Rates of ascidian mediated nitrogen cycling

Dirk Erler & Katie Kelly
Large solitary ascidians, like Herdmania grandis (Heller), can dominate the benthic substrates of subtropical and temperate reefs, however their influence on nitrogen cycling, particularly nitrous oxide (N2O) production, is unknown. Here we incubated individual H. grandis and compared fluxes of dissolved inorganic and gaseous nitrogen species to fluxes from reef sediments. Nitrous oxide production rates per individual ascidian (21 ± 8 nmol ind h-1) are the highest reported for any marine invertebrate. An individual ascidian...

Moving Corals RRAP

Marine Gouezo
This Project is co-led by SCU and CSIRO, with significant involvement of QUT. Coral restoration using larval ‘seeding’ aims to speed the return of coral cover, diversity and complexity to damaged reefs by increasing the number of available coral larvae for settlement and growth into new corals, particularly where reefs have low larval supply. The RRAP Moving Corals Sub-Program is a reef-based R&D project that aims to develop methods to cost-effectively produce billions of genetically...

Large-scale interventions may delay decline of the Great Barrier Reef

Scott Condie, Ken Anthony, Mark Baird, Roger Beeden, Daniel Harrison, Éva Plagányi, Russell Babcock, Cameron Fletcher, Rebecca Gorton, Alistair Hobday & David Westcott
On the iconic Great Barrier Reef (GBR) the cumulative impacts of tropical cyclones, marine heatwaves and regular outbreaks of coral-eating crown-of-thorns starfish (CoTS) have severely depleted coral cover. Climate change will further exacerbate this situation over the coming decades unless effective interventions are implemented. Evaluating the efficacy of alternative interventions in a complex system experiencing major cumulative impacts can only be achieved through a systems-modeling approach. We have evaluated combinations of interventions using a coral...
