“…In rocky shores, the strong dominance of diatoms and the high Si:N and Si:P ratios in macroalgae tissues can account for Si accumulation, exceeding N and especially P uptake, despite a lower plant biomass [23,[70][71][72]. We found that the P content in epilithic biomass was close to or below the lower limit of the optimal range for growth (0.01-0.02%) reported for epilithic primary producers [73][74][75][76].…”

Benthic vegetation at the land-water interface is recognized as a filter for silica fluxes, which represents an important but under-investigated subject. This paper aims to analyze stocks and fluxes of biogenic (BSi) and dissolved (DSi) silica in relation to nitrogen (N) and phosphorus (P) in the littoral zone of a deep lake. Specifically, we evaluated how different primary producers can influence BSi retention and DSi release. The study was performed from April to October in 2017, in three different benthic communities: submerged aquatic vegetation (SAV) and microphytobenthos (MPB), both occurring in soft bottom sediments, and epilithic macro- and microalgae (EA) on rocky substrates. The main result was that SAV and MPB were a DSi source and a N and P sink with the DSi efflux from SAV nearly three times as much as in MPB patches. These findings corroborate the hypothesis that SAV mediates the DSi transport from pore water to the water column. Conversely, EA communities were a DSi sink and a N and P source. Overall, these results highlight the fact that the littoral zone of lakes plays a key role in regulating aquatic Si cycling, which is likely to depend on the health status of SAV communities.

“…Glass slides are the most used artificial substrate in ecological studies (Trbojević et al, 2018) since it is inert and has a regular surface. Comparing different substrate types, Cao et al (2019) observed lower pigments concentration and algal richness and diversity in the periphyton on plastic, which had a smooth surface and an unfavorable position. However, in a bioremediation perspective, plastic has some advantages, since it is more resistant, lighter, and cheaper than glass, and more portable than sand or stones.…”

“…Numerous studies have reported that substrate type can strongly influence the development of the periphyton and, consequently, affect community responses to environmental change (e.g. : Zhang et al, 2013;Trbojević et al, 2018, Morashashi et al, 2019, Cao et al, 2019. Glass slides are the most used artificial substrate in ecological studies (Trbojević et al, 2018) since it is inert and has a regular surface.…”

“…However, in a bioremediation perspective, plastic has some advantages, since it is more resistant, lighter, and cheaper than glass, and more portable than sand or stones. Plastic substrates were successfully utilized to periphyton growth previously (Milstein, Peretz and Harpaz, 2009;Cao et al, 2019;Morashashi et al, 2019). Though, the relationship between substrate type and efficiency of periphyton in immobilizing phosphorus and metals needs to be further investigated.…”

Phosphorus and metals immobilization by periphyton in a shallow eutrophic reservoir

et al. 2021

Aim: This study evaluated and compared the changes in the Total Phosphorus (TP) and metals (Cd, Cu, Ni and Pb) contents and accumulation rates in the periphyton on different substrate types (PET and glass) in wet and dry periods in a shallow eutrophic reservoir. Thus, the potential of periphyton as a green biotechnology to remediate the eutrophication and promoting metal uptake were investigated. Methods: Floating substrate carriers made of wood (n = 3) containing glass and PET slides were submerged close to a sewage inflow site. Substrate exposure time was about 33 days in each period. Results: Periphyton TP and metal contents (Cu, Ni and Pb) were influenced by seasonality and the highest contents were found in the wet period. Periphyton metal contents were significantly different between glass or PET substrates, but no differences were detected in the TP contents. Conclusions: Seasonality was a determining factor for immobilization of TP and metals in periphyton. The highest potential of TP and metals immobilization by periphyton were detected in the wet period. Our results provided insights that the periphyton can contribute to remediate eutrophication and metal removal in aquatic ecosystems.

“…Tavares, Lambrecht, de Almeida Castilho, Henry, and Ferragut (2019) observed that P enrichment in shallow, tropical lakes and reservoirs reduced the photosynthetic potential of the epipelon, which could directly impact interactions between phytoplankton, zooplankton, and epipelon, and ultimately, ecosystem function. Cao, Zhang, Sun, and Li (2019) performed a mesocosm study and found that substrate type (sand, cobble, or plastic) was critical for periphytic pigment content (chlorophyll and pheophytin), nutrient accrual (carbon, N, and P), carbon:chlorophyll ratio, and algal species composition at the end of the experiment. Periphytic nutrient accrual and the carbon:chlorophyll ratio were both higher on sand than on the other two substrates.…”

Highlights of new, interesting, and emerging research findings on substratum-associated microbiota covered from a survey of 2019 literature from primarily freshwaters provide insight into research trends of interest to the Water Environment Federation and others interested in benthic, aquatic environments. Coverage of topics on bottom-associated or attached algae and cyanobacteria, though not comprehensive, includes new methods, taxa new-to-science, nutrient dynamics, auto-and heterotrophic interactions, grazers, bioassessment, herbicides and other pollutants, metal contaminants, and nuisance, and bloom-forming and harmful algae. Coverage of bacteria, also not comprehensive, focuses on the ecology of benthic biofilms and microbial communities, along with the ecology of microbes like Caulobacter crescentus, Rhodobacter, and other freshwater microbial species. Bacterial topics covered also include metagenomics and metatranscriptomics, toxins and pollutants, bacterial pathogens and bacteriophages, and bacterial physiology. Readers may use this literature review to learn about or renew their interest in the recent advances and discoveries regarding substratum-associated microbiota. © 2020 Water Environment Federation • Practitioner points • This review of literature from 2019 on substratum-associated microbiota presents highlights of findings on algae, cyanobacteria, and bacteria from primarily freshwaters. • Coverage of algae and cyanobacteria includes findings on new methods, taxa new to science, nutrient dynamics, auto-and heterotrophic interactions, grazers, bioassessment, herbicides and other pollutants, metal contaminants, and nuisance, bloomforming and harmful algae. • Coverage of bacteria includes findings on ecology of benthic biofilms and microbial communities, the ecology of microbes, metagenomics and metatranscriptomics, toxins and pollutants, bacterial pathogens and bacteriophages, and bacterial physiology. • Highlights of new, noteworthy and emerging topics build on those from 2018 and will be of relevance to the Water Environment Federation and others interested in benthic, aquatic environments
