Observaciones sobre la dieta de la culebra de agua Thamnophis hammondii en un oasis de Baja California Sur, México
Luja, Víctor H. | Rodríguez Estrella, Ricardo | Sinervo, Barry
Information is presented about the prey consumed by the two-stripped garter snake Thamnophis hammondii in a mountain oasis in Baja California Sur, Mexico. The diet of this threatened snake includes the Baja California treefrog Pseudacris hypochondriaca curta (native species), as well as an exotic fish: the red bellied tilapia Tilapia sp. cf. zilli. This exotic species has become invasive in Baja California Sur oases, displacing native fishes and becoming an important dietary resource to T. hammondii.
