Introduction I visited the Sacramento Zoo during the afternoon of April 21, 2017. The weather was wonderful, sunny, warm, and there was a slight breeze. It got a bit more breezy the longer I was there. Visiting the zoo to observe primates allowed me to become a little more aware of how primatologists study primates. Even though I’ve been to many different zoos several different times, I never realized how many primates were associated with the zoos, as well as the variety of primates in the zoos. The Sacramento Zoo has eight different primates, all in different classifications, superfamilies, or subfamilies. While observing the Chimpanzees, White-Handed Gibbon, Mongoose Lemur, White-Faced Saki, and the Wolf’s Guenon I could see the differences …show more content…
They have wide chests and their arms are longer than their legs. Chimpanzees’ hands have four long fingers plus an opposable thumb. Their feet have five toes which includes an opposable big toe. Chimpanzees’ can grasp things with both their hands and their feet. Male chimpanzees are larger than female chimpanzees and are slightly sexually dimorphic. Chimpanzees are quadrupeds that typically walk using the soles of feet and the knuckles of their hands. They sometimes walk upright only when they need to use their arms to carry things but this is a rare occurrence. Chimps are also good at brachiating and climbing trees which is where they spend most of their time even when they sleep. Their dental formula is 2.1.2.3. Chimpanzees’ have y5/x4 molars, making them frugivores, and a diastema to fit their upper canines. Their diet includes fruit, leaves, flowers, seeds, smaller mammals, birds, insects, and grubs. When chimps aren’t resting, they can be very active. I enjoyed watching the Chimpanzees’ swing on the ropes and climb up and down the trees. Chimpanzees are …show more content…
They have small heads and body’s with a long lumbar region and narrow chest. Saki’s are arboreal quadrupeds with their arms and legs equal in length. They have a long olecranon process to be able to lock their joints so that their limbs can hold equal weight. White-Faced Sakis have long prehensile tails and long phalanges on their hands and feet for better travel and balance in the trees. A Saki’s dental formula is 2.1.3.3 with triangular molars meaning they are insectivores. They are also known as "flying monkeys" because they are able to leap 30 feet between tree branches. I already knew they could leap so I was hoping to see that when I observed it, but it was resting when I was there. They are sexually dimorphic due to color. White-Faced Sakis are vulnerable to being
Dr. Goodall is a well-known British primatologist who has discovered a substantial amount about primates in her many years of research. She has written numerous books, including one that we will be going into depth about called, “Through a Window.” Her book contains personal experiences, research findings, and even pictures to help the readers visualize her scientific breaking moments from her thirty years with the chimpanzees of Gombe. She states that there is are minor differences, and several similarities between humans and the chimpanzees. We will discuss these differences and similarities through their social behavior, intellectual ability, and emotions. To conclude, examine Goodall’s research to adopt what her findings can tell us about our early ancestors, and whether or not her study coincided to the steps of scientific methodology.
This paper reviews and analyzes three main issues with the first one being leadership. Other sub-issues involve lack of vision, coercive leadership style, using taxpayer’s money for personal benefit and irresponsible top management. The organizational structure, mixed communication, and no clear indication to who to report to is the second. The third being communication, this paper tackles lack of the ability to speak about the actual problems in fear of being ostracized; if you’re not with us; you’re against us. We suggest a solution based on our SWOT analysis, star bursting, brainstorm, mind map, and rational decision making tool. With the use of these five tools we hope to help solve the problem at hand by making the city zoo a more engaging and dynamic experience for both employees and the public.
There are contrasts in tool kits used by different groups of chimpanzees, which seem to be a result of the environment in which they live as well as information that is shared by the group. For example, in 1973 it was reported that chimpanzees in Gombe did not use hammer stones, but those of Cape Palmas did. We will explore the tool use of Chimpanzees from the wild, including Gombe, Tai National Forest, and the Congo Basin---and contrast those with Chimpanzees in captivity in locations of Zoo’s both in the United States and abroad.
With a 99.6% genetic similarity to Chimpanzees , the physical appearance of Bonobos is very similar to them. The length of the legs, in proportion to the arms, Bonobo’s dark faces, pink lips, and more slender stature are just some of the cosmetic differences between them and Chimpanzees. Bonobos are notorious for their bipedalism, walking upright. Granted Chimpanzees can preform bipedalism when needed, but do not match the ease and grace of the Bonobo. With their habitat staying more constant, sense the forma...
...ey have specially adapted hind legs to help them fly through the air at such great distances. The trees that they land on are super spiky and nobody really knows how they can land on the branches directly without hurting their feet, which is clearly an adaptive trait seeing as no other primate can do what they do. The Sifaka is not designed to walk on all fours, ground locomotion wastes energy, tires them out, and makes them susceptible to snakes and other predators. Which is why they choose to hangout in the trees, away from predators-- so they can work smarter not harder. This to me shows that they are using their brains, just as humans do to avoid expending more energy than necessary to get by.
