Feeding ecology of an Amazonian electric knifefish under altered flood‐pulse dynamics caused by hydroelectric damming

Journal of Fish Biology, EarlyView.
Abstract This study evaluated the effects of the controlled flood pulse on diet composition, trophic niche breadth and feeding intensity of Archolaemus janeae, an electric knifefish species with a restricted distribution in the Amazon Basin. Monthly samples were collected from December 2020 to November 2021 in the Volta Grande stretch of the Xingu ...

Differential effects of freshwater browning across fish species: consequences for individual‐ to community‐level fish traits in north temperate lakes

Biological Reviews, Volume 101, Issue 1, Page 128-146, February 2026.
ABSTRACT The browning of freshwater ecosystems is increasingly evident in temperate and northern regions, with widespread ramifications for lake physics, chemistry, and biology. Contrasting results on how freshwater browning may impact fish have been reported, but there has been no comprehensive examination of how browning may cause cascading effects ...

Vegetation biomass and landscape context influence web‐building spider dietary breadth in urban vacant lots

Ecological Entomology, Volume 51, Issue 1, Page 126-140, February 2026.
Spider dietary breadth and overlap increased with imperviousness, suggesting that prey and spiders are concentrating in vacant lots in these landscapes. Higher vegetation biomass, which results from reduced mowing frequency, was associated with increased dietary breadth and shared prey between spiders.

Characterization of the Omnivorous Lygus lineolaris Diet in a Strawberry Field by Metataxonomy

Ecology and Evolution, Volume 16, Issue 1, January 2026.
This study employs metataxonomy to reveal the extensive omnivorous diet of Lygus lineolaris in a strawberry field, identifying 475 host taxa and confirming active ingestion across plant and prey sources. We introduce a novel coefficient of omnivory, demonstrating the species' strong herbivorous bias while highlighting its dietary flexibility and ...
