Warming can alter above\uffe2\uff80\uff90 and belowground linkages that regulate soil organic carbon dynamics and C\uffe2\uff80\uff90balance in peatlands. Here we examine the multiyear impact of in situ experimental warming on the microbial food web, vegetation, and their feedbacks with soil chemistry. We provide evidence of both positive and negative impacts of warming on specific microbial functional groups, leading to destabilization of the microbial food web. We observed a strong reduction (70%) in the biomass of top\uffe2\uff80\uff90predators (testate amoebae) in warmed plots. Such a loss caused a shortening of microbial food chains, which in turn stimulated microbial activity, leading to slight increases in levels of nutrients and labile C in water. We further show that warming altered the regulatory role of Sphagnum\uffe2\uff80\uff90polyphenols on microbial community structure with a potential inhibition of top predators. In addition, warming caused a decrease in Sphagnum cover and an increase in vascular plant cover. Using structural equation modelling, we show that changes in the microbial food web affected the relationships between plants, soil water chemistry, and microbial communities. These results suggest that warming will destabilize C and nutrient recycling of peatlands via changes in above\uffe2\uff80\uff90 and belowground linkages, and therefore, the microbial food web associated with mosses will feedback positively to global warming by destabilizing the carbon cycle. This study confirms that microbial food webs thus constitute a key element in the functioning of peatland ecosystems. Their study can help understand how mosses, as ecosystem engineers, tightly regulate biogeochemical cycling and climate feedback in peatlands</p>", "keywords": ["0106 biological sciences", "2.

We collected water samples for measuring water chemistry, and we determined landscape parameters using GIS based tools. The data was collected at three sampling periods in summer 2021 in the Zackenberg Research Station (74\u00b028'N, 20\u00b034'W). The area has a polar tundra climate with mean annual air temperature of -9.1 \u00b0C. Water chemistry (i.e. dissolved and particulate nitrogen, phosphorus, carbon; dissolved iron and silicate) and catchment characteristics (i.e. catchment area, altitude, slope, aspect, NDVI, snow cover) was measured for each of the 14 stream sites. Water chemistry samples were collected and analyzed using standard methods, and landscape characteristics were determined using GIS resources. The data was collected in order to study relationships between landscape characteristics and stream water chemistry. The water samples were collected by a team of two people, and the detailed methods are given below.", "keywords": ["inorganic", "median", "Nitrate Nitrogen", "Nitrogen", " inorganic", " dissolved/Nitrogen", " total dissolved ratio", "Nitrate", "Normalized Difference Vegetation Index", "Latitude of event", "Inductively Coupled Plasma Mass Spectrometry ICP MS", "Arctic", "Temperature", " water", "WTW", "Total organic carbon analyzer TOC VCPH TNM 1", "Total organic carbon analyzer (TOC-VCPH/TNM-1)", " Shimadzu", "Calculated", "dissolved ratio", "Nitrate/Nitrogen", " inorganic", " dissolved ratio", "total dissolved ratio", "Multiple investigations", "Temperature", "Nitrogen", " total dissolved", "Month", "dissolved", "specific", "streams", "6.
