About 40 years have passed since the discovery of picophytoplankton; the present
knowledge of the taxonomy physiology and ecology of these tiny photoautotrophic cells …

Phytoplankton life forms, including unicells, colonies, pseudocolonies, and multicellular
organisms, span a huge size range. The smallest unicells are less than 1 µm3 (eg …

Acquisition of phototrophy is widely distributed in the eukaryotic tree of life and can involve
algal endosymbiosis or plastid retention from green or red origins. Species with acquired …

This chapter deals with some taxonomic and ecological aspects of picocyanobacteria (Pcy)
single-cells, microcolonies and other colonial (CPcy), that are common in lakes throughout …

Many ciliates acquire the capacity for photosynthesis through stealing plastids or harboring
intact endosymbiotic algae. Both phenomena are a form of mixotrophy and are widespread …

Grazing by the planktonic phytoflagellate, Pyramimonas gelidicola McFadden (Chlorophyta:
Prasinophyta), and heterotrophic nanoflagellates (HNAN) in meromictic saline Ace Lake in …

We measured biomass and primary production of picophytoplankton (PicoPhy: 0.2–2 μm)
and of autotrophic size fraction> 2 μm in six deep ultraoligotrophic lakes in the Andean …

Picocyanobacteria (Pcy) single-cells and microcolonies are common in lakes throughout the
world, and abundant across a wide spectrum of trophic conditions. The single-celled Pcy …

This study showed first results on the geographical distribution of mixotrophic ciliates of the
genus Stentor in the Chilean North Patagonian Lake District. Thirteen deep North …

Receding glaciers are among the most obvious changes caused by global warming, and
glacial meltwater entering lakes generally forms plumes of particles. By taking vertical …
