Repérer les macrophytes depuis le ciel ou sous les eaux, quel appui pour les gestionnaires ?
Que ce soit pour la connaissance ou dans un objectif de gestion, l'étude de la distribution des macrophytes est indispensable. Historiquement tributaire des seules prospections de terrain, l'acquisition de ces données peut aujourd'hui s'appuyer sur de ...

Herbicides for Rooted Aquatic Macrophytes [PDF]
ABSTRACT: The aim of this study was to evaluate the effectiveness of glyphosate, 2,4-D, and diquat to control the aquatic macrophytes Brachiaria subquadripara, Hedychium coronarium, and Myriophyllum aquaticum under greenhouse conditions. The following herbicides and doses were used: glyphosate at 240, 720, 1,680, 2,640, 3,600, and 4,320 g a.e.

Macrophytes as bioindicators [PDF]
Submerged macrophytes respond to changes in the nutrient concentrations in their environment. In contrast to diatoms e.g., submerged macrophytes are capable of taking up nutrients from both the sediment pore water and the overlying water. Therefore, macrophytes can provide a more comprehensive assessment of river ecosystems. Two methods using submerged

Effects of vegetation, season and temperature on removal pollutants in experimental floating treatment wetlands [PDF]
The research and interest towards the use of constructed floating wetlands for (waste)water treatment is emerging as more treatment opportunities are marked out, and the technique is applied more often. To evaluate the effect of a floating macrophyte mat

Investigating periphyton biofilm response to changing phosphorus concentrations in UK rivers using within-river flumes [PDF]
The excessive growth of benthic algal biofilms in UK rivers is a widespread problem, resulting in loss of plant communities and wider ecological damage.

Control of macrophytes by grass carp (ctenopharyngodon idella) in a Waikato drain, New Zealand [PDF]
Hornwort (Ceratophyllum demersum L.) and other aquatic macrophytes have historically been mechanically removed from the Rangiriri drain and Churchill East drain to maintain drain efficiency.

Evidence on Night Movements of Macroinvertebrates to Macrophytes in a Pampean Stream [PDF]
Nocturnal invertebrate abundance peaks in lotic systems are usually associated to drift, however, diel migrations other than drift may be important in slow-flowing systems.

Monitoring Spatial Variability and Temporal Dynamics of Phragmites Using Unmanned Aerial Vehicles
Littoral zones of freshwater lakes are exposed to environmental impacts from both terrestrial and aquatic sides, while substantial anthropogenic pressure also affects the high spatial, and temporal variability of the ecotone.
