Abstract:
The extinction of different species from the earth is increasing at an alarming rate. So, assessment of probability of extinction of different important species in our ecosystem could help us to take proper conservation policy for those population whose chance of extinction is high. In this paper a method is developed to find the probability of extinction of populations in a general n-trophic food chain model under demographic stochasticity. The birth-death process is used to incorporate the demographic stochasticity and the necessary mathematical expressions are obtained. The theoretical finding is validated by numerical simulation for a two dimensional predator-prey system.

Fossils of organisms that were different from anything alive today had been documented as early as the 17th century, but it was not until the early 19th century that scientists began to recognize that the successive layers of fossil bearing rocks were like successive pages in the history of life on earth. Although this recognition gave rise to the birth of the field of paleontology, the idea of complete global extinction of a species had yet to be fully accepted. At...
