AB  - 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.

AB  - Urban trees play a vital role in mitigating climate changes, maintaining the sustainability of ecosystems. This study focuses on the assessment of the resilience of cherry plums to climate changes, a fruit-bearing species that offers diverse ecosystem services within multifunctional urban and suburban landscapes. This study examines flowering and fruiting in the context of climate characteristics, expressed through the Day of the Year (DOY), Growing Degree Days (GDDs), and a yield over 17 consecutive years. The results indicate significant shifts in the DOY but not in the GDD, apart from the end of flowering. The onset of flowering was earlier and the end postponed, extending the phenophase by an average of 4 days. The cherry plum's yield was unaffected by climate changes, including extreme events like a late-spring frost. The stability of the cherry plum was confirmed by the phenological patterns of the bullace (cherry plum and blackthorn hybrid) exhibiting repeated flowering in the warmest year of 2023. The cherry plum is an adaptive species, with a high adaptability to a changing climate and a high resistance to late-spring frosts; thus, it is a favorable choice in urban design and planning, demonstrating resilience to climate shifts and thriving in polluted urban environments. It is especially appreciated for multiple ecosystem services: biodiversity conservation in natural and semi-natural areas, yielding good provisions in challenging environments, and the preservation of ornamental values through an extended flowering phenophase.

AB  - The research aims to assess the significance of early (winter) jasmine as a fundamental component within Belgrade's urban green infrastructure (UGI) in Serbia. Through a specific case study, it investigates the intricate interplay between climate, biodiversity, and vegetation across spatial and temporal scales influenced by climate change. The study analizes the layout of UGI, its various spatial typologies, and the importance of relation between these characteristics, morphology and phenology for the social and cultural context. Results demonstrate that Weeping Winter Jasmine, particularly during its cold-season flowering phase, enhances visual appeal and attractiveness without conflicting with ethical, spiritual, or cultural values. Morphological analysis of 2,250 flowers revealed a distinction between trimmed and free-growing plants, yet differing characteristics did not impact flowering abundance or visual perception. Flowering phenology was monitored across the municipalities of Savski venac, Vra & ccaron;ar, and & Ccaron;ukarica to assess shifts in flowering patterns. Over the autumn, winter, and spring of 2022/2023, 30,925 phenological observations were recorded, while 125,600 from the period 2007-2022 were utilized to determine key flowering phases and events important for landscape design. Cluster analysis delineated location 3 from locations 1 and 2, which share similarities and are influenced by the urban heat island (UHI) effect, confirming phenological changes are a prominent indicator of climate change. Despite belonging to the oldest group, location 3 individuals exhibited the longest flowering phenophase, commencing 54.5 days earlier and concluding 15 days later compared to the previous sixteen-year period. The study confirmed the importance of Jasminum nudiflorum Lindl. as a UGI element in Belgrade, sustaining vibrant and cascading displays throughout the colder months and maintianing social and cultural contribution of the location amidst climate change.

AB  - The study focuses on describing key events in the flowering phenophases of woody taxa that promote practical landscape sustainability and design planning. Apart from the beginning of flowering, the full development and the duration of phenophases are important for landscape architecture, consumers, and pollination. The phenological patterns of 13 woody taxa were monitored for 16 years through 90,860 phenological observations from the BBCH scale for the period 2007-2022. Growing degree days were determined by combining phenological and climatic data and a linear trend was used to assess phenophase tendencies. Mann-Kendall and Sen's slope tests and Spearman's correlation coefficient were used to assess statistical significance. Shifts in flowering indicated warming trends, reflecting various changes in phenology. Early flowering taxa were affected the most, but plants shifted phenophases in both directions (earlier and later in the year). Repeated flowering (and occasionally fruiting) and even third flowering, as seen in 2022, can significantly affect biodiversity and lead to plant-pollinator asynchrony and changes in ecosystem functioning, ecological interaction, and landscape design. A list of native and introduced taxa and their adaptation mechanisms to climate change are provided and can be used for sustainable landscape design and nature-based solutions in landscape architecture.

AB  - Norway spruce (Picea abies (L.) H. Karst.) is one of the ecologically and economically most important species in European forestry. According to the latest genocenological tests, environmental factors have a significant influence on the species' survival, and there is no decrease in variability in the periphery of its areal, thus the research of its resilience requires work on "plus" trees. The paper analyzed differences in thermal data of leaves in the sun and shade, trunk bark in the shade, and control surfaces in the sun: dry grass, dry soil, asphalt, and concrete, to obtain data on temperature differences as indicators of species resilience and to understand the impacts of local climate change in mountainous regions. In the summer of 2022, surface temperatures were recorded with a thermal camera on Mount Cemernik in Southeastern Europe. Monitoring and analysis of air temperatures included interpolations using a digital elevation model (DEM) and was based on the percentile method. The research results confirm significant differences between the temperatures of leaves and control surfaces. The importance of this paper is in the wide application of selected, resilient, Norway spruce "plus" trees in forestry, landscape architecture, and horticulture in Southern European habitats where scenarios predict that the climate will change, and the Norway spruce will move north.

