Soil enzymes in response to climate warming: Mechanisms and feedbacks

Functional Ecology, Journal Year: 2022, Volume and Issue: 36(6), P. 1378 - 1395

Abstract Soil enzymes are central to ecosystem processes because they mediate numerous reactions that essential in biogeochemical cycles. However, how soil enzyme activities will respond global warming is uncertain. We reviewed the literature on mechanisms linking temperature effects and microbial communities, outlined a conceptual overview these changes may influence carbon fluxes terrestrial ecosystems. At scale, although can have positive effect enzymatic catalytic power short term (i.e. via instantaneous response of activity), this be countered over time by inactivation reduced substrate affinity. short‐term increase accelerated synthesis turnover, but shifts community composition growth efficiency long term. Although increasing accelerate labile decomposition months years, our review highlights initial stage followed following phases: (a) reduction loss, due changing use among communities or depletion, which together decrease biomass activity (b) an acceleration structure greater allocation oxidative for recalcitrant degradation.

Positive associations fuel soil biodiversity and ecological networks worldwide

Proceedings of the National Academy of Sciences, Journal Year: 2024, Volume and Issue: 121(6)

Published: Jan. 29, 2024

Microbial interactions are key to maintaining soil biodiversity. However, whether negative or positive associations govern the microbial system at a global scale remains virtually unknown, limiting our understanding of how microbes interact support biodiversity and functions. Here, we explored ecological networks among multitrophic organisms involving bacteria, protists, fungi, invertebrates in survey across 20 regions planet found that both pairs triads taxa governed networks. We further revealed with greater levels supported larger resulted lower network fragility withstand potential perturbations species losses. Our study provides unique evidence widespread between their crucial role structure worldwide.

Linking phylogenetic niche conservatism to soil archaeal biogeography, community assembly and species coexistence

Global Ecology and Biogeography, Journal Year: 2021, Volume and Issue: 30(7), P. 1488 - 1501

Published: May 19, 2021

Abstract Aim A predictive understanding of the mechanisms underlying microbial biogeographical patterns is great interest, particularly with respect to phylogenetic distributions their ecological adaptations. Here, we test whether information can predict distributions, community assembly and species co‐occurrence soil archaea. Location Northern China. Time period July August 2017. Major taxa studied Archaeal communities. Methods By conducting a large‐scale (transect intervals 1,257.6 km) study across agricultural field, forest, wetland, grassland desert biomes, applied framework niche conservatism investigate archaeal biogeography, network topology. We examined signal based on Blomberg's K environmental preference given taxon was related phylogeny, corresponding degree for niches complex gradients. evaluated processes communities null model Sloan neutral analyses. then explored major factors that influenced coexistence Results Soil exhibited strong climate‐related preferences. Mean annual precipitation (MAP) had strongest signal, this mediated both coexistence, stronger deterministic less in environments lower precipitation. Phylogenetic diversity closely linked balance processes; is, stochastic were dominant low‐diversity communities, whereas variable selection promoted high diversity. Main conclusions conclude archaea drives distributions. Our findings represent considerable advance linking therefore forecasting evolutionary adaptations response ongoing changes.

Abundant fungal and rare bacterial taxa jointly reveal soil nutrient cycling and multifunctionality in uneven-aged mixed plantations

Ecological Indicators, Journal Year: 2021, Volume and Issue: 129, P. 107932 - 107932

Published: June 28, 2021

Uneven-aged silvicultural practices can maintain habitat continuity and enhance biodiversity. Soil microorganisms play critical roles in multiple ecosystem functions (i.e., multifunctionality). However, little is currently known regarding the role of microbial community driving soil nutrient cycling multifunctionality (SMF) uneven-aged mixed plantations. In this study, we investigated bacterial fungal compositions diversities, single-function related carbon (C), nitrogen (N), phosphorus (P) cycling, SMF indices monoculture plantation (as a control) three stands (4, 7, 11 years old). Our results demonstrated that C, N, P plantations increased by 17.9–55.2%, 20.0–54.0%, 0.7–21.6%, 16.3–30.1% compared to plantation. The alpha diversity (richness Shannon diversity), significantly improved with stand age, but showed less variation. beta diversities bacteria fungi notable variation age were predominantly affected properties (soil organic total P, C/N ratio), respectively. Additionally, temporal turnover within was higher than rates community. biomass more sensitive structure change over short period (11 years) biomass. Furthermore, fungi/bacteria (F/B) ratio strongly positively correlated SMF. Most importantly, abundant taxa (e.g., Mucoromycota Mortierellomycota) major drivers SMF, followed rare Nitrospirae Elusimicrobia). These findings indicate communities have different responses undertake important maintaining when converted into an
