简介
- The American bullfrog, Lithobates catesbeianus (Shaw, 1802), is considered one of the world's worst invaders because of its potential to affect native fauna adversely, especially amphibians, through predation, competition, breeding interference, and disease transmission.
- Here, the potential impact of introduced American bullfrogs (juveniles and adults) on native adult green frogs, Pelophylax kl. esculentus (Linnaeus, 1758), was investigated in a pond ecosystem by means of stomach‐content and stable‐isotope analyses. Specifically, this study was aimed at assessing the impact of the American bullfrog on native green frogs in terms of predation and competition (i.e. feeding ecology and habitat use), and uncovering changes in interspecific interactions linked to the ontogenetic dietary–habitat shifts of the invaders.
- Stomach contents and isotope analyses suggest that L. catesbeianus changes trophic position in the …
