Pyrosequencing-Based Assessment of Bacterial Community Structure Along Different Management Types in German Forest and Grassland Soils
TLDR
Soil bacterial community composition and diversity of the six analyzed management types showed significant differences between the land use types grassland and forest, and bacterial community structure was largely driven by tree species and soil pH.
Fatty acid profiles and their distribution patterns in microalgae: a comprehensive analysis of more than 2000 strains from the SAG culture collection
TLDR
FA distribution patterns are suitable chemotaxonomic markers to define taxa of higher rank in algae, however, due to their extensive variation at the species level it is difficult to make predictions about the FA profile in a novel isolate.
JENUFA GEN. NOV.: A NEW GENUS OF COCCOID GREEN ALGAE (CHLOROPHYCEAE, INCERTAE SEDIS) PREVIOUSLY RECORDED BY ENVIRONMENTAL SEQUENCING 1
TLDR
Two almost identical environmental 18S rDNA sequences from an endolithic microbial community occurring in dolomite rock in the central Alps turned out to be specifically related to, yet apparently distinct from, the sequence of J. minuta, indicating the existence of an undescribed Jenufa species occurring in the temperate zone.
Temperature-related phenotypic plasticity in the green microalga Micrasterias rotata
TLDR
Temperature-related morphological variation of Micrasterias rotata (Desmidiales) strain CAUP K604 was investigated using landmark-based geometric morphometrics and shape variation related to temperature was similar to the size-related change in shape.
Widespread green algae Chlorella and Stichococcus exhibit polar-temperate and tropical-temperate biogeography.
TLDR
A phylogenetic analysis of an expanded SSU and ITS2 rDNA sequence dataset representing Chlorella- and Stichococcus-like species from terrestrial habitats of polar, temperate and tropical regions aims to uncover biogeographical patterns at low taxonomic levels and finds that psychrotolerant strains of Ch Lorella and Sticococcus are closely related with strains originating from the temperate zone.
Green algae in soil: assessing their biodiversity and biogeography with molecular-phylogenetic methods based on cultures
TLDR
The phylogenetic diversity of green microlagae isolated from Central European soils and from periodically desiccating freshwater creek biofilms is uncovered and the existence of biogeography of airborne microalgae is suggested.
Interannual variation in land-use intensity enhances grassland multidiversity
TLDR
It is concluded that encouraging farmers to change the intensity of their land use over time could be an important strategy to maintain high biodiversity in grasslands, and a new measure of whole-ecosystem biodiversity, multidiversity is introduced, which integrates the species richness of 49 different organism groups ranging from bacteria to birds.
Biodiversity of soil cyanobacteria in the hyper‐arid Atacama Desert, Chile
TLDR
The cyanobacterial diversity of soils of the Atacama Desert (Chile) was investigated using 16S rRNA gene cloning/sequencing directly from soil samples and unialgal cultures, revealing a high diversity of phylotypes, among which are likely both new genera and new species awaiting characterization and description.
Diversity of Microscopic Green Algae (Chlorophyta) in Calcifying Biofilms of Two Karstic Streams in Germany
TLDR
The genus Gongrosira Kützing, often reported from freshwater tufa-stromatolites, was found to represent most likely a collective morphotype formed by several genera nested within the Ulvophyceae.
Chloromonas arctica sp. nov., a psychrotolerant alga from snow in the High Arctic (Chlamydomonadales, Chlorophyta).
TLDR
A morphological, ultrastructural and taxonomic description of a new Chloromonas-like alga isolated from snow in the High Arctic (Svalbard) revealing the psychrotolerant nature of the strain is focused on.
