Gorilla beringei beringei, more commonly known as the Mountain Gorilla, is one of the most sexually dimorphic species of primates in existence. Sexual dimorphism is a phenotypic difference between males and females of the same species. The prototypical example is for differences in reproductive organs, but sexual dimorphism can affect many different characteristics. In mallard ducks for example, the male’s feathers are colored bright green, on its head in order to help attract the brown headed females. Peacock males, for example, have an illustrious plumage made up of many different colors whilst the female does not. In mountain gorillas, sexual dimorphism has caused a drastic difference in body size between the sexes. The male mountain gorilla, …show more content…
Unfortunately, the mountain gorilla is also known as one of four gorilla subspecies classified as critically endangered, with as few as 880 remaining in the wild today (Caulliad, 2014). One of the most prevalent threats to the mountain Gorilla population in today’s age is habitat loss. The mountain gorilla is found in two separate locations; the Virunga range of extinct volcanic mountains on the borders of the Democratic Republic of Congo (DRC), Rwanda and Uganda. While there are many national parks established to protect the mountain gorilla from losing their habitat such as the Bwindi Impenetrable National Park in Uganda, this area of gorilla sanctuary has been steadily decreasing since the 20th century. In 2004 in fact, more than 1,500 hectares of mountain gorilla habitat was illegally cleared by settlers in the Virunga National Park in the DRC (Caillaud, 2014). This continued habitat loss is detrimental for the survival of the mountain gorilla, which can eat up to 40 pounds of plant life per day. Severely limiting the amount of natural resources available to these gorillas increases the competition for food and drastically decreases the ability to sustain a large
The life history of the Cross River Gorilla is considerably long, ranging from gestation period to death (Save Our Species), (Imong, I., & Robbins, M.). The normal female gorilla will not
There are many wild animals in the world are in danger. The mountain gorillas (Gorilla beringei beringei) are one of the most threatened species in the world that inherited from monkeys (Macaca Fascicularis) and apes (Hominoidea), which was found in Africa and Arabia about 34-24 millions years ago. Mountain gorillas are Animalia, which phylum is Chordata and class of Mammalia. The mountain gorilla is a subspecies of eastern gorilla, which live in two regions in Africa. There are three countries where mountain gorillas live. They are Uganda, Rwanda and Democratic Republic of Congo. According to National geographic, there are about 700 mountain gorillas remaining in the earth and half of them live in a Virunga mountains in central Africa. In average, they live about 35 years; the standing height of a mountain gorilla is between 4-6 feet. They’re weight usually between 300-485 pounds and they are bit larger than other type of gorillas. Mountain gorilla usually live in a group and head of their group is called ‘silverback’ that is an adult male who grow a patch of silver hair on their back and hips. However, when dominant silverback die, the whole group face hard time to regroup themselves. Female gorilla usually becomes sexually mature before male gorilla. At the age of 7-8 female gorillas become sexually active, however they started to breed few years later. On the other hand, male gorilla starts
Von Beringe discovered the primate on the summits of the Virunga Volcanoes (Berggorilla and Direkthilfe, 2000). The officer described the mountain gorilla as to be a large manlike ape, that was tall in stature (about 1 1/2 meters tall), and weighed over 200 pounds (Schaller, 2010). The mountain gorilla physical characteristics from other subspecies of primate differs by: lengthy hair, jaw, and teeth, as well as shorter arms (http://wwf-congobasin.org/, 2010). The mountain gorilla is one of the most wooly of primates, it has a long thick coat of fur that is necessary for the high cold altitudes. (Hilyard, 2001). Also, when male
Gentle, peaceful & shy are the words that describe gorillas. Gorillas in the mountains & eastern lowland areas are totally vegetarian & eat leaves, fruits, & stems like bamboo. On the other hand, gorillas in the Western lowlands eat small invertebrates & insects apart from plants. It’s anticipated that approximately 80% of gorilla population’s extinct, because of the destruction of their habitat, humans hunting them down & diseases as a result of Ebola
Costa Rican Howler Monkeys are one of the most biggest most pickiest most laziest monkeys I have heard of. Did you know there are a lot of different species here are a few Black Howler, Mantled Howler, Red Howler and the Brown Howler. The size of a howler monkey is relative to a 6ft. Man and there tale is 23 to 36 inches long! They spend time grooming there long bodies and long tales and they always have time to take their naps and eat food. There favorite food is fruit but they also eat nuts and seeds. Do you want to know one of there favorite fruit pears. But they are starting to lose their habitats and because of that they are losing they food also. But there are some animals that like to eat howler monkeys jaguar,snakes and birds. Do you
There are three different types of gorillas in the groups. There is the silverback male. Silverbacks are the adult males. They get silver hair on their back as part of their growing process, just like when boys grow up and get mustaches
Western and Eastern gorillas are more genetically distant from one another than are chimpanzees and bonobos. There are few striking physical differences between the subspecies of gorilla, although differences in dentition and skulls reveal distinguishing morphological characteristics of each subspecies. Mountain gorillas have significantly longer hair than their conspecifics, while western gorillas have brown hair. Eastern gorillas have longer faces and broader chests than western gorillas (Rowe 1996; Nowak 1999). Gorillas have dark brown to black fur and black skin. Dominant adult males who control the group, is called silverbacks because have a prominent sagittal crest and striking silver coloration from their shoulders to rump.
