Litterfall in two Pyrenean stands of Pinus sylvestris L. under different environmental conditions.
1993
Pausas J.G.
Spanish; Castilian. Litterfall was studied at two Scots pines (Pinus sylvestris L.) stands (Ps1 and Ps2) in the eastern Pyrenees (NE of the Iberian Peninsula). The stands were close together and the climate and the geological substrate were similar. Microenvironmental conditions (aspect, soil depth and stoniness), however, were different. Thus, water availability and sapwood area of Ps1 were lower than Ps2. In contrast, needle production was higher in Ps1. Climatic conditions during the year of study, and also demography of the needles were studied in an attempt to explain the different litterfall pattern.
