Abstract Different fungal guilds within the soil community regulate forest ecosystem processes. Soil fungi are dictated by edaphic factors such as water and nutrient availabilities. However, how total number of composition different in vary under covarying pattern nitrogen deposition precipitation regime temperate forests has not been well documented. In this study, we explored effects long‐term nitrogen‐water interactions on diversity overall guilds, their relationships with fine‐root mycelial traits a forest. The totality or any did change, but saprotrophic symbiotrophic was significantly changed addition (N), showing increased abundance decreased fungi. Precipitation reduction (W) altered pathotrophic community. combined (WN) overall, composition. pathotrophic, variously related to diameter, root tissue density, and/or phosphorus concentration. Long‐term complexity networks, reflected lower edges average degree, higher path distance modularity. These findings guild‐specific responses will deepen our understanding carbon sequestration potential cycling ecosystems future climate changes.

Our understanding of the fundamental role that soil bacteria play in structure and functioning Earth's ecosystems is ever expanding, but insight into nature interactions within these bacterial communities remains rudimentary. Bacterial facilitation may enhance establishment, growth, succession eukaryotic biota, elevating complexity diversity entire community thereby modulating multiple ecosystem functions. Global climate change often alters composition, which, turn, impacts other dependent biota. However, impact on poorly understood even though it have important cascading consequences for ecosystems. The wealth metagenomic data currently being generated gives ecologists ability to investigate natural world how affects ecological systems responses change. Here, we review current evidence demonstrating importance promoting emergent properties such as diversity, functioning, resilience communities. We show a synthesis missing between abundant data, newly developed models coherent framework addresses properties. highlight including phylogenetic information, physicochemical environment, species‐specific ecologies can improve our infer Following recommendations, studies will be an piece puzzle understand global model advance complex more generally.

Increased atmospheric nitrogen (N) deposition alters the structure and function of soil microbial communities in terrestrial ecosystems, consequently exerting a profound influence on ecosystem processes. However, effects N network complexity its regulation carbon (C) processes semiarid grassland ecosystems are poorly understood. In this study, based 13-year multilevel field addition experiment Loess Plateau, together with metagenomic sequencing molecular ecological analysis methods, we found that both topsoil subsoil exhibited hump-shaped response to addition, thresholds between 4.60 g m−2 yr−1 9.20 yr−1. Structural equation model (SEM) revealed major determinants shifted from physicochemical properties bacterial community composition along gradient. Further N-induced alterations could modulate C by affecting functional structures communities. For instance, complexity, abundance genes involved starch hemicellulose degradation, use efficiency decreased significantly under high levels addition. These results provide empirical evidence for close linkages highlight need disentangle mechanisms underlying nonlinear interactions improve projections.
