Study of amphibians.
Living amphibians (Class Amphibia, Subclass Lissamphibia) include frogs (~5,600 currently recognized species), salamanders (~570 species), and caecilians (~175 species). Most information concerning declines and 45 extinctions has come from studies of frogs, which are the most numerous and by far the most widely distributed of living amphibians.

The impact on the amphibian is unclear, but a recent study suggests that there is a negative effect. Analysis by McCarthy and Parris (2004) found that toe clipping reduces the return/recapture rate of frogs by 4 to 11% for each toe removed after the first.
Pollination and seed dispersal are determinants for plant survivorship. Among land vertebrates, mammals and birds stand out in these relationships with plants. On the other hand, frogs are not expected to play a role in these interactions, as nearly all species are carnivorous (mostly insectivorous) after metamorphosis.
