Interplay of biotic and abiotic factors shapes tree seedling growth and root-associated microbial communities

Communications Biology, Год журнала: 2024, Номер 7(1)

Опубликована: Март 22, 2024

Abstract Root-associated microbes can alleviate plant abiotic stresses, thus potentially supporting adaptation to a changing climate or novel environments during range expansion. While change is extending species fundamental niches northward, the distribution and colonization of mutualists (e.g., arbuscular mycorrhizal fungi) pathogens may constrain growth regeneration. Yet, degree which biotic factors impact performance associated microbial communities at edge their remains unclear. Here, we use root microscopy, coupled with amplicon sequencing, study bacterial, fungal, root-associated from sugar maple seedlings distributed across two temperate-to-boreal elevational gradients in southern Québec, Canada. Our findings demonstrate that soil pH, Ca, distance trees are key drivers communities, overshadowing influence elevation. Interestingly, changes fungal community composition mediate an indirect effect pH on seedling growth, pattern consistent both sites. Overall, our highlight complex role shaping tree-microbe interactions, turn correlated growth. These have important ramifications for tree expansion response shifting climatic niches.

Limiting Resources Define the Global Pattern of Soil Microbial Carbon Use Efficiency

Advanced Science, Год журнала: 2024, Номер unknown

Abstract Microbial carbon (C) use efficiency (CUE) delineates the proportion of organic C used by microorganisms for anabolism and ultimately influences amount sequestered in soils. However, key factors controlling CUE remain enigmatic, leading to considerable uncertainty understanding soil retention predicting its responses global change factors. Here, we investigate patterns estimate stoichiometric modeling surface soils natural ecosystems, examine associations with temperature, precipitation, plant‐derived nutrient availability. We found that is determined most limiting resource among these four basic environmental resources within specific climate zones (i.e., tropical, temperate, arid, cold zones). Higher common arid corresponds limitations water, input, while lower observed tropical temperate widespread limitation nutrients (e.g., nitrogen or phosphorus) soil. The contrasting led an apparent increase increasing latitude. resource‐specific dependence implies high latitudes environments may retain less future, as warming increased precipitation can reduce CUE. In contrast, oligotrophic low retention, could be concurrent anthropogenic inputs. findings underscore importance suggest asymmetric across

Differential roles of deterministic and stochastic processes in structuring soil bacterial ecotypes across terrestrial ecosystems

Nature Communications, Год журнала: 2025, Номер 16(1)

Опубликована: Март 8, 2025

Soil bacteria are vital to ecosystem resilience and resistance, yet ecological attributes the drivers governing their composition distribution, especially for taxa varying in traits inhabiting different ecosystems, not fully understood. Here, we analyzed a large-scale bacterial community environmental dataset of 622 soil samples systematically collected by us from six major terrestrial ecosystems across United States. We show that diversity significantly differ among ecotypes partially determined few universal abiotic factors (e.g., pH, calcium, aluminum) several ecotype- or ecosystem-specific drivers. Co-occurrence network analysis suggests rare have stronger relevance than abundant taxa. Ecological models revealed deterministic processes shape assembly generalists, while stochastic played greater role specialists. Also, communities shrubland appear be more sensitive changes other evidenced lowest diversity, least connected network, strongest local selection driven surrounding land use. Overall, this study reveals mechanisms underlying biogeography nationwide highlights need preserve biosphere amid disturbance. Determinants microbial structure less well studied. Riddley et al. profile biogeographic patterns, identify key distinct roles shaping ecotype ecosystems.

Heavy metals are commonly present in polluted soil mining areas. In this study, we investigated 10 sites of farmland the heavy metal tailing dam collapse area (TDCA) with dominant phyla Acidobacteriota, Proteobacteria, Bacteroidetes, and Planctomycetes. The is a composite contamination multiple metals, Cd, Pb Zn being most severely contaminated, levels Hg Cu exceeding screening values at some sites. Shannon, Chao1 ACE indices revealed high microbial diversity but low relative abundance microorganisms TDCA1 TDCA3 results redundancy analysis (RDA) showed that (Max = 4.31 mg/kg) 100 were important factors affecting community TDCA compared to other metals. Correlation communities RB41 (Acidobacteria) was more resistant concentrations Pb, pollution. genera UTCFX1 (Chloroflxi) norank_TRA3-20 had strong tolerance Hg. significantly negatively correlated norank_WD2101_soil_group (P < 0.05). Therefore these can be used as indicators for monitoring potential contamination. predict changes ecosystem maintain its ecological balance health.
