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

Acta Limnologica Brasiliensia, 2018
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

Diversified calcimicrobes in dendrolites of the Zhangxia Formation, Miaolingian Series (Middle Cambrian) of the North China craton

Journal of Palaeogeography, 2021
As a type of non-laminated microbial carbonates, dendrolites are dominated by isolated dendritic clusters of calcimicrobes and are distinct from stromatolites and thrombolites.

Algae in sphagnum epiphyton from the mires of the Subpolar Urals

Botanica Lithuanica, 2017
AbstractSpecies diversity of algal communities of sphagnum epiphyton was studied in six mountain and plain mires of the Subpolar Urals (Russia). A total of 154 species and intraspecific taxa from six divisions were identified. The highest species richness was recorded for Bacillariophyta (96 taxa) and Charophyta (33) divisions.

Planktonic algae and epiphyton of the littoral in lake Peipsi, Estonia

Limnologica, 2004
AbstractThe littoral plankton of Lake Peipsi (3555 km2, mean depth 7.1 m) was studied in summer 1980 and 2000–2002, and the epiphyton was studied on two dominating macrophytes, Phragmites australis (Cav.) Trin. ex Steud. and Potamogeton perfoliatus L., in 2000.

Response of primary producers to water level fluctuations of Lake Peipsi; pp. 231–245 [PDF]

Proceedings of the Estonian Academy of Sciences, 2018
The amplitude of natural fluctuation between annual averages of the water level (WL) of Lake Peipsi (3555 km2) is 1.5 m. A study aimed to examine the impact of WL fluctuations on phytoplankton, macrophytes, and their epiphyton was performed annually at

Quantification of environment-driven changes in epiphytic macroinvertebrate communities associated to Phragmites australis

Journal of Limnology, 2009
The epiphytic macroinvertebrate communities associated with the Common Reed, Phragmites australis (Cav.) Trin. ex Steudel, were examined seasonally from summer 2004 to spring 2005 in eleven coastal lagoons of the Llobregat Delta (NE Spain) following the ...
