Video Analysis: Aggression In Sea Lions

The Gorilla beringei beringei or mountain gorilla, was first discovered on October 17th 1902, by a German officer named Captain Robert von Beringe (Berggorilla and Direkthilfe, 2002). Mountain gorillas play a large role in it’s particular ecosystem through consumption the gorillas control and maintain vegetation that is vital for a healthy environment not only for the primate but also other species that live in the environment as well. Since the discovery of the mountain gorilla much fascination has been drawn toward the species. However, the gentle creature’s population has had a sharp decline from Rwanda’s belief in sumu, poaching, human disease, and unregulated tourism. In efforts to revive the species population from extinction, persistent activism through worldly foundations are helping protect the mountain gorilla species.

Sixteen baby monkeys were used, four in four different condition. One where there was a cage containing a wire mother producing milk and a towelling mother with no milk. Second, with a cage containing a wire mother producing no milk and the towel mother procuring milk. Third, with a cage containing a wire mother producing milk and fourth, with a cage containing a towelling mother producing milk. He then recorded the amount of time spent with

“In their natural homes in the wild, chimpanzees humans’ closest living genetic relatives”, who are more like us than they’re like gorillas are never separated from their families and troops . “Profoundly social beings, they spend every day together exploring, crafting and using tools to solve problems, foraging, playing, grooming each other, and making soft nests for sleeping each night” . They care deeply for their families and forge lifelong friendships . Chimpanzee mothers are loving and protective, nursing their infants and sharing their nests with them for four to six years . They have excellent memories and share cultural traditions with their children and peers . They empathize with one another and console their friends when they’re upset . They help others, even at a personal cost to themselves . When one of another

After about 10 minutes, he is abruptly bothered by the youngster who is running on his knuckles towards the male and runs back up the hill as if he is taunting him. The youngster does it about 3 mores times within the next 7 minutes and perches upon the hill in the same position as the silverback, except he is bended at the knees in squat position. In my second visit, I return to the gorilla exhibit for about 10 minutes to see a female unknown if related to the previous observation in submission. She is found crouched to the floor with her elbows on the ground and hands extended out and her butt perched up. Her hind legs are also bent and position to help support her butt. Three minutes upon observation, a silverback male comes running on his knuckles from another part of the exhibit and mounts the female. He positions himself on his knuckles to provide him support and continues with the sexual intercourse, in which I conclude my observations.

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

Within this essay, we will study more in depth the behavioral as well as physical traits of two primates at a zoo from their interaction with their peers to their place in the group. This observation would enable us to further understand the possible existing correlation between humans and primates. First, I studied a female chimpanzee with her baby, and then, a dominant male gorilla, in San Francisco Zoo at about noon, on May 23, 2015, for an hour each. Even though they share some similarities such as having a large brain, living for a long time, and being bored in their enclosure, they are still different; when gorillas are the largest, chimpanzees are the smartest. In fact, chimps use tools to catch food, they would not be able to reach

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

“Pair Living Primates have several unique characteristics that set them apart from other nonhuman primates. Monogamous Primates are two primates of different sexes that mate exclusively with one and other. The unique qualities of these animals are a result of the ecological constraints that these primates face. Because of the exclusive and solitary relationship that is monogamy there is a lack of specialized defensive roles by the adult male, which is also extensively involved in paternal care. Monogamous primates are highly territorial and very closely associated, Morphologically, there is a lack of sexual dimorphism amongst pair living primates, this is due to the exclusively and predictable genetic outcome of these animals mating with only

(Dunbar, 1983) Among mountain gorillas, half of all the groups are one male. However, females leave from one group to another. “Polygynous females might be compensated for loss of exclusive paternal care by mating with a genetically superior male, thereby increasing the likelihood of their progeny’s survival and ability to produce offspring (Alatalo and Lundberg 1986).” (Hoglund, J. 1995) The competition for these mating opportunities is driven by the female’s choice. When this occurs, the males lose females to another one male group and it exploits what males mating opportunities.

The first stage of the experiment is called modeling. In this stage the children were individually shown into a room where they would sit in one corner and pay with potato prints and pictures and the adult sat in the other corner with a mallet and the Bobo doll. In the first group, 24 children would watch a male or female adult abuse the doll both physically (kicked, punched, threw, and hit with different objects) and verbally (made aggressive and non-aggressive statements). In the second group, 24 children were exposed to adult who played quietly in the corner with the toys but avoiding the Bobo doll. The third group, 24 children were not exposed to neither an aggressive or non-aggressive adult. After 10 minutes went by, the adult in both groups left the

Harry Harlow’s thorough research on the connection between maternal comfort and rhesus monkeys provides information and knowledge to the reader as an insight into our social and emotional development. In this article, Harlow uses experimental observation of mental and emotional associations of the affectionate ties between the child and the mother. As Harlow says, this is “an instinct incapable of analysis”.

I decided to look at the sexual behavior of bonobos because they are known for their frequent sexual behavior. Though they are not one of the types of great apes mentioned in the book, a bonobo is nonetheless a great ape that belongs in the same genus as the common chimpanzee. Furuichi et al. observed bonobos in their naturalistic habitat in Wamba, Democratic Republic

Addressing the various mating systems of primates and its relation to sexual size dimorphism and behavior contributes to understanding evolutionary processes and patterns. The different methods of mating are significant to study because they demonstrate the outcomes of natural selection on mate choice. These varying mating methods also aide in understanding the origin of

Beginning with the most intelligent of the bunch, the (western lowland) gorillas I observed were quite inactive. This is certainly so because they are known to only be hunted by man leaving no competition outside of their own species. This fact makes it apparent why these kings of the jungle sit around so often. In the wild and even in zoos it may be difficult for a male to find mates because groups of gorillas are POLYGYNOUS. So usually one male is the father of all of the offspring. Being this way, male gorillas must display DOMINANCE over others and even stand their ground against an incoming male that may threaten the family. Going back to how they sit all day, gorillas are able to do this because they don’t even have to move to replenish energy for the reason that they are grass and leaf eaters (vegetarians). Not having to move very much makes gorillas capable of having a low-quality diet.
