“…In the present study, Pseudo-nitzschia species were observed to be more abundant in the lower and middle estuary in January and May, but they were also observed in June and August. This indicates that, although Pseudo-nitzschia species are found to be more abundant at low temperatures, they might adapt a wide temperature range and there are likely to be different species blooming in different seasons, as observed in the Gulf of Naples (Ruggiero et al, 2015). Pseudo-nitzschia species were also common in the Black Sea coast and numbers surpass 1.0×10…”

Distribution of potentially harmful microalgae and algal blooms were investigated at monthly and weekly time scales between October 2009 and September 2010 in the Golden Horn, a eutrophic estuary in the Sea of Marmara (Turkey). Several physical and chemical parameters were analysed together with phytoplankton composition and abundance. A total number of 23 potentially harmful and/or bloom-forming microalgae (14 dinoflagellates, 4 diatoms and 5 phytoflagellates) were identified throughout this study period, of which nine taxa have been confirmed to be toxic elsewhere in the world. Most harmful species and algal blooms were observed in late spring and summer particularly in the middle and upper estuaries, and nine taxa formed dense and successive algal blooms causing water discoloration. Nutrient concentrations increased significantly from the lower to the upper estuary. Additionally, high organic matter loads in the upper estuary could also have benefited by mixotrophic species. The increasing number of potentially harmful and bloom-forming species and algal blooms indicated that the GHE is a potential risk area for future HABs.

“…For example, targeted molecular analyses revealed that cryptic species in the genus Pseudonitzschia sampled from Puget Sound, Washington, varied in their relative abundances over space and time, and shifts in species composition were correlated with different environmental conditions (Hubbard et al 2014). Similarly, cryptic species of Pseudonitzschia in the Gulf of Naples showed distinct patterns of species occurrence over time (Ruggiero et al 2015). In the diatom family Leptocylindraceae, a targeted analysis of small subunit rDNA revealed unique temporal and geographical distributions of individual cryptic species sampled from the northeastern Atlantic and Mediterranean coasts (Nanjappa et al 2014).…”

“…The use of markers such as cox1 ( Evans et al, 2007) , rbcL ( Hamsher et al, 2011) and rDNA ( e. g. Moniz and Kaczmarska, 2009;Ruggiero et al, 2015;Zimmermann et al, 2014) has been proposed for barcoding purposes. Tests of these methods have yielded good results in differentiating closely-related species.…”

Diatoms are important contributors to the benthic microeukaryote flora. This manuscript lays the foundation for future metagenomic and environmental sequencing projects off coastal China by curating diatom DNA sequences from the Yantai region of the Bohai and Yellow Seas ( Northeast China) . These studies are based on cultures established from samples collected in different seasons from marine littoral and supralittoral zones in 2013 and 2014. Thirty-six diatom strains were cultured successfully and identification of these clones was determined by light and scanning electron microscopy( LM and SEM) and DNA sequencing of the nuclear-encoded small subunit ribosomal RNA ( SSU) and chloroplast-encoded rbcL and psbC genes. The strains primarily represent raphid pennate genera, such as Amphora, Amphora ( Oxyamphora) , Caloneis, Diploneis, Halamphora, Navicula, Nitzschia, Parlibellus, Pleurosigma, Surirella and Tryblionella. When the DNA markers from these strains were analysed in a multi-gene phylogeny, we found that some clones-particularly within the genera Amphora, Navicula and Nitzschia-show greater than expected genetic diversity despite their very similar morphology and morphometrics. We also compared the molecular and morphological identities of several seemingly ubiquitous marine littoral taxa in the genera Amphora and Nitzschia from the Indian Ocean and Atlantic Ocean, the Red Sea and Adriatic Sea to their Yellow Sea counterparts.
