Marine biology is the study of life in the oceans and brackish waters, which ranges from archaea and bacteria to marine mammals, and includes organisms such as corals that affect the shape of the seafloor. This may also include human modifications to ocean biology, such as fisheries or the effects of overfishing.

Competing effects of wind and buoyancy forcing on ocean oxygen trends in recent decades
Ocean deoxygenation since the late 1960s has been partially mitigated by wind-driven oxygenation, particularly in the Southern Ocean. The predicted slowdown in wind intensification may therefore accelerate ocean deoxygenation in the coming decades.

Reduced and smaller phytoplankton during marine heatwaves in eastern boundary upwelling systems
Longer and more intense marine heatwaves are associated with a dominance of smaller plankton species and lower overall biomass, according to an analysis of ocean color satellite data and distribution modeling.

Coral photosymbiosis on Mid-Devonian reefs
Nitrogen isotope evidence of Mid-Devonian photosymbiotic associations in certain types of corals suggests thatautotrophic and heterotrophic corals co-existed on extinct reefs, as today, but in warmer oceans, indicating the current warming rate, not temperature, is causing coral bleaching.

Coral reefs deserve evidence-based management not heroic interference
Climate impacts are triggering a host of novel bio- and geoengineering interventions to save coral reefs. This Comment challenges heroic scientific assumptions and advocates for a more systemic, evidence-based approach to caring for coral reefs.

Mixed management boosts reef shark abundance
A global survey using baited cameras on coral reefs demonstrates a near twofold increase in the relative abundance of reef sharks in marine protected areas that are also embedded within areas of effective fisheries management. However, such conservation benefits were not evident for wide-ranging sharks or rays found on the reef.

Shining light on dinoflagellate photosystem I
Dinoflagellates are ecologically important and essential to corals and other cnidarians as phytosymbionts, but their photosystems had been underexplored. Recently, photosystem I (PSI) of dinoflagellate Symbiodinium sp. was structurally characterized using cryo-Electron Microscopy (cryo-EM). These analyses revealed a distinct organization of the PSI supercomplex, including two previously unidentified subunits, PsaT and PsaU, and shed light on interactions between light harvesting antenna proteins and the PSI core. These results have implications with respect to the evolution of dinoflagellates and their association with cnidarians.

Restoration as a meaningful aid to ecological recovery of coral reefs
Restoration supports the recovery of ecological attributes such as cover, complexity, and diversity to slow the areal decline of natural ecosystems. Restoration activity is intensifying worldwide to combat persistent stressors that are driving global declines to the extent and resilience of coral reefs. However, restoration is disputed as a meaningful aid to reef ecological recovery, often as an expensive distraction to addressing the root causes of reef loss. We contend this dispute partly stems from inferences drawn from small-scale experimental restoration outcomes amplified by misconceptions around cost-based reasoning. Alongside aggressive emissions reductions, we advocate urgent investment in coral reef ecosystem restoration as part of the management toolbox to combat the destruction of reefs as we know them within decades.
