Hydrologic, Plant and Soil Controls on Microbial Biomass and Enzyme Activities in a Natural and a Restored Freshwater Marsh of Eastern Ontario, Canada

open access: yesFreshwater Biology, Volume 71, Issue 10, October 2026.
ABSTRACT The hydrology and drainage history of freshwater marshes influence their soil properties and plant communities, which in turn affect microbial biomass and extracellular enzyme activities that regulate the biogeochemistry and functioning of the marsh. However, field reports examining the spatial differences and controls of microbial biomass and

Long‐Term Fish Assemblage Responses to Instream Restoration in Boreal Streams: Insights From a 24‐Year BACI Study

open access: yesFreshwater Biology, Volume 71, Issue 10, October 2026.
ABSTRACT Freshwater ecosystems are increasingly threatened by human activities and climate change, emphasizing the need for effective habitat restoration supported by long‐term monitoring. We examined fish species responses to instream restoration in six boreal streams in northern Finland over a 24‐year period (1999–2022) using a Before–After–Control ...

Decadal Shifts in Lake Macrophyte Communities Trace the Impact of Global Change in the Pyrenees

open access: yesFreshwater Biology, Volume 71, Issue 10, October 2026.
ABSTRACT High‐mountain lakes are among the most sensitive ecosystems to global environmental change. Their remote locations and low anthropogenic disturbance make them ideal sentinels for detecting subtle, long‐term ecological responses. This study investigated decadal‐scale changes in aquatic macrophyte communities and water chemistry across a network

Non‐Native Species Alter Functional Diversity Worldwide: A Systematic Review of Competition, Predation and Habitat‐Mediated Effects in Freshwater Ecosystems

open access: yesFreshwater Biology, Volume 71, Issue 10, October 2026.
ABSTRACT The introduction of non‐native species is one of the main threats to biodiversity and ecosystem functioning in freshwater environments, affecting the functional diversity of native communities. Functional diversity, based on phenological, physiological and morphological traits, is a crucial tool for understanding community structure and ...

Influences of a submerged macrophyte on colony formation and growth of a green alga

open access: yes, 2013
The effects of the submerged macrophyte Ceratophyllum demersum on the growth and morphology of the green alga Scenedesmus obliquus were assessed by conducting co-culture laboratory experiments (15 and 25 degrees C, presence/absence of 3 g fresh wt of C ...

Low breeding propensity in a declining Arctic‐breeding swan revealed by telemetry data

open access: yesIbis, Volume 168, Issue 4, Page 1293-1311, October 2026.
Many migratory bird populations are declining in the face of habitat degradation and climate change, making it important to identify which stages of their annual cycle are most affected in order to guide conservation measures. The Bewick's Swan Cygnus columbianus bewickii, an Arctic‐breeding waterfowl species, has suffered a dramatic population decline

Modelling relationships between juvenile brown trout (Salmo trutta L.) density and landscape characteristics: Integration of electrofishing data and spatial data to assess population status

open access: yesJournal of Fish Biology, Volume 109, Issue 4, Page 2094-2115, October 2026.
Abstract Brown trout (Salmo trutta L.) are ecologically and economically important, but like many salmonids their populations are declining. Trout exhibit a high level of phenotypic plasticity, ranging from freshwater residency to anadromy. This complexity causes problems for assessment and constrains application of adult catch‐based assessment methods
