Seasonal shifts in the importance of bottom–up and top–down factors on stream periphyton community structure

Oikos, 2018
We examined the importance of temporal variability in top–down and bottom–up effects on the accumulation of stream periphyton, which are complex associations of autotrophic and heterotrophic microorganisms.

In situ bioremediation of surface waters by periphytons

Bioresource Technology, 2014
Environmentally benign and sustainable biomeasures have become attractive options for the in situ remediation of polluted surface waters. In this paper, we review the current state of reported experiments utilizing naturally occurring periphyton. These are microbial communities consisting of heterotrophic and photoautotrophic microorganisms that are ...

Periphyton removal by freshwater micrograzers

1994
In various experiments, the freshwater snail species Lymnaea peregra (Mull.), Physa fontinalis (L.), Valvata piscinalis (Mull.) and Bithynia tentaculata (L.) significantly removed periphyton from glass slides, while the two tested crustacean species, Asellus aquaticus (L.) and Gammarus pulex (L.), did not.

Grazer control of nutrient availability in the periphyton

Oecologia, 1991
Benthic algal assemblages are regulated by both abiotic (e.g., nutrient) and biotic (e.g., grazing) constraint. The objective of this study was to determine how changes in these two factors affected the structure of an algal assemblage in an ephemeral stream.

Combinations of Ulva and periphyton as biofilters for both ammonia and nitrate in mariculture fishpond effluents

Algal Research, 2018
Periphyton-based biofilters for aquaculture effluent possess multiple advantages, in water oxygenation, CO2 reduction and production of useful biomass. The performance of a marine periphyton biofilter, in terms of uptake rate and efficiency in removing ...

Paddy periphyton: Potential roles for salt and nutrient management in degraded mudflats from coastal reclamation

Land Degradation and Development, 2018
Periphyton exists ubiquitously in paddy ecosystems of coastal mudflat area, playing significant roles in salt and nutrient cycling between the water and soil interface.

Primary Productivity of Periphyton

Nature, 1963
THE difficult problem of assaying biomass and rates of colonization by periphyton in fresh and saline waters has been recognized for many years. The most common method used in these investigations has involved the measurement of rates of colonization by periphyton on artificial substrata.

Phytosociological associations of algal periphyton

1983
In the search for a method to distinguish ecological units of periphytic algal communities, the phytosociological method was applied. On the basis of numerous samples collected from 49 lakes, it was found that there occur two associations in the lakes of Northern Poland: Oedogonio-Epithemietum litoralae in eutrophic lakes, and Hapalosiphono ...
