Nocturnal Roost Tree, Roost Site And Landscape Characteristics Of Carnaby's Black-Cockatoo (Calyptorynchus Latirostris) On The Swan Coastal Plain, Candice Le Roux
Nocturnal Roost Tree, Roost Site And Landscape Characteristics Of Carnaby's Black-Cockatoo (Calyptorynchus Latirostris) On The Swan Coastal Plain, Candice Le Roux
Theses: Doctorates and Masters
There is limited information on communal roosting in parrot species of Western Australia and other parts of the world. Carnaby’s Black-Cockatoo is an endangered species that forms large nocturnal communal roosts, and for this reason they are an ideal model species to test the characteristics or factors that are associated with roost sites. Known roost sites distributed across the Swan Coastal Plain were identified and selected through the Great Cocky Count project. A minimum of five and maximum of ten individual trees were assessed at 11 roost sites with an overall total of 95 roost trees sampled. I determined the …
Behavioural Ecology Of The Black-Flanked Rock-Wallaby (Petrogale Lateralis Lateralis): Refuge Importance In A Variable Environment, Craig Pentland
Behavioural Ecology Of The Black-Flanked Rock-Wallaby (Petrogale Lateralis Lateralis): Refuge Importance In A Variable Environment, Craig Pentland
Theses: Doctorates and Masters
The black-flanked rock-wallaby (Petrogale lateralis lateralis) has suffered a significant decline in its distribution in Western Australia. This has been attributed to introduced predators (predominantly the red fox) and herbivores, fire, and habitat destruction due to clearing. Although since 2001 the Department of Environment and Conservation (DEC) had begun to reintroduce this species back into its former range, little was known of the behavioural ecology of this species. Fox control in the 1980s and 1990s resulted in population increases of rock-wallabies on several reserves in the central wheatbelt of WA. However, recently these populations have rapidly declined despite continuing fox …
Systematics And Biogeography Of The Australian Burrowing Freshwater Crayfish Genus Engaewa Riekk (Decapoda: Parastacidae), Quinton Burnham
Systematics And Biogeography Of The Australian Burrowing Freshwater Crayfish Genus Engaewa Riekk (Decapoda: Parastacidae), Quinton Burnham
Theses: Doctorates and Masters
The overall aim of this study was to explore the systematics and biogeographic patterns of the freshwater crayfish genus Engaewa Riek, a strongly burrowing freshwater crayfish restricted to the coastal corner of south-western Australia (SWA). The genus Engaewa is a Gondwanan relict with great potential as a marker of historical processes, due to its high habitat specificity and low dispersal ability. This study comprises an extensive taxonomic and phylogenetic revision of the genus Engaewa (using both molecular and morphological data), a detailed study of its distribution and uses the knowledge gained to explore biogeographic patterns in the biodiversity hotspot of …
Geostatistical Spatiotemporal Modelling With Application To The Western King Prawn Of The Shark Bay Managed Prawn Fishery, Ainslie M. Denham
Geostatistical Spatiotemporal Modelling With Application To The Western King Prawn Of The Shark Bay Managed Prawn Fishery, Ainslie M. Denham
Theses: Doctorates and Masters
Geostatistical methodology has been employed in the modelling of spatiotemporal data from various scientific fields by viewing the data as realisations of space-time random functions. Traditional geostatistics aims to model the spatial variability of a process so, in order to incorporate a time dimension into a geostatistical model, the fundamental differences between the space and time dimensions must be acknowledged and addressed. The main conceptual viewpoint of geostatistical spatiotemporal modelling identified within the literature views the process as a single random function model utilising a joint space-time covariance function to model the spatiotemporal continuity. Geostatistical space-time modelling has been primarily …
Distribution Patterns And Habitat Use Of Black Cockatoos (Calyptorhynchus Spp.) In Modified Landscapes In The South-West Of Western Australia, Marieke S. Weerheim
Distribution Patterns And Habitat Use Of Black Cockatoos (Calyptorhynchus Spp.) In Modified Landscapes In The South-West Of Western Australia, Marieke S. Weerheim
Theses: Doctorates and Masters
Conservation planning for animal species inhabiting modified landscapes requires understanding of where animals occur and how they utilise both natural and modified habitats. In this study the distribution and foraging behaviour of the forest red-tailed cockatoo (Calyptorhynchus banksii naso), Baudin’s cockatoo (C. baudinii) and Carnaby’s cockatoo (C. latirostris) was investigated in three study areas which each contained a different combination of modified habitats. Pickering Brook contained native forest and orchards, Wungong contained a mosaic of native forest and revegetation, while Karnet contained primarily native forest and paddocks. The relationship between cockatoo distribution and land use types was examined by constructing …
Comparison Of Three Survey Methods Applied To The Recreational Rock Lobster Fishery Of Western Australia., Tara Baharthah
Comparison Of Three Survey Methods Applied To The Recreational Rock Lobster Fishery Of Western Australia., Tara Baharthah
Theses: Doctorates and Masters
A mail survey of recreational rock lobster licence holders has been conducted annually since 1986. The results from this survey have been used in the management of the recreational rock lobster fishery in Western Australia. Mail surveys are susceptible to non-response and recall bias. The key to determining useful estimates of fishing catch and effort is to minimise both biases. Telephone recall surveys, with high response rates, effectively eliminate nonresponse bias. However, they still suffer from recall bias when the recall period is greater than two months. Telephone diary surveys are free of non-response bias and recall bias and provide …
Movement Patterns And Habitat Usage Of Shark Bay Dugongs, David K. Holley
Movement Patterns And Habitat Usage Of Shark Bay Dugongs, David K. Holley
Theses: Doctorates and Masters
