Effect of Hirschmanniella caudacrena on the Submersed Aquatic Plants Ceratophyllum demersum and Hydrilla verticillata.

Journal of nematology, 2011
In vitro pathogenicity tests demonstrated that Hirschmanniella caudacrena is pathogenic to Ceratophyllum demersum (coontail). Symptoms were chlorotic tissue, deformed stems, and, finally, death of the plant. Inoculum densities of 500 nematodes per 5-cm-long cutting in a test tube containing 50 ml of water resulted in death and decay of some of the ...

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,

Rising Water Levels and Vegetation Shifts Drive Substantial Reductions in Methane Emissions and Carbon Dioxide Uptake in a Great Lakes Coastal Freshwater Wetland

Global Change Biology, Volume 31, Issue 2, February 2025.
Coastal freshwater wetlands are dynamic ecosystems located at the interface between land and lakes. These wetlands are among the largest natural sources of methane, yet their response to changes in hydrology, such as lake water levels, remains poorly understood.

Effects of water regime on the growth of the submerged macrophyte Ceratophyllum demersum at different densities

Journal of Freshwater Ecology, 2018
To successfully restore deteriorated lake ecosystems, it is vital to identify influencing environmental factors that impact submerged macrophytes. Planting density and water regime are important factors for submerged macrophytes’ growth.

Aquatic Plant Surveys in the Bureau of Land Management, Medford District, 2010-2011 [PDF]

, 2011
The introduction of invasive aquatic plant species (IAPS) can cause significant ecological and economic harm. IAPS can displace native aquatic plant species, impair recreation, and degrade water quality.

Submerged Macrophytes Can Maintain Stable Dominance Over Free‐Floating Competitors Through High pH

Freshwater Biology, Volume 70, Issue 1, January 2025.
ABSTRACT Submerged and free‐floating macrophytes are the two main vegetation types that can alternatively dominate in small shallow ponds and ditches. Submerged macrophytes provide more aquatic ecosystem services and cause fewer problems with anoxia and greenhouse gas emissions than free‐floating plants, but are inferior competitors for light.

Native and non-native plants provide similar refuge to invertebrate prey, but less than artificial plants.

PLoS ONE, 2015
Non-native species introductions are widespread and can affect ecosystem functioning by altering the structure of food webs. Invading plants often modify habitat structure, which may affect the suitability of vegetation as refuge and could thus impact ...
