Nature of Phytoplankton Communities in the Southern Hemisphere Shallow Lakes, With an Emphasis on the Presence of Submerged Aquatic Vegetation: A Review

Aquaculture, Fish and Fisheries, Volume 5, Issue 3, June 2025.
ABSTRACT Differences in the ecological stability of shallow lakes are reflected in the functional nature of the distinct phytoplankton communities in the Southern Hemisphere. Recent studies have highlighted growing uncertainties of the previous concepts regarding phytoplankton cosmopolitanism, suggesting these communities may be more regionally ...

Microbial Communities Drive Methane Fluxes From Floodplain Lakes—A Hydrological Gradient Perspective

Environmental Microbiology, Volume 27, Issue 6, June 2025.
This study examined the impact of methanotrophic bacteria (MOB) and methanogenic archaea (mGen) on CH4 emissions from oxbow lakes at various successional stages, analysing their interactions with physicochemical properties of water. The microbial structure, defined by the MOB/mGen ratio, shows emission rates of CH4 specific to each oxbow type.

Facilitation of Lake Eutrophication by Altered Feedback Loops Between Submerged Macrophyte Vegetation and Phosphorus Retention

Freshwater Biology, Volume 70, Issue 5, May 2025.
ABSTRACT Charophytes (stoneworts) often dominate the submerged vegetation in nutrient‐poor hardwater lakes, where they support high benthic phosphorus (P) retention. As a consequence, epilimnion P concentrations remain low and water clarity high, resulting in a positive feedback.

Gadolinium‐Based Contrast Agents (GBCAs) for MRI: A Benefit–Risk Balance Analysis from a Chemical, Biomedical, and Environmental Point of View

Global Challenges, Volume 9, Issue 3, March 2025.
Gadolinium‐based contrast agents (GBCAs) revolutionize magnetic resonance imaging diagnostics but pose challenges due to their environmental impact and potential health risks. This article explores the chemistry, biomedical applications, and ecological concerns of GBCAs, proposing innovative strategies to mitigate these issues, including dose reduction,

Nickel Removal by the Aquatic Plant (Ceratophyllum Demersum L.)

International Journal of Environmental Science and Development, 2012
Phytoremediation with aquatic plants is a new, effective and inexpensive method for improving water quality and wastewater. In this study, Nickel removal by the aquatic plant, coontail (Ceratophyllum demersum L.), native hydrophyte of most of Iran's rivers, was reviewed after optimum growing pH nomination, within 14 days cultivation in contaminated ...

Ceratophyllum demersum a Free-floating Aquatic Plant: A Review

Indian Journal of Pharmaceutical and Biological Research, 2018
Ceratophyllum demersum is a submerged perennial macrophyte normally grow with the base of its stem buried in sandy or silty substrates. It is typically found floating in stagnant and slow moving water. It is a fragile free-floating underwater rootless, but densely leafy, once a year or continuing freshwater aromatic plant, with leaves so crowded at the
