Genealogical Studies Of Selected Australian Barramundi (Lates Calcarifer) Using Mtdna : Implications For Stock Transfer To The Kimberley Region Of Western Australia, Robert G. Doupe
Theses : Honours
This study resulted from concerns for the present and proposed movement of barramundi (Lates catcarifer) across presumed population genetic boundaries into the Kimberley region of Western Australia for net-pen aquaculture and a recreational fishery development in dams no longer available to seasonal barramundi dispersal. Direct DNA sequencing of the non-recombining, maternally inherited mitochondrial genome of barramundi thought to represent wild populations from a broad section of a still wider Australian range were used for phylogenetic reconstructions that support hypotheses for historic gene flow between Kimberley and other populations during Recent sea level fluctuations. Nil or low levels of genetic diversity …
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 …
