Abstract Cross‐kingdom associations play a fundamental role in ecological processes. Yet our understanding of plant–fungal co‐occurrences tropical rainforests and the potential impacts land‐use change shaping species connections remain limited. By using amplicon sequencing on DNA from roots their associated fungal communities, we aim to understand impact rainforest transformation composition structure root–fungal networks human‐modified landscapes Sumatra, Indonesia. Each type supports distinctive set indicator species, which are organisms that reflect specific environmental conditions can signal changes ecosystem health. We observed decline richness plant taxa with increasing intensification. Additionally, there is turnover root shifting native endemic non‐native, generalist herbaceous rubber oil palm plantations. Plant–fungal connectivity significantly declined intensification, suggesting managed ecosystems may have weakened root‐fungal interactions. Network analysis highlights distinct responses various groups. For instance, arbuscular mycorrhizal fungi (AMF) showed fewer modules linked roots, indicating monocultures. This aligns reduction AMF diversity converted areas compared forests, further reinforcing negative practices monocultures diversity. Synthesis .

Understanding intricate interplay between plants face provide valuable information for conservation efforts, agricultural practices, management strategies aimed at promoting biodiversity, soil health resilience context changing conditions. Moreover, it underscores importance communities' planning decisions support terrestrial ecosystems.

Root-associated fungal diversity in Central Africa’s most logged timber species (Aucoumea klaineana Pierre) suggests monodominance is independent of mycorrhizal associations

Aucoumea klaineana is the most important timber species in Central Africa, forming monodominant stands. While soil fungi are crucial for plant growth, their role promoting monodominance and supporting suppressed, light-demanding trees remains underexplored. This study, first to analyze root mycobiota of A. klaineana, investigates fungal communities stands old-growth mixed forests Gabon, plantations DRC using ITS2 rDNA SSU rRNA high-throughput sequencing. We identified high diversity both regions but found no "core mycobiota" across stand types or tree social status. Fungal varied significantly between types, emphasizing a context-dependent nature. Monodominance was not linked ectomycorrhizal (EcM), as EcM OTUs were arbuscular mycorrhizal (AM) exhibited richness, abundance low, possibly due scarcity arbuscules. No distinct suppressed trees. These findings challenge assumed link associations suggesting alternative mechanisms, such grafting, may influence dynamics. study provides foundation future research on belowground strategies that contribute persistence sustainable management klaineana.

A Quaternary Sedimentary Ancient DNA (sedaDNA) Record of Fungal–Terrestrial Ecosystem Dynamics in a Tropical Biodiversity Hotspot (Lake Towuti, Sulawesi, Indonesia)

Short-term observations suggest that environmental changes affect the diversity and composition of soil fungi, significantly influencing forest resilience, plant diversity, processes. However, time-series experiments should be supplemented with geobiological archives to capture long-term effects on fungi–soil–plant interactions, particularly in undersampled, floristically diverse tropical forests. We recently conducted trnL-P6 amplicon sequencing generate a sedimentary ancient DNA (sedaDNA) record regional catchment vegetation waterbody Lake Towuti (Sulawesi, Indonesia), spanning over one million years (Myr) lake’s developmental history. In this study, we performed 18SV9 create parallel paleofungal (a) infer composition, origins, functional guilds community members (b) determine extent which downcore fungal reflect late Pleistocene evolution catchment. identified at least 52 Ascomycota (predominantly Dothiodeomycetes, Eurotiomycetes, Leotiomycetes) 12 Basidiomycota (primarily Agaricales Polyporales).

Soil fungi lead to stronger ‘diminishing returns’ in fine‐root length versus mass allometry towards earlier successional tropical forests

Abstract Decreasing returns in resource acquisition ability with increasing leaf mass investment is called ‘diminishing returns’, which provides important insights into plant economy. Yet, whether this true for fine roots and how root strategies change forest succession remain unclear. We investigated the scaling relationship between fine‐root length ( L ) M 215 topsoil cores from 24 plots across four successional stages tropical forests of Xishuangbanna, southwestern China. also assessed relative effects edaphic conditions, functional traits, tree species diversity soil fungal factors on versus using hierarchical variation partitioning.

Assemblies of leaf and root mycobiomes in a temperate grassland: Dispersal limitation overpowers selection

Abstract The emergence of β‐diversity plant‐associated fungi across diverse coexisting host plant species in natural habitats is intricately linked to specific community assembly processes. Despite this, the relative contributions various processes observed patterns, as well influence traits on these contributions, are still poorly understood. Here, we investigated leaf/root‐associated fungal communities nine dominant herbaceous perennials a temperate grassland that had undergone 17‐year mowing treatment. We elucidated components and communities. Furthermore, explored relationships between leaf/root functional trait variations assemblies. tested following hypotheses: (1) both turnover nestedness important β‐diversity, with selection predominating assemblies; (2) enhances nestedness/selection; (3) significantly affect Unexpectedly, our findings demonstrated predominance among hosts, contrasting nestedness. Moreover, dispersal limitation emerged primary factor shaping assemblies, rather than Although inhibited growth, its effects overall patterns assemblages were limited. further higher degrees primarily stronger limitation, relatively weaker heterogeneous selection. Additionally, impact process root‐associated was more pronounced compared leaf‐associated fungi. Synthesis . Our study reveals associated plants grasslands attributed replacement gain‐and‐loss dynamics plants. Concurrently, this pattern largely governed by opposed propose mechanism through which hosts their structures limiting dispersal, while niche differentiation taxa plays secondary role. These offer mechanistic insight into assemblies mycobiomes elucidate plant‐mycobiome within complex
