Large deep-sea zooplankton biomass mirrors primary production in the global ocean
Nature Communications, 2020 Zooplankton biomass in the dark ocean is thought to be low and weakly coupled to epipelagic primary production, but recent evidence suggests otherwise.

Journal of Fish Biology, EarlyView.Abstract Deep‐sea elasmobranchs are less resilient to the increasing scale of anthropogenic impacts such as fisheries, owing to their life‐history traits. The necessity for proper management measures is hampered by the scant knowledge on these taxa and their biology. Here we provide the first comprehensive insight into the parasite infracommunities and

Environmental Microbiology Reports, Volume 18, Issue 3, June 2026.Changes in DOM composition influence prokaryotic species growth in the Mediterranean Sea, shaping their metabolic responses and organic matter processing. In our study, higher DOP consumption and alkaline phosphatase activity led to the accumulation of recalcitrant DOM, highlighting how microbial community shifts drive distinct pathways in carbon ...

Deep‐pelagic fishes: Demographic instability in a stable environment
Ecology and EvolutionDemographic histories are frequently a product of the environment, as populations expand or contract in response to major environmental changes, often driven by changes in climate.

Limnology and Oceanography: Methods, Volume 24, Issue 5, May 2026.Abstract Investigations of hydrostatic pressure effects on microbial enzymatic processing are challenging but critical for understanding element cycling in the world's oceans. In this study, we developed and tested a stainless‐steel pressure cell capable of withstanding up to 110 MPa of hydrostatic pressure (equivalent to ~ 11,000 m depth), featuring ...

Mesoscale eddies: Hotspots of prokaryotic activity and differential community structure in the ocean [PDF]
, 1993 14 pages, 9 figures, 2 tablesTo investigate the effects of mesoscale eddies on prokaryotic assemblage structure and activity, we sampled two cyclonic eddies (CEs) and two anticyclonic eddies (AEs) in the permanent eddy-field downstream the Canary Islands.

Respiration Rates in the Global Mesopelagic Ocean
Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.Abstract Respiration in the mesopelagic layer of the oceans (200–1,000 dbar) is a key factor controlling the biological carbon pump, as it attenuates the downward flux of organic carbon to the ocean interior. Using a global data set of dissolved oxygen and transient tracer gas measurements, we report spatially resolved oxygen utilization rates (OUR ...
