title: An insight into the cryptic diversity of Fragilariaceae (Bacillariophyta), with the description of a new Antarctic species, <i>Gedaniella antarctica</i> sp. nov.

description: Fragilariaceae is a paraphyletic family of araphid diatoms commonly used as bio-indicators, in environmental assessments and in paleoenvironmental reconstructions, and with various potential industrial applications. Recent molecular taxonomic research has highlighted significant limitations in traditional morphology-based investigations of these diatom species. Most descriptions of species and genera of the Fragilariaceae present broad morphological character definitions and many diagnostic characters are indistinguishable by light microscopy. In this sense, taxon misidentification is common and could have serious implications for environmental surveys and laboratory experiments. To better understand the diversity of the Fragilariaceae, we (1) performed phylogenetic analyses of the small subunit ribosomal RNA (18S rRNA), <i>rbc</i>L and <i>psb</i>C gene sequences, (2) inferred a cladogram from key morphological features used in the traditional identification of Fragilariaceae, (3) tested if the topologies of the tree recovered from the molecular phylogeny, of the tree based on morphology and of the trees constraining to monophyly the genera <i>Sarcophagodes, Pseudostaurosira</i> and <i>Nanofrustulum</i> (together and separately) were significantly different and (4) mapped morphological character states on the ML tree and inferred their evolution based on maximum parsimony. Our results supported the monophyly of a group of Fragilariaceae within small araphid diatoms including the genera <i>Cratericulifera, Plagiostriata, Castoridens, Opephora, Staurosira, Staurosirella, Punctastriata, Psammotaenia,</i> <i>Hendeyella, Stauroforma, Pseudostaurosira sensu Li</i>, <i>Nanofrustulum</i> sensu Li, <i>Serratifera</i> sensu Li and <i>Gedaniella</i> sensu Li. Molecular phylogeny and topology tests suggested that the latest circumscriptions of the genera <i>Sarcophagodes, Pseudostaurosira</i> and <i>Nanofrustulum</i> sensu Morales were not monophyletic. Analyses of the Antarctic strain IMA070A collected during the XXXIV Italian Antarctic Expedition using fine structural features of the frustule and molecular data revealed that this diatom belongs to a distinct lineage within <i>Gedaniella</i>, which we describe here as <i>Gedaniella antarctica</i> sp. nov.

title: Freshwater ‘microcroissants’ shed light on a novel higher-level clade within the Trebouxiophyceae and reveal the genus <i>Chlorolobion</i> to be a trebouxiophyte

description: The Trebouxiophyceae is a widespread and species-rich green algal class encompassing mostly coccoid algae with a simple spherical, ovoid or ellipsoidal outline. However, some poorly sampled lineages have evolved more elaborate shapes or even complex thalli, adding to the morphological diversity of the class. By investigating new and previously established strains, this study expands the range of morphologies exhibited by the class members by uncovering a clade of croissant-like trebouxiophytes. Phylogenetic analyses inferred from nuclear 18S rDNA and chloroplast <i>rbc</i>L sequences confirmed the monophyly of the ‘microcroissant’ clade, which we propose to be classified as a new family, Ragelichloridaceae. This family includes two novel genera, <i>Ragelichloris</i> and <i>Navichloris</i>, and the previously described <i>Thorsmoerkia</i>. The position of Ragelichloridaceae within Trebouxiophyceae stayed unresolved but chloroplast phylogenomics showed that the family belongs to the broader incertae sedis group that also includes <i>Xylochloris</i> and <i>Leptosira</i>. In addition, our study showed that the similar morphotype-bearing genus <i>Chlorolobion</i>, previously classified within Chlorophyceae, is a genuine trebouxiophyte, potentially related to Ragelichloridaceae. A new family-level clade uncovered within the Trebouxiophyceae.Two new genera, <i>Ragelichloris</i> and <i>Navichloris</i>, are described.The genus <i>Chlorolobion</i> is shown to be a trebouxiophyte.

title: <i>Plocamiomonas psychrophila</i> gen. et sp. nov. (Pelagophyceae, Heterokontophyta), an Arctic marine nanoflagellate characterized by microscopy, pigments and molecular phylogeny

description: During a field campaign in Baffin Bay (June, 1998), a sample dominated by small yellow brown biflagellates was collected from a small pocket of liquid water on the sea ice and established into a unialgal culture. Later it was given strain number CCMP2097 and deposited at the NCMA collection. Growth experiments over a range of temperatures and salinities indicated adaptation to variable Arctic conditions. This strain was studied here using light and transmission electron microscopy, HPLC for characterization of photosynthetic pigments and the relationship to related taxa was elucidated from molecular phylogeny. This integrative approach resulted in suggesting <i>Plocamiomonas psychrophila</i> gen. et sp. nov. the first systematically named Arctic species of the Pelagophyceae. <i>Plocamiomonas</i> had two unequally long flagella and the spherical cells measured 7.5 µm in diameter. Novel morphological characters included (1) a swelling on the mature flagellum, (2) a bi-layered theca, thin elongated arm-like structures emanating from the cell surface and (3) a thin filament above the flagellar transition region. This set of morphological characters represented a novel combination for the Pelagophyceae and together with evidence from the phylogenetic position of <i>Plocamiomonas</i> and eight uncultured cold-water pelagophytes supported the proposal of a new order Plocamiomonadales and a new family Plocamiomonadaceae.

title: The pH tolerance range of the airborne species <i>Tetracystis vinatzeri</i> (Chlorophyceae, Chlamydomonadales)

description: To decipher the dispersal range of the cosmopolitan green microalga <i>Tetracystis vinatzeri</i>, two airborne-collected strains were barcoded using the 18S ribosomal DNA gene (18S) and the mitochondrial cytochrome c oxidase I subunit (COI), and their survival capacities were investigated across a stepwise acidic to alkaline pH gradient. Genetic fingerprinting confirmed the identity of the strains as representing the same biological species. Investigations of the tolerance of <i>T. vinatzeri</i> to pH levels refined the delimitation of its ecological niche. <i>T. vinatzeri</i> showed optimal growth in freshwater habitats at pH 4.3–9.6 and strains could cope with exposure to slightly more acidic (down to 3.8) and alkaline (up to 10.4) conditions. However, organismal survival was drastically affected by exposure to pH &lt; 3 and &gt; 11. Morphological observations showed that <i>T. vinatzeri</i> could better cope with exposure to acidic pH, exhibiting less cell membrane damage. Genetic analysis showed that the two airborne strains shared the same haplotype, suggesting that they either originated from the same air mass or that the haplotype has a widespread distribution. Further phylogeographic and physiological investigations are required to define the spreading dynamic of <i>T. vinatzeri</i>. <i>Tetracystis vinatzeri</i> can grow at pH from 3.8–10.4.Strains from different habitats showed sexual compatibility.Low genetic diversity and cosmopolitan distribution suggest widespread dispersal. <i>Tetracystis vinatzeri</i> can grow at pH from 3.8–10.4.
