Environmental Correlates And Associations Of Tuart (Eucalyptus Gomphocephala) Decline, Todd A. Edwards
Environmental Correlates And Associations Of Tuart (Eucalyptus Gomphocephala) Decline, Todd A. Edwards
Theses: Doctorates and Masters
Tuart (Eucalyptus gomphocephala DC.) is an ecologically and culturally important tree species that grows across a narrow 400 km long coastal belt, from the Sabrina River south of Perth, to Jurien Bay in the north. Unfortunately, Tuart is also a species under considerable threat due to clearing, lack of recruitment and canopy decline. Canopy decline is of particular concern, being increasingly reported throughout the Tuart distribution. Despite this, previous studies of Tuart have generally been limited to localised canopy decline events. This two-phased study firstly involved an assessment of Tuart canopy condition at 46 sites across the species distribution. At …
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 …
