Potential uptake of dissolved organic matter by seagrasses and macroalgae [PDF]
Dissolved organic nitrogen (DON) acts as a large reservoir of fixed nitrogen. Whereas DON utilization is common in the microbial community, little is known about utilization by macrophytes.

Root functional diversity of submerged vegetation exerts a major effect on nitrogen (N) cycling in lake sediments. This fact, however, is neglected in current N‐balance models because the links between the engineering role of plants and in situ microbial

Zooplankton diversity and macrophyte biometry in shallow water bodies of various trophic state
In order to determine whether using indicators of zooplankton diversity and macrophyte parameters (density and biomass) could be a useful tool for diagnosing the water quality of ponds we hypothesised that in various trophic types of shallow water bodies

Herbivory on freshwater macrophytes
Abstract Conventional wisdom holds that live macrophytes are rarely consumed and are functionally unimportant in aquatic food webs. With a review of the literature, I first demonstrate that macrophyte biomass, productivity, and species composition is often influenced by a variety of vertebrate and invertebrate grazers.

Inhibition of cosmopolitan toxic diatom, Pseudo‐nitzschia, by seaweeds
Abstract Pseudo‐nitzschia is a genus of harmful algal bloom (HAB)‐forming diatoms that can produce domoic acid (DA), a compound known to cause death and disease in marine wildlife as well as amnesic shellfish poisoning in humans. Here, we show the effects of multiple cultivable seaweeds—Saccharina latissima (sugar kelp), Ulva spp., and Gracilaria spp ...

The role of surface water waves on cyanobacterial blooms in lakes
Abstract The biophysical processes by which wind‐driven surface waves influence cyanobacterial bloom formation, transport, aerosolization, and termination in lakes represent a major knowledge gap in our understanding of bloom dynamics. We synthesized the literature that examined how waves interact with cyanobacterial bloom processes including ...

Does Long-Term Macrophyte Management in Lakes Affect Biotic Richness and Diversity? [PDF]
We hypothesize that the richness and diversity of the biota in Lake Moraine (42°50’47”N, 75°31’39”W) in New York have been negatively impacted by 60 years of macrophyte and algae management to control Eurasian watermilfoil ( Myriophyllum spicatum L.

Seasonal biodiversity and ecological studies on the epiphytic microalgae communities in polluted and unpolluted aquatic ecosystem at Assiut, Egypt [PDF]
A qualitative and quantitative study on epiphytic microalgae was carried out seasonally from November 2015 to August 2016 to follow up their community structures on aquatic macrophytes related to some physico-chemical properties of two polluted

Bioaccumulation of nickel by aquatic macrophytes
Aquatic plants are being used successfully for the accumulation of trace elements in natural and constructed wetlands. Four aquatic plants were examined for their ability to remove heavy metals from contaminated water. In our study, bioaccumulation abilities of Lemna, Apium, Ceratophyllum and Groenlandia species were found.
