The Hillarys Transect (1): Seasonal And Coss-Shelf Variability Of Physical And Chemical Water Properties Off Perth, Western Australia, 1996-98, Alan F. Pearce, M J. Lynch, Christine E. Hanson Apr 2006

The Hillarys Transect (1): Seasonal And Coss-Shelf Variability Of Physical And Chemical Water Properties Off Perth, Western Australia, 1996-98, Alan F. Pearce, M J. Lynch, Christine E. Hanson

School of Natural Sciences Publications

A 27-month study of the water properties across the continental shelf off Perth, Western Australia (the "Hillarys Transect") has provided the first systematic inter-disciplinary climatology of the physical, chemical, optical and biological cycles across the shelf. This paper describes the main features of the seasonal and cross-shelf variability of the physical oceanography and chemistry, while companion papers discuss some of the links between the biology and physics of the region

The Ecology And Behaviour Of Varanus Mertensi (Reptilia: Varanidae), Phillip J. Mayes Jan 2006

The Ecology And Behaviour Of Varanus Mertensi (Reptilia: Varanidae), Phillip J. Mayes

Theses: Doctorates and Masters

This study examines numerous aspects of the ecology and behaviour of Merten's Water Monitor, Varanus mertensi (Reptilia: Varanidae) including; daily behaviour, diet, foraging behaviour, reproductive seasonality and daily and long-term movements. Findings from over two years of field study of V. mertensi found in waterbodies of both the Ord River Irrigation Scheme and surrounding East Kimberley/Victoria River Downs bioregion of Western Australia are presented. This study simultaneously broadens our understanding of the family Varanidae and provides insight into the life of a semi-aquatic faunal species found in waterbodies of the Ord River Irrigation Scheme.


The Influence Of Seabird-Derived Nutrients On Island Ecosystems In The Oligotrophic Marine Waters Of South-Western Australia, Sofie A. Harrison Jan 2006

The Influence Of Seabird-Derived Nutrients On Island Ecosystems In The Oligotrophic Marine Waters Of South-Western Australia, Sofie A. Harrison

Theses: Doctorates and Masters

Nutrient inputs from productive marine environments have been shown to directly and indirectly subsidise primary producers and consumers in terrestrial ecosystems (e.g. Polis and Hurd 1995; 1996; Anderson and Polis 1998; 1999). But does this theory hold true on islands surrounded by oligotrophic waters, which account for a significant proportion of the marine environment? The aim of the present study was to examine the applicability of the spatial subsidisation hypotheses proposed by Polis and his co-authors to an oligotrophic system in south-western region of Western Australia. These aims were achieved by comparing soil and plant nutrients, and the nitrogen stable …


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 …


Reintroduction Ecology Of Mala (Lagorchestes Hirsutus) And Merrnine (Lagostrophus Fasciatus) At Shark Bay, Western Australia, Blair Hardman Jan 2006

Reintroduction Ecology Of Mala (Lagorchestes Hirsutus) And Merrnine (Lagostrophus Fasciatus) At Shark Bay, Western Australia, Blair Hardman

Theses: Doctorates and Masters

The transfer of threatened animals from one location to another in order to benefit the species is a technique frequently used by animal conservation managers. However, very few of these relocations have experimentally assessed the relative merits and disadvantages of commonly used release techniques. Two species of hare-wallaby, mala (Lagorchestes hirsutus) and merrnine (Lagostrophus fasciatus), were reintroduced in August 2001 onto Peron Peninsula in Western Australia. These threatened species were reintroduced using two release strategies (soft versus hard release), and their subsequent movements and body condition were monitored using radio-telemetry and trapping.
