Distribution and attachment characteristics of Sida crystallina (O.F. Müller, 1776) in lentic freshwater ecosystems of South Korea
Background: Macrophytes are commonly utilised as habitat by epiphytic species; thus, complex macrophyte structures can support high diversities and abundances of epiphytic species. We tested the hypothesis that the presence of aquatic macrophytes is an important factor determining Sida crystallina (O.F. Müller, 1776) distribution. Results: An ecological survey was conducted in 147 lentic freshw...
متن کاملEffects of Macrophyte Vallisneria asiatica Biomasses on the Algae Community
To improve the water quality of lakes and control algae blooms, the effects of Vallisneria asiatica which is one of aquatic plants spread over Lake Taihu, with different biomasses on the water quality and algae communities were researched. The results indicated that V. asiatica could control an excess of Microcystis spp. when the V. asiatica biomass was larger than 50g in the tank with 30L solu...
متن کاملFunctional diversity of mesograzers in an eelgrass–epiphyte system
Historically, small invertebrate grazers in marine plant communities have been considered to be a relatively homogeneous group in their impact on ecosystem processes. However, recent studies propose that species composition is an important agent in determining grazer effects. We used four mesocosm experiments to test the biomass-specific and density-dependent effects of common mesograzers in te...
متن کاملEffects of grass shrimp versus nutrient addition on epiphytic algae associated with the ephemeral widgeongrass Ruppia maritima
Grazers can reduce epiphytic algal loads on submerged aquatic vegetation (SAV) and indirectly alter biotic interactions among epiphytic algal groups. In the present study, we elucidate responses by 3 major epiphytic functional groups (diatoms, rhodophytes, and chlorophytes) to grass shrimp Palaemonetes spp. addition and nutrient addition during 3 growth stages of the ephemeral estuarine SAV, Ru...
متن کاملSeasonal variation in carbon sources of mesograzers and small predators in an eelgrass community: stable isotope and fatty acid analyses
We assessed the seasonal change in trophic interactions at the mesograzer and small predator level in a temperate eelgrass system. This was done through stable isotope (δ13C and δ15N) and fatty acid analyses of eelgrass Zostera marina, attached epiphytes, sand microflora, the red alga Delesseria sanguinea, and the 4 most common mesograzer and predator species. Sampling took place monthly in the...
