Predation By Gambusia Holbrooki (Girard) (Pisces Poeciliidae) On Tadpoles : Feeding Trials And Microhabitat Utilisation In Two Contrasting Wetlands On The Swan Coastal Plain, Western Australia, Beate Sommer
Theses : Honours
Predation by non-native Gambusia spp. (somewhat inappropriately referred to as “Mosquitofish”) has been implicated in the decline of some frog populations overseas and in eastern Australia. Originally introduced to control mosquito larvae, Gambusia holbrooki are now widely distributed and abundant in wetlands of the Swan Coastal Plain (Western Australia). Anecdotal evidence suggests that some frog populations on the Swan Coastal Plain may be declining. Through a series of laboratory feeding trials and a field survey conducted in a permanent and a seasonal wetland on the Swan Coastal Plain, this study investigated whether predation by G. holbrooki has the potential to …
