Tropical rain forests, which are found in Africa, South America and Southeast Asia, have warm, humid climate and heavy seasonal rainfall (Supriatna et al. 1996; Umapathy et al. 2003). The rainy season lasts from about September to May, with average monthly rainfall between 140 and 300 mm (5.5 and 11.8 in) and from June through August or September there is less rainfall received in Southeast Asia (Lucas & Corlett 1991; Yeager 1996; Umapathy et al. 2003). Besides, tropical rain forests are home to world’s highest biodiversity including a highly complex and diverse vertebrate fauna (Harmelin-Vivien & Bourliere 1989). However, tropical rain forests are always manipulated and exploited for economic purposes (Mergen, 1981). The tropical rainforests …show more content…
Primates are one of those adversely affected vertebrate taxa and therefore are recognised as indicator species that may reflect the intactness of the forest as wildlife habitat. For instance, the population decline of various primate species has generally altered the ecological balance of the biological community in Malaysia (Marsh et al. 1981). It is believed that the greater the species richness of a species group, the more sensitive it is to habitat change and thus, the more useful it can be as an indicator of changes in ecosystem processes. Since the survival of most primate species is dependent on the well-being of rain-forest habitat (Wolfheim, 1983) and that most of the rain forests throughout the world is expected to be reduced to logged or otherwise disturbed patches within 25 years, the abilities of primates to survive in those areas are of great importance in formulating conservation strategies. (Johns & Skorupa, 1986). Hence, information on primates is very important (Johns

Climate change influences nonhuman primate evolution in a number of ways. Fore example, in Central Asia, climates increased temperature by an insane amount. However, the issue among primates became that it was too dry of an environment and they were not able to survive. Primates among the northern hemisphere pretty much disappeared as a result of the increase in temperature of that period. Additionally, in South Asia and East Africa, tropical rain forests were being taken out and instead they would have grassy woodland areas, much less wet than the environment they replaced.
The climate and it's different variable had many effects on the evolution of primates. It's obvious that when the weather changes, migration is necessary. When the weather changed, primates had to migrate, causing adaption to different environments. With each migration, new habitats were exposed to primates, giving them new ways of life. Enviornment change exposes new foods and new living accomidations.
Did you know that there is numerous species that are endangered and becoming extinct? One terrestrial mammal that is experiencing threats to their extinction are lemurs, this jeopardized spices' is most common in our zoos today then in the wildlife. African islands including Madagascar is their natural habitat, and studies demonstrate that is their only home in the world because the geographical location is isolated. There are different kinds of lemurs and some of the most common ones that we know today are: the ring-tailed lemur (Lemur catta) , silky sifaka, mouse lemurs. The scientific name for lemurs is “Lemuroidea”.
Through history there has been evidence to help support the claim that climate change has influenced the evolution of primates. Scientific evidence has proven that during certain climate spikes such as the swamp age, apes in the given territories that encompassed Africa led a migration to the Asia and Europe territories. The same climate changes that was responsible for the creation of the Swiss Alpes and other phenomena, has been associated with the adaptation, extinction, and migration. As weather changed in certain areas, the land became more dry making it harder to obtain and hunt food. Climate change, in theory, led to the extinction of the Sivapithecids apes because of the inability that the species has to obtaining food.
Not everyone agrees with the GAP’s but some people do have special obligations for the great apes. Great apes are our closest relatives. Former animal researcher Roscoe Barlett researches about primates and wants to extend the rights for the animals. Kevin Martin,
The ecosystem that I found to be the most interesting is the Daintree Rainforest. This rainforest is estimated to be 180 million years old and has a very fascinating and distinctive land. The Daintree Rainforest is a tropical rainforest that is located on the north east coast of Queensland, Australia; taking up a total of 0.1 percent of Australia’s land mass. The Daintree Rainforest is the oldest existing tropical rainforest in the world and the biggest rainforest located in Australia, it is a total of over 1,200 square kilometers in size. This forest got its famous name from a man named Richard Daintree, a 19th century Australian geologist and photographer.
Deforestation results in the loss of biodiversity Deforestation is having its most devastating effect on biodiversity in tropical rainforests. The destruction of millions of hectares of forests by human activities means: • The removal of the bases of numerous food webs • The loss of habitats for many species of flora and
Introduction: Description: Deforestation is defined as the permanent destruction of forests in order to make land available for other uses. According to the Food and Agricultural Organization of the United Nations (FAO) 18 million acres of forest are lost each year. This equals to approximately 36 football fields of forest being cleared each minute. Though deforestation occurs all over the world, it’s the tropical forests which are being particularly targeted. Due to this countries such as Indonesia, Brazil, the Democratic republic of Congo and Thailand have a very
The biggest overt difference that one notices when comparing nonhuman primates to human primates is the loss of body hair in the modern human, to the extent even, that humans have been described as the “naked ape” in many contexts. The primates classified as old world apes that are closest in relation to humans are the Bonobos and Chimpanzees. Looking specifically at the Chimpanzees, we can compare and contrast the properties of the skin and hair between them and humans to get an idea of the evolutionary pressures that may have been in place. Notably, there are many different properties of the skin in the nonhuman and human primates.
Even so, if there are 100 million species currently in existence, we are losing between 10,000 and 100,000 each year.” No matter which numbers are accurate, mislaying of biological diversity is a very serious-minded problem - and it seems to only get worse every single day. Unfortunately, an overwhelming volume of the earth 's biological diversity is in the equator region, a field tortured by extreme poverty and thus under serious risk of species loss. Conservation International has appointed 34 distinct regions as "biodiversity hotspots," areas that grip at least 1,500 classes of vascular plants (> 0.5 percent of the world’s total) as endemics, and have lost at least 70 percent of their own habitat. These 34 hotspots fill in only 2.3 percent of the Earth 's land surface, and eventually host over 50 percent of the world’s plant classes and 42 percent of all terrestrial vertebrate classes as endemics.
Without the transpiration of trees, deforested areas become drier. Changes in weather and shelter cause deforested areas to undergo a tremendous loss of biodiversity. The scientist hasn’t even come close to testing 1% of the plants in the tropical rainforests for medicinal use, but they regularly discover species that are helpful to us the people. But, these forests and their potential benefits are looking like they may disappear by the end of this century if we don’t stop
