Recognizing the significance of the life stage of fish for nano-eco-toxicological studies, the acute toxicity of colloidal silver nanoparticles (AgNPs) was tested in three different life stages of rainbow trout. Fishes were exposed to colloidal AgNPs at nominal concentrations of 100, 32, 10, 3.2, 1, 0.32, 0.1, and 0.032 mg/L. The estimated 96 hr LC50 values were 0.25, 0.71, and 2.16 mg/L for th...

Ephemeral emergent insects, such as mayflies (Hexagenia spp.), are commonly used as biomonitors of persistent organic pollutants (POPs) and provide a vector for aquatic-terrestrial contaminant transfer. Mayflies bioaccumulate sediment-associated contaminants by bioconcentration and biomagnification during the aquatic stage and concentrate POP residues postemergence due to bioamplification, whic...

Most ectothermic organisms mature at smaller body sizes when reared in warmer conditions. This phenotypically plastic response, known as the "temperature-size rule" (TSR), is one of the most taxonomically widespread patterns in biology. However, the TSR remains a longstanding life-history puzzle for which no dominant driver has been found. We propose that oxygen supply plays a central role in e...

© Thinkk/y-studio W ater is essential to life, supporting the food web and habitat for much of Earth’s wildlife. Pesticides often contaminate U.S. waterways and threaten aquatic organisms, from invertebrates (worms, molluscs, insects, and zooplankton) to vertebrates (fish and amphibians), and microorganisms (bacteria, fungi, protozoa, algae, and phytoplankton), as well as those that depend on t...

DNA-based methods continue to unveil the diversity and evolutionary origins of life on Earth. 'Next generation' methods have just solved a long-standing puzzle by uncovering previously unseen yet globally distributed diversity within a lineage of amitochondriate parasites affecting commercially exploited aquatic hosts. This discovery will impact both pure and applied research fields.

Many plant seeds and invertebrates can survive passage through the digestive system of birds, which may lead to long distance dispersal (endozoochory) in case of prolonged retention by moving vectors. Endozoochorous dispersal by waterbirds has nowadays been documented for many aquatic plant seeds, algae and dormant life stages of aquatic invertebrates. Anecdotal information indicates that endoz...

Fungi make up one of the most diverse, ecologically important groups of eukaryotes. The vast majority of fungi are terrestrial, but the chytridiomycetes, a basal group of fungi, includes flagellated, unicellular, aquatic forms, and it is likely that this was the ancestral condition of the group (1). The more derived groups of fungi—zygomycetes, ascomycetes, and basidiomycetes—are all predominan...
