Standardizing deoxygenation studies in coral biology
Abstract Deoxygenation, the global loss of biologically available oxygen (O2) from the world’s oceans, presents a pervasive and intensifying threat for reef-building corals that will require coordinated efforts to understand and manage. However, recent expansion of coral deoxygenation experimentation has produced methodological gaps, limiting collective knowledge generation.
Harnessing microalgae for finfish nutrition: advances in biotechnology and aquafeed development
Climate Change Cluster, University of Technology, Sydney, NSW, Australia New South Wales Department of Primary Industries, Port Stephens Fisheries Institute, Taylors Beach, NSW, Australia Finfish aquaculture is a key contributor to global seafood production, providing quality protein to consumers across the world, however, the search for regenerative, cost-effective and scalable raw materials continues. Alternatives to wild-caught fish have been explored extensively with limited success.
Algae | Scientific Reports
Algae are versatile photosynthetic organisms, with remarkable adaptability and metabolic properties that allow them to live in diverse and extreme habitats, as well as holding great potential for biotechnology. They play fundamental roles in their environments, including primary production, carbon fixation, and engineering their ecosystems.
Save the planet with green industries using algae
Loading metrics Open Access Perspective ? This is an uncorrected proof. We can use photosynthesis to capture carbon and make industries greener. Algae-driven carbon capture and manufacturing offer the potential for reducing CO2 emissions while also producing commodities such as bioplastics.

Chemotaxis increases metabolic exchanges between marine picophytoplankton and heterotrophic bacteria - Nature Microbiology
Abstract Behaviours such as chemotaxis can facilitate metabolic exchanges between phytoplankton and heterotrophic bacteria, which ultimately regulate oceanic productivity and biogeochemistry. However, numerically dominant picophytoplankton have been considered too small to be detected by chemotactic bacteria, implying that cell–cell interactions might not be possible between some of the most abundant organisms in the ocean.
Coral reef survival under accelerating ocean deoxygenation
Abstract Global warming and local eutrophication simultaneously lower oxygen (O2) saturation and increase biological O2 demands to cause deoxygenation. Tropical shallow waters, and their coral reefs, are particularly vulnerable to extreme low O2 (hypoxia) events. These events can drive mass mortality of reef biota; however, they currently remain unaccounted for when considering coral reef persistence under local environmental alterations and global climatic change.
Down to the bone: the role of overlooked endolithic microbiomes in reef coral health
Abstract Reef-building corals harbour an astonishing diversity of microorganisms, including endosymbiotic microalgae, bacteria, archaea, and fungi. The metabolic interactions within this symbiotic consortium are fundamental to the ecological success of corals and the unique productivity of coral reef ecosystems. Over the last two decades, scientific efforts have been primarily channelled into dissecting the symbioses occurring in coral tissues.
Forecasting global coral bleaching
Predicting coral bleaching is critical to better manage and preserve coral reefs from global warming. An impressive coordination of surveys across oceans now offers new metrics to help to predict coral bleaching events on a global scale. Fig. 1: Conceptual view of forecasting global coral bleaching.

Distinct Bacterial Communities Associated with the Coral Model Aiptasia in Aposymbiotic and Symbiotic States with Symbiodinium
Introduction Coral reefs are biodiversity hotspots of enormous ecological and economic importance. In these ecosystems, corals are the foundation species that build the calcium carbonate skeletons that give rise to the massive three-dimensional reef structures providing a habitat for millions of species (Reaka-Kudla et al., 1996) and economic activity worth around US$ 5.7 billion each year for Australia's Great Barrier Reef alone (Hoegh-Guldberg, 2015).
