Trophic relationships between primary producers and associated fauna in a pristine Cerrado pond

Journal of Limnology, 2019
Ponds arising from groundwater in Cerrado of Central Brazil are oligotrophic but highly biodiverse environments. In this study, we used stable isotope ratios to test if there are variations in carbon and nitrogen acquisition by different primary food ...

Changes in food‐web pathways and ecosystem functions after sidearm re‐connection in a large river (Danube, Austria)

Restoration Ecology, EarlyView.
Abstract Introduction River regulation schemes generally led to changes in riverine assemblage composition and their trophic status, which often is reflected in a general loss or decrease of characteristic species and a concomitant increase or dominance of generalist species.

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,

Lessons learned from a co‐produced field experiment comparing aquatic vegetation removal methods in recreational waters

Ecological Solutions and Evidence, Volume 7, Issue 3, July–September 2026.
We brought together academic researchers, environmental practitioners and local community members to implement a co‐produced experimental aquatic plant removal. We applied six key lessons learned based on existing co‐production research and added lessons learned from this case study. Overall, we found that building on existing relationships, appointing

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 ...

Effect of Light Intensity on the Production of Volatile Organic Compounds by Submerged Macrophyte Vallisneria natans in Different Growth Periods

Ecology and Evolution, Volume 16, Issue 7, July 2026.
In this study, we investigated the effects of growth period and light intensity on BVOCs production in the submerged macrophyte V. natans using a controlled experiment with three light treatments. The results showed that BVOCs production in submerged macrophytes is jointly regulated by plant growth cycles and underwater light intensities and cannot be ...

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.

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 ...

Abundant interactions and feedbacks between aquatic deoxygenation and the other planetary boundaries suggest “unsafe” levels of oxygen loss with far‐reaching impacts

Limnology and Oceanography, Volume 71, Issue 7, July 2026.
Abstract Oxygen is critical for nearly all life on Earth, including aquatic species that breathe dissolved oxygen in both freshwater and marine systems. The rapid, global, and anthropogenic loss of dissolved oxygen known as “aquatic deoxygenation” threatens life in these environments, the human communities that depend on them, and Earth system ...