All primates have essentially the same kinds of specialized mammalian teeth adapted to eating a wide variety of foods. Beginning at the front, each quadrant of the mouth has 2 incisors, 1 canine, and varying numbers of premolars and molars. The incisors are used like scissors for nipping off pieces of food. The pointed canines are for piercing and tearing. The premolars and molars, with their cusps, are used to grind and smash food. In platyrrhine species, there are 3 premolars and 2 or 3 molars. This results in a dental formula of 2.1.3.2 or 2.1.3.3. In contrast, all of the catarrhines have 2 premolars and 3 molars, making a dental formula of 2.1.2.3. The chimpanzee shown below is an Old World anthropoid species and, therefore, has a catarrhine dental formula.
Although the practice of collecting animals have been present since 2500 B.C (Dunlap and Kellert), efforts to keep animals in a safe and natural habitat have been poorly consummated. Psychological manipulation has consequentially drawn chimpanzees to mental illness, as in the article “How Abnormal Is the Behavior of Captive, Zoo-Living Chimpanzees?” Lucy P. Birkett and Nicholas E. Newton-Fisher wrote, “Many chimpanzees (Pan troglodytes) kept in laboratory housing settings show a variety of serious behavioral abnormalities, such as, repetitive rocking, drinking of urine, or self-mutilation.” Social and maternal separation for the benifit of reasearch are linked to psychological traumatic as well (Dunlap and Kellert). Although through history the service of zoos have been for entertainment, it is a trivial reason for holding chimpanzees in confidment. Subsequently, it is inhumane to take primates from the wild and place them in a zoo, commercial, or laboratory setting, which strips them of their ability to act naturally.
In 1996 Kevin Hunt proposed a feeding hypothesis on why bipedalism ocurred. It stated that 80% of the time chimpanzees feed, they are exhibiting a bipedal locomotion (Jacobs, 90). This occurs when chimps feed o...
1.) Quadrapedalism- Using all four limbs to support the body during locomotion. The majority of quadropedal primates are arboreal, such as the bearded saki, there are some terrestrial quadropedal primates though, such as the savanna babboon. Typically, the limbs of terrestrial quadrupeds are of equal length. In arboreal quadrupeds forelimbs are shorter and may be 70-80% as long as the hind limbs.
3.Body mass for 109 primate species. For 23 species with sample sizes of nine or more for each sex, dimorphism (male/female ratio) in neonatal body mass range from 0.94 in Galago senegalensis 1.19 in Pongo pygmaeus. Dimorphism in neonatal body mass was absolutely connected both with adult body mass and with dimorphism in adult body mass, but the obvious relationship with adult
Chimpanzees are part of the non-human primate group. Though we share a common ancestor, evolution has pushed us in different directions. However this common ancestor causes humans to be curious about these creatures. As discussed in Jane Goodall’s video Among the Wild Chimpanzees we were once considered to be human because of our use of tools but once we observed these non-human primates using tools, this perception was changed forever. The question now at hand is if having the chimpanzees that we study in captivity makes a difference between studying wild chimps. These interesting creatures can be found naturally in the rainforests of Africa.
All in all, learning about primates then getting to observe them is very interesting. I got to match the primate’s behaviors written in a book with how they act in person, and see for myself if it was what I expected. Observing them is far more fun than just reading about them, for example while I was sitting with the orangutans there was not a minute that went by where I wasn't smiling or laughing at what each individual ape was doing. Actually seeing certain primates interact with each other whether it be grooming, hugging,or playing, put into perspective just how much they act like humans. By observing and doing research, this will better our understanding between the differences and similarities of non-human primates and ourselves as humans.
In order to show off how powerful one chimpanzee is, the male can swing, pull down the trees, drag them, throw sticks and stones, and stomp on t...
From our loving pets that welcome us home every day, to the birds chirping in the morning, to the exotic animals we admire; animal safety and animal rights is a priority that gathers attention across the world. Being up close and personal with animals is a coveted experience that zoos try to bring to everyday life. While it is breathtaking to see these glorious animals it can possibly bring danger to their lives and call into question someone’s morals. The Denver Zoo claims that they rescue endangered or suffering animals from hostile environments and bring them into a safe, nurturing facility where they cater to the animals’ needs. With the demands of the people it is truly amazing that the Denver Zoo can properly care
The Zoo and Its Benefits Zoos bring humankind closer to wildlife. Though, sometimes that means taking the animal out of its natural habitat. Some animals have lost most of their habitat and are on the verge of extinction. In this way, the zoo helps the animals rather than using them as a form of human entertainment. Zoos also allow humans to study different kinds of animals more closely.
