Flow variability and macroinvertebrates jointly regulate stream periphyton and metabolism: Insights from experimental stream mesocosms

Limnology and Oceanography, Volume 71, Issue 1, January 2026.
Abstract Climate change profoundly alters riverine flow regimes and community composition, affecting key ecosystem functions. We used an experimental mesocosm approach to examine how gradual flow velocity reduction (Experiment 1) and flushing events (Experiment 2) influence periphyton community composition and metabolism, with and without a ...

18S rDNA sequences from microeukaryotes reveal oil indicators in mangrove sediment. [PDF]

PLoS ONE, 2010
BackgroundMicroeukaryotes are an effective indicator of the presence of environmental contaminants. However, the characterisation of these organisms by conventional tools is often inefficient, and recent molecular studies have revealed a great diversity ...

Epilithic Algal and Meiofaunal Assemblages of Arctic/Alpine Lakes and Streams Along Latitudinal and Environmental Gradients in Scandinavia

Freshwater Biology, Volume 71, Issue 1, January 2026.
ABSTRACT Epilithic biofilms along a latitudinal gradient of Arctic/alpine lakes and streams were analysed for their composition of algae (incl. cyanobacteria) and meiofaunal assemblages and correlated these with environmental variables. The composition of algal, meiofauna and nematode assemblages differed between lakes and streams.

Ecological Processes Shaping Marine Microbial Assemblages Diverge Between Equatorial and Temperate Time‐Series

Molecular Ecology, Volume 35, Issue 2, January 2026.
ABSTRACT Marine microbial communities are structured by a complex interplay of deterministic and stochastic processes, yet how these vary across latitudes remains poorly understood. Most long‐term microbial observatories are restricted to temperate regions, limiting our ability to assess latitudinal contrasts in microbial dynamics.

Machine learning can refine models of environmental suitability and ecological associations for invasive quagga mussels

Ecosphere, Volume 16, Issue 12, December 2025.
Abstract Dreissenid mussels are among the most prolific aquatic invasive species globally, damaging water industry infrastructure, altering freshwater ecosystem functioning, and costing the global economy millions of US dollars annually. Extensive research has been conducted to predict, prevent, and understand the impacts of dreissenid spread for zebra
