Uptake and loss of carbon,. by a plant depends on the specific activity of its leaves and the total amount (mass or area) of leaves present per total plant mass. Leaf photosynthesis depends on three processes: (1) the diffusion of CO. from the free atmosphere to the site of carboxylation in chloroplasts, (2) the biochemical

Growth dynamics and phenology,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)

Cell division and tissue formation,ctive phase of life and sufficient carbon assimilates are present at meristems, plants would grow new cells. But this is not necessarily so. The formation of new cells involves a suite of synthetic steps, all potentially as sensitive, or even more so, to low temperature than the production of the ra

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 vegetation Figure 10.2.

https://doi.org/10.1007/978-94-007-5684-7explore. Palaeorecords suggest that life on land started out in sheltered, warm and moist environments, and gradually expanded into more demanding habitats where water is rare, thermal energy is either low or overabundant or where mechanical disturbance is high. More than 100 million years ago, when
