Natural ocean acidification at Papagayo upwelling system (north Pacific Costa Rica): implications for reef development [PDF]
Biogeosciences, 2018 Numerous experiments have shown that ocean acidification impedes coral calcification, but knowledge about in situ reef ecosystem response to ocean acidification is still scarce. Bahía Culebra, situated at the northern Pacific coast of Costa Rica, is a

Consensus on future research directions in the phylum Rotifera
Limnology and Oceanography, Volume 71, Issue 7, July 2026.Abstract Rotifers play key roles in aquatic ecosystems, yet significant uncertainty remains about their diversity and evolution, and further evidence is needed to determine how reliably their responses to global change and human impacts can inform conservation.

Environmental Drivers of Jumbo Squid During Fishery Collapse in the Gulf of California (2019–2024)
Fisheries Oceanography, Volume 35, Issue 4, Page 477-491, July 2026.ABSTRACT The jumbo squid (Dosidicus gigas) is a cephalopod endemic to the eastern Pacific with significant ecological and economic importance. Its exploitation in the Gulf of California (GC) peaked in the 1990s, with catches exceeding 100,000 tons, but collapsed in 2009 and virtually disappeared by 2015, largely due to environmental changes and ...

Phytoplankton Communities’ Seasonal Fluctuation in Two Neighboring Tropical High-Mountain Lakes
PlantsHigh-mountain lakes (HMLs) are remote, extreme, and sensitive ecosystems recognized as sentinels of global change. Lakes El Sol and La Luna are very close to each other inside the crater of the Nevado de Toluca volcano, but they differ morphometrically ...

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 5, May 2026.ABSTRACT The Atlantic pygmy devil ray (Mobula hypostoma) is an endangered mobulid species whose conservation is hindered by taxonomic confusion and significant gaps in ecological and life history knowledge. Here, we present an integrative study that clarifies the species' taxonomic status, updates its distribution and synthesizes new and existing data ...
