Temporal dynamics of mesopelagic fishes within a mesoscale eddy: A Lagrangian perspective

Limnology and Oceanography Letters, Volume 11, Issue 3, May 2026.
Abstract Mesoscale eddies are physically dynamic environments, yet biological responses within them are often treated as static, with eddy polarity (anticyclones vs. cyclones) serving as the dominant conceptual framework. Temporal dynamics of animals within eddies—particularly at mid‐trophic levels—remain largely unresolved.

The Abrupt and Persistent Decline in Recruitment Success in Northeast Arctic Cod: A Review of Probable Causes

Fish and Fisheries, Volume 27, Issue 3, Page 643-659, May 2026.
ABSTRACT Most of the previously large cod stocks in the North Atlantic are depleted to very low levels. A notable exception has been the Northeast Arctic cod inhabiting the Barents Sea. This cod stock reached a record high level around 2013, but since then has declined sharply, with older fish being fished out and few new recruits entering the stock ...

Macroinvertebrates Associated with Macroalgae within Integrated Multi-Trophic Aquaculture (IMTA) in Earthen Ponds: Potential for Accessory Production

Journal of Marine Science and Engineering
The present work aims to evaluate the macroinvertebrate community associated with macroalgae in earthen pond systems to better understand their potential in detritus recycling and as an accessory production. Sampling took place on the settling pond of an

Trophic Niche Overlap Between the Invasive Crab Rhithropanopeus harrisii (Gould, 1841) and Native Crab Species in the Southwest Atlantic Coast

Marine Ecology, Volume 47, Issue 3, May/June 2026.
ABSTRACT The introduction of exotic species is one of the main drivers of biodiversity loss in aquatic ecosystems. The Harris mud crab Rhithropanopeus harrisii, native to the Atlantic coast of North America, was recorded in the Patos Lagoon estuary (southern Brazil) in the 1980s, likely introduced via ballast water. However, the effects of this invader

Tidal reinstatement of coastal wetlands: a global review

Restoration Ecology, Volume 34, Issue 4, May 2026.
Abstract Introduction Coastal wetland restoration is a global priority due to its critical role in enhancing climate resilience and biodiversity. Tidal reinstatement, through the removal or modification of tidal barriers, is a promising method to restore these ecosystems.
