PFOS was tested for acute toxicity on the cyanobacterium Microcystis aeruginosa in terms of growth, photosynthetic pigment content, antioxidant response and microcystin production. When exposed to PFOS, the cyanobacterium was sensitive to it, showing significant inhibition of growth and reduction of pigment content. At the same time, exposure to PFOS resulted in a two-fold increase of the content of total carbohydrates and soluble proteins in the cells of M. aeruginosa. There was a significant increase in MDA and H2O2 levels in cells exposed to PFOS, but not in a concentration-dependent manner. Microcystin content tended to increase in PFOS-exposed cyanobacterial cells, although this change was not statistically significant (p > 0.05). These findings suggest that when surfactants like PFOS are used in large quantities or concentrations, they could adversely affect Microcystis populations in the aquatic environment.","PeriodicalId":20140,"journal":{"name":"Phycologia","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2023-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47594138","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cells of C. sabulosa are oval, small (14.5–28.3 µm long and 11.1–18.0 µm wide), dorsoventrally compressed, and show a conspicuous apical hook projection pointing to the right. The epitheca is smaller than the hypotheca and the cingulum is ascending, about 3× its width. The thecal plate pattern is unusual and interpreted as APC, 4ʹ, 3a, 7ʹʹ, 5c, 4s, 6ʹʹʹ, 2ʹʹʹʹ. The APC comprises a narrow Po plate with a slit opening, located on the right-dorsal side, and it is covered by a projection of the first apical plate. Morphologically, the plate pattern has some affinities with Amphidiniella sedentaria, a sand-dwelling dinoflagellate species of roughly the same size and gross outline. However, the two taxa differ from each other in shape, size of epitheca and organization of the APC. They possess the same number of apical, precingular, postcingular and antapical plates but their relative sizes, shapes and especially the arrangement differs. Molecular phylogeny inferred from concatenated ribosomal genes reveals that C. sabulosa forms a well supported clade in the core dinoflagellates, but it is not related to any other existing taxa and diverges widely from A. sedentaria. From the present study, this new taxon appears very atypical among dinoflagellates, and further studies will be necessary to resolve its evolutionary position.","PeriodicalId":20140,"journal":{"name":"Phycologia","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2023-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48116655","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Names were applied by comparing these DNA sequences with sequences obtained from type specimens, including a 263 bp rbcL sequence from an isotype of C. chilensis collected by Darwin (C. Darwin 2151) from Valparaiso, Chile. DNA sequences from the C. chilensis isotype matched unnamed coralline DNA sequences from British Columbia, Canada, and previously published DNA sequences from the northeast and southeast Pacific. The clade containing the isotype of C. chilensis was distinct from C. officinalis specimens in phylogenetic analyses. Although morphologically variable, fronds of C. chilensis from British Columbia populations matched Kützing’s original description of C. officinalis var. chilensis.

Seaweeds and seagrasses, traditionally consumed as vegetables in coastal areas worldwide, are generally known as a rich source of macro- and microminerals in concentrations much higher than in terrestrial plants. Despite their significant nutritional potential, the mineral composition of most of the seaweeds and seagrasses remains unexplored. In the present study, the concentrations of 23 minerals in nine seaweeds and seagrasses from the Philippines were determined using inductively coupled plasma optical emission spectroscopy. The results showed that some of the species are excellent sources of various essential minerals. Actinotrichia fragilis and Mastophora rosea were the highest in calcium content (21,511 and 14,100 mg/100 g DM, respectively), and, together with Anadyomene plicata, they were richest in copper (2.49–3.77 mg/100 g DM), iron (292–480 mg/100 g DM), manganese (22.3–27.2 mg/100 g DM), and nickel (1.49–2.93 mg/100 g DM). Moreover, M. rosea had the highest content of magnesium (2,093 mg/100 g DM). Other species, such as Enhalus acoroides (phosphorus in flowers and seeds, 277 and 282 mg/100 g DM, respectively), Halophila ovalis (silicon, 13.8 mg/100 g DM), Halymenia dilatata (zinc, 5.51 mg/100 g DM), Halymenia maculata (sulphur, 8,268 mg/100 g DM) and Portieria hornemannii (potassium, 8,985 mg/100 g DM; vanadium, 2.90 mg/100 g DM) can be highlighted as good sources of minerals.

An initial contribution to the taxonomy of Plocamium in South Africa was therefore carried out using combined morphological and molecular approaches and existing literature. Plocamium robertiae is reinstated as a distinct species based on molecular and morphological evidence, while Plocamium raphelisianum, a species from Spain, is placed in synonymy with P. suhrii. Along the South African coast, individuals of P. suhrii were genetically divergent in different bioregions and will require further investigation. Contrary to previous reports, we confirm the absence in South Africa of two Australasian species, P. microcladioides and P. mertensii, which were previosuly misidentified. The latter species likely represents a new, undescribed species in South Africa. Two additional species were also identified based on DNA but require further morphological assessment. We now recognize P. robertiae, along with eight other named species, plus five additional taxa, with varying levels of taxonomic confidence, and exclude P. microcladioides and P. mertensii from the South African flora. This study doubles the number of species recognized since the last biodiversity assessment of Plocamium and expands the distributional range of P. suhrii.

However, very few of the diatoms permit indefinite survival of the dinoflagellate and rbcL sequences show that D. capensis isolated from nature contains one of two closely related Nitzschia species as its kleptoplastids. In culture, without a supply of these ‘essential’ Nitzschia cells to replenish the intracellular store of diatom plastids and other organelles, D. capensis eventually loses all its kleptoplastids and dies. Inside Durinskia, diatoms do not possess frustules and so cannot be compared morphologically with free-living forms. Recently, one of the essential Nitzschia species was isolated from the type locality of D. capensis and grown in culture, allowing comparison with similar Nitzschia species, particularly N. agnita and N. kuetzingioides, examined from type material. We conclude that the ‘essential diatom’ of D. capensis differs morphologically from these and other Nitzschia species and it is therefore described as N. captiva sp. nov. Nitzschia agnita and N. kuetzingioides, on the other hand, are conspecific and N. agnita has priority. Nitzschia captiva and N. agnita are extremely similar in valve shape, dimensions, pattern and ultrastructure, but can be separated by their girdle structure.
