“…It is important to note that we can refine this trend and pinpoint the importance of temperate evergreen (coniferous) forests, compared to temperate deciduous broadleaf forests, as harbingers of high fungal richness. Because management can impact forests beyond what we have demonstrated here (Paillet et al, 2010;Spake et al, 2016;Dvořák et al, 2017;Mair et al, 2018), studies regarding the interactions between management and forest types can clarify an area that is of clear importance for fungal diversity.…”

“…Often, only single, static time‐period measures are available to link up current conditions with the biological data; these measures lack the dynamism (daily to annual variability) that is key to our understanding, given that we are accelerating climate change and grossly modifying the landscape (Holyoak and Heath, ). For example, urbanization and forest management each impact biodiversity (Paillet et al., ; Dvořák et al., ), with interactions between land‐use change and climate (Mair et al., ) as well as tree species diversity (Spake et al., ). Likewise, climate affects assemblages of fungi, which consequently impacts phenological patterns (Talbot et al., ; Andrew et al., , b).…”

Premise of the Study Fungal diversity (richness) trends at large scales are in urgent need of investigation, especially through novel situations that combine long‐term observational with environmental and remotely sensed open‐source data. Methods We modeled fungal richness, with collections‐based records of saprotrophic (decaying) and ectomycorrhizal (plant mutualistic) fungi, using an array of environmental variables across geographical gradients from northern to central Europe. Temporal differences in covariables granted insight into the impacts of the shorter‐ versus longer‐term environment on fungal richness. Results Fungal richness varied significantly across different land‐use types, with highest richness in forests and lowest in urban areas. Latitudinal trends supported a unimodal pattern in diversity across Europe. Temperature, both annual mean and range, was positively correlated with richness, indicating the importance of seasonality in increasing richness amounts. Precipitation seasonality notably affected saprotrophic fungal diversity (a unimodal relationship), as did daily precipitation of the collection day (negatively correlated). Ectomycorrhizal fungal richness differed from that of saprotrophs by being positively associated with tree species richness. Discussion Our results demonstrate that fungal richness is strongly correlated with land use and climate conditions, especially concerning seasonality, and that ongoing global change processes will affect fungal richness patterns at large scales.

“…This variable was calculated taking into account two assumptions: (i) one of the main old-growth forests characteristics is the presence of dead wood in large volumes [BRUNET & al. 2010;DVOŘÁK & al. 2017]; the main reason behind this is represented by the protective status of those forests, as silvicultural measures tend to keep dead trees on-site [ÇOLAK & al.…”

Coarse woody debris is often highlighted as the most important microhabitat for numerous saproxylic species, including macrofungi. Providing valuable nutrients, stable microclimatic conditions and development space, logs and large branches are considered of great ecological value for macrofungal diversity conservation. Old forests are especially rich in downed coarse dead wood both at quantity and quality level. Unfortunately, these forests are also affected by human interventions, through wood extraction and forest fragmentation. The main objective of this study was to find the factors that best explain the macrofungal diversity on downed coarse woody debris (DCWD). For this, we sampled 21 plots in forests dominated by beech or oak from Northeastern Romania, where we collected data about fungi, forest structure, and dead wood. We completed the variables set with forest fragmentation and topographic indices. In order to find the best models and predictors, we used generalized linear models (GLM). We found 163 taxa, polypores and agarics being the most frequent. The two most important predictors had a positive effect, increasing macrofungal diversity: 2'nd and 3'rd decay stages DCWD volume and elevation while the third one had a hump-shape effect on diversity. In old forests, downed dead wood quality and quantity is a vital component for numerous species of fungi to survive and develop. Elevation is a known proxy of macroclimatic conditions, furthermore creating new richresources niches because increasing humidity and taxonomic diversification by conifers occurrence. Patch shape can have divergent effects on fungi, as increasing perimeter is associated from one point on, with human deforestation and accessibility. Overall, we believe that Northeastern Romania's old forests hosts a great lignicolous macrofungal richness, which will be protected through silvicultural practices such as keeping valuable dead wood on site.

Lignicolous fungi plays are a vital part of forest ecosystems in Europe. They are involved in Carbon cycle, through decay processes of woody debris. Very fine woody debris (VFWD) forms an important component of this dead wood, being found in any forest in the World. Among European and Romanian forests, Fagus spp. dominating forests are the most important broadleaved ecosystems, of great biotic and abiotic complexity. The present distribution of lignicolous fungi is mainly linked to trees distribution. In the context of climate change, European beech forests will also shift in distribution, structure and composition, triggering changes in lignicolous fungal communities and diversity as well. Considering this background, VFWD lignicolous diversity might be a future beech forests climate change indicator. This will bring the necessity of assessing the main climatic factors that are influencing the lignicolous fungal diversity distribution across European beech forests in Romanian's NorthEast Region. In the present study, our findings confirms the fact that macroclimate have a great influence on lignicolous mycodiversity in beech forests. It seems that minimum temperature and Gams Continentality Index explains approximately 48% of the mycodiversity variation. While dropping minimum temperatures and increasing Gams CI values, the lignicolous fungal richness will rise. While minimum temperature of January might be linked to a complex ecological and phonological framework, Gams CI is a known ecological indicator for optimum habitat of beech forests, which in turn influence lignicolous diversity distribution. Those climatic variables might characterize the relation between plants-fungi-climate in the near future, as increasing atmospheric temperatures will manifest at different scales. Thereafter, VFWD mycodiversity might function as a valuable macroclimatic changing indicator.
