using their fingers and pick up this behavior if they were exposed to a group member that plucked their hair as a youngster and not yet mature gorilla.
Recent research on captive gorilla welfare emphasizes a need to shift to individual assessments instead of a one size fits all group approach to understanding how welfare increases or decreases based on a variety of factors.
The gorilla became the next-to-last great ape genus to have its genome sequenced. This was done in Furthermore, in , a study was conducted in order to better understand the genetic variation in gorillas by using reduced representation sequencing.
This study consisted of a sample of 12 western lowland gorillas and two eastern lowland gorillas all in captivity.
The study found that western lowland gorillas are more likely to be heterozygous than homozygous. Therefore, because of variation in these gorillas, it has been concluded that they display a moderate substructure within the western lowland population in general.
Finally, the study sought out to analyze the allele frequency spectrum AFS in western lowland gorillas. The reason why is that AFS knowledge can help give information regarding demographics and evolutionary processes.
The AFS has determined that western lowland gorillas display a deficit of rare alleles. This clustering allows us to pinpoint the probable geographic origins of two of the human virus clades.
In the southern part of Cameroon, the populations of western lowland gorillas have had examinations of their feces. Out of 2, gorilla samples, 70 reacted with at least one HIV-1 antigen.
These samples came from four field sites, all located in southern Cameroon. The origin of AIDS has been linked to a virus known to infect more than 40 species of nonhuman primates in Africa.
HIV-1, is composed of four phylogenetic lineages, which at some point in time have independently gone through cross-species transmission of the SIV simian immune-deficiency virus.
The simian immunodeficiency virus infected various African primates such as apes, gorillas and chimpanzees. Gorilla gorilla Gorilla beringei.
Gorillas are ground-dwelling, predominantly herbivorous apes that inhabit the forests of central Sub-Saharan Africa. The genus Gorilla is divided into two species: They are the largest living primates.
Gorillas' natural habitats cover tropical or subtropical forests in Sub-Saharan Africa. Although their range covers a small percentage of Sub-Saharan Africa, gorillas cover a wide range of elevations.
Lowland gorillas live in dense forests and lowland swamps and marshes as low as sea level , with western lowland gorillas living in Central West African countries and eastern lowland gorillas living in the Democratic Republic of the Congo near its border with Rwanda.
The word "gorilla" comes from the history of Hanno the Navigator , c. The American physician and missionary Thomas Staughton Savage and naturalist Jeffries Wyman first described the western gorilla they called it Troglodytes gorilla in from specimens obtained in Liberia.
The closest relatives of gorillas are the other two Homininae genera, chimpanzees and humans, all of them having diverged from a common ancestor about 7 million years ago.
More recently, a third subspecies has been claimed to exist in one of the species. The separate species and subspecies developed from a single type of gorilla during the Ice Age , when their forest habitats shrank and became isolated from each other.
Primatologists continue to explore the relationships between various gorilla populations. The proposed third subspecies of Gorilla beringei , which has not yet received a trinomen , is the Bwindi population of the mountain gorilla, sometimes called the Bwindi gorilla.
Some variations that distinguish the classifications of gorilla include varying density, size, hair colour, length, culture, and facial widths.
Adult males are 1. Female gorillas are shorter at 1. The tallest gorilla recorded was a 1. Adult males also have a prominent sagittal crest.
The eastern gorilla is more darkly coloured than the western gorilla, with the mountain gorilla being the darkest of all. The mountain gorilla also has the thickest hair.
The western lowland gorilla can be brown or grayish with a reddish forehead. In addition, gorillas that live in lowland forests are more slender and agile than the more bulky mountain gorillas.
The eastern gorilla also has a longer face and broader chest than the western gorilla. Studies have shown gorilla blood is not reactive to anti-A and anti-B monoclonal antibodies , which would, in humans, indicate type O blood.
Due to novel sequences, though, it is different enough to not conform with the human ABO blood group system , into which the other great apes fit.
Gorillas have a patchy distribution. The range of the two species is separated by the Congo River and its tributaries.
The western gorilla lives in west central Africa, while the eastern gorilla lives in east central Africa. Between the species, and even within the species, gorillas live in a variety of habitats and elevations.
Gorilla habitat ranges from montane forests to swamps. Gorillas construct nests for daytime and night use.
Gorillas, unlike chimpanzees or orangutans, tend to sleep in nests on the ground. The young nest with their mothers, but construct nests after three years of age, initially close to those of their mothers.
A gorilla's day is synchronized, divided between rest periods and travel or feeding periods. Diets differ between and within species. Mountain gorillas mostly eat foliage, such as leaves, stems, pith, and shoots, while fruit makes up a very small part of their diets.
Eastern lowland gorillas have more diverse diets, which vary seasonally. Since fruit is less available, lowland gorillas must travel farther each day, and their home ranges vary from 2.
Eastern lowland gorillas will also eat insects, preferably ants. Termites and ants are also eaten. Gorillas rarely drink water "because they consume succulent vegetation that is comprised of almost half water as well as morning dew",  although both mountain and lowland gorillas have been observed drinking.
Gorillas live in groups called troops. Troops tend to be made of one adult male or silverback, multiple adult females and their offspring.
Silverbacks also have large canine teeth that also come with maturity. Both males and females tend to emigrate from their natal groups. For mountain gorillas, females disperse from their natal troops more than males.
Mature males also tend to leave their groups and establish their own troops by attracting emigrating females. However, male mountain gorillas sometimes stay in their natal troops and become subordinate to the silverback.
If the silverback dies, these males may be able to become dominant or mate with the females. This behaviour has not been observed in eastern lowland gorillas.
In a single male group, when the silverback dies, the females and their offspring disperse and find a new troop.
Joining a new group is likely to be a tactic against this. This likely serves as protection from leopards. The silverback is the center of the troop's attention, making all the decisions, mediating conflicts, determining the movements of the group, leading the others to feeding sites, and taking responsibility for the safety and well-being of the troop.
Younger males subordinate to the silverback, known as blackbacks, may serve as backup protection. Blackbacks are aged between 8 and 12 years  and lack the silver back hair.
The bond that a silverback has with his females forms the core of gorilla social life. Bonds between them are maintained by grooming and staying close together.
Relationships between females may vary. Maternally related females in a troop tend to be friendly towards each other and associate closely.
Otherwise, females have few friendly encounters and commonly act aggressively towards each other.
Females may fight for social access to males and a male may intervene. Males in all-male groups, though, tend to have friendly interactions and socialise through play, grooming, and staying together,  and occasionally they even engage in homosexual interactions.
One possible predator of gorillas is the leopard. Gorilla remains have been found in leopard scat, but this may be the result of scavenging.
Females mature at 10—12 years earlier in captivity , and males at 11—13 years. The gestation period lasts 8. Female mountain gorillas first give birth at 10 years of age and have four-year interbirth intervals.
