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.

Benthic megafauna and the functioning of macroalgal forests and urchin barrens

Oikos, EarlyView.
Two temperate rocky reef food‐web models, representing the trophic diversity of the Mediterranean rocky reef communities, were built for the two stable states: macroalgal forests and barren grounds, which are characterized by opposite amounts of erect macroalgal biomass.

Go hard or go home: Major removal of woody vegetation and sediment greatly enhances wetland plant and water beetle diversity recovery in a farmland pond landscape

Ecological Solutions and Evidence
Ponds are important habitats for biodiversity conservation and ecosystem service provisions in farmland settings. Agricultural intensification and cessation of traditional management have resulted in a substantial loss of open‐canopy farmland ponds ...

Ailleurs en Europe - Les plantes aquatiques invasives aux Pays-Bas

Sciences, Eaux & Territoires, 2014
La gestion des plantes aquatiques invasives aux Pays-Bas s'appuie à la fois sur des améliorations de la règlementation, de l'information du public, la mise en place d'un code de conduite signé par de nombreux partenaires publics et privés, et sur des ...

Does Long-Term Macrophyte Management in Lakes Affect Biotic Richness and Diversity? [PDF]

, 2005
We hypothesize that the richness and diversity of the biota in Lake Moraine (42°50’47”N, 75°31’39”W) in New York have been negatively impacted by 60 years of macrophyte and algae management to control Eurasian watermilfoil ( Myriophyllum spicatum L.

Effects of water temperature on summer periphyton biomass in shallow lakes: a pan-European mesocosm experiment [PDF]

, 2015
Periphyton communities play an important role in shallow lakes and are controlled by direct forces such as temperature, light, nutrients, and invertebrate grazing, but also indirectly by planktivorous fish predation.

A DNA mini‐barcode for marine macrophytes [PDF]

Molecular Ecology Resources, 2020
AbstractStudies focusing on marine macrophyte metabarcoding from environmental samples are scarce, due to the lack of a universal barcode for these taxa, and to their poor representation in DNA databases. Here, we searched for a short barcode able to identify marine macrophytes from tissue samples; then, we created a DNA reference library which was ...

Connecting the distribution and diversification of marine plants

Oikos, EarlyView.
Integration of the evolutionary history with distribution of extant species is necessary to explain present‐day diversity, particularly for ‘foundation' species, such as seagrasses, which create habitats of socioecological relevance. Here, we resolved if varying evolutionary history of seagrass families has imprinted the distribution ranges of extant ...

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.

The relationship between aquatic macrophytes and water quality in Nta-Wogba Stream, Port Harcourt, Nigeria [PDF]

, 2011
An empirical survey of macrophytes distribution and biomass from four stations, along Nta-wogba stream in Port Harcourt, Nigeria, was conducted between April and December 2007, to quantify the relationship between biomass, in stream nutrients and ...
