Trophic Implications Of Light Reductions For Amphibolis Griffithii Seagrass Fauna, Adam Gartner
Trophic Implications Of Light Reductions For Amphibolis Griffithii Seagrass Fauna, Adam Gartner
Theses: Doctorates and Masters
The ongoing threat of seagrass loss from reduced light availability, coupled with our lack of knowledge of associated trophic responses has motivated this characterization of the flow-on effects of light reductions to Amphibolis griffithii seagrass fauna. Recently, field manipulations of varying light reductions, induced disturbances in a A. griffithii seagrass meadow that have been shown to effect potential food resources and the structural complexity of seagrass habitats for macroinvertebrates. This offered the opportunity to assess the flow-on effects to seagrass for fauna, a topic that has seldom been examined. This study investigated the effects of different light reduction intensity (high: …
In Vitro Propagation Of Some Western Australian Seagrasses, Julia Wilson
In Vitro Propagation Of Some Western Australian Seagrasses, Julia Wilson
Theses: Doctorates and Masters
The development of a successful protocol for micropropagating seagrass provides a valuable tool for seagrass-restoration programs and a facility to study their biology (especially their physiology). This work reports on some of the culture requirements of some seagrasses that are commonly found in Western Australia: Posidonia coriacea, P. sinuosa, P. australis and Halophila ovalis. The protocol developed for H. ovalis allows very rapid multiplication and sustainable growth of cultures while the protocol developed for Posidonia requires further development. The culture of Posidonia cariacea proved to be problematic however experimental media that provided insights into its culture conditions. The carbohydrate source …
Changes To The Distribution Of Posidonia Seagrass Communities Of James Point, In Response To The Development Of Cockburn Sound, Western Australia, Anthony Muscara
Changes To The Distribution Of Posidonia Seagrass Communities Of James Point, In Response To The Development Of Cockburn Sound, Western Australia, Anthony Muscara
Theses: Doctorates and Masters
Australia’s oceans provide many economic and environmental benefits both nationally and regionally, and are of particular social, recreational and cultural importance. Western Australia's most intensively used marine embayment is Cockburn Sound, is Cockburn Sound, it supports one of the most extensive Posidoni seagrass communities in Western Australia. The protected coastal waters off the southern metropolitan coastline of Perth arc utilised intensively for industrial, commercial and recreational purposes. Over the past 50 years, wastes have been routinely discharged into Cockburn Sound causing extensive phytoplankton and epiphyte blooms, particularly during the 1960's and 1970's. The development of industrial and naval facilities and …
