Over the recent decades, the society has faced extinction in most of the primates that existed in the ecosystem. However, some of the monkey species still exist, especially in savannah and tropical rain forests. The analysis focuses on a unique species of monkey - Sumatran Orangutans - that is commonly found in Indonesia. It is one of the endangered species that exist in the ecosystem.

Gursky-Doyen, S. & Supriatna, J. (2010). Indonesian Primates, London: Springer

The authors analyze the population of various monkey species, with much emphasis on Sumatran Orangutans. Although the species is commonly found in Indonesia, Brazil has experienced high population of the primates. Among the 33 species of primates available across the world, Orangutan tends to be the common species across the society. The book outlines the key aspects, and characteristics of Sumatran Orangutans' species. In addition, it provides an analysis of an environment that suits the species. Indeed, in Indonesia, only two distinct areas are good habitat for this species. In conclusion, the book is relevant when researching for the conservatory issues relating to Orangutan's monkey species.

Caldecott, J. O. & Miles, L. (2005). World Atlas of Great Apes and their Conservation, New York: University of California Press.

Caldecott and Miles provide an analysis of the common apes that are in the verge of extinction across the society. Though it has been ignored for a long period, monkey species plays a key role in income generation through attraction of tourists from overseas. The book provides comprehensive analysis of other five monkey species including lowland gorilla, bonobo, eastern gorilla, Bornean Orangutan, and chimpanzee. It provides a critical analysis of the behavior of monkeys and ecological requirements for their survival. In addition, the book is full of illustration on the societal activities that characterize the life of the monkey species. Its analysis ensures that an individual is imbibed with knowledge on the trends and characteristics of these apes.

United Nations Environment Programme. (2007). The Last Stand of the Orangutan: State of Emergency: Illegal Logging, Fire and Palm Oil in Indonesia's National Parks, Nairobi: UNEP

The UNEP publication on Sumatran Orangutan was carried out in an attempt to analyze the population and adaptability of this species of monkey. Great Ape Survival Partnership was concerned on the predicament that befalls Orangutan. The report was compiled with the assist of the satellite information in order to postulate the exact number of Orangutan that was still available in the ecosystem. From the survey undertaken, it is clear that the ecosystem and habitat of the primates are being interfered with through illegal logging, plantation crops undertaken across Indonesia, and deforestation. Although palm oil has been evident as the most reliable Cash crop for Indonesians, there is need to preserve National Parks in order to conserve these endangered species.

Schaik, C. (2004). Among Orangutans: Red Apes and the Rise of Human Culture, Harvard: Harvard University Press

Schaik portrays a pictorial representation of the importance of Orangutans in the human culture. The book provides a critique of how human population has negatively impacted the lives of the primates. The author describes the characteristics of Orangutans as having a red hair, which is unique among other Apes. The book provides an insight on the nature of disappearance of the leading endangered species; Sumatran Orangutan. With the advent of new technology across the globe, mankind has enacted strategies to clear the habitat for these endangered species. The author provides an analysis on the temperaments and personalities of these animals. It highlights the key features that are visible in all the species of Orangutan.

Corlett, R. & Primack, R. (2011). Tropical Rain Forests: An Ecological and Biogeographical Comparison, London: John Wiley & Sons

Written by Corlett and Primack as their first edition, the book focuses on the ecological and biogeographical comparison of the habitats of Orangutan species. Ideally, tropical forests have been deduced to be conducive for Orangutan and other monkey species in the ecosystem. Some of the rainforests that have different habitation include tropical Africa, America, Southeast Asia, New Guinea, and Madagascar. Though there has been isolation among these environments, a number of Orangutans species have been spotted across these regions. The book focuses entirely on the effect of rain forest in accommodating this species. It highlights the effect of the rain forests on the species. Illustrated with colorful drawings, the reader finds it enjoyable to read, and understands the effect of rainforest on the habitat's ecosystem with ease.

Nijman, V. (2009). An assessment of trade in gibbons and orangutans in Sumatra, Indonesia, London: Routledge

Nijman, in his book, has provided an analysis on the transaction involving orangutans and gibbons across Indonesia. The population of these primates has been adversely affected, and it is predicted that in the near future, the population will be extinct. Most of the poachers and predators are aiming at the endangered species, and the book highlights the strategies in which the Indonesian government can undertake in order to minimize the adversity of the situation.

The authors provide a coherent analysis on the distribution of Orangutan across the society. Speculation has surrounded most of the theories that the species have declined tremendously over the past decade. In an attempt to ascertain the relevancy of the speculation, the book provides an analysis on the population distribution with the help of Markov model. Although natural selection has played a vital role in enhancing equitable distribution of population in relation to the available resources, human atrocities has enhanced the adversity of the situation.

Batt, E. (2012). SOCP: Orangutans gone by end of 2012 unless deforestation halted. Digital Journal, 2, 156-198

The author analyzes the effect of deforestation on the population of Orangutans. Ideally, Batt stipulates that the population decline of Orangutan is based on deforestation. Over the past decade, deforestation has been rampant, and it has caused migration of the endangered species. The book outlines strategies that can be used to combat deforestation in an attempt to save the lives of these primates.

Van Noordwijk, M. A. and van Schaik, C. P. (2005), Development of ecological competence in Sumatran orangutans. American Journal Physical Anthropology, 127, 79-94.

The authors provide a data on the ecological competence of the Sumatran orangutans' species. It is estimated that the swampy forest provides an interbirth of about 8 years. The data provided enables the readers to ascertain the reliability of the locomotor independence. Following this analysis, the reader can ascertain the effectiveness of ecological setting and its underlying features

Smith et al. analyzed dental thickness of the Sumatran Orangutan and Bornean in an attempt to ascertain whether they are similar or different. The significance of the analysis portrays a crucial role in determining the age of the primates. Dental thickness have always been used by many researchers in determining the similarities and differences between various endangered species.
