Hydrologic, Plant and Soil Controls on Microbial Biomass and Enzyme Activities in a Natural and a Restored Freshwater Marsh of Eastern Ontario, Canada

Freshwater Biology, Volume 71, Issue 10, October 2026.
ABSTRACT The hydrology and drainage history of freshwater marshes influence their soil properties and plant communities, which in turn affect microbial biomass and extracellular enzyme activities that regulate the biogeochemistry and functioning of the marsh. However, field reports examining the spatial differences and controls of microbial biomass and

Integrating water depth to predict the threshold of collapse and recovery of submerged macrophytes for lakes with large depth gradients

Frontiers in Plant Science
IntroductionThe nutrient threshold of collapse and recovery of submerged macrophytes have been widely reported for shallow lakes. However, understanding the threshold variation for lakes with water depth (Z) gradients remains limited.MethodsIn this study,

Organic‐matter sources and stability in kettle‐hole sediments: A combined thermogravimetric and isotopic approach

Agrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.
Abstract Kettle‐holes are small but biogeochemically active landscape elements that integrate terrestrial inputs and influence carbon and nitrogen cycling. However, the stability and sources of organic matter (OM) in kettle‐hole sediments remain poorly understood.

The effects of nutrient level on periphyton–macrophyte interactions in freshwater ecosystems

Water Biology and Security
Periphyton are one of the key primary producers in aquatic ecosystems, particularly in oligotrophic shallow lakes. Submerged macrophytes are capable of competing with periphyton for nutrients and light, but may also facilitate periphyton by providing ...

Influence of submerged macrophytes on phosphorus in a eutrophic reservoir in a semiarid region

Journal of Limnology, 2020
Phosphorus (P) is the main nutrient responsible for the harmful effects caused by the enrichment of aquatic systems, and submerged macrophytes play an important role in this process, since they can both remove and release this nutrient in environmental ...

Exploring the Geodiversity—Biodiversity Relationships in Freshwaters for Environmental Conservation: A Global Systematic Literature Review

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 9, September 2026.
ABSTRACT Geodiversity refers to the heterogeneity of abiotic characteristics in nature, and in freshwater ecosystems, it mostly mirrors the diversity of hydro‐geomorphological features in inland waters. Although several scholars have highlighted that geodiversity contributes to habitat formation and influences biodiversity and ecological processes, it ...

Simple relationships to predict attributes of fish assemblages in patches of submerged macrophytes

Neotropical Ichthyology
Submerged macrophytes play an important role in structuring habitats and, therefore, in determining patterns of aquatic biodiversity. Because these plants are widespread in shallow areas of many Neotropical reservoirs, the present work investigated if ...

Leachates and elemental ratios of macrophytes and benthic algae of an Andean high altitude wetland

Journal of Limnology, 2011
In wetlands, macrophytes and filamentous algae constitute an important carbon source for the total content of Dissolved Organic Matter (DOM) of the environment.

Contrasting Temporal Dynamics of Ostracod (Crustacea) Communities in Protected and Impacted Areas in a Brazilian Floodplain

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 9, September 2026.
ABSTRACT Environmental integrity is vital for the long‐term preservation of freshwater biodiversity, which is currently among the most threatened on Earth due to anthropogenic pressures such as dam construction. The present study investigated the temporal responses of ostracod communities over 8 years (2017–2024) in the Upper Paraná River floodplain ...

Vertical optical complexity shaped by submerged macrophytes

Scientific Reports
AbstractThe influence of macrophytes on the optical environment of the littoral zone was assessed by studying the effect of monospecific Potamogeton perfoliatus on the quantitative and qualitative properties of light and the response of plants to this altered environment. P.
