Alpine soils,distances one can find a large variety of alpine soil types, ranging from alpine sand drifts to peat bogs, from shallow A/C (e.g. rendzina) soils to the deeply weathered profiles of some alpine grassland soils. Vegetation mosaics closely follow these below-ground patterns as was documented in a firs

Alpine treelines, beyond which massive single stems and tall crowns either can not be developed, become unaffordable or are disadvantageous (Fig. 7.1). Why do trees disappear above a certain elevation, what causes the alpine zone to be treeless, i.e. “alpine”? The answer to this question would also indicate which fu

Water relations,hortage does occur, and contributes to the overall impact of the physical environment on mountain plants (Fig. 9.1). In this chapter I will first discuss the overall hydrological situation, the land area based water balance and soil moisture at alpine altitudes — aspects which have strong links with

Mineral nutrition,t spatial scales of one to a few meters and can be quite extreme, as illustrated by Figure 10.1. In regions with traditional alpine cattle farming such as the Alps, a multitude of unintended “fertilizer experiments” demonstrate how local nutrient addition (redistribution) can influence alpine vegeta

Growth dynamics,roots rather than stems, but the biomass fraction invested in leaves is the same as in comparable morphotypes at low altitude. However, interspecific variation in these traits is far greater than the mean elevational difference for communities. Non-structural carbon compounds (carbohydrates, lipids)

Plant biomass production,placed in the context of interactions, the growth of many other leaves and plants. A slowing down of one individual may be balanced by enhanced growth of another, hence only a consideration of all members of a plant community will reveal what may be the typical biomass production for a certain envir
