Effects of contrasting omnivorous fish on submerged macrophyte biomass in temperate lakes: a mesocosm experiment [PDF]

, 2012
1.Freshwater fish can affect aquatic vegetation directly by consuming macrophytes or indirectly by changing water quality. However, most fish in the temperate climate zone have an omnivorous diet.

The Future of Freshwater Macrophytes in a Changing World: Dissolved Organic Carbon Quantity and Quality and Its Interactions With Macrophytes

Frontiers in Plant Science, 2018
Freshwater ecosystems are confronted with the effects of climate change. One of the major changes is an increased concentration of aquatic carbon. Macrophytes are important in the aquatic carbon cycle and play as primary producers a crucial role in ...

Early results and lessons learned from biomanipulation and chemical restoration of a eutrophic shallow lake

Restoration Ecology, EarlyView.
Abstract Introduction Over 44% of European lakes fail to meet ecological quality standards, prompting substantial investment in lake restoration to achieve good ecological status. Unfortunately, effects are often short‐lived due to persistent internal phosphorus (P) loading and strong cyprinid‐driven bottom‐up control, which limits water quality ...

Effects of a nonnative species of Poaceae on aquatic macrophyte community composition: A comparison with a native species

, 2015
Invader-dominated systems of exotic species frequently damage native communities, mainly because there is a shift in the competition-facilitation balance, and competition intensifies in communities structured by facilitation.

Sustainable Aquaculture Industry in Kenya: Mapping Inputs for Fish Feed, Constraints, and Opportunities for Youth Involvement

Reviews in Aquaculture, Volume 19, Issue 1, January 2027.
The cost of aquafeed continues to constrain aquaculture production amidst the availability of locally available ingredients for feed formulation and technological opportunities. Information dissemination and innovative rethinking on the utilization of local opportunities and youthful labor may spur the growth of the sector, thus improving fish protein.

Can sacrificial feeding areas protect aquatic plants from herbivore grazing? Using behavioural ecology to inform wildlife management [PDF]

, 2014
Effective wildlife management is needed for conservation, economic and human well-being objectives. However, traditional population control methods are frequently ineffective, unpopular with stakeholders, may affect non-target species, and can be both ...

Macrophyte dynamics in Mediterranean rivers: a first insight from the upper Oum Er-Rbia Basin (Middle Atlas, Morocco)

Journal of Freshwater Ecology
Macrophyte dynamics in rivers are expressed through spatiotemporal gradients that reflect the functioning of freshwater ecosystems. In Mediterranean rivers, characterized by irregular low-flow periods and sudden floods, these gradients strongly influence

Downstream Effects of a Hydroelectric Reservoir on Aquatic Plant Assemblages

The Scientific World Journal, 2002
Macrophytes were studied downstream of the Rophémel hydroelectric dam on the River Rance (Côtes d’Armor Department, western France) to assess the effects of hydroelectric functioning on river macrophyte communities. We studied ten representative sections

Freshwater Biodiversity Research in Brazil: Trends from a Systematic Review and Topic Modeling

International Review of Hydrobiology, Volume 111, Issue 2, December 2026.
ABSTRACT Brazil is a megadiverse country that hosts six major biomes and a vast freshwater network. Despite this richness, research on freshwater biodiversity has been heterogeneous across regions, communities, and time, leaving significant knowledge gaps.

Long-term variations in fish assemblage, macrophyte community, and water quality in Lake Rotoroa (Hamilton Lake) [PDF]

, 2012
Lake Rotoroa (37º48’S, 175º16’E) is a small, shallow, polymictic lake located on the western side of Hamilton City. The lake covers an area of 0.54 km2 with a mean depth of 2.4 m, catchment and riparian margins have been significantly modified into a ...
