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)

Faunistic analysis of freshwater zooplankton in small rock pools of Maritime Antarctica

open access: yesУкраїнський антарктичний журнал, 2022
Small water bodies like the rock pools are used as a model system for evolutionary and environmental studies with a growing interest. The zooplankton in the rock pools is a most interesting and promising research object.

Phenology, food webs, and fish: The effects of shifted ice phenology across multiple trophic levels

open access: yesEcosphere, Volume 16, Issue 12, December 2025.
Abstract Winter plays a crucial role in structuring temperate aquatic ecosystems, influencing the timing of multiple processes across trophic levels including phytoplankton blooms, zooplankton production, and the reproduction and recruitment of fish species like walleye (Sander vitreus).

Effects of environmental factors on species diversity of rotifers using biodiversity indicators and canonical correlation analysis (CCA) [PDF]

open access: yesبوم‌شناسی آبزیان, 2017
Rotifers are microscopic aquatic animals of phylum Rotifera, live in a diverse range of aquatic habitats. They are important in ecology of freshwater ecosystems by recycling nutrients and can alter trophic dynamic of planktonic communities.

Elevated carbon dioxide can boost freshwater zooplankton abundance, while warming may shift community composition, weakening phytoplankton control

open access: yesLimnology and Oceanography, Volume 70, Issue S2, Page S273-S288, December 2025.
Abstract Zooplankton communities in ponds and lakes control phytoplankton growth and serve as a food source for higher trophic levels such as fish. Recent experiments have shown that several freshwater zooplankton species as well as the phytoplankton communities on which they feed can be variably affected by rising temperatures, reduced pH and higher ...

Microbial Community Dynamics in Early Tufa Biofilms

open access: yesMicrobiologyOpen, Volume 14, Issue 6, December 2025.
Microbial succession shapes the early development of tufa biofilms in karst freshwater systems, with prokaryotic communities stabilizing rapidly and microeukaryotes contributing to extracellular polymeric substance production and carbonate entrapment. Site‐specific hydrodynamics and organic inputs drive community specialization, ultimately influencing ...

Wetland biodiversity in Aotearoa New Zealand: an eDNA perspective on exotic and non‐exotic species

open access: yesNew Zealand Journal of Zoology, Volume 52, Issue 4, Page 410-427, December 2025.
ABSTRACT Invasive species threaten biodiversity in Aotearoa New Zealand. In wetlands − significant sites that provide an array of ecosystem and cultural services but represent <10% of their original extent − invasive species can affect hydrological function, nutrient regimes and overall ecological functionality.
