Spatial and Temporal Variability of Eastern Pacific Radiocarbon and Carbon Chemistry From the Ice Age to Today

Paleoceanography and Paleoclimatology, Volume 41, Issue 5, May 2026.
Abstract Proxy records of seawater radiocarbon (14C/C) provide strong constraints on how changes in ocean ventilation contributed to the increase in atmospheric CO2 during the termination of the last ice age (≈18,000‐to‐12,000 years ago). One outstanding problem, however, is the existence of anomalously low deglacial benthic foraminiferal 14C/C in the ...

Expansion of the Eastern Tropical North Pacific Oxygen Minimum Zone During the Last Deglaciation Recorded by Planktic Foraminifera

Paleoceanography and Paleoclimatology, Volume 41, Issue 5, May 2026.
Abstract Climate change is currently driving the expansion of oxygen minimum zones (OMZs), areas of the open ocean with consistently low oxygen levels. Changes in temperature, productivity and consequent respiration, and water mass ventilation drive OMZ expansion and contraction with implications for ecosystem function and biogeochemical cycling ...

Latitudinal Gradients of Species Richness in Marine Benthos: Insights From Japan's Tidal Flat Areas

Ecological Research, Volume 41, Issue 3, May 2026.
Latitudinal diversity gradients in species richness were observed in the coasts of Japan. Extensive tidal flats and biogeographical connectivity to the Eurasian Continent may cause the unexpected peak in species diversity at the Kyushu region. Mollusca was the dominant taxonomic group, followed by Malacostraca, Annelida, and other benthic groups ...

Resilience to Cardiac Aging in Greenland Shark Somniosus microcephalus

Aging Cell, Volume 25, Issue 5, May 2026.
Greenland shark Somniosus microcephalus shows severe cardiac aging such as fibrosis, lipofuscin buildup, mitochondrial damage, and oxidative stress, unseen in comparison species Etmopterus spinax and Nothobranchius furzeri, yet remain healthy. S. microcephalus resilience suggests unique mechanisms that preserve heart function for centuries, offering ...
