Invasive Macrophytes Control the Spatial and Temporal Patterns of Temperature and Dissolved Oxygen in a Shallow Lake: A Proposed Feedback Mechanism of Macrophyte Loss

open access: yesFrontiers in Plant Science, 2017
Submerged macrophytes can have a profound effect on shallow lake ecosystems through their ability to modify the thermal structure and dissolved oxygen levels within the lake.

THE PERMISSIBLE INPUT OF BIOGENIC ELEMENTS TO WATER BODIES WITH SLOWED AND MODERATE WATER EXCHANGE

open access: yesВодное хозяйство России: проблемы, технологии, управление, 2020
The article presents the outputs of researches on determination of permissible input of biogenic matter to water bodies with different types of moderate and slowed water exchange: that is phytoplankton, phytoplankton/macrophyte, and macrophyte types. We

Les macrophytes sont-ils de bons candidats pour l'évaluation du succès d'une restauration ? L'exemple des anciens bras du Rhin reconnectés

open access: yesSciences, Eaux & Territoires, 2014
Des opérations de restauration dans la plaine d'Alsace ont conduit à reconnecter d'anciens bras latéraux du Rhin au cours principal. Les communautés végétales aquatiques sont utilisées comme indicateurs du succès de l'opération. Afin de tester cet outil,

Efficient sampling methodologies for lake littoral invertebrates in compliance with the European Water Framework Directive [PDF]

open access: yes, 2015
Lake shores are characterised by a high natural variability, which is increasingly threatened by a multitude of anthropogenic disturbances including morphological alterations to the littoral zone. The European Water Framework Directive (EU WFD) calls for

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

open access: yesSciences, 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.

Nutrient pulse scenarios drive contrasting patterns in the functional stability of freshwater phytoplankton

open access: yesLimnology and Oceanography, EarlyView.
Abstract Climate change is increasing the frequency, intensity, and stochasticity of extreme weather events such as heavy rainfall, storm‐induced mixing, or prolonged drought periods. This results in more variable regimes of dissolved nutrients and carbon in lakes and induces temporal fluctuations in the resource availability for plankton communities ...

Linking macrophyte community structure with food chain length: A case study in the largest freshwater lake in China and ecological restoration implications

open access: yesEcological Indicators, 2021
Food chain length is a significant ecosystem index and it greatly affects ecosystem processes and their outcomes. In recent decades, determinants or indicators of FCL have been investigated in different ecological contexts, but few studies analyzed the ...

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

open access: yesSciences, 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 ...

Small‐scale thermal habitat variability may not determine seagrass resilience to climate change

open access: yesLimnology and Oceanography, EarlyView.
Abstract Seagrass ecosystems are integral components of coastal marine environments, but they face global threats from climate change. The ability of seagrass to withstand these challenges depends on trait variation among individuals, which is influenced by genetic background and plasticity.

Note – Gestion des Jussies dans le Marais Poitevin

open access: yesSciences, 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.
