It integrates published and unpublished data from alpine streams in Austria and in the Trento Province (Northern Italy). The main focus is on the structural and taxonomic composition of benthic algae including macro- and micro-algae and their contribution to the epilithic biofilm and the stream food-web. The environmental conditions relevant to algae within the two major stream types, the glacial (glacier-fed) and non-glacial krenal (spring-fed) stream are discussed. The paper considers both the maximum possible structural complexity of transverse algae zonation in cascading alpine/subalpine stream segments, and the effects of glacial water on species richness in the Central Alps in Austria. Autecological data are given for 46 common diatoms from 42 sites in the Central Eastern and Southern Central Alps and for 30 algae in addition to diatoms for 22 streams in the Central Eastern Alps. Since data on responses of benthic algae to the harsh conditions in high altitude Alpine streams are very scarce, results from literature and the author’s experiences from these and other mountain stream types are synthesized to formulate major objectives for future research in benthic high altitude Alpine stream ecology.

However, prioritisation methods are impeded by insufficient knowledge on the distribution and conservation status of freshwater taxa, particularly invertebrates. We evaluated the extinction risk of the world’s 590 freshwater crayfish species using the IUCN Categories and Criteria and found thirty two percent of all species are threatened with extinction. The level of extinction risk differed between families, with proportionally more threatened species in the Parastacidae and Astacidae than in the Cambaridae. Four described species were Extinct and 21% were assessed as Data Deficient. There was geographic variation in the dominant threats affecting the main centres of crayfish diversity. The majority of threatened US and Mexican species face threats associated with urban development, pollution, damming and water management. Converse...

Accordingly, most of the today temperate freshwater fauna in this area has become established within the last 10,000–15,000 years, a process that has not yet stopped. Although prehistoric man had already favoured the distribution of various plant and animal species, a considerable change in species distributions started with the onset of the great expeditions and continued with the subsequent alterations of the cultural landscape. Predominantly, plant species were transported to Europe and with them various species of animals and fungi arrived. In addition to the intentional introductions, many species were transferred to European fresh waters accidentally. The general decline of species diversity in many types of ecosystems has been a result of all these activities in central Europe. This is expected to be intensified, leading to a drastic increase of non-indigenous species (NIS).

The role of habitat structure on the community composition was studied with a particular focus on the spring-dwelling animals colonizing the aquatic and the adjacent aquatic-terrestrial transition zones. The crenocoenosis was predominantly composed of Chironomidae, Plecoptera, Trichoptera, Mollusca and Ostracoda and the number of spring-specialists was high. Habitat complexity, variable microhabitat composition and the concomitance of lotic and lentic areas in the eucrenal zone furthered a high species diversity and abundance. Even the aquatic-terrestrial transition zone was inhabited by high numbers of crenobionts and crenophiles. Moreover, the connectivity of aquatic and terrestrial habitats positively affected the structural and functional organisation of invertebrate assemblages in the spring biotopes.
