Abstract: Gradients in species diversity across elevations and latitudes have fascinated biologists for decades. While these gradients have been well documented for macroorganisms, there is limited consensus about their universality, shape and drivers for microorganisms, such as fungi, despite the importance of fungal diversity for ecosystem functions and services. We conducted a comprehensive survey of fungal species richness in forests across 17 elevational transects along a latitudinal gradient covering the continental scale of Europe. Diversity patterns along elevational and latitudinal gradients differed among fungal ecological guilds. Diversity of saprotrophs declined with elevation while ectomycorrhizal (ECM) fungal diversity peaked in mid-elevations. Moreover, the diversity of root endophytic fungi increased with latitude but did not change with elevation. Bayesian species distribution modeling suggests that fungal diversity is structured by deterministic rather than stochastic drivers. Importantly, ECM fungal diversity pattern persists even after accounting for the effects of environmental conditions. These results suggest that environmental conditions differentially shape the diversity of fungal guilds along elevational and latitudinal gradients, but this goes beyond soil and climatic factors in the case of ECM fungi. This study paves the way toward a better understanding of fungal diversity gradients across elevations and latitudes, with possible implications for macroecological theory, conservation and management.

Ectomycorrhizal symbionts of silver fir (Abies alba Mill.) in Slovenia
Tina Unuk Nahberger, Hojka Kraigher, Tine Grebencs, 2024, original scientific article

Abstract: Ectomycorrhizal symbionts of silver fir have been in Slovenia rarely analyzed and identified, thereby little is known about their diversity and distribution across Slovenia. The aim of this study was to identify ectomycorrhizal fungal symbionts of silver fir in silver fir natural distribution area in Slovenia. Ectomycorrhizal fungi were identified based on morphological and anatomical descriptions and by ITS DNA barcoding. Altogether we identified 86 different ectomycorrhizal symbionts of silver fir, many of them were in symbiosis with silver fir, in our study identified for the first-time. The most abundant ECM fungal taxa were assigned to Russula, Tomentella and Lactarius genus.
