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 ...

Hidden Waters, Unique Communities: Subterranean Zooplankton Beta Diversity in the Caatinga Drylands
Freshwater Biology, Volume 71, Issue 4, April 2026.ABSTRACT Subterranean waters are important but understudied biodiversity reservoirs, particularly in the semi‐arid Caatinga biome. We quantified the biological uniqueness of zooplankton communities in these groundwater‐dependent systems and investigated how environmental conditions shape beta diversity.
