weaken organisms and interfere with metabolic function. As a result, faunal

species can suffer from the ability to find food, find and attract a mate, seek shelter, migrate, or engage in fertile outcome in the breeding process. The deficiencies in these basic functions may lead to premature deaths of considerable numbers of the population or in the reduced fecundity and birth rates. Correspondingly bacterial infections, viral introductions and infection by higher level parasites may be a contributory cause to species extinction.
