A Research Study On Primate Conservation

A few weeks ago, I spent a lovely Monday afternoon observing two different primates at the Santa Ana Zoo. I got to the zoo around two in the afternoon, and to my surprise, the zoo was decently crowded. The Santa Ana Zoo is smaller in comparison to other zoos like the Los Angeles Zoo, but still had a decent amount of animals there. Covering a small 20 acres of land, I came across two primates that fit perfectly for the purposes of this course project. I chose to observe an endangered ape, the white-handed gibbon, and an endangered new world monkey, the golden-headed lion tamarin.

Primates are one of the most interesting mammals on earth, not only because of their complex social structures, but because they hold so many similar characteristics to humans. Primates are often cited as our closest living relatives and on two separate occasions I observed four separate species of primates at the San Diego Zoo that can justify their use of their physical characteristics and behaviors that may be similar as well as different to the other primates and ours.

Habit loss has been one of the most prominent issues regarding the animal kingdom, and now it seems like the human race is trying to rid our earth of the decreasing amount of flora in certain areas. In Indonesia rain forests are being torn apart to make way for palm oil plantations. Although palm oil is used in packages foods and cosmetics, the Sumatrans elephants and orangutan are suffering from the habitats loss. (Corwin, 8)

This book was about the life of apes in their natural habitat that is being destroyed. Stanford highly pushed the idea of extinction and what people are doing to the apes. Stanford explains the threats to the ape's survival and tells us ideas that could help stop or slow down the decline of the ape population. He tells us about the complex cultural, social, economic and

Orangutans have long lifespans (30-40 years) with long interbirth intervals and low reproductive rates. In fact, females have eight year intervals between births and will only give birth to one or two offspring in her lifetime. The reason why this poses a problem is that when an enormous amount of orangutans are killed, it’s tough to recover because they are not producing large numbers of children nor do they have short interbirth intervals. Consequently, there will be extremely high death rates and very few births (UNEP, 2007). Their population numbers will continue to fall because they won’t be able to compensate for the great loss. A study completed by Michael Bruford and Benoit Goossens at Cardiff University showed that in 1900, there were approximately 315,000 orangutans in Indonesia. Currently, there are about 60,000 orangutans living in the forests of Indonesia, which is a massive population decline (Kaye, 2016).When orangutans are driven out of their habitat due to deforestation and illegal logging it forces them to roam a great distance in search of food. Orangutans are solitary creatures, spending the majority of their time in the trees. Their diet relies mainly on fruit, with a preference for fruit with soft pulp. They also eat buds, flowers, leaves, soil tree bark, and some insects. Due to their largely frugivorous diet, they have to monitor the seasonal availability of resources. When fruit is abundant, they will increase their food intake and store the food as fat for energy. This enables them to eat low quality food items in habitats where fruit may be scarce (Delgado & Van Schaik, 2000). The dipterocarp forests of Borneo and Sumatra have trees that fruit simultaneously, so there is an abundance of fruit once every 2 to 5 years which are known as the “mast years”. During the other years there is not as much fruit, so orangutans have to maintain large home ranges in

I primarily observed three orangutans, one male, one female, and one juvenile, of Sumatran and Bornean descent, scientifically known as Pongo abelli and Pongo pygmaeus, respectively, and to a lesser extent, two gibbons known as siamangs, or Symphalangus syndactylus. These primates share the same enclosure in the San Diego Zoo in California. I observed the orangutans from 12:58 P.M. to 2:00 P.M. CST on September 19th. During this time frame, the three orangutans mainly stayed high up in their man-made structures, consisting of multiple metal bars covered with nets, ropes, and hammocks. The female and juvenile orangutans stayed above ground from 12:58 P.M. to 1:31 P.M., and again from 1:48 P.M. until 2:00 P.M, approximately 45 minutes. During

There are many examples of iconic animals that we take for granted when it comes to thoughts of sharing our earth with them in the far future, but it is becoming more evident throughout the passing of time that this will no longer be true with current conditions. When it comes to animals becoming extinct not many people think that many recognized animals, besides the most talked about ones like Polar bears and Giant pandas, are at risk. One of these incredibly recognized endangered animals is the Orangutan. One of the most distinguished of the great apes, both of the subspecies of Orangutan are endangered; The Bornean and the Sumatran, with the Sumatran being declared as a critical species.

The primates species that I observed were the Bornean orangutans and the Sumatran orangutans. There were three adult females. one adult male, and one infant female. The orangutans were observed at San Diego zoo’s ape webcam on April 26, 2106.

Primates first evolved from the trees of tropical forests, later to the ground. Through the times of prosimians to human, many characteristics has been represented due to the adaptations to new environments and resulted in evolutionary changes. The Earth has encountered several geological and climatic changes over time. For the primates existed at that time had to adjust itself especially in body configurations and locomotion in order to better survive. It is important to be aware of this information since we are the part of occurring changes as well. Throughout the evolution owing to the transforming environments interacting with natural selection, primates developed their own ways to move better (meaning changes in locomotion) with different types of bodies (meaning changes in body configuration).

My observation of the orangutan habitat was on a sunny and hot day with the average temperature being between 65-70F. The Enclosure for the orangutans was a grassy and dirt area that was approximately 35ft+ in width and about 75ft+ in length with a long glass barrier for observation. The habitat featured three 15ft tall fake trees which were fashioned after a tree but bare of leaves. The trees were

The Jane Goodall Institute website provides information about the projects regarding the protection of chimpanzees and other primates. Based on the institute’s initiative to protect the primates by providing education to the community, supporting sanctuaries, and working with law enforcements (website JGI). Furthermore, the information provided on the program Roots & Shoots points out a guide to those interested in helping the wild life, and provides aid to elaborate new plans to help the primates. The first step is to acknowledge the problem, in this case is finding a way to protect the chimpanzees. Second, to elaborate a pan, the JGI conservation program uses technology such as cloud computing and remote sensing to provide up to date information on the

Historically, as for other lemurs, the greatest conservation threat to the silky sifaka has been cultivation of hill rice through slash-and-burn agriculture. Although human hunting of primates in Madagascar is generally less widespread than in Africa or Asia (Conservation Education et al. ), nevertheless in some parts of Madagascar, such as Marojejy National Park, steady lemur poaching is evident. Erik R. Patel therefore began a conservation education program in collaboration with local authorities, the Peace Corps, and Cornell University, with the support of the Conserva- tion Committee of the American Society of Primatolo- gists.

Palm oil harvest often leads to deforestation of the rainforests, and raises many ethical concerns from the public, (Levitt, 2015).

Agriculture is the leading cause of deforestation because as human population grows the need for agricultural products increases. Unfortunately, the land used for cultivation results in the displacement of tree reliant animals such as the orangutan. “Without forests, orangutans cannot survive” (Galdikas). Palm oil is produced from trees grown in large plantations in regions where tropical rainforests once existed. The orangutans’ way of life revolves around the existence of trees, they nest in trees, drink water out of holes, and eat their fruit. Orangutans also

In the article Impacts of Hunting on Tropical Forests in Southeast Asia, by Harrison and others, the authors examine how a wide variety of factors have influenced hunting practices in Southeast Asia and led to a rapid decline in animal populations in the region. According to the criteria outlined by Clark, the problem in this article is well defined: the practices employed by hunters are unsustainable and indiscriminate, destroying large numbers of vulnerable and rare animal species. Solutions must be found to protect these species while also respecting the cultural rights of those to hunt.
