Low‐Head Dam Removal Restores Biofilm Structure but Not Function in a Temperate Stream

International Review of Hydrobiology, Volume 111, Issue 1, June 2026.
ABSTRACT Barrier removal is a common stream restoration practice aimed at restoring longitudinal connectivity, yet its effects on biofilm structure and function, through alteration of near‐bed hydrodynamics, remain unclear. Using a space‐for‐time substitution approach, we assessed how the presence and removal of a low‐head dam affect biofilm structure ...

Topic Modeling of Fatty Acid Studies: Evaluating Environmental Changes in Freshwater Ecosystems

International Review of Hydrobiology, Volume 111, Issue 1, June 2026.
ABSTRACT Fatty acids (FAs) are biochemical molecules with vital structural and metabolic functions in all living organisms. Over the last decades, FA analysis in ecological studies has garnered significant attention due to its diverse applicability, such as taxonomic support for species identification, investigations on trophic interactions, and ...

Acclimation of Charophytes to Spectral Composition of Light at Limiting Irradiances

International Review of Hydrobiology, Volume 111, Issue 1, June 2026.
ABSTRACT Irradiance is regarded as a key factor determining the maximum colonization depth (Z0) of submerged macrophytes. However, the relevance of acclimation capabilities to spectral composition under such low‐light conditions remains poorly understood.

Urea provides an important nitrogen source for microbial populations in an ultraoligotrophic sea

Limnology and Oceanography, Volume 71, Issue 6, June 2026.
Urea is an organic nitrogen (N) compound directly utilized by both heterotrophic prokaryotes and some photoautotrophs. Reports of either ambient urea concentrations or urea uptake rates from the ultraoligotrophic eastern Mediterranean Sea are lacking. We investigated urea distribution and uptake in the upper water column in the Levantine basin during ...

Hydrological seasonality shapes microbial biomass and diversity in an equatorial estuarine mangrove

Limnology and Oceanography, Volume 71, Issue 6, June 2026.
Abstract Mangroves are pantropical marine forests rooted in soft sediments and subject to pronounced seasonal variability. However, the effects of these hydrological fluctuations on root‐associated prokaryotic communities remain poorly understood, particularly in underexplored regions like the Guianas.

Species‐specific processing of fluorescent dissolved organic matter by Caribbean sponges

Limnology and Oceanography, Volume 71, Issue 6, June 2026.
Coral reefs are biodiverse and productive ecosystems that are found in typically oligotrophic environments. Many studies have attempted to explain this paradox by demonstrating that microbial symbionts expand metabolic capabilities of host animals.
