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 …
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 …
