Behavioural Ecology Of The Black-Flanked Rock-Wallaby (Petrogale Lateralis Lateralis): Refuge Importance In A Variable Environment, Craig Pentland Jan 2014

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 …


Taxonomy And Ecology Of The Western Australian Soldier Crab, Mictyris Occidentalis (Crustacea: Decapoda: Brachyura: Mictyridae), Joyleen Florence Unno Jan 2011

Taxonomy And Ecology Of The Western Australian Soldier Crab, Mictyris Occidentalis (Crustacea: Decapoda: Brachyura: Mictyridae), Joyleen Florence Unno

Theses: Doctorates and Masters

The taxonomy and autoecology of the Western Australian soldier crab, Mictyris occidentalis Unno, 2008 is presented including a new species description, a comprehensive ichnology, sampling methods, an extensive habitat description and a decadal population dynamics study. Such a wide ranging, holistic study has not been carried out for any mictyrid specious previously. In detail, a taxonomy component compares M. occidentalis with congeners, clearly establishing it as a separate species from M. longicarpus to which it was previously referred, and the issues affecting taxonomic classification in the Mictyris genus in general are discussed. A species identification key is provided for the …


Movement Patterns And Habitat Usage Of Shark Bay Dugongs, David K. Holley Jan 2006

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 …
