Extreme climatic events, such as drought, can significantly alter belowground microbial diversity and species interactions, leading to unknown consequences for ecosystem functioning. Here, we simulated a drought gradient by removing 30 %, 50 %, and 70 % of precipitation in a semi-arid grassland over five years. We assessed the effects of drought on bacterial and fungal diversity, as well as on their species interactions.

Climate change affects groundwater availability and residence times, necessitating a thorough understanding of aquifer characteristics to define sustainable yields, particularly in regions where water is heavily exploited. This study focuses on the Volvic volcanic aquifer (Chaîne des Puys, France), where groundwater recharge has decreased due to climate change, raising concerns about water use sustainability. To address these challenges, this work proposes a multi-tracer approach, based on hydrogeological monitoring, including the estimation of groundwater ages, major elements chemistry and water stable isotopes to better characterise this resource decrease and more peculiarly its origin and its impact on the environment that has never been addressed.

The continuous progression of industrialisation and the burgeoning global population have precipitated the non-renewable energy crisis and exacerbated environmental problems, thereby stimulating a huge demand for production of environmentally friendly materials. Typically, biomass-based aerogels (BAs) derived from cellulose, chitosan (CS), lignin, and alginate have been gradually captivating the attention of researchers owing to their high specific surface area, substantial porosity, low density, porous architecture, and biodegradability. In this review, we demonstrate the sustainability of BAs by contrasting the overall advantages or disadvantages of BAs with those of synthetic alternatives in terms of cost, insulation performance, and planetary boundaries.

Climate change is expected to lead to an increase in precipitation and flooding. Consequently, plants that are adapted to dry conditions have to adjust to frequent flooding periods. In this study, we investigate the flooding response of , a Mediterranean plant adapted to warm and dry conditions.

Soil fungi are essential to ecosystem processes, yet their elevational distribution patterns and the ecological mechanisms shaping their communities remain poorly understood and actively debated, particularly in arid regions. Here, we investigated the diversity patterns and underlying mechanisms shaping soil fungal communities along an elevational gradient (1,707-3,548 m) on the northern slope of the Central Kunlun Mountains in northwest China. Results indicated that the dominant phyla identified across the seven elevational gradients were and , displaying a unimodal pattern and a U-shaped pattern in relative abundance, respectively.
