Review History of Systems Ecology Egypt Changed Since 6000 Years Ago

History of Systems Ecology Egypt Changed Since 6000 Years Ago
Findings animal pictures on an ancient Egyptian artifact notes explain some ecological systems of large mammals that ever lived in the Nile Valley for approximately 6000 years. This text shows that the extinction of species may be due to the dry climate and human population growth in the area and has made increasingly less stable ecosystem.

of research results discovered by science experts published in the journal Proceedings of the National Academy of Sciences (PNAS) 8 September 2014 edition of the scientists involved found a lot of local mammalian species extinction causes a decrease in the animal population and stability in the Nile Valley. Justin Yeakel a graduate student from the University of California (Santa Cruz) explains the variety of species that live amongst the people, the loss of one of the species at that time had little impact on the function of ecological systems, but the current increases and the impact is much more sensitive.

Amendment the Nile Valley Systems Ecology, Ancient Egypt 

of analysis which has been started since 2010, when it was when Yeakel visiting the Tutankhamun exhibition in San Francisco with Nathaniel Dominy, an associate professor of anthropology at UC Santa Cruz and Dartmouth. They realize that there are very important infromasi written in ancient artifacts and trying to peel the contents of the text to predict changes in the ecological system of ancient Egypt, especially around the valley of the Nile. Paul Koch paleontologist who participated in this research team, he formulated the theory approach to look at the ecological consequences of changes in species. The team of scientists also perform computational analysis of network dynamics predators of ancient Egypt.

About 6000 years ago, 37 species of large-bodied mammalian are estimated to live in Egypt but today only 8 remaining species. Among the species of ancient texts written in Late predynastic period (before 3100 BC) is no longer found in Egypt, including lion, wild dog, elephant, deer, and giraffes.

According Yeakel, previously diverse mammal communities are very different now, because of the number of species decreased to one of the main things the loss of ecological redundancy system. Some species of deer and other small herbivores are considered important because so many different predators prey on them. When small herbivores less, the loss of one of the species has a much larger effect on the stability of the system and can lead to further species extinction.

This study is based on records collected zoologists Dale Osborne, in a book published in 1998 entitled 'The Mammals of Ancient Egypt "which describes a detailed picture of the animal population in the area of ​​ancient Egyptian history based on archaeological and paleontological evidence and historical records. Dale Osborne remarkable database compiled when species are represented in the form of artifacts, and how changes in ecological systems over time. Given this data, the scientists used ecological modeling techniques to explore the consequences of these changes.
