a: amphibians ~
b: canaries in a coal mine
What:
'Amphibians are like canaries in a coal mine in that, they are the most vulnerable visible organism and (their high mortality rate) is an early warning sign that ecosystems are not healthy,' said Soule. They are vulnerable because they require two different kinds of habitat -- aquatic and land habitat -- and are susceptible to any environmetal change in either one.