AB  - Identification and analysis of proliferated cones in conifers has both theoretical and practical significance, particularly in systematic and taxonomic investigations, but also in the study of population and individual variability within a species. Comparative morphological-anatomical studies of reproductive organs can contribute to solving many issues in phylogeny and can iden- tify abnormal phenomena in cone formation. In light of the value of such information, this paper presents the results of monitoring European larch Larix decidua Mill. cone proliferation in Serbia over a 24-year period, with the aim of studying cone apical meristem activity, which usually is limited. Cone proliferation was confirmed by comparative morphological and genetic-physio- logical analyses of cones from European larch growing in the Arboretum of the Faculty of Forestry in Belgrade, at ages of 41, 51, and 65 years old.

AB  - This paper analyzes the morphological and dendrometric characteristics of three 97 years old European spruce trees, on Čemernik mountain, in the municipality of Crna Trava, where European spruce is not autochthonous. The examined parameters were compared with 5 test European spruce trees, aged about 50 years, which are grown in the population, within a radius of 100 m, in identical environmental conditions. The results of this study confirm the excellent vitality of hundred-year-old trees at the researched location, which can be brought into direct correlation with the current climate changes. The selected trees have confirmed the best combinatorial ability, which is why they stand out as a good base for selection and production of planting material for establishing purpose culture, afforestation, application in landscape architecture, and also for timber production. The research confirmed that the analyzed hundred-year-old spruce trees are in excellent condition and high decorative value, with a crown formed from the ground, which is why they are proposed for protection as a natural monument of botanical character.

abstract = "This paper analyzes the morphological and dendrometric characteristics of three 97 years old European spruce trees, on Čemernik mountain, in the municipality of Crna Trava, where European spruce is not autochthonous. The examined parameters were compared with 5 test European spruce trees, aged about 50 years, which are grown in the population, within a radius of 100 m, in identical environmental conditions. The results of this study confirm the excellent vitality of hundred-year-old trees at the researched location, which can be brought into direct correlation with the current climate changes. The selected trees have confirmed the best combinatorial ability, which is why they stand out as a good base for selection and production of planting material for establishing purpose culture, afforestation, application in landscape architecture, and also for timber production. The research confirmed that the analyzed hundred-year-old spruce trees are in excellent condition and high decorative value, with a crown formed from the ground, which is why they are proposed for protection as a natural monument of botanical character.",

AB  - Automotive traffic in cities is considered one of the permanent and key sources of various types of pollution in the urban environment. Urban roads have a particularly negative impact on the climate of the city. Large areas under asphalt cause overheating of cities, as a result of increased temperature and decreased air humidity, thus affecting the overall urban comfort. Roadside green spaces are elements of the city structure that directly contribute to the mitigation of negative consequences produced by the city traffic. Plant material, as part of green spaces, significantly contributes to the improvement of environmental quality, above all, benefiting the urban microclimate. The information on the plant cover of green spaces (the percentage share, especially of woody plant material) and their dendrological structure for the intensity of air temperature and humidity modification as the most important climate characteristics of the city are of great importance in the process of planning and management of urban green spaces. This paper investigates the impact of plant cover and dendrological structure of roadside green spaces in the area of Belgrade on the modification of air temperature and humidity in the immediate urban environment. The results and conclusions of this paper provide guidelines for the process of planning, management, design and establishment of roadside green spaces in order to adapt cities to climate change.

AB  - The analysis of spatiotemporal changes of temperature extremes in Serbia, based on 18 ETCCDI indices, was performed using daily minimum and maximum temperature observations from 26 meteorological stations over the period 1961-2010. The observation period was divided into two sub-periods (1961-1980 and 1981-2010) according to the results of the sequential Mann-Kendall test. Temporal trends were evaluated by a least-squares linear regression method. The average annual minimum temperature displayed a mixed pattern of increasing, decreasing, and no trends over 1961-1980 and a significant increasing trend over 1981-2010 across the whole country, with a regionally averaged rate of 0.48 degrees C per decade. The average annual maximum temperature showed a decreasing trend during 1961-1980 and a significant increasing trend at all stations during 1981-2010, with a regionally averaged rate of 0.56 degrees C per decade. Hot indices exhibited a general cooling tendency until 1980 and a warming tendency afterwards, with the most pronounced trends in the number of summer and tropical days during the first period and in the frequency of warm days and nights in the second. Cold indices displayed a mostly warming tendency over the entire period, with the most remarkable increase in the lowest annual maximum temperature and the number of ice days during the first period and in the frequency of cool nights during the second. At most stations, the diurnal temperature range showed a decrease until 1980 and no change or a slight increase afterwards. The lengthening of the growing season was much more pronounced in the later period. The computed correlation coefficient between the annual temperature indices and large-scale circulation features revealed that the East Atlantic pattern displayed much stronger association with examined indices than the North Atlantic Oscillation and East Atlantic/West Russia pattern.
