Despite the existence of a large body of agricultural research literature, very few studies have been undertaken which specifically address the effects of agricultural manipulations upon biodiversity. In this study aquatic faunal communities were compared within Australian commercial rice fields cultivated under three different management regimes : conventional-aerial (agrochemicals applied, aerially sown), conventional-sod (agrochemicals applied, directly sown) and organic-sod (agrochemical-free, directly sown). These comparisons were undertaken using a combination of community assessment approaches including morphospecies richness, abundance and diversity, pollution sensitivity scores and community composition. Additionally, food web studies were undertaken using stable isotope analysis to investigate functional differences in trophic structure and food resource utilisation across management regimes.
