“…Branches in DC2 have been on the forest oor for many years, as opposed to branches in DC1 which belonged to recently fallen trees; hence, the slightly lower density of branches in DC2 in MF forest could be related to factors that accelerated decomposition or produced faster degradation of some component in the rst years after intervention but are no longer operating. The reason why mass loss of twigs in DC2 did not differ between treatments could be that, because of their very small diameter, the twigs reaching the forest oor at the same time as branches in DC2 should have been almost totally decomposed by the beginning of the study (Gallo et al 2019); thus, the twigs in DC2 used in the experiment must have reached the forest oor later than the branches in DC2.…”

“…Previous studies in shelterwood systems in these forests have reported lower humidity and greater radiation and wind speed in managed forests than in unmanaged ones (Caldentey et al 1999;Promis et al 2010). Although litter and wood decomposition in these forests has been documented in several studies (Frangi et al 1997;Decker and Boerner 2006;Ibarra et al 2011;Mansilla 2012;Moretto and Martínez Pastur 2014;Gallo 2017;Gallo et al 2019) and wood-inhabiting fungi diversity has also been reported (Horak 1979;Greslebin 2002;Greslebin and Rajchenberg 2003;Rajchenberg 2006), no studies have assessed wood decomposition in relation to fungal diversity and forest management.…”

Fungal diversity, woody debris, and wood decomposition were assessed in Nothofagus pumilio forests with and without forest management. A plot in a managed forest (MF) and a plot in an unmanaged control forest (C) were established in three sites in Chubut, Argentina. On each plot, forest structure, volume of woody debris, temperature, and humidity were recorded. Basidiomata of aphyllophoroid fungi were recorded in the fall and spring for 2 years. A decomposition assay with branches and twigs in two decay classes (DC) was established, and mass loss was measured after 3 and 2 years of eld incubation respectively. To evaluate fungal diversity and mass loss within MF and C, generalized linear mixed-effects models (GLMM) were performed. Neither richness nor abundance differed between treatments, and community composition was similar. Only branches in DC2 showed greater mass loss in MF than in C. The volume of CWD was greater in MF and had a positive effect on fungal richness. A few aphyllophoroid species showed signi cant differences in abundance between treatments. Forest management in the conditions evaluated did not generate evident changes in fungal diversity, nor in wood decomposition. However, the differences observed in mass loss of DC2 could indicate that there were some factors operating in the past, that are no longer seen in the present, which may have accelerated decomposition. This highlights the need for studies evaluating changes in canopy cover, microclimate and fungal community, including potential key species, over a period starting just after the forest management.
