This study aims to explore how the environment affects variation and trade-offs of anatomical traits in shrub plants, contributing a deeper understanding plant survival strategies mechanisms adaptation environment. The dominant species Corylus mandshurica broad-leaved Korean pine (Pinus koraiensis) forest was selected as research subject. Current-year twigs leaves C. were collected spring (May), summer (July), autumn (September). Anatomical traits, including non-vascular column proportion (NVP), vascular (VP), phloem (PP), xylem (XP), measured for twigs, lower part petioles, upper leaf veins. We found that (1) Compared with seasons, organ type explained most four (NVP = 96%, VP 87%, PP 81%, XP 76%). Lower petioles served turning point trend tissue proportions cross-sectional structure along sequence (2) In spring, exhibits higher NVP but PP, while results are opposite those spring. Among different organs, show XP; whereas veins pattern.

Furthermore, demonstrate strategies. Future should focus on organs their connecting parts.

Urban environments are typically warmer than surrounding rural areas, providing a unique setting for studying phenological responses to climate warming. Phenological differences between urban and trees driven by local species composition. Yet, the extent which composition influences urbanization remains poorly understood. To address this, we combine manipulative experiments, satellite-derived phenology data, georeferenced tree occurrence records. Our findings show that, across Northern Hemisphere cities, in temperature sensitivity of spring areas largely urban-rural variation composition, surpassing effects preseason temperature. This pattern is particularly pronounced Asian where exhibit 0.74 ± 0.24 days/°C higher areas. In-depth analyses using experiments high-resolution satellite imagery from Beijing further demonstrate species-specific urbanization, with urban-dominant exhibiting compared ones. These that both interspecific contribute impact on patterns. study underscores importance considering when warming, especially contexts.

Aims: The functional traits of twigs and leaves are closely related to the ability plants cope with heterogeneous environments. analysis characteristics leaf thermal dissipation in riparian is great significance for exploring light energy allocation ecological adaptation strategies plant habitats. However, there few studies on correlation between twig–leaf their heat Methods: In this study, Hippophae rhamnoides Taohe National Wetland Park was research object. According differences canopy environment H. population, three habitat gradients were set: I, full sight zone; II, moderate shade III, cover zone. We studied relationship a environment. Important Findings: results as follows: from zone zone, population twig, leaf, photosynthetic fluorescence physiological demonstrated significant changes (p < 0.05). tended have thick smaller SLA short twigs, absorbed by accounted higher proportion dissipation. grow many thin high long lower than that large low slender lowest.

Abstract. Vegetation phenology and hydrological cycles closely interact from leaf species levels to watershed global scales. As one of the most sensitive biological indicators climate change, vegetation is essential be simulated accurately in models. Although Soil Water Assessment Tool (SWAT) has been widely used for estimating cycles, its lack integration with module led substantial uncertainties. In this study, we developed a process-based coupled it SWAT-Carbon model investigate effects dynamics on runoff upper reaches Jinsha River China. The modified showed reasonable performance simulation, root mean square error (RMSE) 9.89 d start season (SOS) 7.51 end (EOS).

Abstract Grassland phenology is highly sensitive to climate change. Here, we investigate the spatiotemporal patterns of start (start season (SOS)) and end (end (EOS)) dates growing quantify changes in their climatic controls over arid Central Asian grassland ecosystems during 1982–2015, which may improve model performance by considering shifts primary drivers under ongoing Our results suggest that temperature played a positive role advancing SOS date, with control on getting stronger as preseason conditions become warmer but not drier. For autumn phenology, rapid increase after 1999 combination reductions precipitation jointly contributed shift from delayed advanced EOS. The areas EOS regulated either or have changed between two subperiods. findings dynamic difference spring should be built into phenological models more accurately.
