MOLECULAR AND MORPHOLOGICAL CHARACTERIZATION OF TEN POLAR AND NEAR‐POLAR STRAINS WITHIN THE OSCILLATORIALES (CYANOBACTERIA) 1
An approximately 1400‐bp region of the 16S rRNA gene was sequenced for 10 polar or near‐polar strains putatively placed in the Oscillatorialean genera Oscillatoria, Phormidium, and Lyngbya obtained…

SYSTEMATICS OF THE BATRACHOSPERMALES (RHODOPHYTA)—A SYNTHESIS 1
TLDR
This taxonomic synthesis increases the level of monophyly within the Batrachospermales but minimizes taxonomic change where data are still inadequate, resulting in a few relatively conservative taxonomic changes.

PHYLOGENY OF THE BATRACHOSPERMALES (RHODOPHYTA) INFERRED FROM rbcL AND 18S RIBOSOMAL DNA GENE SEQUENCES
The sequence data from the large subunit of ribulose‐1,5‐bisphosphate carboxylase/oxygenase (rbcL) gene and 18S ribosomal DNA (small subunit) of taxa in the freshwater rhodophyte order…

TLDR
There was a predictable relationship between post-reclamation stream water quality and diatom assemblages, which may prove useful in assessment and management of reclamation efforts.

Biogeography and systematics of Bangia (Bangiales, Rhodophyta) based on the Rubisco spacer, rbcL gene and 18S rRNA gene sequences and morphometric analyses. 1. North America
TLDR
Marine and freshwater populations of the red alga Bangia were sampled throughout most of the known geographic range in North America, indicating that a single lineage may exist in freshwater systems.

Distribution and systematics of the freshwater red algal family Thoreaceae in North America
North American populations and type specimens of Thorea and Nemalionopsis were compared using multivariate morphometrics and image analysis. We continue to recognise the separation of the two genera…

TLDR
Considering the links between biofilm structure and function can provide a framework for developing management strategies to restore and conserve ecosystem processes, such as nutrient retention and spiraling, energy flow, food webs, and biodiversity.

Molecular and morphological evidence for Sheathia gen. nov. (Batrachospermales, Rhodophyta) and three new species
TLDR
It is found that heterocortication, the presence of both cylindrical and bulbous cells on the main axis, is an underlying synapomorphy of this clade Batrachospermum section Helminthoidea.
