Quantifying Viral Lysis in Microalgae Using Cell‐Free rRNA

open access: yesMicrobiologyOpen, Volume 15, Issue 5, October 2026.
Cell‐free ribosomal RNA (rRNA) dissolved in seawater provides a quantitative proxy for viral lysis in microeukaryotic phytoplankton. Incubation experiments with two distinct host–virus systems revealed marked increases in cell‐free rRNA production per cell, a proxy for lytic mortality, reaching up to 46‐ and 302‐fold relative to noninfected controls ...

Drivers of stability in plankton communities: dominance, asynchrony, and averaging effects across temporal, spatial and trophic scales

open access: yesOikos, Volume 2026, Issue 10, October 2026.
The origins of ecosystem stability have long intrigued ecologists. Recent theoretical advancements highlight three primary mechanisms driving stability: dominance, asynchrony and averaging. While plant community stability has been extensively studied, our understanding of marine community stability remains limited. Plankton, as key components of marine

Drivers of metabolic density‐dependence: how resource availability and conspecific cues affect phytoplankton metabolism

open access: yesOikos, Volume 2026, Issue 10, October 2026.
Metabolism is density‐dependent from unicellular to multicellular organisms. Understanding what drives metabolic suppression is important to explain population growth given the link between metabolism and biomass production. In the simplest scenario, metabolic suppression is caused by a reduction in resource availability with increasing population ...

Resource competition between buoyancy‐regulating and sinking phytoplankton species along a stratified water column

open access: yesOikos, Volume 2026, Issue 10, October 2026.
In temperate lakes, plankton dynamics are closely linked to seasonal shifts in water stratification, following air temperature. The onset of summer stratification typically coincides with the formation of an algal spring bloom in the well‐mixed surface layer (epilimnion).

A tipping point for tipping points

open access: yesOikos, Volume 2026, Issue 10, October 2026.
Tipping points (TPs) – often understood as abrupt changes to a system – have become a popular framework for ecology and environmental science across spatial and temporal scales. The underlying, quantitative foundation of TP theory is built on mathematical models from catastrophe and predator–prey theories.

The Employment of Hydrogen Peroxide in Water Disinfection Poses a Threat to Aquatic Ecosystems Because of Its Toxicity to Nontarget Organisms

open access: yesEnvironmental Toxicology, Volume 41, Issue 10, Page 1060-1068, October 2026.
ABSTRACT Hydrogen peroxide is widely used in water and wastewater treatment, particularly in advanced oxidation processes that aid in the degradation of compounds and microbial disinfection. Despite concerns about potential environmental contamination, its impact on freshwater ecosystems remains inadequately studied.

Metabolic Dynamics of an Offshore Coral Reef in the Central Red Sea: Observations From Autonomous Sensors

open access: yesGlobal Biogeochemical Cycles, Volume 40, Issue 10, October 2026.
Abstract Coral reefs are increasingly threatened by local and global stressors. Traditional visual reef monitoring methods are time‐intensive and provide only a snapshot of reef condition. Recent efforts aim to measure reef metabolism, or the balance of net community production (NCP) and net community calcification (NCC), as coral reef carbonate ...

Seasonal Variations in Aerosol Trace Element Source Contributions and Deposition Fluxes to the North Pacific Subtropical Gyre

open access: yesGlobal Biogeochemical Cycles, Volume 40, Issue 10, October 2026.
Abstract Trace elements deposited in the marine environment affect ocean biogeochemistry in numerous, complex ways. This study quantifies seasonal aerosol trace element (TE) fluxes and evaluates their variability and potential sources over a 2‐year period in the North Pacific subtropical gyre (NPSG). We established the Hawaii Aerosol Time Series (HATS),
