Effects of Lateral Hydrological Connectivity on Aquatic Invertebrate Assemblages in Floodplains, Oxbow Lakes and the Main River Channel of the Savannah River, Southeastern USA

Freshwater Biology, Volume 71, Issue 2, February 2026.
ABSTRACT Within river corridors, hydrological connectivity drives the local abiotic and biotic processes, shapes ecosystem functioning and promotes biodiversity. However, hydrological cycling is changing due to climate change, and drought is intensifying and becoming more frequent in many regions of the world, making it critical to understand the ...

Concordance patterns in zooplankton assemblages in the UHE - Luís Eduardo Magalhães reservoir in the Mid-Tocantins river, Tocantins State, Brazil = Padrões de concordância entre grupos zooplanctônicos do reservatório da UHE – Luís Eduardo Magalhães no Médio Tocantins – Estado do Tocatins, Brasil

Acta Scientiarum: Biological Sciences, 2011
The goal of this study was to evaluate the concordance amongst threezooplankton groups (Rotifera, Cladocera, and Copepoda) and between the zooplankton groups and the environmental variables in the Luis Eduardo Magalhães reservoir, in the Mid-Tocantins ...

Zooplankton products on certain sections of the «Dnipro-Donbas» canal

Theoretical and Applied Veterinary Medicine, 2020
In May 2020 the quantitative and qualitative composition of zooplankton as a food item of aquatic bioresources was determined in the water area of the «Dnipro-Donbas» hydrotechnical canal. As a result of complex hydrobiological researches it was revealed

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

Ecohydrology, 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 ...

Patterns of diversity and driving factors in microcrustacean assemblages in the lowland and mountain Arctic: comparison of the Anabar Plateau and the adjacent regions of Middle Siberia

Acta Biologica Sibirica
One of the key problems of modern ecology is to analyze the structure of ecosystems in Arctic water bodies, which are sensitive to global climatic changes and anthropogenic stress.

Invasive Eurasian Minnow Alters the Trophic Niche and Growth of Brown Trout in High‐Latitude Lakes

Ecology of Freshwater Fish, Volume 35, Issue 1, January 2026.
ABSTRACT Invasive species pose a major threat to aquatic ecosystems, particularly in high‐latitude lakes which are characterised by low biodiversity. In northern Europe, the Eurasian minnow (Phoxinus phoxinus) has colonised lakes historically dominated by salmonids, raising concerns about the impacts of invasive cyprinids on native fish populations and

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.

Impact of water level fluctuation in the shaping of zooplankton assemblage in a shallow lake.

Croatian Journal of Fisheries, 2018
Shallow lakes are strongly affected by global climate changes reflected in significant parameters of ecosystem deterioration, i.e. biodiversity decrease, and water turbidity.

Shared and Unique Patterns of Genomic Differentiation and Introgression Between Japanese Stickleback Species Across Three Sympatric Sites

Molecular Ecology, Volume 35, Issue 2, January 2026.
ABSTRACT Hybridization and introgression frequently occur even between distantly related species. A central question in speciation research is which genomic regions act as barriers to gene flow and how genome‐wide differentiation persists despite hybridization between species.
