Species‐Specific Vulnerability of Northern Red Sea Mesophotic Corals to Accelerated Warming

open access: yesGlobal Change Biology Communications, Volume 1, Issue 2, June 2026.
Mesophotic reefs are often considered climate refuges, yet experimental thermal‐stress reveals species‐dependent vulnerability. Skeletal optics, energy reserves, and light environment determine bleaching severity. A depth‐generalist coral resisted stress while the mesophotic specialist bleached severely.

Diatoms–copepods: An evolutionary arms race

open access: yesLimnology and Oceanography, Volume 71, Issue 4, April 2026.
Abstract Diatoms and copepods are dominating and diverse groups of phytoplankton and zooplankton, respectively. Diatoms account for 25–40% of ocean primary production, and their main predators, copepods, are arguably the most abundant group of metazoans in the ocean, typically accounting for ~ 80% of zooplankton biomass.
