Limnology and Oceanography: Methods, Volume 18, Issue 1, Page 1-7, January 2020., 2020 Abstract Periphytic biofilms are the major resource for many herbivorous invertebrates in both marine and freshwater benthos. They are of crucial importance for benthic food webs, substrate stability, and biogeochemical processes in littoral zones.

A single Thaumarchaeon drives nitrification in deep oligotrophic Lake Constance
Environmental Microbiology, Volume 22, Issue 1, Page 212-228, January 2020., 2020 Summary Ammonia released during organic matter mineralization is converted during nitrification to nitrate. We followed spatiotemporal dynamics of the nitrifying microbial community in deep oligotrophic Lake Constance. Depth‐dependent decrease of total ammonium (0.01–0.84 μM) indicated the hypolimnion as the major place of nitrification with 15N ...

On changes in the nomenclature of some taxa of Zygnemaceae
Acta Societatis Botanicorum Poloniae, 2014 The names of three species have been changed in the Zygnemaceae family because of their incompatibility with the principles of classification of the International Code of Botanical Nomenclature. The names and ranks of 18 taxa were also changed since they

Ecosystems of artificial saline lakes. A case of Lake Magic in Wadi El-Rayan depression (Egypt)
Knowledge and Management of Aquatic Ecosystems, 2020 The Wadi El-Rayan is a depression in the Fayoum oasis collecting agricultural drainage water from the Fayoum. Since 1973, this drainage water formed two man-made lakes. Twenty years ago, a third lake, called Lake Magic was formed. Since this newly formed

Inferring phytoplankton community composition with a fatty acid mixing model
Ecosphere, Volume 6, Issue 1, Page 1-18, January 2015., 2015 The taxon specificity of fatty acid composition in algal classes suggests that fatty acids could be used as chemotaxonomic markers for phytoplankton composition. The applicability of phospholipid‐derived fatty acids as chemotaxonomic markers for phytoplankton composition was evaluated by using a Bayesian fatty acid‐based mixing model.
