Adaptability and allometric relations of Acer pseudoplatanus and A. pseudoplatanus “Atropurpureum” at different urban sites are investigated in this work via the diameter at breast height (dbh), tree height, and crown width measurements, which served as ordinary least-squares regression model inputs. Differences between A. pseudoplatanus and A. pseudoplatanus “Atropurpureum,” as well as intraurban variations of trees growing at different urban site categories (park and street) and location in the same urban site category with different urban morphology characteristics, were noted. The strongest allometric relations were noted for crown width/tree height and tree height/dbh. Higher uniformity and better linear model fit were obtained for A. pseudoplatanus “Atropurpureum.” Based on allometric relations with dbh as the predictor variable, trees growing in parks were shorter and had a wider crown than street trees, whereas the same tree proportions were observed in A. pseudoplatanus.

Climate change increasingly impacts urban dendroflora, affecting plant physiology and phenological phases. This paper investigates the impact of changing climatic conditions on the blooming of Fraxinus ornus ‘Globosa’, a decorative form of ash that is a significant component of green infrastructure in Novi Sad, Serbia. The research, conducted over 15 years on 42 individuals in a linear planting near a large river, analyzed temperature and precipitation effects on blooming times and inflorescence characteristics The results indicate changes in the timing of blooming, earlier than recorded in the literature, suggesting that temperature variations and changes in climatic conditions have significantly influenced the phenological phases of the selected clones of globe flowering ash. Additionally, the studied individuals showed exceptional adaptation to climate change and are not considered vulnerable. This study confirmed that this cultivar of flowering ash in urban environments is a key link in the green infrastructure of cities, functioning as green corridors along river flows as a nature-based solution. The studied cultivar is an important element of cultural heritage, contributing to the recreational potential of the linear composition of the promenade, especially during the flowering phenophase, when, in addition to its aesthetic values, it has psychological effects on users of the space, offering a calming influence due to its regular canopy and planting rhythm. Additionally, this cultivar provides important ecological functions, such as offering pollen for pollinators, thereby significantly contributing to the implementation of ecosystem services.

In this research, tree sensitivity to the surrounding highly paved environment was analysed at several locations within one urban core (Novi Sad, Serbia). In the future, urban areas will become denser and will, in interaction with intensive climate change, negatively affect the urban forestry performance. Hence, in-depth understanding of the interactions between site-specific parameters, such as pavement and trees, is necessary. When conducting analyses, in this research the data was separated into four groups (0−2; 2−4; 4−6; >6 m) by two grouped parameters that define the interaction between trees and paved surfaces across the streets. The findings revealed that paved surroundings exerted the most significant effect on tree dimensions and lower on vitality. Moreover, tree height, diameter at breast height, crown width and phytopathological and entomological damage emerged as the most reliable indicators of plant stress caused by the negative influences of a paved environment. Reduced uniformity was noted for trees closer to the traffic and in areas with a narrow landscape strip. In general, the distance from the traffic has a stronger influence than the width of landscape strip on the analysed tree characteristics. Furthermore, the sycamore maple and its red leaf cultivar can be recommended for planting in highly paved areas across streets.

Given the growing impact of climate change, this study examines the flowering phenology of Rosa rugosa Thunb. in Kupinovo (Vojvodina, Serbia). Data collected over 18 years (2007–2024) were analyzed to assess changes in primary flowering, while secondary flowering was monitored from 2022 to 2025. Phenological stages were recorded every other day, and dates were converted into day-of-year (DOY) values. Heat accumulation (GDD) was calculated using daily max/min temperatures and thresholds. In 2024, R. rugosa exhibited a 37-day earlier onset and a 50.4-day later completion of primary flowering compared to previous years. The variability of key phenological events of primary flowering was observed in the interaction with climatic parameters, with regular fruiting. The species proved tolerant to heat and drought, suggesting potential range expansion. Optimal temperatures for secondary flowering were identified: abundant flowering occurred at 13.6 °C max and 4.9 °C min, while moderate flowering occurred at 9.0 °C max and 4.2 °C min. Regression analysis confirmed the positive effect of rising temperatures on flowering intensity. While freezing halted secondary flowering and damaged open buds, unopened buds remained unaffected. These findings highlight R. rugosa as a resilient, ornamental species, relevant to climate adaptation strategies, nature-based solutions, and the preservation of ecosystem services under global warming scenarios.
