Biogeography of the ‘water flea’ Daphnia O. F. Müller (Crustacea: Branchiopoda: Anomopoda) on the Indian subcontinent

Journal of Limnology, 2016
Studies on Daphnia distribution in Indian subcontinent have been few and regionally restricted despite Daphnia being by far the most studied cladoceran.

Nanomaterials' Multigenerational Effects by Single and Joint Exposure in Non‐mammalian Models

Environmental Toxicology, Volume 41, Issue 10, Page 957-974, October 2026.
ABSTRACT Nanotoxicology has mainly focused on single‐generation studies, leaving multigenerational toxicity underexplored. Having animal welfare recently gained importance, we aimed to provide the state‐of‐the‐art of knowledge about multigenerational effects in non‐mammalian models in the case of nanomaterials (NM) single and joint exposure to other ...

Cyanopeptide Mixtures Induce Variable Synergistic and Antagonistic Effects Across Diverse Human Cell Lines

Environmental Toxicology, Volume 41, Issue 10, Page 807-821, October 2026.
ABSTRACT Cyanobacterial harmful algal blooms (cyanoHABs) threaten human, animal, and ecosystem health and safety through production of toxic secondary metabolites. Microcystis, a cosmopolitan bloom‐forming cyanobacterial genus, is well‐known for producing hepatotoxic microcystins (MCs), but it can produce many other bioactive cyanopeptides, such as ...

The Employment of Hydrogen Peroxide in Water Disinfection Poses a Threat to Aquatic Ecosystems Because of Its Toxicity to Nontarget Organisms

Environmental Toxicology, Volume 41, Issue 10, Page 1060-1068, October 2026.
ABSTRACT Hydrogen peroxide is widely used in water and wastewater treatment, particularly in advanced oxidation processes that aid in the degradation of compounds and microbial disinfection. Despite concerns about potential environmental contamination, its impact on freshwater ecosystems remains inadequately studied.

A Tale of Two Lakes: Divergent Evolutionary Trajectories of Two Daphnia Populations Experiencing Distinct Environments

Ecology and Evolution
Most studies of local adaptation substitute the correlation between spatial distance and environmental heterogeneity for the temporal dynamics over which local adaptation evolves.

The Effects of Nutrient Additions on Kokanee in Dworshak Reservoir, Idaho

Fisheries Management and Ecology, Volume 33, Issue 5, Page 949-962, October 2026.
ABSTRACT We investigated the effects of whole reservoir nitrogen (N) addition on kokanee growth in Dworshak Reservoir, Idaho. We hypothesized that N addition would improve the growth of kokanee (Oncorhynchus nerka) at a given level of abundance by increasing the availability of Daphnia, an important food source.

Live observation of the oviposition process in Daphnia magna.

PLoS ONE, 2019
In favorable conditions, Daphnia magna undergoes parthenogenesis to increase progeny production in a short time. However, in unfavorable conditions, Daphnia undergoes sexual reproduction instead and produces resting eggs.

Clean Synthesis of N‐4‐Alkylamino‐7‐chloroquinoline Cyclic Imides: Influence of Lipophilicity on Antibacterial and Ecotoxicological Properties

Chemistry &Biodiversity, Volume 23, Issue 9, September 2026.
For series 2a–d, there appears to be optimal activity against Klebsiella pneumoniae when lipophilicity is intermediate (log P 2.64 for 2b). Similarly, for series 2e–g, activity against Pseudomonas aeruginosa, Staphylococcus aureus and Streptococcus mutans also increases (log P 3.71 for 2f).

Computational Fluid Dynamics Reveal Hydromechanical Adaptations of Ceriodaphnia dubia as an Inducible Defence Against the Carnivorous Plant Utricularia × neglecta

Ecology and Evolution, Volume 16, Issue 9, September 2026.
This study investigates an inducible defence of Ceriodaphnia dubia against the carnivorous plant Utricularia × neglecta using computational fluid dynamics. Simulations comparing the typical and plant‐exposed morph show that the induced morphology reduces drag and, together with proportionally smaller second antennae, likely lowers the probability of ...