In order to define small and large scale spatial and temporal individual movement patterns of dugongs (Dugong dugon) within the Shark Bay World Heritage Property (SBWHP) a total of 19 dugongs were fitted with remote location recording and transmitting devices. Combined locations from all units totalled over 10,000 locations. This spatial and temporal data was used to define movement patterns of dugongs within Shark Bay as well as areas of high use deemed to be indicative of foraging activity. Platform Transmitting Terminals (PTT?s) using the ARGOS location collection system tracked animals over large temporal scales with 4 animals tracked up …
Investigation Of The Replacement Of Margaret River Hairy Marron Cherax Tenuimanus (Smith) By Smooth Marron C. Cainii Austin, John J. Bunn
Investigation Of The Replacement Of Margaret River Hairy Marron Cherax Tenuimanus (Smith) By Smooth Marron C. Cainii Austin, John J. Bunn
Theses: Doctorates and Masters
The Margaret River hairy marron, Cherax tenuimanus (Smith, 1912) (Decapoda: Parastacidae) is critically endangered due to the introduction of the widespread marron, C. cainii Austin, 2002. This project investigates the rapid replacement of C. tenuimanus with studies important to its conservation. The ability to identify correctly in the field C. tenuimanuss, C. cainii and hybrids was investigated by linking morphology and marker allozyme loci. C. tenuimanus was readily identified in the field and errors were conservative; no genetically identified hybrids or C. cainii were field identified as C. tenuimauus during tissue samples collection. A prototype field identification guide has been …
The Role Of Farm Dams As Refugia For Aquatic Invertebrates In A Salinised Landscape, South Western Australia, Jean-Michel Benier
The Role Of Farm Dams As Refugia For Aquatic Invertebrates In A Salinised Landscape, South Western Australia, Jean-Michel Benier
Theses: Doctorates and Masters
In a salinised landscape farm dams may represent the last truly freshwater surface resource, and therefore provide refuge habitats for the biota of wetlands affected by increasing salinity. One wetland threatened by increased salinity in south-west Western Australia is Lake Toolibin. It is listed as a Wetland of International Importance under the Ramsar Convention in recognition of its high conservation value, and remediation actions to halt (and possibly reverse) further increases in salinity are being undertaken at this wetland. Farm dams act as aquatic refugia if they convey resistance and/or resilience to the biotic communities of a disturbed habitat. This …
Terrestrial Isopods (Crustacea: Oniscidea) And Biogeographical Patterns From South-Western Australia, Simon L. Judd
Terrestrial Isopods (Crustacea: Oniscidea) And Biogeographical Patterns From South-Western Australia, Simon L. Judd
Theses: Doctorates and Masters
This thesis examines terrestrial isopod (Crustacea: Oniscidea) diversity and biogeography from south-western Australia, a region already recognised for the exceptional high biodiversity and concentrations of endemic species. A taxonomic investigation of isopods in the Western Australian Museum and material collected systematically as part of this study revealed seventy taxa, sixty of which were considered native species. The thesis provides a comprehensive review of regional taxonomic history and includes a key, complete with a set of forty characters states and taxa, illustrated by a number of photographic plates that are designed for use by specialists and non-specialists alike. Prior to this …
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 Reproductive Biology And Temporal Distribution Of A Great Egret And Nankeen Night Heron Colony At The Perth Zoo, Robyn Phillimore
The Reproductive Biology And Temporal Distribution Of A Great Egret And Nankeen Night Heron Colony At The Perth Zoo, Robyn Phillimore
Theses: Doctorates and Masters
A colony of Great Egrets (Ardea alba) and Nankeen Night Herons (Nycticorax caledonicus) has existed at the Perth Zoo in Metropolitan Perth for over 25 years. The colony is particularly significant for the conservation and management of Great Egrets in Western Australia as it is the only colony located in the Metropolitan area. Baseline information of their breeding biology was needed to facilitate the development of management guidelines for the zoo colony. Foraging behaviour was used to highlight specific adaptations in hunting strategies and diet. However, it was not possible to observe foraging Nankeen Night Herons as they forage at …
Landscape Differences In The Ecology Of The Rufous Treecreeper Climacteris Rufa, Gary W. Luck
Landscape Differences In The Ecology Of The Rufous Treecreeper Climacteris Rufa, Gary W. Luck
Theses: Doctorates and Masters
Anthropogenic habitat modification is a significant threat to the conservation or global biodiversity. The fragmentation and alteration of woodland habitat has resulted in the substantial decline of many woodland bird species in the agricultural regions of southern Australia. The Rufous Treecreeper Climacteris rufaa, a once common woodland resident, has declined in abundance in the wheatbelt of Western Australia and appears to be sensitive to habitat fragmentation. The reasons for this are unclear because our knowledge of the species and the threats posed by fragmentation arc limited. In this study, I compared the social organisation, habitat selection, reproductive success, dispersal and …
Influence Of Adjacent Seagrass On The Fish Assemblages Off Sandy Beaches, Matthew A. Vanderklift
Influence Of Adjacent Seagrass On The Fish Assemblages Off Sandy Beaches, Matthew A. Vanderklift
Theses: Doctorates and Masters
As we attempt to maintain marine biodiversity mainly by focussing on habitats, we need to understand how marine biodiversity is affected by seagrass loss. Although managers and researchers widely acknowledge that habitat loss results in changes to marine biodiversity, quantitative knowledge of these changes is generally poor. In this study, fish assemblages (as one component of the biodiversity of sandy beaches) were examined in Cockburn Sound, Western Australia, to assess patterns that may be related to presence or absence of adjacent seagrass beds, If consistent patterns are evident, they may enable predictions regarding the effects of seagrass loss on the …
