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.

Back to life after 50 years: effects of environmental flow restoration on macroinvertebrate biodiversity and river ecological status. A case study of the Valseco stream, Spain

Restoration Ecology, Volume 34, Issue 1, January 2026.
The construction of dams and reservoirs to meet increasing water and electricity demands has significantly altered many natural river flows, posing threats to the ecological integrity of freshwater ecosystems. Environmental flows (e‐flows) have been advocated to mitigate the negative impacts of hydroelectric power generation and to maintain healthy ...

Responses of Oligochaeta and Chironomidae to restoration of connectivity in a river–floodplain stretch of the Upper Danube River

Restoration Ecology, Volume 34, Issue 1, January 2026.
Abstract Introduction In the Upper Danube River, a key goal of river–floodplain restoration is to enhance hydrological connectivity and reduce aquatic habitat isolation and terrestrialization. To evaluate restoration effectiveness, it is crucial to understand the functional responses of freshwater biodiversity and the role of connectivity and ...

First record of Bothrioneurum vejdovskyanum Štolc, 1886 (Oligochaeta, Tubificidae) in Serbia [PDF]

Archives of Biological Sciences, 2012
We report the discovery of Bothrioneurum vejdovskyanum Štolc, 1886 (Annelida: Oligochaeta: Tubificidae: Rhyacodrilinae) in Serbian freshwaters. Fifteen specimens were found in the middle course of the River Ibar (southern Serbia), at a locality where ...

Review and classification of Omethidae (Coleoptera: Elateroidea), with phylogenomic evidence supporting the inclusion of Telegeusinae in the family

Systematic Entomology, Volume 51, Issue 1, January‐March 2026.
This is the first phylogenomic study of Omethidae using genome skimming, sampling representatives of all subfamilies to resolve long‐standing conflicts between morphology‐ and multigene‐based hypotheses. Phylogenomic analyses recovered Omethidae sister to Artematopodidae and strongly support Telegeusinae as a subfamily of Omethidae, rejecting its ...

Influência da contaminação de solo por creosoto na ocorrência de Oligochaeta em fragmentos da Mata Atlântica

Boletim do Observatório Ambiental Alberto Ribeiro Lamego, 2019
Por sua abundante ocorrência e sua sensibilidade a contaminações e variações da presença de nutrientes, as minhocas são importantes bioindicadores da qualidade do solo.

Delineating Diversity‐Based Freshwater Bioregions by Integrating Fish and Macroinvertebrates With Species Distribution Models and Spatial Clustering

Ecology and Evolution, Volume 15, Issue 12, December 2025.
We integrated fish and macroinvertebrate data with species distribution models and spatial clustering to delineate coherent freshwater bioregions. The resulting bioregions captured complementary biodiversity patterns and key transition zones more effectively than single‐taxon or UPGMA clustering.
