Diet of invasive clawed frog Xenopus laevis at Lage stream (Oeiras, W Portugal)
We present data on the trophic ecology of Xenopus laevis, introduced in two streams at Oeiras, Western Portugal. During 2007, we captured and euthanized 70 individuals during two field seasons (July and September) in one stream. The diet included a wide variety and size range of mainly benthic prey, with water snails (Physidae) being the most important. Xenopus laevis also preyed on native fish and amphibians. There were differences in the diet between sexes (males showing higher prey diversity). Our results demonstrate the ability of this exotic amphibian to adapt to a wide range of conditions.
