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 …

Marine ecosystems are undergoing substantial changes due to human-induced pressures.
Analysis of long-term data series is a valuable tool for understanding naturally and …

A bloom of the fish-killing haptophyte Chrysochromulina leadbeateri in northern Norway
during May and June 2019 was the most harmful algal event ever recorded in the region …

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 …

Next generation sequencing of ribosomal DNA is increasingly used to assess the diversity
and structure of microbial communities. Here we test the ability of 454 pyrosequencing to …

Microalgae in the division Haptophyta play key roles in the marine ecosystem and in global
biogeochemical processes. Despite their ecological importance, knowledge on seasonal …

The species composition of plankton, insect and annual plant communities may vary
markedly from year to year. Such interannual variability is usually thought to be driven by …

Microalgae in the division Haptophyta may be difficult to identify to species by microscopy
because they are small and fragile. Here, we used high‐throughput sequencing to explore …

Haptophyta encompasses more than 300 species of mostly marine pico‐and
nanoplanktonic flagellates. Our aims were to investigate the Oslofjorden haptophyte …

Abstract Changes in phytoplankton abundance and biomass during the period 1933–2020
were examined by statistical modeling using data from the Inner Oslofjorden phytoplankton …
