“…The time to attain peak periphyton biomass varied from 23 to 30 days depending on the water resources. Similar studies have reported that the time to achieve peak periphyton biomass was approximately 30 days [4,19]. Compared with the biomass of the HR and the BFW, a faster and larger peak periphyton biomass of MW1 resulted due to the higher nutrient concentrations of MW1 under identical light intensity and water velocity conditions.…”

Abstract:To evaluate the effects of water velocity and artificial substratum characteristics on the growth rate and biomass accumulation of periphyton, an artificial stream mesocosm experiment was conducted using alternative water sources collected from the Mangwall Stream (MW), the Han River (HR), and bank filtration water (BFW) from the Han River in the Republic of Korea. The measured concentrations of organic matter and inorganic nutrients in the MW were higher than in the HR and BFW. The surface of tile is relatively smooth and nonporous, whereas the surfaces of concrete and pebble are rough with numerous isolated pores in which filamentous periphyton become immobilized against hydrodynamic shear stress and mat tensile strength. Compared with the periphyton biomass of the HR and BFW, the peak biomass in the MW was significantly higher due to higher nutrient concentrations in the MW. Reasonable linear relationships (R 2 ≥ 0.69) between water velocity and total periphyton biomass/growth rate were obtained, indicating that water velocities above critical values can cause a reduction in biomass accrual. In addition, reasonable relationships (R 2 ≥ 0.58) between specific surface area and total periphyton biomass were obtained for the HR and BFW, indicating that an increase in the specific OPEN ACCESSWater 2013, 5 1724 surface area of the substratum can lead to an increase in periphyton biomass in a nutrient-poor water body. Principal components analysis (PCA) results indicate that nutrient concentrations were the first dominant limiting factor for the growth and accumulation of periphyton, and water velocity and the specific surface area of the substratum were determined to be potential limiting factors. Consequently, the growth rate and biomass accumulation of periphyton were considered to be a complex function of nutrient concentrations, water velocities, and substratum characteristics.

“…Periphyton have been reported to attach to various substrata and to form various types of biofilm [4,5]. Because periphyton can remain attached to various substrata for an extensive period, they can be used as a biological indicator to evaluate water quality by monitoring changes in biomass or species composition [6,7].…”

“…No reservatório do presente estudo, o pico de biomassa algal em P. repens foi cerca de 6 a 14 vezes maior do que o registrado em Nymphaea sp., Utricularia foliosa e Eleocharis acutangula (Pellegrini & Ferragut 2012;Camargo & Ferragut 2013;Santos et al 2013). Recentemente, Rodusky et al (2013) relataram, com base em 2 anos de estudo, que Panicum, considerada exótica no Lago Okeechobee (Flórida), acumulava muito mais biomassa perifítica do que a nativa Eleocharis celulosa.…”

“…elegans foi a espécie de maior densidade e frequência de ocorrência. Esta espécie é comumente citada como descritora no perifíton nos reservatórios rasos da área de estudo (Vercellino & Bicudo 2006;Santos et al 2013), sendo associada a alta disponibilidade de P na primavera (Fermino et al 2011). De modo geral, as crisofíceas são excelentes competidoras, pois são oportunistas e capazes de alternar processos de autotrofia, heterotrofia e fagotrofia em respostas à condições ambientais (Sandgreen 1988).…”

Este estudo avaliou a estrutura da comunidade de algas perifíticas em Panicum repens em pontos pluriespecíficos de macrófitas em reservatório raso (Lago das Ninféias, São Paulo, Brasil). O objetivo foi avaliar as mudanças na biomassa, abundância e composição espécies, bem como identificar as variáveis ambientais mais relacionadas à variação dos atributos estruturais da comunidade. Pontos de amostragem com a presença de três e quatro espécies de macrófitas (n=3) foram selecionados aleatoriamente (04/2010, 06/2010, 11/2010, 02/2011 AbstractThis study evaluated the periphytic algal community structure on Panicum repens at macrophytes pluriespecifics sites in shallow reservoir (Ninféias Reservoir, São Paulo, Brazil). The aim was to evaluate changes in species composition and abundance, as well as identify the environmental factors most related to the variation of the periphyton structural attributes. Sampling sites with presence of three and four macrophytes species (n = 3) were randomly selected in seasons (04/2010, 06/2010, 11/2010, 02/2011). Climate and water variables, cover macrophyte and periphyton structural attributes were analyzed. Bacillariophyceae and Chrysophyceae were the most abundant algal class and Frustulia crassinervia and Chromulina elegans were the most representative species. The highest biomass and algal density and the lowest autotrophic index were found in summer, showing the further development of the algal community. Our results showed that changes in the periphyton structure on P. repens were determined primarily by seasonality. We conclude that periphyton abundance, biomass and composition changed greatly between the seasons and the light and nutrients availability, particularly phosphorus, were the variables most associated with the community structural changes during the study period. Key words: biomass, periphyton, species composition, algal density, perifíton.Variação sazonal da estrutura da comunidade de algas perifíticas em Panicum repens em um reservatório raso Seasonal variation in the periphytic algal community structure on Panicum repens in a shallow reservoir

“…As macrófitas enraizadas podem funcionar como uma bomba, retirando nutrientes do sedimento e disponibilizando para o perifíton (Wetzel 2001). A arquitetura e a forma biológica da macrófita também pode determinar a estruturação da comunidade perifítica, pois atuam diretamente sobre a disponibilidade de luz (sombreamento) e de área de colonização (Cattaneo et al 1998, Santos et al 2013. As macrófitas também podem influenciar negativamente a estrutura da comunidade perifítica por meio da liberação de substâncias alelopáticas (Erhard & Gross 2006).…”

Estrutura da comunidade de algas perifíticas emABSTRACT -(Periphytic algal community structure on Eleocharis acutangula (Roxb.) Schult (Cyperaceae) in a tropical shallow reservoir, São Paulo, São Paulo State, Brazil). The aim of this study was to evaluate the influence of seasonal variation of environmental conditions on the structural attributes of the periphyton community on Eleocharis acutangula (Roxb.) Schult (Cyperaceae) in the littoral zone of Ninféias Lake, São Paulo, São Paulo State, Brazil. The spring and summer were characterized by higher values of macrophyte cover, phytoplankton chlorophyll a, light, and phosphorus availability in the water. Periphyton biomass and algal density were negatively correlated with macrophyte cover and phytoplankton chlorophyll a. The species composition, algal classes, and descriptors changed in seasonal scale. We concluded that periphyton community structure on Eleocharis acutangula was strongly influenced by macrophyte cover and phytoplankton biomass. Availability of nutrientsin the water seems to play a minor role in community organization. The responses of the structural attributes of the periphyton showed a strong interrelationship with macrophytes and phytoplankton, which should be better understood in shallow tropical reservoirs.
