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.

Rapid Eutrophication of a Clearwater Lake: Trends and Potential Causes Inferred From Phosphorus Mass Balance Analyses

Global Change Biology, Volume 30, Issue 11, November 2024.
The causes of the rapid eutrophication of a clearwater lake were investigated. A mass balance for phosphorus (P) indicated that sediments in the shallow parts of the lake acted as a net P source for several years. These P losses from the sediments are potentially related to shifts in submerged macrophytes and to increased sulfide formation, promoting ...

Modeling the risk of aquatic species invasion spread through boater movements and river connections

Conservation Biology, Volume 38, Issue 4, August 2024.
Abstract Aquatic invasive species (AIS) are one of the greatest threats to the functioning of aquatic ecosystems worldwide. Once an invasive species has been introduced to a new region, many governments develop management strategies to reduce further spread.

What is the effectiveness of methods for eradicating or controlling abundance and biomass of invasive aquatic plants in Canada? A systematic review protocol

Ecological Solutions and Evidence, Volume 5, Issue 2, April/June 2024.
This protocol sets out the research methodologies for a systematic review examining the effectiveness of control methods (e.g., biological, chemical and physical) for eradicating or controlling invasive aquatic plant species impacting or likely to impact Canadian freshwater systems.

Interactions between stoneworts (Charales) and waterbirds

Biological Reviews, Volume 99, Issue 2, Page 390-408, April 2024.
ABSTRACT Stoneworts (Charales) are green algae that represent an important food resource for many waterbird species in Europe and elsewhere. Browsing avian herbivores (e.g. swan, goose, duck and coot species) consume Charales plant vegetative parts, by head‐dipping, up‐ending or diving.

Recycling and deposition of inorganic carbon from calcium carbonate encrustations of charophytes

Limnology and Oceanography, Volume 69, Issue 2, Page 279-289, February 2024.
Abstract Many aquatic primary producers can use bicarbonates as a carbon source for photosynthesis. Charophytes of the two genera: Chara and Nitellopsis are quite efficient in this process. Some species of these macroalgae produce carbonate encrustations, mainly calcium carbonate, constituting up to 86% of the summer maximum dry weight of the standing ...
