A Study Of The Effects Of Probait On Chuditch, Dasyurus Geoffroii, Within The Julimar Conservation Park With Notes On The General Ecology, Melissa York
Theses : Honours
Broad scale fox baiting programs have been underway in Western Australia since 1996 when the Western Shield fauna recovery program commenced with the aim of recovering many fauna species that are under threat of extinction. Until recently, effective fox control for fauna recovery has been achieved with dried meat baits impregnated with the poison 1080. The Department of Conservation and Land Management (CALM) has developed more readily available and cost effective sausage meat baits, termed Probait. As bait acceptability trials in the laboratory indicated a potential risk from Pro bait ingestion by chuditch (Dasyurus geoffroii), assessment of the likely risk …
The Systematics Of The Reducta Complex Of The Burrowing Freshwater Crayfish Engaewa Riek, Quinton Burnham
The Systematics Of The Reducta Complex Of The Burrowing Freshwater Crayfish Engaewa Riek, Quinton Burnham
Theses : Honours
The south-west of Western Australia is home to an endemic genus of obligate burrowing freshwater crayfish, Engaewa Riek. Riek (1967) first described three species within this genus and later Horwitz and Adams (2000) described an additional two species. Of the five species which are currently recognised three species (E. reducta, E. pseudoreducta and E. similis) form a species complex; the reducta complex. The work ofRiek and later Horwitz and Adams are the only two reviews of note dealing with this genus despite a publication by Crandall, Fetzner, Lawler, Kinnersley and Austin (1999) which suggests that Engaewa may be the sister …
A Study Of The Abundance, Distribution And Daily Activities Of The Australian Raven (Corvus Coronoides) In Urban Wetland Parks, Desiree L. Moon
A Study Of The Abundance, Distribution And Daily Activities Of The Australian Raven (Corvus Coronoides) In Urban Wetland Parks, Desiree L. Moon
Theses : Honours
Habitat destruction as a result of urbanisation has resulted in the population decline of some bird species. However, the Australian Raven (Corvus coronoides), has adapted well to the urban environment and is thriving. Although naturally occurring seasonal food sources are at times restricted in an urban setting, this adaptive species finds alternative food sources. As carrion-eaters this includes roadkill, as well as refuse discarded on the ground and into bins. Coupled with few natural predators, the species enjoys optimal conditions for breeding and survival. This biogeographical study investigated whether seasonal-influxes of populations of ravens cause problems at three urban wetland …
