Importance relative de l'eau et de la nourriture comme source de cadmium chez la larve de l'insecte Sialis velata (megaloptera). [PDF]

, 1998
Le cadmium (Cd) est considéré comme un métal potentiellement dangereux pour les organismes qui y sont exposés. Des industries ont contribué, au cours des années, à relarguer de grandes quantités de ce métal dans l'environnement.

Fish predation cues induce drifting and emergence in an experimental stream mesocosm system

Limnology and Oceanography, Volume 70, Issue S2, Page S364-S376, December 2025.
Abstract Predator–prey interactions are important drivers of adaptation in aquatic communities, shaping the behavior of invertebrates with cascading effects on community dynamics. Behavioral responses, such as moving with the downstream current (drift) or altering the timing of emergence, are strategies that reduce the risk of predator encounters ...

Development of a non‐lethal stomach content analysis method for freshwater eels: An empirical evaluation of the tube method for Anguilla marmorata

Journal of Fish Biology, Volume 107, Issue 6, Page 1995-2004, December 2025.
Abstract Understanding the feeding habits of predatory fish is essential for unravelling food web structures and implementing conservation strategies in riverine ecosystems. However, conventional lethal stomach content analysis methods are not necessarily appropriate for long‐term dietary studies, particularly for threatened species, as they require ...

Predator Size Structure Fails to Alter Nonconsumptive Effects in Streams

Ecology and Evolution, Volume 15, Issue 11, November 2025.
Stonefly predators caused pervasive nonconsumptive effects on benthic invertebrates in a headwater stream. These effects did not depend on stonefly size structure. Predator biomass may be the key determinant of stonefly induced nonconsumptive effects in streams.
