“…Although many researchers have reported that soil impacts AMF diversity, there is no consistent conclusion. Some authors have reported that soil texture has a more significant influence on the AMF community than soil chemical properties (Da Silva et al 2015, Duarte et al 2019. However, other studies have found that while soil chemistry does modify the AMF community, soil texture does not appear to do so (Pagano et al 2013).…”

Biogeosciences and Forestry Biogeosciences and Forestry Shifts in the arbuscular mycorrhizal fungal community composition of Betula alnoides along young, middle-aged plantation and adjacent natural forest Yuebo Jing (1-2) , Tao Li (1) , Hongliang Cui (3) , Lingfei Li (4) , Samuel C Allen (5) , Lin Chen (1) , Yongpeng Li (2) , Zhiwei Zhao (1) Betula alnoides is a fast-growing and native timber species prevalently planted in tropical and subtropical areas of southern China. Despite the large-scale development of B. alnoides plantations, knowledge of its association with arbuscular mycorrhizal fungi (AMF) is limited. In the present study, we chose young (3-year-old sapling, P3y) and middle-aged (12-year-old stand, P12y) B. alnoides plantations and adjacent native forest (N) in the Puwen Tropical Forest Experimental Station located in Xishuangbanna prefecture of Yunnan Province, southwestern China, as study materials and explored the change in AMF community composition in the plantation chronosequence. In addition, we combined morphological methods and Illumina MiSeq sequencing techniques to analyze rhizosphere soil AMF. The results indicated that the AMF richness and diversity indexes of B. alnoides at two ages tended to be similar to those of natural growing trees in native forest. However, the specific AM fungal compositions were distinctly different, providing evidence of the conservation value of the native forest, which harbors a unique AMF diversity. Hierarchical cluster analysis further revealed that the AMF community composition of trees in the mid-aged stand (P12y) was more similar to that of naturally growing B. alnoides (N) than that of the young-aged trees (P3y), which proved the considerable resilience of AMF to the establishment of the B. alnoides plantation. A set of at least five soil properties (available phosphorus, available nitrogen, organic matter, total nitrogen and silt content) was found to play a significant role in shaping the AMF communities. These results contribute to the understanding of the impacts of B. alnoides plantations on AMF diversity and composition. Such information is critical for the efficient planting and sustainable management of B. alnoides plantations.

“…To ascertain the discrepancies in AMF communities among these forests, the researchers evaluated spore abundance, diversity indices, and root colonization rates. The study findings showed that spore abundance was at its minimum in LLF and maximum in REF, with no significant variations compared to MTF [31]. This indicates that the abundance of AMF spores is shaped by the particular traits of individual forest types (Table 1).…”

The ever-increasing change in land utilization has been acknowledged as a primary factor influencing ecological modifications. These alterations have reignited the interest in understanding the enduring consequences on different soil microorganisms, specifically arbuscular mycorrhizal fungi (AMF). This study investigates the effects of land-use changes (LUCs) on AMF diversity, highlighting the impact of forest degradation, intensified farming approaches, and urban growth on the structure of the AMF community and its mediated services. Research has found that deforestation leads to a decrease in AMF diversity, thereby intensifying the susceptibility of particular species to habitat degradation. The transformation of natural habitats into cultivated landscapes due to agricultural spiraling driven by the need for food production also impacts the diversity of AMF. Urbanization, an expeditiously advancing modification of land usage, has been found to have the potential to cause the fragmentation and degradation of habitats, thus impacting ecosystem benefits of AMF, such as nutrient cycling and water filtration. These changes can have far-reaching consequences for plant communities, nutrient cycling, and ecosystem functioning. Future research should prioritize the development of management strategies, investigating AMF-mediated ecosystem services, and comprehending fundamental mechanisms governing AMF responses to land-use change. This knowledge can guide sustainable land management practices emphasizing AMF diversity and function conservation.

“…Arbuscular mycorrhizal fungi have also shown differences in colonization rates among the same host plants across a gradient from coastal to inland habitats (Guillén et al, 2019). However, Duarte et al (2019) saw no significant difference in PRLC in similar plant communities among three distinct forest types—from lowland to montane. Combined with our results, these studies suggest that PRLC can be affected by various factors including climate, edaphic conditions, and habitat type.…”

Premise Prior efforts have shown that continents harbor a greater proportion of mycorrhizal hosts than on islands. However, in the Hawaiian Islands, estimates of the proportion of mycorrhizal plant species are higher than on continents (>90%), but there are few studies to support this claim. Concurrently, Hawaii's flora faces some of the greatest global risks of extinction, and significant efforts are aimed at restoring native vegetation. Arbuscular mycorrhizal (AM) fungi have been shown to improve plant restoration success, but little work has been done in Hawaii to understand the extent of mycorrhizal associations among native plant populations. Methods We surveyed 35 native Hawaiian plant species in the wild, focusing on plant species that are reared for reintroduction. Roots from wild individuals were collected from 10 sites on Oahu to determine degree of mycorrhizal fungal colonization and how this varies across host populations. Results Of the species surveyed, 97% had evidence of mycorrhizal colonization, including 25 endemic and nine indigenous species from 23 families. The mycorrhizal status of 22 of the species surveyed was unknown before this study. For four species, the degree of colonization by AM fungi differed among sites, and these differences corresponded with variations in precipitation and temperature. Conclusions The high incidence of mycorrhizal colonization provides evidence that island flora can actually harbor more mycorrhizal hosts than species on mainlands and that future reintroduction projects should consider the potentially important roles of AM fungi for success of these hosts in the wild.
