“…Most of the herb layer species at the study site show relatively distinct distributions of peak growth over a period of roughly four months — from February to May. The conclusion of Huang et al (2019), stating that the temporal differentiation of growth phenology is random among woodland species, seems counterintuitive if compared to the patterns observed in natural conditions, such as by Popović et al (2016). To feature the phenology patterns in our study site, a following short note must suffice.…”

Aims: The dynamics of plant communities varies across temporal scales. A correct understanding of temporal patterns is crucial for the interpretation of monitoring outputs. Focusing on the understorey community of an ancient coppice at three temporal scales, our aims were to: (a) assess the link between year-to-year variations and a decadal successional change; (b) estimate how seasonal cyclical dynamics could interfere with the changes at interannual and decadal scales; and (c) account for the effects of coppicing restoration.

“…The highest values were in August when meteorological conditions were optimal and also the leaf was in a stage of full development and capacity. On the other hand, the total leaf chlorophyll amount and specific leaf area increased with increasing shadow (Niinemets, 2010) to compensate for photosynthetic losses (Popović et al, 2016). Bearing in mind the fact that containerized seedlings were grown in the half-shadow conditions, and their canopies overlapped, these conditions were one of the influence factors which was also reported in the research of Bielinis et al (2015).…”

Chlorophyll is the main participant in the process of photosynthesis, which content can tell about plant physiological health condition. In this research, the SPAD values of the one-year-old Sessile oak seedlings of 5 Serbian provenances were measured during June, August, and October of 2021. The measuring was performed by the SPAD device, and the data were presented through the SPAD index values. The research results confirmed that the environmental conditions where the plants grow have a dominant effect on the chlorophyll content, concerning the origin of the individuals. In further research, it is necessary to accurately determine on a greater plant sample the relationship between chlorophyll content and SPAD index values.

“…Spring ephemerals are a group of plants within the geophyte assemblage that commonly form specific vernal synisiae of the temperate forest understory or dry grassland gaps [ 58 ]. Despite their common ecological requirements, several studies confirmed subtle differences among coexisting species in terms of emergence, flowering time, photosynthetic performance, and biomass allocation to optimize the use of limited resources, specifically light before upper canopy closure [ 41 , 59 , 60 , 61 , 62 , 63 ]. The life span of dry grassland spring geophytes is limited by both predictable periodical environmental conditions (lack of light due to development of surrounding vegetation, lack of water due to beginning of dry season and presence of more competitors, overgrazing) and additional disturbances (management practices, fire events) [ 27 , 40 , 64 , 65 , 66 ].…”

Deliblato Sands is the single largest expanse of sand in Europe. It is the most fire-prone area of Serbia due to the absence of surface water, sandy soils, specific microclimate conditions, and vegetation composition. Post-fire regeneration is a long-term process that includes many aspects of vegetation regrowth and habitat recovery. In the third year following one of the disastrous fires, the growth dynamics of two geophyte species in unburned and burned sites were studied. During the growing season, burned and unburned populations of Crocus reticulatus Steven ex Adam and Iris pumila L. were assessed for growth parameters (biomass production, specific leaf area, leaf area index) and leaf-level ecophysiological traits (photosystem II efficiency, chlorophyll amount, relative water content). Species acclimated differently to changed abiotic and biotic site conditions after the fire event. C. reticulatus burned and unburned populations differed significantly in terms of flowering phenology and ecophysiological traits, whereas I. pumila burned and unburned populations differed significantly in terms of growth parameters. The findings support the assertion that geophytes are generally well adapted to environmental disturbances. Species, however, responded differently to fire-induced changes in the physicochemical and biotic environment, depending on their ecological requirements and adaptive capacity.
