NEW: Nature Climate Change paper
Ocean Predators Affect Carbon Sequestration The loss of top level ocean predators, such as sharks, can have far-reaching consequences for our ability to offset climate change impacts. The abundance of ocean predators can affect carbon capture, accumulation and preservation in vegetated coastal habitats such as mangroves, saltmarsh and seagrass. Intact predator populations are critical to maintaining and even growing reserves of ocean carbon. Policy and management need to be improved to reflect these realities. · Coastal wetland habitats occupy <1% of the seafloor · Yet sequester > half the ocean’s stored carbon, ‘blue carbon’ · They store carbon 30-50 times faster than tropical rainforest · And can store for very long times (100s to 1000s of years) · They store another $5.4 billion worth of carbon every year · But we can lose a lot of that by mis-managing ocean predators! |

Australian Research Council: Discovery Project
We have a new Discovery Project funded by the Australian Research Council investigating how the resilience of marine ecosystems is influenced by connectivity among ecosystem components. The project tests ecological theories about the response of ecosystems to environmental disturbance and leads to practical outcomes that will influence natural resource management. The project is led by Prof. Rod Connolly in collaboration with Prof. Thomas Schlacher (University of the Sunshine Coast). |

New project Solomon Islands - science of sustainable fishing
Dr Chantal Huijber leads a new project using stable isotope analysis to trace the dependence of of fisheries species on coastal habitats such as seagrass and mangroves. |
Paul Maxwell awarded PhD for marine resilience research
Paul has graduated with his PhD for work with Rod and Kylie Pitt entitled "Ecological resilience theory: application and testing in seagrass ecosystems". Paul used a combination of underwater surveys and mathematical modelling to identify critical feedback loops and measure resilience in seagrass meadows exposed to severe environmental disturbance.
See his latest paper: Phenotypic plasticity promotes persistence following severe events: physiological and morphological responses of seagrass to flooding (2014) Maxwell PS, Pitt KA, Burfeind DD, Olds AD, Babcock RC, Connolly RM. Journal of Ecology.

Watch Rod's talk about resilience at TEDx
Rod's TEDx talk is about resilience in marine ecosystems, with examples from other disciplines. He highlights student Paul Maxwell's focus on feedback loops as the key to understanding and measuring resilience.

Catalyst episode on the effects of the Moreton Bay floods
Rod and colleagues recently showcased their work on a national segment of ABC TV program Catalyst. They focussed on their research into the effects and outcomes of a major flood in southeast Queensland and the response of seagrass and corals to massive sediment input.
The show can be watched on the ABC Catalyst site.

Sample acidification alters stable isotope ratios of sulfur in aquatic plants and animals
This feature article by Connolly and Schlacher in Marine Ecology Progress Series (2013) shows that acidification of samples prior to sulfur isotope analysis results in invalid ratios and should not be used. |

Water Sciences collaboration (CRN)
Rod works with a team of prominent ecologists in the federally-funded Collaborative Research Network led by Prof. Thomas Schlacher, University of Sunshine Coast.
Their projects include: 1. carbon transfer from ocean to land, in Australia and the Pacific islands, 2. marine reserves and food security in coral reef seascapes.
