Validated habitat mapping links ocean floor features to biological communities
Seamount slopes and guyot summits are not just geological features, they are biological neighborhoods. Our study of the Northwest Pacific tested whether environmental data alone can map those neighborhoods. It cannot. By adding sparse biological records into a dual-path classification framework, we uncovered latitudinal patterns in benthic communities that bathymetry alone missed. This matters for conservation: 12 candidate areas covering 27% of the region now await representativeness assessment.
Coastal benthic ecosystems reveal the cumulative toll of climate and human pressures
Coastal benthic ecosystems are telling us something urgent. Rising temperatures, acidification, and deoxygenation now converge with eutrophication, pollution, and bottom trawling, reshaping biodiversity from shallow coasts to continental margins. These compounded stressors simplify assemblages, alter trophic pathways, and push ecosystems toward critical thresholds. Yet recent advances, environmental DNA metabarcoding, automated imaging, multi-stressor experiments, are sharpening our ability to detect and understand these changes at scale.
Deeper Insights: Carbonate Production in the Sicilian Channel
The Mediterranean's mesophotic zone remains a scientific gap, but new work from the Sicilian Channel is closing it. Analysis of seafloor samples from the R/V Meteor M191 expedition reveals a clear split: coralline algae thrive on Terrible Bank's shallow, irregular summit, while Nameless Bank's deeper, smoother surface hosts only dead crusts. Aphotic depths shift to cold-water corals and oysters. Topography and hydrodynamics drive this distribution, and the slow accumulation rates, paired with abandoned fishing gear, highlight how fragile these ecosystems are.
