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
Chimpanzees make tools and use them to procure foods and for social exhibitions; they have refined hunting tactics requiring collaboration, influence and rank; they are status cognizant, calculating and capable of trickery; they can learn to use symbols and understand facets of human language including some interpersonal composition, concepts of number and numerical sequence and they are proficient in spontaneous preparation for a future state or event.
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...
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.
...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.
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.
Primates, any placental mammal of the order Primates, normally having flexible hands and feet and, in the higher apes, a highly developed brain (“Primate”, 2016), have been one of the most popular animals and prominent attractions in zoos.
5.) Primates and all mammals share a series of characteristics such as: body hair, long gestation and live birth, mammary glands, different types of teeth, ability to maintain a constant body temperature, increased brain size and a considerable capacity for learning. Scientists created a special order called primates, because they share many characteristics unique to their order: a tendency toward erect posture, a flexible, generalized limb structure, hands and feet w/ a high degree of apprehensibility, retention of 5 digits on hands and feet, an opposable thumb, nails instead
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
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.
I observed chimpanzees in the Kimberly-Clark Chimpanzee Forest exhibit at the Dallas zoo. These African apes, like humans, are hominoids and fall into the larger category of catarrhines. Their scientific classification is Pan troglodytes. There were about ten chimpanzees in that habitat. Most of them were grown adults, except two children. They were robust and had black fur. The average weight of the chimps was listed on a display to be about 115 pounds.
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.
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.
Dr. Dave Hone (2014) proudly honors the title of being in the pro-zoo camp. Hone was a volunteer for a number of years at two different zoos and is able to identify zoos as being more than just a collection of animals (Hone, 2014, para. 2) He firsthand witnessed the importance of how conservation assists with preventing species from going extinct, the role education plays to inform many children and adults along with the guidance research shares to help better understand wildlife (Hone, 2014). In order to ensure that wild animals receive maximum care it is crucial to gain beneficial knowledge from research. In addition to understanding animal breeding through research, zoo officials are able to learn how to prevent and cure a variety of animal diseases. Education is another positive resource that zoos have to offer. There is always the option to learn about wild animals through animal documentaries, however many people enjoy a prominent up-close personal
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.
