Background and Aims Wildfires in high-altitude dry shrublands of the Peruvian Andes are increasingly becoming a significant ecological threat, with substantial and potentially persistent impacts on soils. This study investigated how fire affects soil microbial communities and functions beneath two dominant shrub species, Berberis lutea and Parastrephia quadrangularis , which differ in biomass and fuel structure and therefore in the intensity of combustion that their soils are exposed to. We hypothesized that fire would modify microbial community composition, biomass and functional activity, leading to distinct recovery trajectories beneath the two shrub species due to their contrasting fuel characteristics. Methods We conducted a medium-term assessment (3–4 years post-fire) of soil microbial structure and activity using phospholipid fatty acids (PLFA), microbial respiration, microbial biomass carbon and enzyme activities. Results Fire effects on soils were species-specific. Soils beneath P. quadrangularis showed greater potential for bacterial and fungal communities recovery, while those under B. lutea soils were more severely affected, likely due to higher aboveground biomass. Despite these differences, both species experienced a strong and persistent reduction in enzymatic activities, indicating long-lasting impacts on soil functionality. In addition, soil properties such as aggregate stability and water repellency were identified as key factors associated with microbial recovery. Conclusions The results reveal the high vulnerability of Andean dryland soils to wildfire and highlight the role of vegetation type in determining post-fire microbial recovery. Incorporating soil biological indicators into post-fire restoration planning and soil vulnerability assessment may help reduce long-term degradation risks in these fragile high-altitude ecosystems.

Background and aims A major challenge in root exudation research is obtaining exudates samples that accurately reflect the exudation processes under natural soil growth conditions. Both growth environment and experimental setup can significantly influence root exudation dynamics. This study investigated how different experimental systems and growth conditions affect carbon exudation in maize ( Zea mays L.) roots and whether these factors could influence the detection of genotypic differences between the wild type (B73) and its hairless mutant, rth3. Methods Maize plants were grown under various experimental conditions, including soil-based and hydroponic systems. Root exudates were collected using a combination of traditional and innovative sampling approaches. Carbon exudation rates were compared across experimental setups and genotypes. Laboratory results were further compared with data from a separate field experiment. Results Exudation rates obtained from soil-based laboratory experiments were comparable to those observed in the field under similar growth temperatures. The contribution of root hairs to total carbon exudation was negligible compared to the effect of growth conditions and experimental setup. Large differences in root biomass introduced bias into exudation measurements, particularly when root to sampling volume ratio (RSVR) varied substantially. Conclusions Experimental setup and environmental conditions have a strong influence on root exudation measurement. Soil-based laboratory systems that closely replicate field conditions, particularly temperature, can serve as reliable proxies for field experiments, providing ecologically meaningful data. Maintaining a consistent RSVR is also essential for obtaining accurate and comparable results. These findings offer important methodological guidance for reliably quantifying root carbon exudation in maize
