The Recovery Of Birds Through Farmland Revegetation In The Shire Of Goomalling, Western Australia, Rebecca Heath
The Recovery Of Birds Through Farmland Revegetation In The Shire Of Goomalling, Western Australia, Rebecca Heath
Theses : Honours
The birds of grazed paddocks, early revegetation (less than three years in age), three to seven year old revegetation, older revegetation (greater than seven years in age) and remnant vegetation were surveyed over the course of one year to determine whether revegetation recovers avian biodiversity in agricultural landscapes. Habitat features that were useful to the birds, and those that were missing from revegetation, were identified in order to broaden the knowledge base of faunal use of farmland revegetation, and aid in the devising of successful revegetation strategies. Notable differences in the abundance and composition of birds were found between the …
The Economic Value Of Tourism And Recreation In Forested Areas Of Western Australia, Rachel Goff
The Economic Value Of Tourism And Recreation In Forested Areas Of Western Australia, Rachel Goff
Theses: Doctorates and Masters
In recent years, natural area tourism has been presented as a more profitable, labour intensive and environmentally sound industry than the traditional extractive industries which have resulted in the depletion of primary resources in many countries (Burr, 1995). However, in order for economic returns from tourism to be maintained over a long period of time, investment in resources and infrastructure that support and encourage sustainable tourism and recreation activity in natural areas is required. The key to sustainability is maintaining the capital stock of resources (Garrod & Fyall, 1998; Russell, 2001). In a society driven by economics, resources are allocated …
Foraging Ecology And Habitat Selection Of The Western Yellow Robin (Eopsaltria Griseogularis) In A Wandoo Woodland, Western Australia : Conservation Ecology Of A Declining Species, Jarrad A. Cousin
Theses: Doctorates and Masters
This study examined the foraging ecology and habitat selection of the Western Yellow Robin in Wandoo Woodland at Dryandra Woodland, Western Australia. The foraging ecology component was comprised of an examination of foraging behaviour, perch-use selection and pounce-site characteristics. The habitat selection component was comprised of an examination of habitat characteristics of site occupancy and general nesting ecology. The implications of current management at Dryandra Woodland to the ecology of the Western Yellow Robin are discussed in reference to the findings of the present study. Ground-pouncing was the dominant foraging behaviour throughout all seasons, with dead branches of live subcanopy …
Do Size Differences Of Juvenile Snapper (Pagrus Auratus) In Two Regions Of Shark Bay, Western Australia, Reflect Different Environmental Conditions, Nadia Tapp
Theses: Doctorates and Masters
Aspects of the population biology of juvenile Pagrus auratus in the western gulf of Shark Bay, Western Australia, were investigated to explore the causes of an observed size difference between 0+ fish (first year of life) in the northern and southern regions of that gulf. Five trawl surveys were conducted in each region of the western gulf, from November 2000 to December 2001, to collect juvenile P. auratus. The 0+ fish from the northern region were found to be consistently greater in length by between 10 and 20mm LCF, than those in the southern region, thereby confirming those observed size …
The Effect Of Recreational Fishing On Targeted Fishes And Trophic Structure, In A Coral Reef Marine Park, Mark B. Westera
The Effect Of Recreational Fishing On Targeted Fishes And Trophic Structure, In A Coral Reef Marine Park, Mark B. Westera
Theses: Doctorates and Masters
Recreational line fishing is highly targeted at predatory fishes, making them vulnerable to overfishing. These same fishes play a role in trophic structure by regulating prey species. Despite increasing numbers of fishers, few studies have investigated the potential effects of recreational fishing on fish populations and subsequent trophic effects. This project investigated whether there were differences in fishes and benthos between unfished and recreationally fished areas, and whether the removal of targeted fishes influenced trophic structure. The study was conducted at the Ningaloo Marine Park, Western Australia, which had Sanctuary (no-take) and Recreation {recreationally fished) Zones. Data were collected from …
