Acclimation to various temperature and pCO2 levels does not impact the competitive ability of two strains of Skeletonema marinoi in natural communities
Briddon, Charlotte L.; Nicoară, Maria; Hegedüs, Adriana; Niculea, Adina; Bellerby, Richard; Eikrem, Wenche; Gomez Crespo, Bibiana; Dupont, Sam; Drugă, Bogdan (Peer reviewed; Journal article, 2023)Understanding the long-term response of key marine phytoplankton species to ongoing global changes is pivotal in determining how oceanic community composition will respond over the coming decades. To better understand the ... -
Changes in phytoplankton community structure over a century in relation to environmental factors
Lundsør, Elisabeth; Eikrem, Wenche; Stige, Leif Christian; Engesmo, Anette; Gran-Stadniczeñko, Sandra; Edvardsen, Bente (Peer reviewed; Journal article, 2022)Changes in phytoplankton abundance and biomass during the period 1933–2020 were examined by statistical modeling using data from the Inner Oslofjorden phytoplankton database. The phytoplankton abundances increased with ... -
Chloropicophyceae, a new class of picophytoplanktonic prasinophytes
Lopes Dos Santos, Adriana; Pollina, Thibaut; Gourvil, Priscillia; Corre, Erwan; Marie, Dominique; Garrido, Jose Luis; Rodriguez, Francisco; Noel, Mary-Helene; Vaulot, Daniel; Eikrem, Wenche (Journal article; Peer reviewed, 2017)Prasinophytes are a paraphyletic group of nine lineages of green microalgae that are currently classified either at the class or order level or as clades without formal taxonomic description. Prasinophyte clade VII comprises ... -
Development of a qPCR assay to detect and quantify ichthyotoxic flagellates along the Norwegian coast, and the first Norwegian record of Fibrocapsa japonica (Raphidophyceae)
Engesmo, Anette; Strand, David; Gran-Stadniczeñko, Sandra; Edvardsen, Bente; Medlin, Linda K.; Eikrem, Wenche (Journal article; Peer reviewed, 2018)Blooms of ichthyotoxic microalgae pose a great challenge to the aquaculture industry world-wide, and there is a need for fast and specific methods for their detection and quantification in monitoring programs. In this ... -
Harmful algal blooms and their effects in coastal seas of Northern Europe
Karlson, Bengt; Andersen, Per; Arneborg, Lars; Cembella, Allan; Eikrem, Wenche; John, Uwe; West, Jennifer Joy; Klemm, Kerstin; Kobos, Justyna; Lehtinen, Sirpa; Lundholm, Nina; Mazur-Marzec, Hanna; Naustvoll, Lars Johan; Poelman, Marnix; Provoost, Pieter; De Rijcke, Maarten; Suikkanan, Sanna (Peer reviewed; Journal article, 2021)Harmful algal blooms (HAB) are recurrent phenomena in northern Europe along the coasts of the Baltic Sea, Kattegat-Skagerrak, eastern North Sea, Norwegian Sea and the Barents Sea. These HABs have caused occasional massive ... -
Mantoniella beaufortii and Mantoniella baffinensis sp. nov. (Mamiellales, Mamiellophyceae), two new green algal species from the high arctic
Yau, Sheree; Lopes dos Santos, Adriana; Eikrem, Wenche; Gérikas Ribeiro, Catherine; Gourvil, Priscillia; Balzano, Sergio; Escande, Marie-Line; Moreau, Hervé; Vaulot, Daniel (Peer reviewed; Journal article, 2019)Members of the class Mamiellophyceae comprise species that can dominate picophytoplankton diversity in polar waters. Yet, polar species are often morphologically indistinguishable from temperate species, although clearly ... -
Marine phytoplankton community data and corresponding environmental properties from eastern Norway, 1896–2020
Lundsør, Elisabeth; Lømsland, Evy Rigmor; Johnsen, Torbjørn Martin; Engesmo, Anette; King, Andrew Luke; Staalstrøm, Andre; Norli, Marit; Magnusson, Jan; Sørensen, Kai; Edvardsen, Bente; Eikrem, Wenche (Peer reviewed; Journal article, 2022)Time series are essential for studying the long-term effects of human impact and climatic changes on the natural environment. Although data exist, no long-term phytoplankton dataset for the Norwegian coastal area has been ... -
Olisthodiscus represents a new class of Ochrophyta
Barcytė, Dovilė; Eikrem, Wenche; Engesmo, Anette; Seoane, Sergio; Wohlmann, Jens; Horak, Ales; Yurchenko, Tatiana; Elias, Marek (Peer reviewed; Journal article, 2021)The phylogenetic diversity of Ochrophyta, a diverse and ecologically important radiation of algae, is still incompletely understood even at the level of the principal lineages. One taxon that has eluded simple classification ... -
Protist Diversity and Seasonal Dynamics in Skagerrak Plankton Communities as Revealed by Metabarcoding and Microscopy
Gran-Stadniczenko, Sandra; Egge, Elianne; Hostyeva, Vladyslava; Logares, Ramiro; Eikrem, Wenche; Edvardsen, Bente (Journal article; Peer reviewed, 2019)Protist community composition and seasonal dynamics are of major importance for the production of higher trophic levels, such as zooplankton and fish. Our aim was to reveal how the protist community in the Skagerrak changes ... -
