Species composition and morpho-ecological groups of aquatic macrophytes in foothill lakes on the eastern slope of the Southern Urals (Chelyabinsk region, Russia) [PDF]

Check List, 2015
The aquatic macrophyte richness in nine lakes situated in the Chelyabinsk region (Russia) was analyzed. These lakes represent the foothill group, located on the eastern slope of the Southern Urals range.

Effects of turbidity and introduced tilapia (Oreochromis spp) on macrophytes and invertebrates in a shallow tropical lake

Knowledge and Management of Aquatic Ecosystems, 2023
Tropical freshwater wetlands are subject to multiple stressors but there is little information on which stressors cause wetland degradation. Increased turbidity is considered a major cause of degradation, but the effects of introduced fish are often ...

Dragonfly taxonomic and functional responses to urbanized streams in southeastern Europe, with management recommendations

Insect Conservation and Diversity, EarlyView.
Urbanization drives turnover in dragonfly species composition, traits, and habitat conservation value. Natural stream sections have a higher conservation value (higher DBI) due to presence of specialists. Properly managed urban streams can support diverse dragonfly assemblages.

Points vs. passes: A comparison between electric fishing techniques for sampling fish populations in upland headwater streams

Journal of Fish Biology, EarlyView.
Abstract Point‐abundance sampling by electric fishing (PASE) was compared with single‐pass (DF1) and triple‐pass depletion sampling (DF3) electric fishing on the same reaches of four headwater streams sampled over multiple years in the Ribble catchment, UK. Juvenile salmonids, mostly brown trout Salmo trutta with some Atlantic salmon S.

Effects of ammonium pulse on the growth of three submerged macrophytes

PLOS ONE, 2019
Ammonium pulse attributed to runoff of urban surface and agriculture following heavy rain is common in inland aquatic systems and can cause profoundly effects on the growth of macrophytes, especially when combined with low light. In this study, three patterns of NH4-N pulse (differing in magnitude and frequency) were applied to examine their effects on

Phosphorus loading and carp disturbance synergistically promote dominance of free-floating macrophytes over submerged plant competitors

Ecological Indicators
Freshwater ecosystems increasingly face free-floating macrophyte invasions, which suppress submerged vegetation and phytoplankton, threatening biodiversity and ecosystem functions.

Investigation on the trends and characteristics of articles on submerged macrophytes: perception from bibliometrics between 1991 and 2018

Journal of Freshwater Ecology, 2019
Submerged macrophytes, as one of the most important primary producers in shallow lakes and streams, have attracted significant research attention, with relevant studies showing dynamic evolution over the past three decades.

Submerged macrophytes mitigate direct and indirect insecticide effects in freshwater communities. [PDF]

PLoS ONE, 2015
Understanding how ecological interactions mitigate the impacts of perturbations such as pesticides in biological communities is an important basic and applied question for ecologists.

Restoration and rehabilitation of floodplain wetlands: a systematic, global review of restoration options and their outcomes

Restoration Ecology, EarlyView.
Abstract Introduction Floodplain wetlands are vitally important, highly productive, and biodiverse ecosystems. Species dependent on them are facing a range of threats including water extraction, habitat degradation, invasive species, and shifting climates.

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,
