ABSTRACT The piscicide antimycin has been used as an effective fish toxicant to eradicate nuisance fishes because it is not as detectable by fish as other chemical piscicides. We evaluated the effects of antimycin and its detoxicant, potassium permanganate, on periphyton and benthic macroinvertebrates during a brook trout (Salvelinus fontinalis ...

Order Trichoptera Kirby, 1813 (Insecta), Caddisflies* [PDF]
The taxonomy, diversity, and distribution of the aquatic insect order Trichoptera, caddisflies, are reviewed. The order is among the most important and diverse of all aquatic taxa. Larvae are vital participants in aquatic food webs and their presence and relative abundance are used in the biological assessment and monitoring of water quality.

Preliminary indoor evidences of microplastic effects on freshwater benthic macroinvertebrates
Plastics are to date considered one of the main detrimental drivers for the health of aquatic ecosystems, both in marine and inland waters. Regarding the latter habitat, it seems surprising how the plastic effects on benthic invertebrates are neglected ...

Captive coral aquaculture is increasingly important for both the aquarium trade and reef restoration, but production can be undermined by hard‐to‐detect pests such as the Acropora‐eating flatworm Prosthiostomum acroporae. We developed and validated a highly sensitive ddPCR assay capable of detecting P.

Evolution of Animal Parasitism in Nematodes of the Suborder Spirurina
This study reconstructs the evolutionary history of parasitism in Spirurina by integrating ancestral state reconstruction (ASR) with a comprehensive phylogenetic framework. Our analyses reveal clear patterns of hostswitching and major transitions in host associations, providing the first broad evolutionary perspective on parasitism within this group ...

ABSTRACT The amphibian disease chytridiomycosis, caused by the fungal pathogen Batrachochytrium dendrobatidis (Bd), has devastated global amphibian biodiversity. The specific reasons for its rapid global spread, especially to pristine areas, are not well understood. Freshwater invertebrates might function as carriers of Bd, but the diversity and extent

Abstract Predicted increases in stream temperature are expected to accelerate organic matter decomposition in rivers. In detrital stream food webs, carbon use efficiency (CUE)—the proportion of consumed carbon (C) retained as biomass—determines whether C is stored in organisms or rapidly lost as CO2.
