An Ecological Characterisation Of A Shallow Seasonal Claypan Wetland, Southwestern Australia, Nakisa Shahrestani

Theses: Doctorates and Masters

Perched, seasonal claypans of southwestern Australia are poorly understood in terms of their ecological character, such as relationship between hydrology and their biota. An example is Little Darkin Swamp, located on the Darling Plateau in southwestern Australia. The overall aim of this thesis was to describe its ecological character, to understand what drives this claypan system and how its ephemeral nature affects wetland processes and functions.

This study first comprised a detailed characterisation of the wetland’s attributes, following the geomorphic-hydrological approach proposed by Semeniuk and Semeniuk (2011). This revealed that its hydrology is highly dependent on rainfall, that it is …
