The Near-Shore, Soft-Substrate Bivalves Of The Swan Estuary: An Assessment Of Their Use As Biological Indicators, Graham Bailey
The Near-Shore, Soft-Substrate Bivalves Of The Swan Estuary: An Assessment Of Their Use As Biological Indicators, Graham Bailey
Theses : Honours
The soft-substrate bivalves of the Swan Estuary were evaluated for their suitability as biological indicators. The major requirement of a biological indicator is that a response to changing conditions can be shown. Demonstrating that bivalve community and populations respond to changing environmental conditions within The Estuary would fulfill this criteria. To make this assessment the study conducted a quantitative sampling program which established the current structure of the near-shore soft-substrate bivalve community and this was compared with the community established in 1973-74. To evaluate the predictive potential of bivalve structure as an indicator, major environmental conditions in the Estuary were …

Application Of Time Series Models To Sets Of Environmental Data, Saarah Ahmed Farag
Theses : Honours
In environmental studies, many programs have been implemented for the purpose of examining the influence of factors on the natural environment from various sources. In the past, predictions have been obtained from a simple regression model of the data from these programs to aid in deciding whether an intervention is required in the program or policy. However, most environmental time series involve correlated dependent variables which makes it difficult to apply conventional regression analysis. This thesis compares the application of the class of transfer function models, where high correlation between dependent variables is allowed, to that of conventional regression analysis. …
