The effects of habitat complexity on periphyton biomass accumulation and taxonomic structure during colonization

Warming Effects on Periphyton Community and Abundance in Different Seasons Are Influenced by Nutrient State and Plant Type: A Shallow Lake Mesocosm Study

“…Habitat structure complexity, here expressed as the architecture and morphological characteristics of the host that provides attachment sites for periphyton, can influence the establishment and development of periphyton (Morin, 1986;Gosselain et al, 2005;Casartelli and Ferragut, 2018). Numerous studies have revealed that high habitat structure complexity leads to high periphyton biomass (Ferreiro et al, 2013;Pettit et al, 2016;Hao et al, 2017;Casartelli and Ferragut, 2018) and significantly affects the taxonomic composition of the periphyton attached to its surface (Blindow, 1987;Tunca et al, 2014;Hao et al, 2017). Hao et al (2017) studied periphyton communities on natural and artificial macrophytes (plastic imitations of similar size and morphology as the real plants) with contrasting morphological structures during winter and found that although the periphyton composition differed significantly between the natural and artificial macrophytes, periphyton chlorophyll a (Chla) was positively related to their structural complexity.…”

Succession and Driving Factors of Periphytic Community in the Middle Route Project of South-to-North Water Division (Henan, China)

“…The periphyton community of the canal was similar to that of the Danjiangkou Reservoir [ 30 ], indicating that the delivery of water from the Danjiangkou Reservoir was also an important factor affecting the structure of the algal community. The regular pattern of periphyton community establishment was as follows: (i) particles or dissolved organic substances are electrostatically adsorbed on the substrate, (ii) bacteria grow, providing conditions for other organisms to attach and grow, (iii) pinnate diatoms are adsorbed on the parent substrate, (iv) upright, short-stemmed, or long-stemmed algae are rosetted or mucilaginous on the substrate, and (v) upright filamentous algae are attached [ 31 , 32 ]. Both Cyanobacteria and eukaryotic algae were present in the Henan section of the MRP, and some filamentous algae were common ( Table 2 ).…”

Snail communities increase submerged macrophyte growth by grazing epiphytic algae and phytoplankton in a mesocosm experiment

“…The relationship between producers (e.g., macrophytes, phytoplankton and epiphytic algae) and snails is important in maintaining the function and stability of shallow‐water ecosystems (Jeppesen et al, 1998 ; Kuiper et al, 2017 ; Scheffer, 1999 ; Underwood et al, 1992 ; Yang et al, 2020 ). Submerged macrophytes inhibit epiphytic algae and phytoplankton through the reduction of nutrients, allelopathy and shading (Casartelli & Ferragut, 2018 ; Hilta & Grossb, 2008 ; Mohamed & Shehri, 2010 ; Sand‐Jensen & Borum, 1991 ). Submerged macrophytes also represent an important food source and critical habitats for aquatic animals (Brix, 1994 ; Zhi et al, 2020 ).…”
