Summary: Detritus, non-living organic material, is the major carbon pathway in estuaries, promoting biodiversity and contributing to the sustainability of fisheries and vital ecosystem services. Since industrialisation, detrital-source biodiversity has been changing in estuaries because of human impacts to aquatic macrophytes (e.g. global seagrass declines) and aquatic plant invasions. We propose to determine for first time the role of detrital biodiversity in estuaries and forecast impacts of human-induced changes to detrital composition in estuaries in Australia and in the USA. Outcomes of our rigorous field experiments can be used to improve decision support systems and management policies that will ensure sustainability of estuarine ecosystems.'',
