Background and aims Urbanization is a stressor that can exacerbate climate change impacts. Urban ecosystems are hotter and drier than their rural counterparts, due to a lack of vegetation and an abundance of impermeable surfaces that characterize cities. Urban greening projects can reverse these trends through microclimate cooling and humidification. Vegetation and aridity gradients have the capacity to modify how neighboring plants interact with one another: plant neighbors may benefit one another through facilitation in hot and dry environments but experience more competition in cooler and more humid areas. We examined how herbaceous plants can ameliorate heat and water stress across an established urban aridity gradient in the greater Los Angeles area. Methods We measured 162 plants at 81 plots in 27 sites across a well-established urban-to-rural gradient. In each plot, we identified two pre-existing focal individuals: we removed the neighboring plants for one of these, and left the community intact around the other. We then measured growth of the two focal plants and placed temperature and humidity sensors near each. We also measured light above and below the canopy and total precipitation. Results We found that across the urban aridity gradient, the hottest sites experienced the most vegetative microclimate amelioration. We also found that neighboring plants had positive effects on growth (facilitation), but only when neighbors also cooled microclimate temperature and decreased microclimate vapor pressure deficit (VPD). Facilitation between neighbors was also greatest at the sites with the least precipitation. Conclusion Previous studies have shown that plants may compete for limited resources but we show that interactions can shift to be more facilitative along an urban aridity gradient. Future work should use this information to augment restoration plans in urban environments.

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.
