“…The fine structure of valves was examined with a transmission electron microscope JEM-100 JEOL S (TEM) and a scanning electron microscope Carl Zeiss Leo 430 (SEM). Material for TEM was prepared according to the standard procedure (Hasle & Fryxell 1970, Shevchenko & Ponomareva 2015. Algae were considered to be blooming at concentrations exceeding 10 6 cells/L (Colijn 1992).…”

The article presents an annotated list of microalgal species in the coastal waters off Russky Island (Sea of Japan) based on original and literature data. A total of 254 taxa of microalgae from ten classes are identified. Descriptions and photographic illustrations are provided for the diatom species of the genus Skeletonema and prymnesiophyta Pseudohaptolina sorokinii, which are rare in the seas of Russia. Information on 20 species of potentially toxic microalgae observed in the study area is also provided.

“…More than 150 years have passed since the original description of the genus Skeletonema [10], and until the early 2000s it was usually referred to as S. costatum due to the difficulty of light microscope identification [11]. In the early 2000s a more detailed morphological investigations together with new molecular insights revealed a more complex taxonomic and genetic diversity within the genus Skeletonema [12], and to this day there are more than 20 different species described, which formerly were recognized as only one species [13].…”

The Ecology of One Cosmopolitan, One Newly Introduced and One Occasionally Advected Species from the Genus Skeletonema in a Highly Structured Ecosystem, the Northern Adriatic

et al. 2017

The diatom genus Skeletonema is globally distributed and often an important constituent of the phytoplankton community. In the marine phytoplankton of the northern Adriatic Sea, we found three species of the genus Skeletonema: Skeletonema menzelii, Skeletonema marinoi and Skeletonema grevillei. Making use of the steep ecological gradients that characterise the northern Adriatic, along which we could observe those species, we report here on the ecological circumstances under which those species thrive and how their respective populations are globally connected. This is the first detailed ecological study for the species S. grevillei. This study is also the first report for S. grevillei for the Adriatic Sea and Mediterranean together with additional electron microscopic details on fresh in situ samples for this species. S. marinoi appears to clearly prefer strong freshwater influence and high nutrient concentrations delivered by low salinity waters. It can outcompete other diatom species and dominate microphytoplankton blooms. S. grevillei on the other hand appears to thrive in high nutrient concentrations triggered by water column mixing. It also appears to prefer higher salinity waters and coastal embayments. Genetic analysis of S. grevillei demonstrated a peculiar dissimilarity with isolates from coastal waters off Yemen, India, Oman and China. However, a closely related sequence was isolated from coastal waters off Japan. These results indicate that S. grevillei is an introduced species, possibly transported by ballast waters. S. menzelii is a sporadic visitor in the northern Adriatic, advected from rather oligotrophic middle Adriatic waters and never dominates the phytoplankton community in the northern Adriatic.

Skeletonema species (Bacillariophyta) from the northwestern Sea of Japan: morphology, ecology, seasonal and long-term dynamics

et al. 2022

Skeletonema species are among the most important components of phytoplankton communities in the temperate and tropical Pacific Ocean. Data on Skeletonema species diversity and abundance in the northeastern Pacific are fragmentary. The long-term observations (1996–2019) of the phytoplankton from the coastal waters of the northwestern Sea of Japan resulted in five Skeletonema species being recorded: Skeletonema costatum, S. dohrnii, S. japonicum, S. marinoi and S. menzelii. For each of the species, a morphological description is provided based on electron microscopy. Ecological factors influencing the distribution of the species and their occurrence under certain environmental parameters are discussed. One of the species, S. menzelii, is a new record for Russia. Skeletonema costatum was confirmed to occur in the study area. Seasonal and interannual changes in the abundance of Skeletonema species were studied. The concentrations of the species varied from 20 cells l−1 to 12,700,000 cells l−1. From 1996 to 2018 there was a downward trend in the numbers of Skeletonema. Skeletonema japonicum was noted for the first time to bloom. Skeletonema dohrnii formed summer blooms; S. japonicum bloomed in the autumn. No Skeletonema blooms were detected in the winter months.
