Linking aquatic and terrestrial environments: can beaver canals serve as movement corridors for pond-breeding amphibians?
Beavers Castor canadensis are well known as ecosystem engineers for creating ponds by damming streams. However, in wetlands with soft substrates and shallow banks, beavers often dig networks of foraging canals, the ecological effects of which have received little study. We examined how canals are used by pond-breeding amphibians during dispersal and migration between aquatic and terrestrial
