Des méthodes basées sur les peuplements de macrophytes pour évaluer l'état écologique des milieux aquatiques

Sciences, Eaux & Territoires, 2014
Etudier les organismes vivants dans les milieux aquatiques pour en tirer des informations sur les conditions régnant dans leur milieu est l'idée fondatrice du concept de bioindication.

Effect of fish meal replacement by Azolla meal on growth performance, hemato‐biochemical and serum parameters in the diet of scale carp, Cyprinus carpio var. communis

Journal of the World Aquaculture Society, 2023
A 12‐week growth experiment was conducted to evaluate the suitability of Azolla cristata as a fish meal (FM) substitute in diets for Cyprinus carpio var. communis fingerlings.

Modelling fixed plant and algal dynamics in rivers: an application to the River Frome [PDF]

, 2010
The development of eutrophication in river systems is poorly understood given the complex relationship between fixed plants, algae, hydrodynamics, water chemistry and solar radiation.

Associating Local‐Scale Physical Habitat Assemblages With Reach‐Scale Stream Hydrogeomorphological Types in Mountain Headwater Catchments

River Research and Applications, EarlyView.
ABSTRACT Building an understanding of river ecosystems often involves integrating information from different locations, spatial scales and points in time. Geomorphologists and ecologists have long considered ways to explore river ecosystems at different, hierarchical, spatial scales so that features observed locally can be linked to the character of ...

Control of algal growth by macrophytes and macrophyte-extracted bioactive compounds

Water Science and Technology, 1996
Algae (Selenastrum capricornutum and Microcystis aeruginosa) were respectively assayed in a mixed-culture system using various concentrations of macrophytes obtained from Egeria densa, Cabomba caroliniana, and Myriophyllum spicatum in order to evaluate their inhibitory effects on algal growth due to possible secretion of anti-algal bioactive compounds ...

Ecological biomechanics of marine macrophytes

Journal of Experimental Botany, 2022
AbstractMacroalgae and seagrasses in coastal habitats are exposed to turbulent water currents and waves that deform them and can rip them off the substratum, but that also transport essential water-borne substances to them and disperse their propagules and wastes.

Cabomba caroliniana and Schoenoplectus californicus as Antifouling Candidates: Anti‐Attachment and Toxicological Effects in Aurelia coerulea (Cnidaria, Scyphozoa)

Environmental Toxicology, EarlyView.
ABSTRACT Biofouling on artificial surfaces in aquatic ecosystems leads to significant economic losses. Current antifouling paints, while effective, often harm the aquatic environment. This study explores ecologically safe antifouling alternatives derived from plants, focusing on the aquatic macrophytes Cabomba caroliniana (CC) and Schoenoplectus ...

Note – Gestion des Jussies dans le Marais Poitevin

Sciences, Eaux & Territoires, 2014
Le maillage hydraulique dense du réseau hydrographique et la quasi-absence de débit estival font du Marais Poitevin une zone particulièrement favorable aux développements de plantes aquatiques.
