Speciation

1. INTRODUCTION
TO EXOTIC
SPECIES

2. EXOTIC SPECIES,
also known as alien species, invasive
species, non-indigenous species, and
bio invaders, are species of plants or
animals that are growing in a non-native
environment.

3. • Alien species have been moved by humans to
areas outside of their native ranges. Once
transported, they become removed from the
predators, parasites, and diseases that kept them
in balance in their native environments. As a
result of the loss of these controls, they often
become pests in the areas into which they are
introduced.

4. Species originating from particular area,
introduced into new natural environments
can lead to different forms of imbalance in
the ecological equilibrium.
