A Functional Group Approach To Detecting Shifts In Macroalgal Communities Along A Disturbance Gradient, J. C. Phillips
A Functional Group Approach To Detecting Shifts In Macroalgal Communities Along A Disturbance Gradient, J. C. Phillips
Theses : Honours
A recently proposed hypothesis argued that morphologically and functionally similar macroalgae could be grouped to study the structure of macroalgal communities. It was argued that these functional groups can be used to predict changes to community composition that result from disturbance. This study examined whether the functional group model held in detecting changes in macroalgal community structure within one bioregion, by applying it to a habitat exposed to different levels of physical disturbance associated with wave exposure. Results obtained using a functional group approach were compared to those obtained using a species level approach. Three parallel reef lines in Marmion …

Temporal And Spatial Patterns In Water Chemistry, Phytoplankton Biomass And Microcrustacea In Lake Joondalup And Beenyup Swamp, Western Australia, Kimberley Upton
Theses : Honours
Lake Joondalup is one of the largest remaining permanent lakes of the Swan Coastal Plain. Despite increasing urbanisation, it supports highly diverse terrestrial and riparian communities, and an abundant and diverse aquatic fauna. However, like other wetlands of the Swan Coastal Plain, Lake Joondalup is increasingly threatened by eutrophication and degradation. The aims of this study were to describe the patterns in selected physical, chemical parameters, microcrustacean abundance and biomass of Daphnia carinata in Beenyup Swamp and the adjacent sections of Lake Joondalup; to identify the likely factors determining the patterns of phytoplankton biomass in these wetlands; and to suggest …