Western lowland gorillas are sexually dimorphic with the male gorillas being about 2 times as large as female gorillas (San Diego Zoo Global 2006). Male gorillas are 400–500 pounds, on average, and female gorillas are only 159–216 pounds (Cawthon Lang 2005). The males also are taller than the females when standing bipedally, at around 1700 millimeters (~5 '5") on average, 200 millimeters more than their female counterparts (Cawthon Lang 2005). Gorillas’ arms are longer than their legs, which helps with their knuckle-walking (Saint Louis Zoo n.d.). The habitual mode of locomotion for gorillas is primarily knuckle-walking (Cawthon Lang 2005), but they can walk bipedally for a short amount of time (Saint Louis Zoo n.d.). Western lowland gorillas differ from other gorilla subspecies in that they have brownish (rather than black) fur (World Wildlife
I have finally came to a very difficult decision of choosing the new mascot for our school. I have chose the Lowland Gorillas. In the two following paragraphs I will explain my decision of choosing the Gorillas and also why I think they are the best option. We would need a mascot that is tough and dangerous and will crush the enemy. I feel like the gorilla is our best option for that.
The weather of my first visit was 48/41᷾⁰ F, cloudy and there was a lot of wind and humidity. I came around 11:40 am and left at 1:21 pm. My second visit the weather was 37/36⁰ F, it drizzle, was mostly cloudy and there was a lot of humidity but not a lot windy. All of my observations include a 20 minutes observation of each primate as it cohabitated with other primates and with other members of its own species. My findings will support the research of Western Lowland Gorilla and Cotton-Top Tamarin through firsthand
Primate conservation has long been a topic of debate, reliant most heavily on the struggle to provide the necessary resources to combat the declining rate of population growth among various species. Orangutans in particular, both Sumatran and Bornean, have experienced a rapid drop in their free-living populations. With an estimate of only 27,000 left in the wild, questions have been raised over what selective pressures are impacting the steady decline of these animals existence. While hunting and poaching have been identified as contributing factors, habitat loss primarily takes center stage in their demise. Conservation efforts have been made and continue to be somewhat successful, however, challenges and set backs continue to threaten
The story begins on a snowy Christmas day about three years ago. My family and I were at my Gma’s house opening presents by the toasty fire. At this point in time it was safe to say that I had a small obsession with large stuffed animals. I had asked for a giant stuffed gorilla from my Aunt Katie to start my collection. Although she tried to disguise it, I knew instantly what it was because of the large box she put it in. I was overjoyed when I opened it and I gave her and my Uncle Mike hugs. I quickly decided that the best name would be “gorilly”, and at the time I thought that I was extremely creative. I oogled at the gorilla for the next couple hours that we were at my Gma’s, and when we left to go to my other Grandma’s house I wanted to make sure I had this giant gorilla on my lap. I thought that by doing this the gorilla would be more “safe” and I didn’t have the slightest idea of how this would ever affect me.
At about age 10, mountain gorillas reach sexual maturity and are able to have their own offspring. Females have one infant at a time and have a pregnancy period of 9 months. There are only 3 days each month that female mountain gorillas can conceive. After a female gorilla`s first ovulatory cycle, they have to wait at least 2 years before they
Female gorillas leave the group when they are mature enough to start breeding. Females often do not get attached to one another, for competition of grooming and staying
The Virunga National Park is one of the most biologically diverse areas on the planet and home to a short list of endangered mountain gorillas. Currently, there are 880 mountain gorillas located in the forests shared between the Democratic Republic of Congo, Rwanda, and Uganda. Virunga was the first national park founded by King Albert I of Belgium in Africa. The park was founded in order to protect the mountain gorillas, but unfortunately poaching had caused them to go extinct. The Democratic Republic of the Congo is extremely rich in natural resources, but is politically unstable, has a lack of infrastructure, and deep corruption. The Congo had faced serious threats since the Civil War and wasn’t declared independent until 1960. In 1994, factions of african rebel groups are trying to gain control of natural resources to sell to foreign corporations. Since parts of Virunga lies on the eastern Congo, the park also lies within the natural resources that European private corporations are highly interested. It wasn’t until 2010 when oil was discovered in the eastern Congo (Virunga National Park). The Virunga National Park is known for its
