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

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

Knowledge and Management of Aquatic Ecosystems, 2020 Transplantation of submerged macrophytes has been widely used to improve water quality in restoring shallow lakes in China. However, in some lakes, small omnivorous fish predominated the fish assemblages and fed mainly on submerged macrophytes.

Variability response of aquatic macrophytes in inland lakes: A case study of Lake Nasser
Egyptian Journal of Aquatic Research, 2021 Aquatic macrophytes are plants that live in water or wet soil, grow profusely in lakes and waterways, and provide several ecological benefits. Lake Nasser, an artificial reservoir, has been the most critical element in Egypt’s social and economic ...

Local ciliate communities associated with aquatic macrophytes [PDF]
, 2014 This study, based within the catchment area of the River Frome, an important chalk stream in the south of England, compared ciliated protozoan communities associated with three species of aquatic macrophyte common to lotic habitats: Ranunculus ...

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.

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

Effects of aquatic vegetation type on denitrification [PDF]
In a microcosm 15N enrichment experiment we tested the effect of floating vegetation (Lemna sp.) and submerged vegetation (Elodea nuttallii) on denitrification rates, and compared it to systems without macrophytes.

Large emissions from floodplain trees close the Amazon methane budget [PDF]
, 2017 Wetlands are the largest global source of atmospheric methane (CH4), a potent greenhouse gas. However, methane emission inventories from the Amazon floodplain, the largest natural geographic source of CH4 in the tropics, consistently underestimate the ...
