Abstract: | The American bullfrog (Lithobates catesbeianus) has been introduced throughout the world over the past two centuries. This taxa is a potentially devastating invader because of its large size, prolific reproductive output, and broad ecological niche. Consequently, the extent of this ongoing biological invasion is an increasing conservation concern. In Argentina, several introduced populations have been reported. In most cases, these introductions have been intentional or incidental releases from breeding facilities, yet the consequences and effective controls for captive-breeding programs have not been assessed by government environmental agencies. Further studies are needed regarding the trophic ecology, reproductive biology, ecological niche, and chytrid fungus infection prevalence to predict the ultimate impacts of this species on native ecosystems. The aim of this work is to report a new alien population of L. catesbeianus at La Candelaria, Salta province, Argentina. This record represents the first population of American bullfrogs detected in northwestern Argentina. |
