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 ...

Is it possible to simplify environmental monitoring? Approaches with zooplankton in a hydroelectric reservoir

open access: yesActa Limnologica Brasiliensia, 2017
Aim: In order to contribute to the knowledge about the simplification of biological surveys, this study evaluated the use of substitute groups, numeric and taxonomic resolution for the three main groups of zooplankton (cladocerans, copepods and rotifers)

Zooplankton diversity in highly urbanized ponds: The role of road salt is not reflected by watershed impervious cover

open access: yesLimnology and Oceanography, Volume 71, Issue 1, January 2026.
Abstract Urban ecosystems are structured by multiple anthropogenic stressors, yet despite the increasing extent and rate of urbanization worldwide, the ecological consequences of excessive road salt application and other urban phenomena remain poorly resolved.

Acoustic Observations Unveil Seasonal Fluctuations and Regulation of Zooplankton Biomass and Its Vertical Distribution at a Mid‐Latitude Long‐Term Ocean Observatory

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 1, January 2026.
Abstract Zooplanktonic organisms are considered a key link between different trophic levels. The ecosystem structure and dynamics are affected by changes in their population and phenology. In this work, the causes and timing of changes within the seasonal cycle of zooplankton biomass vertical distribution in oceanic waters of the Bay of Biscay were ...

Under‐Ice Ecological and Biogeochemical Dynamics at the Onset of Spring Thaw in Four Arsenic‐Contaminated Subarctic Lakes

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 131, Issue 1, January 2026.
Abstract Interactions between aquatic organisms and contaminants in under‐ice lake environments are poorly characterized relative to ice‐free seasons. Here, we compared under‐ice arsenic biogeochemical processes and plankton community composition in four subarctic lakes spanning an arsenic contamination gradient.

New Records of Cladocera (Crustacea: Anomopoda) from Laguna Navío Quebrado, La Guajira Department, Colombia

open access: yesNauplius, 2014
Zooplankton plays key roles in structuring interactions in aquatic communities but often remain undescribed in many water systems. This paper reports seventeen species of the Cladocera (Crustacea: Branchiopoda) from Laguna de Navío Quebrado, all of them ...
