Protists Eukaryotic microorganisms that are neither animal, fungi, plant, or archaean. Unicellular forms include the amoeboid protozoans and algae, such as the foraminferans and radiolarians, and dinoflagellates and diatoms, respectively. Some algae are either multicellular or colonial, such as the red algae and freshwater Volvox, respectively.

The goal of this chapter is to summarize the composition and community patterns of algae (with special consideration to benthic diatoms), zoobenthos, and fish that occur in Alpine freshwaters. The data presented are a synthesis of published research and represent the current state of knowledge on the different groups. The chapter closes with a general perspective on the biodiversity of alpine freshwaters. 

The most frequently occurring diatom in Alpine freshwaters is Achnanthidium minutissimum. This species is also abundant in other high-altitude regions of Europe, Himalayas, Andes, Rocky Mountains and Lapland [18, 34, 45 7]. It is a...

In spite of his devotion to organic and inorganic chemistry, Cleve never lost interest in biology. During bis later years he made an extended study of the plankton of Skagerak and the North Sea, especially of the freshwater algae and diatoms, in order to locate the ocean currents.
