Do African Clawed Frogs like Led Zeppelin?

African clawed frogs are effective global invaders due to their adaptability to diet and habitat type. It can be challenging to eliminate these frogs from the environment, as they are escape artists and tend to move overland like grease lightning. This study aims to test whether an alternative control measure may be used to get rid of the African clawed frogs. We will expose them to a noisy environment, in the hope that makes them uncomfortable enough to leave the pond. The question thus lies with whether clawed frogs prefer Eminem, Metallica, or perhaps some classical Mozart?

Fastidious frogs: do African clawed frogs avoid ponds that contain fish?

The African clawed frog, Xenopus leavis, is a highly invasive amphibian, native to sub-Saharan Africa. Anecdotal observations suggest that these fully aquatic frogs actively avoid fish. For my honours project I will be thoroughly investigating this observation. I will use an experimental setup to try and determine what cues the frogs use to detect the fish in ponds and if they are more likely to avoid some fish species (native) over others (invasive). The outcomes of this study may help us with the management of these frogs in parts of the world where they are unwanted by providing a biological solution to help stop invasion.
