We studied the effects of two types of selective thinning on beech stands formed by a shelterwood cut in 1910 — with lower number of crop trees and higher thinning intensity (T1) and higher number of crop trees with lower thinning intensity (T2). The stands were thinned in 1980, 1991 and 2001. Despite a lower stand density after thinning, the annual basal area increments of thinned stands in both thinning periods (1980–1991 and 1991–2002) were around 20% higher compared to those of the control (unthinned) stands. The mean annual basal area increment of dominant trees was 30–56% larger in the thinned plots compared to the control plots. Of 176 initial crop trees in the T1, 72% were chosen again during the last thinning. In the T2, 258 crop trees were chosen in the first thinning, and only 62% of these trees were chosen again during the last thinning. Only crown suppression and diameter classes of crop trees significantly influenced their basal area increment when diameter classes, crown size, crown suppression, and social status were tested. In the thinned stands, the dominant trees are more uniformly distributed if compared to the dominant trees in the control plots. Finally, the herbaceous cover and the species diversity were higher in the thinned plots.RésuméNous avons effectué des recherches sur les effets de deux sortes d’éclaircies sélectives entreprises sur des peuplements de hêtres formés par la coupe d’abri de 1910 : l’une avec un faible nombre d’arbres de place et une grande intensité d’éclaircie (T1), l’autre avec un nombre élevé d’arbres de place et une intensité faible. Ces peuplements ont été éclaircis en 1980, 1991 et 2001. Bien que la surface terrière de ces peuplements ait été réduite, l’accroissement en surface terrière des peuplements éclaircis a été supérieur de 20 % approximativement aux cours des deux périodes séparant les éclaircies (1980–1991 et 1991–2002) à celui des peuplements non éclaircis. L’accroissement moyen en surface terrière des arbres dominants a été de 20 à 56 % supérieur dans les peuplements éclaircis. Soixante-douze % des 176 arbres de place initiaux de la parcelle expérimentale T1, ont de nouveau été désignés lors de la dernière éclaircie. Sur T2, il y avait 258 arbres de place lors de la première éclaircie, et seulement 62 % d’entre eux ont été de nouveau désignés au cours de la dernière éclaircie. Une analyse parallèle de l’influence des classes de diamètre, de la taille et du couvert des houppiers, et du statut social des arbres montre que le couvert et les classes de diamètre des arbres de place exercent une influence marquée sur l’accroissement de leur surface terrière. Dans les peuplements éclaircis, la répartition spatiale des arbres dominants est plus régulière que dans les peuplements non éclaircis. Le couvert de la strate herbacée et la diversité des espèces sont plus importants dans les peuplements éclaircis.

The influence of Pleurotus ostreatus inoculation on wood degradation and on fungal community structure was studied. The experiments were performed on an organically poor fly ash deposit covered with a 10 cm layer of beech wood chips inoculated with P. ostreatus isolate ZIM76. Compared to non-inoculated wood chips, inoculation increased the temperatures and relative humidities and, in the first 6 months, accelerated Klason lignin degradation by 9% and also, after 17 months, increased iron translocation into wood chips by 30%. After 6 months, PCR-DGGE showed 22-28 and 13-21 fungal taxa in non-inoculated and P. ostreatus-inoculated beech chips, respectively. The differences in number of taxa and in the fungal community structure (based on Dice coefficient) between non-inoculated and inoculated wood chips diminished with time. The results indicate that the naturally occurring processes of wood degradation are as efficient as those occurring in sites inoculated with P. ostreatus.
