Growth rate, protein:RNA ratio and stoichiometric homeostasis of submerged macrophytes under eutrophication stress

Knowledge and Management of Aquatic Ecosystems, 2016
Growth rate hypothesis (GRH) and stoichiometric homeostasis of photoautotrophs have always been questioned. However, little is known about GRH and stoichiometric homeostasis of aquatic plants, especially submerged macrophytes ...

Structure of epiphyton communities on Lake Baikal submerged macrophytes [PDF]

Limnological Review, 2012
Abstract We carried out a first study of Lake Baikal epiphyton on six species of submerged macrophytes: Myriophyllum spicatum L., Potamogeton perfoliatus L., Potamogeton sp., Sparganium gramineum Georgi, Ceratophyllum demersum L., and Elodea сanadensis Michaux.

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

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.

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.

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

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.

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 ...

A Multi‐Method Approach to Assessing Barrier Effectiveness in Preventing the Spread of Invasive Signal Crayfish (Pacifastacus leniusculus)

River Research and Applications, EarlyView.
ABSTRACT Relieving barriers and increasing free flowing rivers is a global imperative to restore habitat connectivity for migratory fish stocks. While reducing river fragmentation will certainly improve biodiversity, the spread of non‐native species throughout a river system may be facilitated as an inadvertent outcome.

Environmental Stressors Influence Spatial Complexity in a Fluvial Macrophyte meadow

Remote Sensing in Ecology and Conservation, EarlyView.
This research investigates the nonlinear relationships between environmental stressors and the fine‐scale spatial complexity of a fluvial macrophytes meadow. The use of multivariate spatial analysis allowed us to identify two major environmental gradients (nutrients and light) and two major complexity gradients (related to abundance and fragmentation).
