Evidence for a non-linear carbon accumulation pattern along an Alpine glacier retreat chronosequence in Northern Italy.

ABSTRACT:

Background

The glaciers in the Alps, as in other high mountain ranges and boreal zones, are generally retreating and leaving a wide surface of bare ground free from ice cover. This early stage soil is then colonized by microbes and vegetation in a process of primary succession. It is rarely experimentally examined whether this colonization process is linear or not at the ecosystem scale. Thus, to improve our understanding of the variables involved in the carbon accumulation in the different stages of primary succession, we conducted this research in three transects on the Matsch glacier forefield (Alps, N Italy) at an altitude between 2,350 and 2,800 m a.s.l.

Methods

In three field campaigns (July, August and September 2014) a closed transparent chamber was used to quantify
