“…Isothermality may therefore bene t fungal communities by providing a stable, predictable environment in which to grow and reproduce. This is particularly true for fungal symbionts that live in association with plants or other organisms, where temperature stability can help to maintain the delicate balance of the symbiotic relationship [53,54]. At the same time, isothermality may also limit the range of fungal communities that can exist in a given environment.…”

Background Lichens are symbiotic organisms composed of a fungus and a photosynthetic partner, which are key ecological bioindicators due to their sensitivity to environmental changes. The endolichenic fungi (ELF) living inside lichen thalli, are an important but understudied component of playing crucial ecological roles such as nutrient cycling and protection against environmental stressors. Therefore ELF community investigation is vital for fostering sustainable ecosystems and leveraging their ecological benefits. Deciphering the intricate relationships between ELF and their lichen hosts, alongside the influence of environmental factors on these communities, presents a significant challenge in pinpointing the underlying drivers of community structure and diversity.Results Our research demonstrated that locational factors were the main drivers of the ELF community structure, rather than host haplotype. Several climatic factors affected the diversity of the ELF community and contributed to the prevalence of different types of fungal residents within the ELF community. A decrease in isothermality was associated with a greater prevalence of pathotrophic and saprotrophic fungi within the ELF community, resulting in an overall increase in community diversity. By conducting a structural equation modeling analysis, we identified a robust link between climatic variables, fungal trophic mode abundance, and the species diversity of the ELF community.Conclusion This study's discoveries emphasize the significance of examining climate-related factors when investigating ELF's structure and function. The connection between fungi and climate is intricate and complex, and can be influenced by various other factors. Investigating the potential for ELF to adapt to changing climatic conditions, as well as the potential effects of changes in ELF communities on lichen function, would be valuable research areas. We anticipate that our research results will establish a basis for numerous future ELF research projects and have a significant impact on the field.

“…In the WoS, databases used for our search included the WoS Core Collection, Current Contents Connect, KCI‐Korean Journal Database, MEDLINE and SciELO Citation Index. We also checked the reference lists of relevant meta‐analyses to obtain target articles (Alberton et al, 2005; Duarte & Maherali, 2022; Kivlin et al, 2013; Marro et al, 2022). To avoid bias, the following criteria were used to screen studies: (1) Inoculated and non‐inoculated groups must be the same except for the factor of AMF inoculation.…”

Land plants play a key role in global carbon cycling, but the potential role of arbuscular mycorrhizal fungi (AMF) in the responses of a wide range of plant species to global change factors (GCFs) remains limited. Based on 1100 paired observations from 181 plant species, we conducted a meta‐analysis to test the role of AMF in plant responses to four GCFs: drought, warming, nitrogen (N) addition and elevated CO2. We show that AMF significantly ameliorate the negative effects of drought on plant performance. The GCFs N addition and elevated CO2 significantly enhance the performance of AM plants but not of non‐inoculated plants. AM plants show better performance than their non‐inoculated counterparts under warming, although neither of them showed a significant response to this GCF. These results suggest that AMF benefit plants in response to GCFs. Our study highlights the importance of AMF in enhancing plant performance under ongoing global change.
