Life on the Edge: Ecosystem Features of Lakes Across a Mountain–Prairie Elevation Gradient in Western Canada

open access: yesEcohydrology, Volume 19, Issue 1, January‐February 2026.
ABSTRACT Ecological transition zones such as mountain elevation gradients can influence the function and productivity of lakes through changes in climatic characteristics and catchment composition (i.e., land use/land cover). However, surveys of limnological features along such ecological transition zones show variable patterns, making it difficult to ...

An ecological study of Rotifera of the Southern Shatt Al-Arab River, Basrah, Iraq

open access: yesالمجلة العراقية للاستزراع المائي, 2022
At three stations of the Shatt Al-Arab River, the ecology of Rotifera was studied: the first Al-Ashar second Abul Khasib and the third Al-Fao. Seasonal horizontal hauls were taken by a plankton net of a mesh-size of 53-µm during 2013. Density of Rotifera

The Seasonal Rhythms of Coastal eDNA: Insights Into Biodiversity and Regional Detection Patterns

open access: yesEnvironmental DNA, Volume 8, Issue 1, January–February 2026.
Seasonal variation affects environmental DNA (eDNA) detection, yet its influence on species monitoring remains underexplored. This study examines eDNA detection windows across taxa, primers, and regions, finding that most species have short detection periods (1–2 months) that vary with taxonomy and primer choice. These results underscore the importance

Characterising Soil Eukaryotic Diversity From NEON Metagenomics Datasets

open access: yesMolecular Ecology Resources, Volume 26, Issue 1, January 2026.
ABSTRACT Belowground eukaryotic diversity serves a vital role in soil ecosystem functioning, yet the composition, structure, and macroecology of these communities are significantly under‐characterized. The National Ecological Observatory Network (NEON) provides publicly available datasets from long‐term surveillance of numerous taxa and ecosystem ...

Plant‐derived environmental DNA reveals fine‐scaled community differentiation in grassland arthropods

open access: yesEcological Applications, Volume 35, Issue 8, December 2025.
Abstract The loss of plant diversity in grasslands is implicated as one of the main causes of arthropod decline. The loss of a single plant species can have a cascading effect on specialized arthropod species. It is thus critical to expand our understanding of plant–arthropod interactions.

Structure and spatial distribution of the rotifer assemblages along a tropical reservoir

open access: yesBrazilian Journal of Biology
The construction of reservoirs is a common practice in the world. These systems modify the hydric landscape and alter the flow of rivers, becoming lotic environments in lentic. Here we investigated the structure and spatial distribution of rotifers along
