In the Mediterranean basin, urban forests are widely recognized as essential landscape components, playing a key role in nature-based solutions by enhancing environmental quality and providing range of ecosystem services. The selection woody plant species for afforestation reforestation should prioritize native that align with biogeographical ecological characteristics planting sites. Among these, Quercus cerris L. (Turkey oak) is considered promising candidate reforestation. However, its fitness within forest environments remains poorly understood. This study aimed to identify suitable leaf functional traits assessing response Q. analyze main climatic variables influencing performance contexts. We also proposed practical, rapid monitoring tools compare natural across different seasons. results demonstrated experiences significant water stress due combined effects drought high temperatures. To find mitigate this stress, differences between such specific area, thickness, contents chlorophyll, anthocyanins, flavonols were analyzed. Our findings underscore adaptability varied conditions. provides practical method rapidly responses tree climate change. future, approach will be tested on other characteristic ecosystems help choosing strategies.

Abstract The rapid growth of urban population has significantly changed human settlement patterns, leading to a decline in air quality and changes climatic conditions areas. Trees are recognized as nature-based solutions because they can remove particles from the regulate climate. However, trees negatively affected by pollution temperatures, which represent challenge for planning, management, health. To assess impact warmer climates on functional traits, we conducted study using Quercus humboldtii, an endangered tree species endemic Colombia Panamá that dominates Andean forests green areas Bogotá. We selected three localities with contrasting levels climate measured 10 morphological biochemical traits six individuals at each location. Our findings revealed Q. humboldtii adjusted response environmental challenges posed environments. strategies varied between thin large leaves acidic pH colder unpolluted native forest, while others displayed conservative resource strategy (high leaf dry matter content) neutral most polluted locality. Despite these differences, several indicate is not tolerant pollution. This further supported tolerance index (APTI) values. results suggest should be planted Bogotá low order promote its long-term survival support ecosystem services.

Environmental changes induced by urbanization may significantly alter plant survival strategies, thereby introducing uncertainties in their ability to withstand extreme heat. This study, centered on Jinhua City, distinguished urban, suburban, and rural areas represent the various intensities of urbanization. It examined leaf function properties evergreen deciduous trees common these regions, focusing branch characteristics. Employing an analysis variance (ANOVA), principal component (PCA), path (PA) functional traits climatic factors each region, this study assessed impact strategies. By tracking from June August, it explored capacity plants acclimate urban-warming-related heat stress across different gradients. The findings revealed that thickness (LT) stomatal size (SS) initially decreased then increased, whereas specific area (SLA) tissue density (LTD) first rose declined, urban regions. From wood (WD), chlorophyll (Chl) content, LTD, dry matter content (LDMC) SLA water (LWC) diminished, all PCA suggested there was no significant change resource allocation strategy (p > 0.05), with drought tolerance reduced suburbs gradient < 0.05). During summer, high temperature, were predominantly biased towards slow-return, conservative particularly among species.
