Environmental changes have a manifold effect on biodiversity. Although soil harbours most
terrestrial biodiversity (Anthony et al., 2023), including c. 90% of the fungal kingdom, little is …

Ectomycorrhizal (ECM) fungi serve key functions in forest ecosystems by supplying water
and nutrients to tree hosts, yet mutualistic plant–fungi interactions are jeopardised by …

A key component of biodiversity is the number and abundance of individuals (ie genotypes),
and yet such intraspecific diversity is rarely considered when investigating the effects of …

Plant range boundaries are generally considered to reflect abiotic conditions; however, a
rise in negative or decline in positive species interactions at range margins may contribute to …

Multispecies mutualisms, such as the association between trees and ectomycorrhizal fungi,
are often shaped by environmental context. Here, we explored the functional mechanisms …

Contents Summary 1122 I. Introduction 1122 II. Are there consistent patterns in diversity of
mycorrhizal fungal genotypes and species across space? 1125 III. What is the variation in …

Studies on ectomycorrhizal fungi (EcMF) populations, their genetic diversity, dynamics and
the ecological drivers of their structure have long struggled with characterisation of fungal …

Three papers in this issue of New Phytologist deal with the vertical distribution of
ectomycorrhizal fungi in soils. Anderson et al.(pp. 1423–1430) analyze an earlier dataset …

In the hyperdiverse fungi, the process of speciation is virtually unknown, including for the>
20 000 species of ectomycorrhizal mutualists. To understand this process, we investigated …

Ectomycorrhizal (ECM) fungi are among the most diverse and dominant fungal groups in
temperate forests and are crucial for ecosystem functioning of forests and their resilience …
