Microrefugia, defined as small areas maintaining populations of species outside their range margins during environmental extremes, are increasingly recognized for role in conserving the face climate change. Understanding microclimatic dynamics becomes crucial with global warming leading to severe temperature and precipitation changes. This study investigates phenomenon short-term climatic decoupling within microrefugia its implications plant persistence Mediterranean region southeastern France. We focus on microrefugia's ability climatically disconnect from macroclimatic trends, examining Vapor Pressure Deficit (VPD) microrefugia, adjacent control plots, weather stations. Our encompasses both "normal" conditions heatwave episodes explore thermal moisture insulators extreme events. Landscape attributes such relative elevation, solar radiation, distance streams, vegetation height investigated contribution decoupling. results demonstrate that exhibit notable trends. effect is maintained heatwaves, underscoring vital responding extremes. Importantly, maintain lower VPD levels than surroundings potentially mitigating water stress plants. advances our understanding microclimate underscores ecological importance a changing climate. As heatwaves become more frequent severe, findings provide insights into buffering but also against events and, generally, warming. knowledge emphasizes need detect protect existing they can be integrated conservation strategies change adaptation plans.

HighlightsClimate-change refugia can support biodiversity by maintaining buffered conditions despite climate change and are a critical tool for the unfolding extinction crisis.Despite their capacity to protect biodiversity, climate-change will be increasingly vulnerable impacts of multiple interacting stressors may hence require management.Effective protection under facilitated managing or newly establishing on basis factors processes that create them.Using four clear steps, appropriate actions maintain refugia, ranging from minimal management more extensive restoration efforts, determined.Identifying reduce extinctions contribute landscapes holistically managed conservation change.AbstractEarth is facing simultaneous crises. Climate-change – areas relatively help address both these problems components when surrounding landscape no longer can. However, this often severe other stressors. Thus, need consider complex multidimensional nature refugia. We outline an approach understand refugia-promoting evaluate refugial determine suitable actions. Our framework applies as tools facilitate resistance in modern planning. Such refugia-focused change.

Cold-air pooling is an important topoclimatic process that creates temperature inversions with the coldest air at lowest elevations. Incomplete understanding of sub-canopy spatiotemporal cold-air dynamics and associated ecological impacts hinders predictions conservation actions related to climate change cold-dependent species functions. To determine if how influences forest composition, we characterized frequency, strength, temporal in local regional scales New England, USA. We established a network 48 plots along elevational transects continuously measured temperatures for 6-10 months (depending on site). then estimated overstory understory community preferences by surveying tree composition each plot combining these data known preferences. found was frequent (19-43% seasonal occurrences) sites most displayed inverted patterns across slopes more cold-adapted species, namely conifers, low instead high also observed both variability dynamics, revealing while common, it spatially complex. Our study, which uniquely focused broad spatial scales, has revealed some rarely reported dynamics. For instance, discovered strong occurred seasons locations were during daytime, likely affecting composition. Together, our results show fundamental requires integration into modeling efforts predicting future vegetation under change, as well greater consideration strategies identifying potential refugia species.

ABSTRACT Known as the largest negative terrain on earth's surface, karst tiankeng is isolated by vertical cliffs and maintains a unique ecosystem within it. However, knowledge of microbial ecology tiankengs does not match their importance. To this end, we conducted extensive sampling across 16 2 sites used high‐throughput sequencing methods to analyze soil bacteria fungi. This study found abundant diversified communities in tiankengs, with Proteobacteria , Acidobacteriota (Bacteria), Ascomycota Basidiomycota (Fungi) being main phyla. Compared degraded landscape, maintained higher richness bacterial taxa. The common exclusively taxa follow copiotrophic opportunistic strategies, these are associated high nutrients (TN SOM) water content. Karst stable network structure through cooperation, dispersal limitation dominated fungal community assembly. Our results enhance understanding microbiomes subterranean ecosystems, highlighting that important refuges for diversity landscapes.
