  • Salt tolerance and polyphyly in the cyanobacterium Chroococcidiopsis (Pleurocapsales)

    Salt tolerance and polyphyly in the cyanobacterium Chroococcidiopsis (Pleurocapsales)

    Micrographs of five strains of Chroococcidiopsis from this study mapped to the 16S rRNA cladogram with polytomies collapsed (see Fig. S1). Images demonstrate the diversity of morphology within the genus.

  • Molecular and morphological evidence for Sheathia gen. nov. (Batrachospermales, Rhodophyta) and three new species

    Molecular and morphological evidence for Sheathia gen. nov. (Batrachospermales, Rhodophyta) and three new species

    Morphological characters of Sheathia exigua sp. nov. (a–f) and S. americana sp. nov. (g–l).

  • Effects of brefeldin A on the endomembrane system and germ tube formation of the tetraspore of Gelidium floridanum (Rhodophyta, Florideophyceae)

    Effects of brefeldin A on the endomembrane system and germ tube formation of the tetraspore of Gelidium floridanum (Rhodophyta, Florideophyceae)

    Gelidium floridanum tetraspores during the process of forming the germ tube. (a) Tetraspore after release. (b, c) Early germination with increase of vacuoles on one side and the formation of the germ tube on the other side. (d–f) Displacement of organelles toward the region of tube formation (arrows).

  • Menadione-induced caspase-dependent programmed cell death in the green chlorophyte Chlamydomonas reinhardtii

    Menadione-induced caspase-dependent programmed cell death in the green chlorophyte Chlamydomonas reinhardtii

    Terminal deoxynucle-otidyl transferase-mediated dUTP nick end-labeling (TUNEL) staining of Chlamydomonas reinhardtii cells (Control and Menadione-treated cells). Arrows indicate TUNEL-positive nuclei; scale bar = 10 μm.

  • Taxonomic identification of algae (morphological and molecular): species concepts, methodologies, and their implications for ecological bioassessment

    Taxonomic identification of algae (morphological and molecular): species concepts, methodologies, and their implications for ecological bioassessment

    A visual representation of the use of algae in bioassessment from planning to inferences about ecosystem integrity represented in a random sample and measured with algal species composition. Algal samples are processed without preservation for molecular analyses (in blue), a subsample of the same community can be preserved and analyzed for all algae present (whole algal groups analyses in green), and a third subsample can be digested from organic material and analyzed for diatoms (diatom analyses in brown). Gray compartments represent stages related to all three methods.
