Effects of Invasive Watermilfoil on Primary Production in Littoral Zones of North-Temperate Lakes
Diversity, 2020 Species invasions are changing aquatic ecosystems worldwide. Submerged aquatic macrophytes control lake ecosystem processes through their direct and indirect interactions with other primary producers, but how these interactions may be altered by ...

Macrophytes as bioindicators [PDF]
River Systems, 2003 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

Utilization of fish gut analysis to elucidation of microcrustacean
Journal of Ecology and Environment, 2014 Structural heterogeneity results in different spatial distributions of microcrustaceans. Thus, in ecosystems with excessive macrophyte development, it may be difficult to determine the microcrustacean species composition.

The relative contribution of aquatic macrophytes and their epiphytes to the production of macrophyte beds1 [PDF]
Limnology and Oceanography, 1980 The epiphyte contribution to the total production of Lake Memphremagog macrophyte beds changed in a predictable fashion with the season, the morphology of the macrophytes, the depth of the bed, and the trophy of the water. In the mesotrophic portion of the lake, epiphytes fixed more carbon than the macrophytes only at the beginning and end of the ...

Herbicides for Rooted Aquatic Macrophytes [PDF]
Planta Daninha, 2019 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.

Every Start is Challenging: Fitting A New Artificial Lake Into the Landscape, Zalakaros, Hungary
Journal of Environmental Geography, 2018 The aim of this study is to conclude the experiences of the maintenance practice of an artificial thermal lake. The first years (2015-2017) of the development of the lake were analysed and evaluated along the following questions: a) What kind of design ...

Repérer les macrophytes depuis le ciel ou sous les eaux, quel appui pour les gestionnaires ?
Sciences, Eaux & Territoires, 2014 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 ...

Journal of Applied Sciences and Environmental Management, 2021 Water hyacinth is one of the aggressive alien aquatic macrophyte threatening biodiversity, economic development and human wellbeing. Currently, the macrophyte has invaded Lake Tana and its catchment causing several socio-ecological impacts.

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 ...
