dc.description.abstractThe floodplain wetlands of the Murray-Darling Basin are subject to a range of human impacts, such as water diversion and land use changes, in addition to the effects of drought and climate change (Kingsford, 2000). Despite prolonged modification of natural water regimes, these wetlands provide essential habitat for both terrestrial and aquatic biota (Mazumder et al, 2011 In recent years, ANSTO and NSW Office of Environment and Heritage have sought to describe the effects of altered flow regime upon ecological function within the Murray-Darling Basin using stable isotope techniques. Measuring the relative abundance of carbon and nitrogen stable isotope ratios (513C and 515 N) is a useful technique in food web research, as it provides the basis for modelling trophic connectivity and the movement of energy through a system (Iles et al, 2010). From 2006-201 1, research has focused on the Macquarie Marshes, Gwydir Wetlands and Lower Murrumbidgee, where extensive field sampling has resulted in a large body of work incorporating 613C and 515 N stable isotope analysis to investigate spatial and temporal ecosystem responses to flow regime. Here we present a summary of the major findings of the work from this period, which produced four peer reviewed journal publications, a number of book chapters and several government reports. The work has provided essential insights into the impacts of flow regulation upon trophic linkages, nutrient transfer, and competition between native and introduced species. en_AU
