Marine trophic architecture and hidden ecological connections in the Strait of Magellan: keystone species and ecosystem resilience

open access: yesOikos, Volume 2026, Issue 4, April 2026.
Understanding the ecological implications of species coexistence is central to biodiversity studies and to identify environmental and anthropogenic drivers of ecosystem dynamics, where ecological network analysis offers valuable insights. This study examines the complexity, structure, and potential responses to disturbances of the Strait of Magellan's ...

Palaeoenvironmental evolution of the Baltic Sea basin during the Last Interglacial (Eemian, Mikulino stages)—a review

open access: yesBoreas, Volume 55, Issue 2, Page 282-307, April 2026.
This review presents an investigation of the evolution of the Baltic Sea basin and its connections through the Eemian Stage, based upon sequences of marine and associated deposits from the White Sea to the Southwest Baltic, via the Karelian channel. Pollen analyses, foraminiferal and ostracod analyses provide the evolution of relative sea‐level change,

Metabarcoding and biomass quantification reveal seasonal parasite associations in copepods

open access: yesLimnology and Oceanography, Volume 71, Issue 2, February 2026.
Abstract Parasites are important members of ecosystems, and recent metabarcoding efforts have revealed an abundance of microbial eukaryotic parasites in copepods. However, a putative linkage to host community biomass and composition has not been addressed. We performed zooplankton tows monthly for 2 yr at five stations in the Oslofjord, Norway.

Effects of salinization on tropical freshwater wetland primary producers and aquatic invertebrates

open access: yesOikos, Volume 2026, Issue 2, February 2026.
Sea level rise is expected to transform coastal aquatic ecosystems world‐wide. The freshwater wetlands of tropical northern Australia are among the most biodiverse and productive ecosystems on the continent, but owing to high regional rates of sea level rise coupled with low‐lying land and large tides they are increasingly affected by saltwater ...
