Summary: Peatlands and associated ecosystem services are vulnerable to climate change and human disturbances, as demonstrated in the study of Forbonnet bog. Restoration efforts, such as backfilling of artificial drains, have shown positive effects on water table depth and lateral inflows, highlighting the complex nested hydrological functioning of peatlands. This multi-reservoir model operates at varying spatio-temporal scales and will be increasingly impacted by climate change in the future.

Summary: Climate is a major driver of species distributions, but different species respond differently to climate change. This study focuses on the ability of limited dispersal and habitat-specialist species to track climate change at a local scale. The genetic and demographic impacts of past climate cycles are compared in three butterfly species in the Jura massif. The study finds similarities in thermal niche and population histories, but no correlation between changes in suitable areas and population size. This suggests that species ranges moved beyond the study area during unfavorable climatic periods, and habitat loss and deterioration are major drivers of the species' decline.

Summary: In this study, the peatland-vegetation model (LPJ-GUESS) was used to simulate peatland carbon dynamics under different future climate conditions. It was found that under less pronounced warming, peatlands may enhance their carbon sink capacity and buffer the effects of climate change. However, in a warmer world, higher respiration rates will dominate the carbon dynamics and reduce the carbon sink capacity.

Summary: Research on two developing peatlands in the Changbai Mountain region of northeastern China revealed that the plant community in these peatlands is mainly characterized by sedges and mosses during the entire plant succession process. The Yuan Lake peatland showed a wetter trend, favoring peat accumulation and development, while the Chi Lake peatland exhibited a steady peat decomposition and accumulation process. The presence of mosses had a clear impact on the variations in the C/N ratio.

Summary: Peatland pools are dynamic aquatic ecosystems that contribute to biogeochemical cycles, but their response to environmental change is poorly understood. This study analyzed pool biogeochemical data from multiple locations to determine the drivers of carbon, nitrogen, and phosphorus dynamics in peatland pools. Climate and terrain were found to explain variations in pool biogeochemistry, with climate driving spatial differences in dissolved organic carbon concentration. The study also demonstrated the reactivity of peatland pools to local and global environmental change. These findings highlight the importance of understanding and monitoring peatland pool dynamics as potential climate sentinels.

Summary: The research suggests a persistent regional climate pattern in which the drying of peatlands in northern Poland coincides with warming over long timescales. While there were simultaneous shifts in hydrological and temperature reconstructions on shorter timescales, the relationship between the two variables was surprisingly strong at centennial to millennial timescales, indicating that drought conditions change along with summer temperatures. Further peatland drying is expected in northern Poland if this millennial-scale pattern holds for the projected warming.

Summary: We conducted a 7-year fragmentation experiment in nutrient-poor grasslands in Switzerland to examine the effects of fragmentation on species richness, composition, abundance, genetic diversity, functional diversity, species traits, and interactions. Our findings showed that the responses to fragmentation varied among taxonomical groups and species, with some groups experiencing lower species richness and individual density in fragments while others showed the opposite trend. Fragmentation had the most pronounced effects on species interactions, with some effects occurring after a delay. For example, fragmentation influenced the foraging patterns of bumblebees, which in turn affected pollination and resulted in decreased genetic diversity in a focal plant species. Our study highlights the implications of these findings for grassland conservation.

Summary: This study provides a detailed assessment of weather types in New Zealand, showing that the precipitation and temperature anomalies associated with these types are more complex than previously thought. The analysis reveals that these anomalies are not solely determined by the occurrence of certain weather types, but are also influenced by changes in the location and intensity of atmospheric centers of action and their interaction with surface terrain. This understanding improves the accuracy of weather forecasting in the region.

Summary: Most water reservoirs are challenging to monitor as they are located underground, especially karst aquifers which have limited observations. In this study, a new approach using the Random Forests algorithm and seismic noise records is proposed to predict underground river water height. The algorithm successfully predicts water height by analyzing signal energy features, even for weak noise recorded at the surface. The efficiency of the algorithm is above 95% for underground seismic stations and 53% for surface seismic stations, as measured by the Nash-Sutcliffe criterion.

Summary: This paper examines the optimal subsidy for organic conversion given by regulators to farmers facing adverse selection. It takes into account farmers' private information about their intrinsic motivation for organic farming. The study finds that the optimal subsidy remains constant within the range of farmers' revenue. As the profit gap between organic and traditional farming narrows, the optimal subsidy should decrease. While promoting organic farming to enhance societal acceptability positively impacts the proportion of land conversion, the promotion of both organic farming among farmers and the demand for organic products may have ambiguous effects leading to a decrease in the number of conversions.

Summary: Soil microbial communities play a crucial role in ecosystem processes and services, especially through their food webs. However, the impact of food web structure on ecosystem functioning is not well understood. In this study, the relationships between different aspects of microbial food web structure and ecosystem functions were investigated in a peatland. The results showed that trophic interactions and increasing connectance, biomass, and energy fluxes played a significant role in enhancing ecosystem functions. These findings highlight the importance of considering food web structure and energy flows in understanding biodiversity-ecosystem functioning relationships.

Summary: Future changes in Sahel precipitation are uncertain due to differences in projections from different climate models. This study identifies the driving factors behind these uncertainties and constructs possible scenarios based on changes in North Atlantic and Euro-Mediterranean temperatures. The results show that the uncertainties in Sahel precipitation can be attributed to the future warming of these regions. It is crucial to constrain the uncertainty in the warming of the North Atlantic and Euro-Mediterranean areas in order to reduce the uncertainty in Sahel precipitation.

Summary: This study examines the impact of topography and land cover on the spatial and temporal variability of air temperature in an urban environment. Through simple and multiple linear regression models, the study finds that topography and land cover have complementary influences on air temperature, with the largest impact during daytime and nighttime respectively. The multiple linear regression models significantly improve upon the simple linear regression models. Topography influences air temperatures throughout the year, with temperature decreasing with height during the day and frequent thermal inversions at night. Impervious surfaces have a greater influence in summer and early fall, while vegetation helps to cool air temperature at night.
