“…Not surprisingly, numbers of species dependent on dead wood increase, e.g. saproxylic beetles (Müller et al, 2008) and epixylic lichens (Bässler et al, 2016;Moning et al, 2009). Interestingly, the number of species of wood-inhabiting fungi can be higher in mature vital spruce stands because successional pathways of beetle-killed stands benefit a small distinct set of species (Bässler et al, 2016;Beudert et al, 2015).…”

“…Among environmental conditions, stand microclimate and the amount and heterogeneity of dead wood in the surroundings seem to be of particular importance. First of all, numerous studies have shown that the diversity of wood‐inhabiting fungi is correlated with canopy openness—a proxy for microclimate conditions (Bässler et al., ; Bässler, Müller, Dziock, & Brandl, ; Horák, Kout, Vodka, & Donato, ; Lehnert, Bässler, Brandl, Burton, & Müller, ). This correlation is not surprising as forest gap dynamics caused by anthropogenic disturbances, for example, logging, or natural disturbances, for example, windthrows, insects, fire or snow, is an important driver influencing the diversity of forest species across numerous taxa at the landscape scale (Swanson et al., ).…”

Independent effects of host and environment on the diversity of wood‐inhabiting fungi

Dead wood is a habitat for numerous fungal species, many of which are important agents of decomposition. Previous studies suggested that wood‐inhabiting fungal communities are affected by climate, availability of dead wood in the surrounding landscape and characteristics of the colonized dead‐wood object (e.g. host tree species). These findings indicate that different filters structure fungal communities at different scales, but how these factors individually drive fungal fruiting diversity on dead‐wood objects is unknown. We conducted an orthogonal experiment comprising 180 plots (0.1 ha) in a random block design and measured fungal fruit body richness and community composition on 720 dead‐wood objects over the first 4 years of succession. The experiment allowed us to disentangle the effects of the host (beech and fir; logs and branches) and the environment (microclimate: sunny and shady plots; local dead wood: amount and heterogeneity of dead wood added to plot). Variance partitioning revealed that the host was more important than the environment for the diversity of wood‐inhabiting fungi. A more detailed model revealed that host tree species had the highest independent effect on richness and community composition of fruiting species of fungi. Host size had significant but low independent effects on richness and community composition of fruiting species. Canopy openness significantly affected the community composition of fruiting species. By contrast, neither local amount nor heterogeneity of dead wood significantly affected the fungal diversity measures. Synthesis. Our study identified host tree species as a more important driver of the diversity of wood‐inhabiting fungi than the environment, which suggests a host‐centred filter of this diversity in the early phase of the decomposition process. For the conservation of wood‐inhabiting fungi, a high variety of host species in various microclimates is more important than the availability of dead wood at the stand level.

“…This might be due to the generally impoverished number of species in the studied area -only 17, compared to 68 species observed in a similar study in eastern Finland (Sippola et al 2001). The low polypore diversity may be due to lack of past temporal continuity of substrate (Siitonen 2001) due to removal of dead trees, which was suggested by the low (Bässler et al 2016). Polypore utilization of logs generally occurs from initial bark loss to the stage of wood softening (Kruys et al 1999), corresponding to decay stage 3.…”

Coarse woody debris (CWD), which is in low supply in intensively managed forest, is an essential habitat for many species of bryophytes, fungi and insects. We investigated richness of bryophyte and polypore species on CWD of Norway spruce Picea abies (L.) Karst. in relation to CWD type, size, decay stage and age since mortality. We also identified indicator species for the bryophyte and polypore communities on dead trees in various decay stages. CWD age since mortality was determined to assess the time period of potential colonization by the indicator species. The study was conducted in Latvia, located in the hemi-boreal forest zone, where such information was generally lacking. The larger part of spruce CWD was in early decay stages, due to the legacy of forest management and recent disturbance events. The maximum age of spruce CWD was 48 years, and age of the majority of CWD pieces in advanced decay stages was 20 to 40 years. The estimated ages of CWD suggest a more rapid decay rate in the mesotrophic habitat studied in the Eastern Baltic region than reported previously for northern Scandinavia and mountainous regions. Bryophyte species richness was significantly affected by CWD diameter, type (higher on snapped logs) and decay stage (lowest in initial decay stage). Polypore species richness was significantly lower on snags, and higher on logs in early decay stages. A succession of epixlyic species was shown from common polypore species Fomitopsis pinicola and Trichaptum abietinum at start of wood decay to indicator bryophytes like Nowellia curvifolia in early decay stages after loss of bark, Lepidozia reptans and Jamesoniella autumnalis in mid stages and Herzogiella seligeri with epigeous species in late decay stages.
