Taxonomy and nomenclature of the Conjugatophyceae (= Zygnematophyceae) [PDF]
Algae, 2013 The conjugating algae, an almost exclusively freshwater and extraordinarily diverse group of streptophyte green algae, are referred to a class generally known as the Conjugatophyceae in Central Europe and the Zygnematophyceae elsewhere in the world. Conjugatophyceae is widely considered to be a descriptive name and Zygnematophyceae ('Zygnemophyceae' a ...

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 ...

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.

New records of the genus Spirogyra (Zygnemataceae, Conjugatophyceae) in Korea
Journal of Ecology and Environment, 2015 Spirogyra is a zygnematalean green algal genus that is ubiquitous in a broad range of freshwater habitats throughout the world. Samples collected throughout Korea from October 2004 to July 2015 were examined using light microscopy. Morphological characteristics (e.g., size of vegetative cells, number of chloroplasts in each cell, type of end walls of ...
