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

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 ...

Potential effects of mechanically removing macrophytes on the phytoplankton community of a subtropical reservoir

Acta Botânica Brasílica, 2018
Intensive growth of aquatic macrophytes interferes with water quality and ecosystem dynamics worldwide. Although mechanically removing macrophytes is the most commonly used method for their eradication, it can also cause undesirable disturbances in ...

Analyzing the effects of four submerged macrophytes with two contrasting architectures on zooplankton: A mesocosm experiment

Journal of Limnology, 2017
Increases in the structural complexity of submerged macrophytes are often shown to be linked to higher invertebrate abundance and diversity, but a number of studies have demonstrated, however, that this is not always the case. The objective of this study

Composition and Functional Diversity of Epiphytic Bacterial and Fungal Communities on Marine Macrophytes in an Intertidal Zone

Frontiers in Microbiology, 2022
Marine macrophytes (seagrasses and macroalgae) and their epiphytic microorganisms play an important role in the ecological and biochemical processes of coastal oceans.

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.

Removing Mn, Cu and Fe from Real Wastewaters with Macrophytes: Reviewing the Relationship between Environmental Factors and Plants’ Uptake Capacity

Toxics, 2023
Heavy metal pollution creates environmental health concerns. Among these, iron (Fe), copper (Cu) and manganese (Mn) are commonly found in aquatic environments due to the release of wastewaters.

Habitat modification by invasive crayfish can facilitate its growth through enhanced food accessibility

BMC Ecology, 2017
Background Invasive ecosystem engineers can facilitate their invasions by modifying the physical environment to improve their own performance, but this positive feedback process has rarely been tested empirically except in sessile organisms. The invasive

Biomass and physiological responses of green algae and diatoms to nutrient availability differ between the presence and absence of macrophytes

Ecological Indicators, 2021
Nutrient enrichment commonly promotes phytoplankton biomass, while the presence of macrophytes can mitigate the promotion effects of nutrient loading. However, the existing studies have seldomly focused on the impacts of macrophytes on the phytoplankton ...

Choosing floating macrophytes for ecological intensification of small-scale fish farming in tropical areas: a methodological approach

Aquatic Living Resources, 2018
Several ecological services and functions are attributed to macrophytes, which may represent valuable resource for the ecological intensification of tropical fish farming.
