In this study, we measured depth-dependent benthic microalgal primary production in a
Bothnian Bay estuary to estimate the benthic contribution to total primary production. In …

Microbial plankton form the productive base of both marine and freshwater ecosystems and
are key drivers of global biogeochemical cycles of carbon and nutrients. Plankton diversity is …

Choanoflagellates have three distinctive claims to fame: they are the closest, living,
unicellular relatives of animals; they are a major component of aquatic microbial foodwebs; …

The data on the ciliates species composition are given for the Baltic Sea, a brackish-water
semi-closed water body where a considerable part of the planktonic fauna is presented by …

Phytoplankton and heterotrophic bacteria are key groups at the base of aquatic food webs.
In estuaries receiving riverine water with a high content of coloured allochthonous dissolved …

We analysed long-term monitoring data from 1979 to 2012 in the Gulf of Bothnia, the
northernmost extension of the Baltic Sea, to examine changes in the summer food web …

Despite cyanobacteria being a key phytoplankton group in the Baltic Sea, the factors
governing their community structure are still poorly understood. Here, we studied the …

Marine bacterioplankton are essential in global nutrient cycling and organic matter turnover.
Time-series analyses, often at monthly sampling frequencies, have established the …

Detailed organic geochemical analyses were performed on surface water particulate
samples of the lower Kalix River and northern Bothnian Bay collected during the spring flood …

Heterotrophic flagellates (HF) play an essential function in the microbial food loops as it is
an agent of biochemical cycling of limiting nutrients and being a useful bio-indicator of …
