Amphibians are more vulnerable to extinction as compared to other animal groups because
(i) Habitat Fragmentations: It refers to isolation of a few areas by habitat modification. Small populations that survive within such fragments are often susceptible to inbreeding, genetic drift or extinction due to minor fluctuations in the environment.
(ii) Large Scale Climate Changes: These changes can modify aquatic habitats, preventing spawning in amphibians.
(iii) Habitat Modification or Destruction: Amphibians generally need aquatic as well as terrestrial habitats to survive; threats to either habitat can affect populations. Hence, amphibians may be more vulnerable to habitat modification than organisms that
