The surface reactivity of iron oxide nanoparticles as a potential hazard for aquatic environments: A study on Daphnia magna adults and embryos [PDF]
, 2018 open5noNano-ecotoxicology is extensively debated and nanomaterial surface reactivity is an emerging topic. Iron oxide nanoparticles are widely applied, with organic or inorganic coatings for stabilizing their suspensions.

Journal of Applied Toxicology, EarlyView.ABSTRACT The expanding demand for platinum group elements (PGEs) in industrial and medical applications has led to their increasing accumulation in aquatic sediments. However, their ecological impacts remain poorly understood, particularly for sediment‐dwelling invertebrates. This study assessed the toxicity of platinum (Pt) and palladium (Pd) across a

The Daphnia bioassay: a critique [PDF]
Hydrobiologia, 1989 Daphnia magna is used widely as a standard ecotoxicological indicator organism, and protocols exist for its use in assessing the toxicity of substances under acute and chronic experimental conditions. Problems exist in repeatability of such bioassays between laboratories.

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.ABSTRACT Amphibians are the most threatened vertebrate class globally. Climate change, agrochemicals, and/or pathogens and parasites are implicated in contributing to amphibian declines, either singly or in combination. We investigated individual and combined effects of elevated temperatures and atrazine (2.0 μg/L) on Lithobates [formerly Rana] pipiens

Evaluation of Possible Causes of Non-Predatory Mortality of Crustacean Zooplankton in a Small Siberian Reservoir [PDF]
Журнал Сибирского федерального университета: Серия Биология, 2008 Non-predatory specific mortality (NPSM) of dominant zooplankton species, Daphnia (longispina group) and Cyclops vicinus, was estimated during 1997-2000 sampling seasons on the basis of a new direct method: live/dead sorting and sediment trap measurements.

Limnological study of Zealand Pond, White Mountains, New Hampshire [PDF]
, 1999 Zealand Pond, New Hampshire, was chosen as the site of a remote lake study. Data were collected between July 18 and August 29,1997. Zealand Pond had a relatively high pH (6.3-6.9) and alkalinity (2.3- 3.1 mg CaCO3 /liter), considering its small size and ...

A new reference genome assembly for the microcrustacean Daphnia pulex [PDF]
, 2017 Comparing genomes of closely related genotypes from populations with distinct demographic histories can help reveal the impact of effective population size on genome evolution. For this purpose, we present a high quality genome assembly of Daphnia pulex (

Improved COI taxonomic assignment workflow enhances detection of invertebrates in environmental DNA
Limnology and Oceanography: Methods, EarlyView.Abstract Environmental DNA (eDNA) metabarcoding is an increasingly popular and powerful tool in ecology, offering a non‐invasive method to assess biodiversity and monitor ecosystem health across diverse environments. While the mitochondrial cytochrome c oxidase subunit I (COI) gene is one of the most widely used markers for studying eukaryotic ...
