Animal Diversity at High Altitudes in the Austrian Central Alpsigh Alps have been studied for more than 100 years (Bäbler 1910; Franz 1943; Holdhaus 1954; Janetschek 1956,1993; Schmölzer 1962; Janetschek et al. 1987). A special fauna is found in the forefield of glaciers (Janetschek, 1949) and at the glacier surface itself. To survive under high alpine conditio

Direct and Indirect Effects of Plant Species on Biogeochemical Processes in Arctic Ecosystems/or trophic interactions. Indeed, species’ distributions in arctic ecosystems are quite sensitive to the environmental parameters expected to change in northern ecosystems such as temperature (Chapin and Shaver 1985b; Havstrom et al. 1993), hght (op cit.), nutrient availability (Chapin and Shaver 19

Patterns and Causes of Arctic Plant Community Diversity; Whittaker 1965). Questions of the functional significance of diversity, and indeed whether species diversity alone has any functional significance, are also abundant (e.g. Hurlbert 1971; May 1973; Schulze and Mooney 1993). The taxonomic and genetic diversity within a community, the diversity among

Causes of Arctic Plant Diversity: Origin and Evolution (Wilson 1988), yet the study of biodiversity is the oldest branch of biology (Weber and Wittmann 1992). Today, frames of reference other than taxonomic ones have become important as we recognize the need for understanding diversity at various levels of organization, from inclusive to restrictive, f

Alpine Plant Diversity: A Global Survey and Functional Interpretationsdra and “alpine vegetation” are the absence of trees, the short stature of plants, and the low annual mean temperature. Most other components of the alpine environment may differ substantially from arctic tundra environments (Table 1; Bilhngs 1973, 1979a). The term “alpine” is used here exclusively
