Causes of biodiversity losses :
(i) Habitat loss and fragmentation.
(ii) Over-exploitation.
(iii) Alien species invasions.
(iv) Co-extinctions.
Co-extinctions : When a species becomes extinct, the plant and animal species associated with it in an obligatory way also become extinct. When a host fish species becomes extinct, its unique assemblage of parasites also meets the same fate. Another example is the case of a co-evolved plant pollinator mutualism where extinction of one invariably leads to the extinction of the other.
