摘要: Recently, Clavero et al. (2008) found a negative relationship between the stability of water courses and occurrence fishes in otter diet. We studied diet place mainly temporary form small ponds streams strongly dependent on rainfall. Our results constitute extreme gradient instability, where otters do not prey upon fish but depend crayfishes diving beetles to survive.
