“…Variation in microclimate within dead wood can therefore have pronounced effects on the fungal community (Boddy & Heilmann-Clausen, 2008;Pouska, Macek, Zíbarová, & Ostrow, 2017). However, current results are inconsistent, and both negative Horák et al, 2016) and neutral effects of the microclimate on species richness have been reported. Second, the amount and heterogeneity (e.g.…”

“…Species richness, in contrast to the community composition, was not significantly affected by canopy openness (Table ). Some of the few existing studies have suggested that canopy openness reduces the number of species (Bässler, Müller, et al., ; Horák et al., ) and another reported no effect (Bässler et al., ). One explanation for the conflicting results might be that these studies were based on survey data, in which important drivers of species richness were either unknown or correlated, which leads to confounding effects.…”

“…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.

The structure of forests is an important stabilizing factor regarding ongoing global climate and land use change. Biodiverse mountain forests with natural structure are one of the ecosystems most endangered by these problems. We focused on the mountain forest islands of European beech (Fagus sylvatica) and their role in the natural distribution of organisms. The study area was situated in the oldest Czech national park, Krkonoše (385 km2), which is the highest mountain ridge in the country. We studied multi-taxa (lichens, beetles and hymenopterans) responses to three hierarchical spatial levels of the environment: the topography was described by the elevation gradient; the patch structure was described by canopy openness, dead wood amounts, and Norway spruce (Picea abies) cover; and the tree level was described by species of the sampled tree and its diameter. Lichens preferred higher elevations, while insect groups responded conversely. Furthermore, insect groups were mainly influenced by the inner patch structure of beech islands. Lichens may be jeopardized due to the predicted future increase in temperatures, since they would need to shift toward higher altitudes. Insects may be mainly threatened in the future by land use changes (i.e., forest management) – as indicated by an interconnection of canopy openness and the amount of dead wood.

“…According to Baselga's (2008) observations, species diversity could mostly be expounded by a temperature gradient eliciting a decreasing diversity gradient along the south-to-north axis. Additionally, some recent studies (Lacasella et al 2015;Horák et al 2016) have demonstrated that major factors of the presence/activity of the adults of Cerambycidae in a given area depends on the landscape structure (forest border, gap size in canopy, presence of flowers etc. ).…”

Keszthelyi S., Pónya Z., Pál-Fám F. (2017): Climate-induced seasonal activity and flight period of cerambycid beetles in the Zselic forests, Hungary. J. For. Sci., 63: 503-510.The longhorn beetle fauna (Coleoptera: Cerambycidae) was studied in the Zselic region (Somogy county) in Hungary in seven consecutive years (2009)(2010)(2011)(2012)(2013)(2014)(2015). In total 2,931 specimens were observed and the presence of 83 species was identified during the sampling period. The most abundant species were: Plagionotus arcuatus (Linnaeus, 1758) (p i = 10.542); Cerambyx scopoli Füssli, 1775 (p i = 8.359), Dorcadion aethiops (Scopoli, 1763) (p i = 6.653) and Strangalia melanura (Redtenbacher, 1867) (p i = 6.209). According to our examinations, individual meteorological factors, particularly temperature, directly influenced the dispersal and the activity of longhorn beetles (P = 0.038) as well as the species richness (P = 0.047), as did weather systems formation and movement of air masses, cold and warm fronts. It is also shown that the activity of the insects is influenced by daily weather conditions. The activity of arthropods was higher during warm, dry days and less pronounced during cold, wet ones coupled with high air pressure values. A conspicuous relationship was observable between the appearance of cerambycid beetles and their time period. According to the results of Principal Coordinate Analysis four major groups can be distinguished: early-flight, late spring-flight, summer-flight and late-flight species.
