Rising temperatures are influencing forests on many scales, with potentially strong variation vertically across forest strata. Using published research and new analyses, we evaluate how microclimate leaf temperatures, traits, gas exchange vary in forests, shaping tree, ecosystem ecology. In closed-canopy upper canopy leaves exposed to the highest solar radiation evaporative demand, which can elevate temperature (Tleaf ), particularly when transpirational cooling is curtailed by limited stomatal conductance. However, foliar traits also height or light gradients, partially mitigating protecting against elevation of Tleaf . Leaf metabolism generally increases vertical gradient, yet differences thermal sensitivity gradient appear modest. Scaling from trees, trees have higher absolute metabolic capacity growth, more vulnerable drought damaging than their smaller counterparts, under climate change. By contrast, understory experience fewer extreme high 's but mechanisms thus may be strongly impacted warming some conditions, a harsher microenvironment through disturbance. As changes, integrating patterns reviewed here into models will critical forecasting forest-climate feedback.

Abstract Via sheltering, decoupling and buffering mechanisms, tree canopies have the capacity to mitigate impacts of multiple global‐change drivers on below‐canopy processes organisms in forests. As a result, an important potential as nature‐based solution. The optimal combinations forest canopy structural attributes jointly received little attention date. To help solving this research gap, here we review how modulate effects four drivers—climate warming, drought, air pollution biological invasions—on conditions. Particular is paid mitigating that can be influenced by management, including cover, species composition vertical horizontal structure. Synthesis . We show highly context‐dependent canopy‐based solutions strongly depend environmental context targeted subcanopy organisms. Hence, holistic approaches, which maximize synergies minimize trade‐offs, are needed optimize solution canopies.

Forest canopies buffer the macroclimate and thus play an important role in mitigating climate-warming impacts on forest ecosystems. Despite importance of tree layer for understory microclimate buffering, our knowledge about effects structure, composition their interactions with is limited, especially mixtures conifers broadleaves. Here we studied five mixed stands along a 1800 km latitudinal gradient covering 7°C span mean annual temperature. In each these forests established 40 plots (200 total), which air soil temperatures were measured continuously at least one year. The located across gradients density broadleaved proportions (i.e. from open to closed canopies, 100% conifer dominance).

Coppicing is one of the oldest silvicultural practices and still widely applied to produce renewable energy from broadleaf forests. However, consequences on microclimate understorey vegetation are poorly understood, especially in Mediterranean oak With ongoing changes climate system global biodiversity loss, a better understanding how forest temperature buffering capacity below-canopy plant community impacted by coppicing crucial. Here we quantify adjacent ancient coppice-with-standards high stands dominated oaks Italy, where these systems have been for long time. Air soil temperatures were recorded 2.5 years, nested plots used analyse effects species composition, taxonomic, phylogenetic, functional diversity. significantly reduced capacity. The mean daily maximum over entire period was 1.45 °C higher coppiced sites, whereas minimum 0.62 lower than forest. increased richness favouring generalist taxa, but decreased proportion specialists. forests consisted more warm-adapted species.

Abstract Questions Forests are highly fragmented across the globe. For urban forests in particular, fragmentation increases exposure to local warming caused by heat island (UHI) effect. We here aim quantify edge effects on herbaceous understorey vegetation forests, and test whether these interact with forest structural complexity. Location set up a pan‐European study at continental scale including six Zurich, Paris, Katowice, Brussels, Bremen, Stockholm. Methods recorded plant communities from towards interior of forests. Within each forest, we studied edge‐to‐interior gradients paired stands differing Community composition was analysed based species specialism, life form, light, nutrient, acidity disturbance indicator values species' thermal niches. Results found that edges supported more generalists forbs but fewer ferns than forests' interiors. A buffered summer microclimate proved crucial for presence fern species. The contained thermophilous, disturbance‐tolerant, nutrient‐demanding basiphilous species, pattern strongly confirmed corresponding microclimate, soil light conditions understorey. Additionally, plots lower canopy cover higher availability numbers both specialists. Even though no significant interactions were between distance complexity, opposing additive indicated dense can be used buffer negative effects. Conclusion environment poses multifaceted filter which contributes differences community biodiversity conservation buffering effects, it will key maintain canopies near edges.
