Diversity and Potential Endemism of New Zealand Freshwater Rotifers Revealed Using Mitochondrial DNA Barcodes

New Zealand Journal of Marine and Freshwater Research, Volume 60, Issue 1, March 2026.
Rotifers perform key functions in aquatic food webs and respond to environmental changes, thus providing sensitive indicators of water quality. However, rotifers are small, highly diverse, and difficult to identify for those lacking expertise. Monogononta are the largest taxonomic class of rotifers with over 1500 species described globally, and around ...

The toxicity comparison of metformin and its degradant guanylurea through multi-routes exposure experiments using algae and rotifer

Ecotoxicology and Environmental Safety
Metformin (MET) and its metabolite guanylurea (GUA) are prevalent in aquatic environments, raising concerns about their potential risks to aquatic organisms. However, the toxicity of these compounds through different exposure routes has not been reported.

Effect of chloramphenicol on the life table demography of Brachionus calyciflorus (Rotifera): A multigenerational study

Ecotoxicology and Environmental Safety, 2022
During the last two decades, there has been increasing concerns about the presence of antibiotics in aquatic environments. Phenicol antibiotics, such as chloramphenicol (CMP), commonly used in the veterinary and aquaculture fields to treat infections ...

Evaluation of the pollution pressures posed by groups of chemicals on British riverine invertebrate populations

Biological Reviews, Volume 101, Issue 1, Page 106-127, February 2026.
ABSTRACT Globally, rivers receive a diverse range of chemicals, including metals, pesticides, persistent organic pollutants, petrochemicals, human and veterinary pharmaceuticals and personal care products. However, the extent to which these different chemical groups affect riverine invertebrate communities is not well defined.

Parasites of zooplankton and periphyton assemblages in the littoral zone of lakes in Drawa National Park, Poland

Acta Mycologica, 2013
Studies on parasitism in zooplankton and periphyton assemblages were carried out on samples of water collected from Lakes Płociczno and Płociowe in the Drawa National Park in 2008-2011.

Consistent and flexible maternal effects: how the environments of a mother influence the offspring phenotype

Biological Reviews, Volume 100, Issue 6, Page 2641-2659, December 2025.
ABSTRACT The environment experienced by a mother influences offspring phenotype through maternal effects, which can have significant adaptive benefits for both the mother and the offspring. However, the ways in which maternal environments influence offspring development are extremely diverse, and empirical studies using an outcome‐based approach often ...

Zooplankton Community Composition in the White and Blue Niles Near Khartoum: Combining Molecular and Morphological Approaches

Environmental DNA, Volume 7, Issue 6, November–December 2025.
Environmental DNA (eDNA) metabarcoding of bulk zooplankton from the White and Blue Nile near Khartoum recovered 40 genus/species‐level taxa belonging to Cladocera, Copepoda, and Rotifera, representing 53%–72% of ASVs. Rotifers were the most diverse group, and low Cladocera read counts likely reflect primer mismatch despite similar morphological ...

Local Adaptation? Enhanced Fitness Under Regional UVB Intensities in a Rock Pool Bdelloid Rotifer

Ecology and Evolution, Volume 15, Issue 10, October 2025.
Bdelloids from the Chihuahuan Desert appear to have adapted to regional UVB intensities in a localized manner. Bdelloids exposed to winter or summer levels of UVB intensity had a longer lifespan and a higher net reproductive rate. ABSTRACT Exposure to ultraviolet radiation (UVR) can decrease lifespan and reduce fecundity in aquatic invertebrates ...

Effect of different densities of live and dead Chlorella vulgaris on the population growth of rotifers Brachionus calyciflorus and Brachionus patulus (Rotifera)

Revista de Biología Tropical, 2001
In order to maintain rotifer populations during periods of low algal production, it is necessary to offer alternate diets, some of which include forms of preserved algae.

Optimizing Culture Protocols for Cyclops sp.: Innovations in Density, Feed Composition and Dietary Strategies for Freshwater Aquaculture

Aquaculture, Fish and Fisheries, Volume 5, Issue 4, August 2025.
ABSTRACT Developing optimized feeding strategies for copepods is essential in contemporary aquaculture, as they serve as a highly nutritious live feed for numerous aquatic organisms. Three experiments were conducted to enhance the development and reproductive success of the copepod, Cyclops sp., to support sustainable aquaculture practices.
