摘要

土壤微生物群落提供了许多生态系统功能,如养分循环、分解和碳储存。然而,全球变化,包括土地利用和气候变化,影响土壤微生物群落和活动。由于极端天气事件(如热浪)的强度和频率趋于增加,我们研究了热应激对土壤微生物群落活动(如呼吸)的影响,这些土壤微生物群落经历了四种不同的长期土地利用强度处理(从粗放草地和集约草地到有机农田和常规农田)和两种气候条件(环境气候和预测未来气候)。我们假设集约土地利用和未来气候条件都会减少土壤微生物呼吸(H1),而实验性热应激会增加微生物呼吸(H2)。然而,这种增加在具有长期高强度土地利用历史和未来气候条件的土壤中不太明显(H3),真菌与细菌比例较高的土壤对变暖的响应更温和(H4)。我们的研究表明,在高土地利用强度(即粗放型草地与常规农田之间- 43%)和未来气候条件(与环境气候相比- 12%)下,土壤微生物呼吸减少。此外,热应激增加了总体微生物呼吸(每增加1°C +17%),而增加土地利用强度降低了这一响应的强度(坡度减少- 25%)。此外,在低强度土地利用(即粗放型草地)条件下,土壤微生物生物量和真菌细菌比的增加增强了微生物呼吸对热胁迫的响应。这些发现表明,土地集约利用和气候变化可能会损害土壤微生物群落的活动及其在热浪下的呼吸作用。特别是,高强度土地利用和未来气候下的土壤微生物群落对额外压力(如热浪)的响应能力较弱,这可能威胁到土壤微生物驱动的关键生态系统功能,并突出了更可持续农业做法的好处。

Sustainable Land Use Enhances Soil Microbial Respiration Responses to Experimental Heat Stress

Soil microbial communities provide numerous ecosystem functions, such as nutrient cycling, decomposition, and carbon storage. However, global change, including land-use and climate changes, affects soil microbial communities and activity. As extreme weather events (e.g., heatwaves) tend to increase in magnitude and frequency, we investigated the effects of heat stress on the activity (e.g., respiration) of soil microbial communities that had experienced four different long-term land-use intensity treatments (ranging from extensive grassland and intensive grassland to organic and conventional croplands) and two climate conditions (ambient vs. predicted future climate). We hypothesized that both intensive land use and future climate conditions would reduce soil microbial respiration (H1) and that experimental heat stress would increase microbial respiration (H2). However, this increase would be less pronounced in soils with a long-term history of high-intensity land use and future climate conditions (H3), and soils with a higher fungal-to-bacterial ratio would show a more moderate response to warming (H4). Our study showed that soil microbial respiration was reduced under high land-use intensity (i.e., −43% between extensive grassland and conventional cropland) and future climate conditions (−12% in comparison to the ambient climate). Moreover, heat stress increased overall microbial respiration (+17% per 1°C increase), while increasing land-use intensity reduced the strength of this response (−25% slope reduction). In addition, increasing soil microbial biomass and fungal-to-bacterial ratio under low-intensity land use (i.e., extensive grassland) enhanced the microbial respiration response to heat stress. These findings show that intensive land use and climate change may compromise the activity of soil microbial communities as well as their respiration under heatwaves. In particular, soil microbial communities under high-intensity land use and future climate are less able to respond to additional stress, such as heatwaves, potentially threatening the critical ecosystem functions driven by soil microbes and highlighting the benefits of more sustainable agricultural practices.
