Question:

What could be the possible explanation for greater vulnerability of amphibians to extinction as compared to other animal groups?

Answer:

Amphibians are more vulnerable to extinction in comparison to other animal groups, there are following reasons:

  1. Amphibians generally lives on both aquatic and terrestrial habitat for the survival; threats to one of the either habitat affects population. So they could be more vulnerable to habitat modification.
  2. Habitat fragmentation means habitat divided into small fragments or pieces through habitat modification. Small population that survives in that division within these fragments are capable of doing inbreeding, genetic drift or show extinction due to small fluctuation in the environment.
  3. Climate changes modify aquatic habitat on the large scale which prevents amphibians from spawning (to deposit or release eggs).
