Keynote 1: Climate change transforms coral reef assemblages

Heat stress due to global warming triggered global-scale bleaching of corals in 1998, 2010 and 2015/2016, and is rapidly emerging as the most important contemporary threat to the world’s coral reefs. We recorded mass-mortalities of corals following the record-breaking marine heatwave in the summer of 2016 that have transformed reef assemblages in the northern and central Great Barrier Reef, the world’s largest coral reef system. The severity of bleaching, mortality and of the shift in taxonomic composition of corals over a distance of close to 1,000km, were all directly related to regional patterns of heat exposure. The depletion of corals has substantially reduced ecological functions. Furthermore, the pre-bleaching coral assemblages are unlikely to reassemble in coming decades because of the increasing frequency of climate-driven mortality events, leading to the emergence of novel, depauperate assemblages. These ecological responses are a harbinger of further radical shifts in the species composition of all marine ecosystems, especially if global action on climate fails to achieve a +1.5–2 °C global average target.

Keynote 2: On the use of stable isotopes to elucidate ecosystem functioning and end-to-end food webs

Biogeochemistry and ecosystem ecology aim to advance our understanding of material flows within, and the functioning of, ecosystems. The (bio)geochemists provide quantitative rigor and tools for tracing flows, while ecologists emphasize the need to embrace biodiversity.
The link between organism identity/activity and biogeochemical processes is still poorly known. I will present some examples how organic geochemical tools, biogeochemical process studies and whole ecosystem isotope labeling studies can be combined to elucidate the flow of carbon and nitrogen through ecosystems (e.g., cold-water corals, sponges and coastal sediments).

Keynote 3: Diversity in virus communities and the rare virosphere

The diversity within virus communities can be interrogated by metagenomic analysis or by deep-sequencing of amplicons. Results from deep-sequencing of virus marker genes that represent specific viral groups, reveal that within related groups of DNA or RNA viruses, most genotypes are rare. Moreover, the composition of these communities are temporally and spatially dynamic. Sequence differences in marker genes also reflect broader differences in gene content, and thus imply likely functional differences among phylogenetic groups that are defined by sequence differences within marker genes. Ultimately, it is the combination of metagenomic and amplicon-based approaches that will give us the deepest insights into the composition and function of ocean-virus communities.

Keynote 4: Building the ocean observing and monitoring systems to support good decisions by marine industries and governments

“You can’t manage what you don’t measure”: Designing and building ocean observing and monitoring systems to support robust ocean health assessments and improve the ability (and chances) of marine industries and governments making good decisions on sustainable development.
John Gunn

In the Anthropocene, a suite of pressures on our oceans are threatening species, ecosystems, livelihoods and indeed some of the planet’s core life support systems. For the last few decades scientists have been banging the drum, trying to get the message across to politicians, policy makers and the community that the impacts of these pressures, now and in the future, will cause massive harm to our global community. Although “climate change”, overfishing, pollution and even noise are acknowledged as pressures by many, arguably the science community has had mixed success in a. getting the message across that mitigation and adaptation are critical and immediate needs, and b. driving the required responses. Indeed, in some countries there is growing push back on what is sold as science “doom and gloom” messages.
Having worked at the interface between science, policy and community for many years, I think one of the impediments to getting our messages across is the lack of robust and publically available data sets, collected at time and space scales that allow us to talk with authority about historical trends and current state, and provide a basis for projections of future state.
The climate science community awoke to this issue over thirty years ago and through the World Meteorological Organization and UNESCO’s Intergovernmental Oceanographic Commission they developed the Global Climate Observing System (GCOS) and associated Global Ocean Observing System (GOOS). These two global collaborations have driven the collection of data at space and time scales required to develop and improve Global Climate Models. They have precipitated massive innovation in observing technologies (satellite sensors/systems; robotics), and driven a culture of sharing data, models, and coordinated assessments (IPCC AR etc).
The ocean biogeochemistry and biology/ecology communities have lagged behind the climate scientists, and as a result global assessments of these elements of the ocean system range from patchy to grossly inadequate. Over the last five years, GOOS and GCOS have worked hard to extend their ocean observing systems for physics to include biogeochemistry and biology. I will provide an overview of the progress that has been made, and use a new integrated monitoring program that is being developed for the Great Barrier Reef as a case study of how we might finally start to develop comprehensive and robust observations and data sets for ocean ecosystems.

Keynote 5: Ensuring a future for corals through assisted evolution

Coral reefs are in rapid decline due to a multitude of anthropogenic activities causing ocean acidification, mechanical damage, declining water quality and climate change. Climate models based on unmitigated greenhouse gas emissions predict temperature anomalies causing severe coral bleaching will occur annually on 99% of the world’s coral reefs within this century. Such severe coral bleaching events lead to extensive coral mortality. Human interventions that increase coral tolerance to thermal and other stresses, and assist in coral reef recovery are thus urgently required in order to ensure coral reef persistence into the future. Assisted evolution (AE) is the acceleration of naturally occurring evolutionary processes to enhance certain traits, and includes selective breeding and preconditioning of coral, directed evolution of coral photosymbionts (Symbiodinium spp.), and manipulation of the coral-associated prokaryotic communities (probiotics). Our proof-of-concept work shows exciting early results, with evidence for rapid temperature and herbicide adaptation in Symbiodinium through directed evolution, the outperformance of purebred genotypes by recombinant genotypes (interspecific hybrids), and a change in the coral-associated prokaryote community composition following inoculation of larvae with specific microbiomes. I will present some of these results and discuss how our findings may be applied to coral reef restoration initiatives. Expanding from our AE work, we have recently begun to explore synthetic biology approaches as these may achieve our goals (i.e., coral stock with increased stress tolerance) faster. I will briefly discuss our progress and near-future plans in this field.
