The Distribution and Production of Submerged Macrophytes in Loch Leven, Kinross [PDF]

Proceedings of the Royal Society of Edinburgh. Section B. Biology, 1974
SynopsisThe distribution and production of submerged macrophytes in Loch Leven has been investigated using drag-rake surveys and biomass measurements. Survey data suggest that changes in the species diversity of the loch have occurred since the earlier records.

Application of UAV Imagery to Detect and Quantify Submerged Filamentous Algae and Rooted Macrophytes in a Non-Wadeable River

Remote Sensing, 2020
Imagery from unoccupied aerial vehicles (UAVs) is useful for mapping floating and emerged primary producers, as well as single taxa of submerged primary producers in shallow, clear lakes and streams. However, there is little research on the effectiveness

Disentangling the mechanisms sustaining a stable state of submerged macrophyte dominance against free-floating competitors

Frontiers in Plant Science, 2022
Free-floating and rootless submerged macrophytes are typical, mutually exclusive vegetation types that can alternatively dominate in stagnant and slow flowing inland water bodies.

Morphological responses to water-level fluctuations of two submerged macrophytes, Myriophyllum spicatum and Hydrilla verticillata [PDF]

, 2013
Myriophyllum spicatum and Hydrilla verticillata are common submerged macrophytes in the Yangtze River basin. To investigate their tolerances and adaptations to water-level fluctuations, an experiment was conducted in a pond.

Do submerged macrophyte species influence crustacean zooplankton functional group richness and their resource use efficiency in the low-light environment?

Frontiers in Plant Science, 2023
During the high grazing of epiphytic zooplankton in submerged macrophyte beds, the changes in crustacean zooplankton functional groups are crucial for stabilizing a clear water state in shallow lakes.

From single to synthetic PGPR: Exploring the strategies of submerged macrophyte remediation in cadmium polluted sediment

International Journal of Sediment Research
Plant growth-promoting rhizobacteria (PGPR) are used to assist phytoremediation. Synthetic PGPR can adapt to diverse sediment environments more effectively than single PGPR. However, their mechanisms of application in submerged macrophytes remediation of

Combined stable isotope and gut contents analysis of food webs in plant-dominated, shallow lakes [PDF]

, 2003
1. To determine feeding links between primary producers, invertebrates and fish, stable isotope analyses and gut content analyses of fish were conducted on the components of four shallow, eutrophic to hypertrophic, plant-dominated lakes. 2.

POLYPHENOLS WITH ALGICIDAL ACTIVITY IN THE SUBMERGED MACROPHYTE MYRIOPHYLLUM SPICATUM L. [PDF]

Acta Horticulturae, 1994
The role of phenols as defence mechanisms in various terrestrial plants is well studied. However, in aquatic environments, they are probably involved also in the chemical interactions between species. A periodic shift from dominance by submerged macrophytes to dominance by phytoplankton and vice versa without apparent change in the external nutrient ...

Development and Improvement of Habitat Suitability Criteria for Instream Habitat Assessments Conducted in Support of Environmental Flows in Florida

River Research and Applications, EarlyView.
ABSTRACT Florida's regulatory framework requires the establishment of minimum flows to protect aquatic ecosystems and water resources from significant harm. One of the primary methods used to evaluate significant harm is assessment of instream habitat, which relies on Habitat Suitability Criteria (HSC) curves that relate flow regimes and habitat ...

Trace element stoichiometry of submerged macrophytes in Yangtze floodplain lakes and Yunnan plateau lakes (China) [PDF]

, 2017
Trace element balance is a key parameter in ecological stoichiometry. However, little is known about trace element stoichiometry of submerged macrophytes. We hypothesized that lake nutrients (N and P) and taxonomy strongly affect tissue trace element (Al,
