Photophysiological response of diatoms in surface sediments to light exposure: A laboratory experiment on a diatom community in sediments from the Chukchi Sea

Autor: Yuri Fukai, Kohei Matsuno, Amane Fujiwara, Koji Suzuki

Publikováno v: Frontiers in Marine Science, Vol 9 (2022)

Diatoms form dense blooms in the Pacific Arctic region from spring to summer, supporting the unique benthic-pelagic coupling ecosystems. Although the Arctic has a severe light-limited season from autumn to winter, diatoms can proliferate in spring wh

Among the organisms that spread into and flourish in Arctic waters with rising temperatures and sea ice loss are toxic algae, a group of harmful algal bloom species that produce potent biotoxins. Alexandrium catenella, a cyst-forming dinoflagellate t

Significance The neurotoxin-producing dinoflagellate Alexandrium catenella is shown to be distributed widely and at high concentrations in bottom sediments and surface waters of the Alaskan Arctic. Future blooms are likely to be large and frequent gi

Impact of sea-ice dynamics on the spatial distribution of diatom resting stages in sediments of the Pacific Arctic region

Autor: Yuri Fukai, Mindy L. Richlen, Koji Suzuki, Kohei Matsuno, Donald M. Anderson, Evangeline Fachon, Amane Fujiwara

The Pacific Arctic region is characterized by seasonal sea-ice, the spatial extent and duration of which varies considerably. In this region, diatoms are the dominant phytoplankton group during spr...

The community composition of diatom resting stages in sediments of the northern Bering Sea in 2017 and 2018: the relationship to the interannual changes in the extent of the sea ice

Autor: Yuri Fukai, Amane Fujiwara, Atsushi Yamaguchi, Kohei Matsuno

Publikováno v: Polar Biology. 42:1915-1922

In the Bering Sea shelf, annual changes in the sea ice extent are large. In this study, we compare the viable diatom resting stages in sediments during the summer of 2017 when the sea ice retreat was late and 2018 when the sea ice retreat was early.

Between-year comparison of interactions between environmental parameters and various plankton stocks in the northern Bering Sea during the summers of 2017 and 2018

Publikováno v: Polar Science. :100555

In the northern Bering Sea, ice coverage and retreat timing were low and early, respectively, in the 2017–2018 winter. To evaluate the effect of these anomalous ice conditions, we quantified various environmental parameters (temperature, salinity,

Spatial changes in the summer diatom community of the northern Bering Sea in 2017 and 2018

Autor: Yoshiyuki Abe, Atsushi Yamaguchi, Kohei Matsuno, Yuri Fukai

Publikováno v: Deep Sea Research Part II: Topical Studies in Oceanography. :104903

In recent years, the northern Bering Sea has experienced changes in the timing of sea-ice retreat and in hydrographic conditions during the summer. The influence of these environmental changes on the diatom community has not been examined. In this st
