| Survey/Project Name: | MOUND SPRING INVERTEBRATES - MURPHY/GUZIK/KING |
| Abstract: | Data collected as part of work for following projects: 1a. Comparative phylogeography of mound springs-invertebrates: identifying genetically divergent populations for conservation and management 1b. Evolution of the unique fauna of the Great Artesian Basin mound springs: the impact of aridification and climate change. SUMMARY: The unique invertebrate communities of the mound springs of the Great Artesian Basin, in the Far North region of South Australia, are under potential threat. Using molecular techniques we will examine and compare the population genetics of invertebrate species that reflect the diverse communities within these springs. By comparing the patterns of genetic diversity from co-distributed, biologically diverse groups, we will identify geographic areas within which whole communities have undergone significant periods of independent evolution. This will identify regions of particular significance for conserving maximum genetic diversity across entire communities, aiding the development of plans for their management and conservation. [September 2007 to August 2009] 2. Population genetics of desert spring invertebrates: SUMMARY: Recent studies have identified numerous new species in South Australian mound springs, this study will determine how these aquatic species move between springs that are separated by desert.

| Survey Type: | Invertebrates Only |
| Study Area Description: | GAB Mound Springs |
| Objectives | |||
| Vegetation: | *** No vegetation survey objectives recorded | ||
| Fauna: | 1a)To characterise the genetic diversity of five key aquatic and terrestrial mound spring invertebrates across different geographical scales (eg within and between spring groups). To ascertain how spring size and degree of isolation affect genetic composition and demography To ascertain how genetic composition and demography have changed over time To determine whether specific, apparently widespread taxa represent cryptic species complexes To compare and contrast the patterns of diversity among the different study organisms and identify springs/regions sharing common patterns of diversity or endemicity 1b) To investigate the evolutionary radiations of the fauna associated with the GAB mound springs using molecular methods and determine the impacts of historical climate change on this unique faunal assemblage. 2)Undertake population genetic studies of amphipod, isopod and ostracod crustaceans inhabiting the mound springs along the western edge of Lake Eyre. The objective is to determine how the different species disperse between springs that do not share a direct aquatic connection. This study continues work from previous research in this area undertaken whilst I was a researcher at the University of Adelaide. | ||
