We measured the size structure and taxonomic composition of phytoplankton in temperate rivers during base flows of summer to investigate the influence of river size, ambient nutrient concentration, and light availability on potamoplankton community structure. Algal biomass was measured in three size classes (2–20, 20–64, and .64 mm) by microscope enumeration of water samples collected in 31 riv...

Siliceous planktons are valuable indicators of the environmental conditions in both modern and past marine settings. However, contrast to diatoms radiolarians, other siliceous micro- nanoplankton Arctic Ocean have been rarely explored. In this study, silicoflagellates, endoskeletal dinoflagellate Actiniscus pentasterias chrysophyte cysts were investigated one-year mooring sediment trap material...

Phytoplankton biomass, through its proxy, Chlorophyll a , has been assessed at synoptic temporal and spatial scales with satellite remote sensing (RS) for over two decades. Also, RS algorithms to monitor relative size classes abundance are widely used; however, differentiating functional types from RS, as well the assessment of phytoplankton structure, in terms carbon remains challenge. Hence, ...

We investigated the role of a macrograzer (the filter feeding mussel Dreissena polymorpha) in mediating effects of high summer temperatures on the dominant components of natural river plankton (i.e., bacteria, algae, and heterotrophic flagellates) in flow channel experiments. Effects of adaptation (by comparing mussels from a southern and a northern population) and thermal acclimation of the mu...
