“…The results reported in the literature demonstrated strong affects of habitat structure and architecture of macrophyte leaf or stem on the spatial distribution and taxonomic composition of aquatic organisms (Duggan et al, 2001;Mieczan, 2007;Pals et al, 2006). Macrophytes strongly influence protozoan species composition by modifying protozoan food availability and increasing the spatial heterogeneity (Biyu, 2000).…”

Ciliates on the Macrophytes in Industrially Heated Lakes (Kujawy Lakeland, Poland). Babko R., Fyda J., Kuzmina T., Hutorowicz A. -The ciliate assemblage on the macrophytes was examined in 2005 during the vegetation period in the Koninśkie Lakes which are heating by post-cooling waters from thermal electric plants. As a result of changed temperature regimen the alien thermophilic macrophyte Vallisneria spiralis is becoming increasingly common in the littoral zone. A total of 150 ciliate taxa belonging to 27 orders were found. Greater ciliate species diversity was found on architecturally complex, submerged forms such as Ceratophyllum demersum and Myriophyllum spicatum. By contrast the ciliate compositions on emergent macrophytes with simple architecture in their submerged parts, such as Typha, Sparganium, or Acorus, were less species rich. Despite the simple architecture of Vallisneria leaves, the ciliate diversity on them was high. The results show that replacement of native macrophytes by the alien form V. spiralis in heated lakes did not impoverish the ciliate diversity.K e y w o r d s: ciliate, macrophytes, diversity, lakes.Ðåñíè÷íûå ïðîñòåéøèå íà ìàêðîôèòàõ â îçåðàõ, ïîäâåðaeåííûõ òåïëîâîìó çàãðÿçíåíèþ (îçåðíûé êðàé Êóÿâû, Ïîëüøà).

“…Consequently the number of possible niches offered for a variety of periphytic species is enormous, so differences in species composition and density on different macrophytes are likely to occur (Messyasz, Kuczynśka-Kippen, 2006;Mieczan, 2007;Pals et al, 2006).…”

“…Concerning periphyton community structure on different substrate types, comparative investigations have shown that its attributes may be influenced by natural versus artificial substrates (Cattaneo & Amireault, 1992;Albay & Akcaalan, 2003;Vadeboncoeur et al, 2006;Ferragut et al, 2010), macrophyte architecture (Cattaneo et al, 1998) and surface roughness (Sousa & Ferragut, 2012). Specifically, the few studies on Zygnematophyceae algae available in the literature, which are focused on macrophytes and/or sandy sediments (Pals et al, 2006;Mutinová et al, 2016), have suggested that substrate influence is relatively low and varies with sites.…”

Community structure of periphytic Zygnematophyceae (Streptophyta) in urban eutrophic ponds from central Brazil (Goiânia, GO)

Aim This study aimed to investigate the community structure of Zygnematophyceae algae in the periphyton of nine shallow urban eutrophic ponds from central Brazil. Additionally, we compared two different substrates, hypothesizing that community structure attributes (chlorophyll a; Zygnematophyceae density, composition and richness) would differ between them. Methods Samples were carried out in August 2014. Periphyton was collected from two different substrates, macrophyte (epiphyton) and rocks (epilithon). Results The ponds presented pH ranging from neutral to slightly acidic and electrical conductivity in general higher than 60 µS.cm-1. Zygnematophyceae contributed with 0.82% of total periphyton community density in the epiphyton and 0.02% in the epilithon. Altogether 49 Zygnematophyceae taxa were recorded, distributed in 13 genera. Based on frequency of occurrence, most taxa were classified as rare, being present in less than 25% of the ponds. The taxa with higher densities were Cosmarium regnesii var. regnesii, Cosmarium abbreviatum var. minus, and Mougeotia sp. 3. When each pond was considered individually, other taxa were highlighted as the most abundant among Zygnematophyceae. It was the case of Staurastrum smithii, Cosmarium exiguum, Mougeotia sp. 1 and Mougeotia sp. 2. The two ponds with highest Zygnematophyceae density showed high similarity in the species composition (>70%); however, among the others, it was relatively low (<50%). Conclusions The eutrophic ponds considered in this study presented high periphytic biomass, but with low Zygnematophyceae representativeness. The periphyton attributes were not significantly different between macrophytes and rocks. The substrate type was not a determinant factor for Zygnematophyceae periphytic algae in the studied ponds.

“…In freshwater benthic habitats, data on small-scale algal differentiation are less numerous. Recent studies concentrated on regional or large-scale processes of individual catchment areas (CHARLES et al, 2006), water bodies (PALS et al, 2006) or running waters (e.g., PASSY, 2001;SOININEN, 2005). The spatial organization of benthic invertebrate communities in two oligotrophic lakes was characterized by STOFFELS et al (2005).…”

Samples of phytobenthos were collected during three different seasons in 2005 along a linear transect of a lowland peat bog at various spatial scales (10 cm, 1 m, 10 m) to investigate the seasonal dynamics, diversity, and factors influencing the spatial patterns of microalgal communities. Non-metric multidimensional scaling (NMDS), similarity percentage (SIMPER) analyses, ANOSIM, Mantel tests and diversity indices were used to analyze the data. Seasonal dynamics were exhibited by an increase in diversity, and a decrease in dominance from May to October, with significant differences in species composition. Mantel tests showed the significant influence of distance, microhabitat type, and conductivity on maintaining the similarity of species composition on scales of 1 m and 10 m. The small-scale processes (colonization and niche differentiation), microhabitat type, geographic distance and conductivity were found to be the main factors influencing the distribution of algal assemblages. We conclude that these factors are related to winter disturbance, and the consequent colonization and subsequent niche differentiation.
