“…Therefore, it seems that large productivity is confined to those years when climatic conditions are more optimal. Thus, when late-summer and early-autumn precipitation and temperature are optimal, fungal species produce sporocarps in abundance47. Based on our results, this seems to be at least every 5–7 years.…”

“…In any case, the inexistence of an elevational effect over the whole biomass production does not mean a lack of elevational effect when biomass is split in different genera or groups of species, as was demonstrated in previous works for edible mushrooms production in similar areas37. This suggests that increasing the accuracy in epigeous sporocarp yield modelling may require approaches that consider individual fungal species or groups with similar features (functional groups) instead of using the whole sporocarp community47.…”

Mushrooms are important non-wood-forest-products in many Mediterranean ecosystems, being highly vulnerable to climate change. However, the ecological scales of variation of mushroom productivity and diversity, and climate dependence has been usually overlooked due to a lack of available data. We determined the spatio-temporal variability of epigeous sporocarps and the climatic factors driving their fruiting to plan future sustainable management of wild mushrooms production. We collected fruiting bodies in Pinus sylvestris stands along an elevation gradient for 8 consecutive years. Overall, sporocarp biomass was mainly dependent on inter-annual variations, whereas richness was more spatial-scale dependent. Elevation was not significant, but there were clear elevational differences in biomass and richness patterns between ectomycorrhizal and saprotrophic guilds. The main driver of variation was late-summer-early-autumn precipitation. Thus, different scale processes (inter-annual vs. spatial-scale) drive sporocarp biomass and diversity patterns; temporal effects for biomass and ectomycorrhizal fungi vs. spatial scale for diversity and saprotrophic fungi. The significant role of precipitation across fungal guilds and spatio-temporal scales indicates that it is a limiting resource controlling sporocarp production and diversity in Mediterranean regions. The high spatial and temporal variability of mushrooms emphasize the need for long-term datasets of multiple spatial points to effectively characterize fungal fruiting patterns.

“…Both the timing and production of fruit bodies have been linked to yearly variation in temperature and rainfall (Krebs et al, 2008;Boddy et al, 2014). There is evidence from previous studies that lagged weather influences on fungal fruiting can be important, for example temperature in previous months or years (Krebs et al, 2008;Ágreda et al, 2016). To narrow down the large possible range of weather related variables to a set of testable models, three hypotheses were derived regarding the timing of weather conditions and occurrence of stipitate hydnoid fruit bodies:…”

A definitive version was subsequently published in Fungal Ecology (2017), 27 (A). 137-140. 10.1016/j.funeco.2017.03 Main textThe occurrence and abundance of fungal fruit bodies are variable under natural conditions. Where surveys have been conducted in the same area over multiple years, many species are not observed in all years (Sato et al., 2012) and there is often large variation in the number of fruit bodies produced when fruiting does occur (Straatsma et al., 2001; Pilz et al., 2006). It is important to understand the drivers of fruit body production because the presence or absence of fruit bodies is the primary measure used to determine the conservation status of fungi. Stipitate hydnoid fungi are ectomycorrhizal fungi which are considered to be rare in the United Kingdom based on infrequent observation of fruit bodies and evidence of declining occurrence across Europe (Newton et al., 2002). It has been noted that these fungi produce fruit bodies sporadically, with sometimes several years between fruit body records (van der Linde et al., 2012).Using molecular identification techniques it has been shown that stipitate hydnoid fungi can be present and active belowground and not fruit for several years (van der Linde et al., 2009Linde et al., , 2012 Gordon & Van Norman, 2014). This suggests that, for stipitate hydnoids, the sporadic fruiting patterns may be explained by variation in fruit body production between years, rather than rapid turnover of populations.One potential driver of interannual variation in fruit body production is weather. Both the timing and production of fruit bodies have been linked to yearly variation in temperature and rainfall (Krebs et al., 2008; Boddy et al., 2014). There is evidence from previous studies that lagged weather influences on fungal fruiting can be important, for example temperature in previous months or years (Krebs et al., 2008; Ágreda et al., 2016).

“…In this study, we have used data from P. sylvestris and P. pinaster stands because these pine species are monitored for mushroom yield from permanent plots established in different locations of northern Spain, which is a consequence of the importance of both pine species in terms of their wide distribution range and mushroom production in the Iberian Peninsula. Previous works have shown that climatic factors are key for controlling the yields of mushrooms (Kauserud et al 2008;Ágreda et al 2016;Alday et al 2017b;Karavani et al 2018). Wet and warm autumns seem to promote ectomycorrhizal fungi yields in Spanish pine forests (Martínez-Peña et al 2012;Taye et al 2016;Alday et al 2017a;).…”

Yield models for predicting aboveground ectomycorrhizal fungal productivity in Pinus sylvestris and Pinus pinaster stands of northern Spain

et al. 2019

Background: Predictive models shed light on aboveground fungal yield dynamics and can assist decision-making in forestry by integrating this valuable non-wood forest product into forest management planning. However, the currently existing models are based on rather local data and, thus, there is a lack of predictive tools to monitor mushroom yields on larger scales. Results: This work presents the first empirical models for predicting the annual yields of ectomycorrhizal mushrooms and related ecosystem services in Pinus sylvestris and Pinus pinaster stands in northern Spain, using a long-term dataset suitable to account for the combined effect of meteorological conditions and stand structure. Models were fitted for the following groups of fungi separately: all ectomycorrhizal mushrooms, edible mushrooms and marketed mushrooms. Our results show the influence of the weather variables (mainly precipitation) on mushroom yields as well as the relevance of the basal area of the forest stand that follows a right-skewed unimodal curve with maximum predicted yields at stand basal areas of 30-40 m 2 •ha − 1. Conclusion: These models are the first empirical models for predicting the annual yields of ectomycorrhizal mushrooms in Pinus sylvestris and Pinus pinaster stands in northern Spain, being of the highest resolution developed to date and enable predictions of mushrooms productivity by taking into account weather conditions and forests' location, composition and structure.
