The influence of light quality on seagrasses

Dredging alters the colour of light that reaches seagrass meadows. Previous research has focused on assessing how the reduction in light caused by dredge plumes influences seagrasses, but we’re yet to understand how the altered colour or light quality affects them. This research project aims to determine how changes in light quality influence the adult growth, flowering, seed germination and seedling survival of seagrasses. We will be using a range of field and aquarium based studies as part of a larger collaborative research project involving researchers from ECU, the University of Western Australia (UWA) and the Western Australia Marine Science Institution (WAMSI) as we aim to understand how dredging affects primary producers in marine ecosystems. The results from this project will be used to better inform managers regarding the time of year that is more appropriate to dredge in relation to the seagrass life cycle.
