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...

Several plants A6-desaturase genes have been cloned from Anemone leveillei, borago [211], three Echium species, Marchantia polymorpha. Primula farcinosa, P. vialii and P. juliae, as well as from fungi Mortierella alpine, M. isabelina, Mucor rouxii [205] and Pythium irregulare, from the diatom Phaeodactylum tricornutum [203] and from mosses the Ceratodom purpureus and Physcomitrella patens [212], although not all of them have been expressed in plants.
