Growth patterns of the Cambrian microbialite: Phototropism and speciation of Epiphyton
Sedimentary Geology, 2010Abstract Microbes started constructing shallow marine stromatolitic bioherms in the Archean, but they transferred their role as a major buildup maker to metazoans in Phanerozoic. Microbial buildups often recovered their predominance in the carbonate platform when reefal metazoan communities collapsed.

Heterotrophic bacteria in epiphyton of higher aquatic plants in the Ivankovo Reservoir
Inland Water Biology, 2017Concentrations of heterotrophic bacteria have been measured in the epiphyton of seven species of higher aquatic plants in the Ivankovo Reservoir. The abundance and biomass of the bacterioepiphyton range from 64.1 × 106 to 283.7 × 106 cells/сm2 and from 1.6 to 6.7 μg С/сm2. Maximum values are recorded in the epiphyton of emergent aquatic plants.

Spatial variability of epiphyton communities structure in a temperate estuarine lagoon
Estuarine, Coastal and Shelf Science, 2012The midsummer epiphyton community structure on common reed stems was investigated in different zones of the Curonian Lagoon (south-eastern Baltic). Epiphyton was characterized by dominance of diatoms and cyanobacteria. The shading effects of phytoplankton or reed belts density and phosphorus concentrations mainly contributed to differences in epiphyton

Algal dominance between phytoplankton and epiphyton plays an essential role in predicting shallow lake shifts between clear-water and turbid-water states. However, compared to resources competition, studies on algal life-form shifts between phytoplankton and epiphyton have traditionally received less interest, as few studies have focused on algal ...

Phosphatized Epiphyton from the terminal Neoproterozoic and its significance
Precambrian Research, 2019Abstract The fossil record of calcified cyanobacteria in the Precambrian is scarce, especially for fossils with dichotomous filaments. Epiphyton, which have complex branching structures like cyanobacteria and are usually regarded as calcimicrobe with uncertain affinity, and are widely considered to appear at the beginning of the Cambrian.

Seasonal succession of diatom epiphyton on dense mats of Lemna minor
Canadian Journal of Botany, 1985Annual sequences of biomass, species diversity, and community composition of epiphytic diatoms on a dense mat of Lemna minor L. growing in a freshwater marsh are described. In 2 successive years, maximum biomass occurred in early spring prior to occlusion of the water surface by the mat, while diversity reached relative maxima in the early summer ...

Epiphyton Pigment Indices in the River Section of the Kaniv Reservoir (Ukraine)
Hydrobiological JournalThe content of photosynthetic pigments (chlorophyll <i>a, b, c</i> and carotenoids) was studied in algal epiphyton of nine species of higher aquatic plants of various ecological groups occurring in the river section of the Kaniv Reservoir. It has been found that these indices varied over a wide range. Thus, in the fouling of emergent plants,

Comparative data from field observations in August 2005 and 2013 on phytoplankton and epiphyton productivity in the Ivankovo and Uglich reservoirs (Upper Volga) are presented. The average chlorophyll content (Chl a) varies from 7.6 ± 1.6 to 39.1 ± 0.7 μg/L in plankton and from 6.6 ± 2.8 to 28.4 ± 4.2 mg/m2 of the substrate in epiphyton; the daily ...

Epiphyton of a cascade plain reservoir under different hydrodynamic conditions
Ecohydrology and Hydrobiology, 2019Abstract The paper deals with the study of the influence of hydrodynamic factors (current, water level fluctuations, and wind driven wave) on the structure of epiphyton occurring on macrophytes of various ecological groups in the Kanev Reservoir (the Dnieper River, Ukraine).

The epiphyton on 22 macrophyte species was studied in the hypertrophic stratified Lake Verevi mainly in the midsummer of 2000 and 2001. Some material from 1998 and 1999 was used as well. Chlorophyll a (Chl a) level was high: 330–360 μg g dw−1 on emergent plants, and an average of 117–200 μg on floating-leaved plants and 820–920 μg g dw−1 on submerged ...
