Introduction:

The ecologists and other scientists use the extinction vortices (models) to categorize the extinctions as per their causes and to understand their dynamics. Four classes of these models were created by ME Soule and ME Gilpin in the year 1986. The R and D classes deal with the environmental factors like pollution, disturbance, and habitat loss, which affect the ecosystem. The F and A classes deal with the genetic factors like genetic drift, interbreeding, and breeding depressions, which affect a population of an organism and the ecosystem as a whole.
