§ In Memory of Irena Naydenova

In this research, we focused on the following question: What element can be used for phylogeography and phylogenetic studies for all species using results of the genome-wide analysis (GWA) of numerous model organisms (e.g., Homo sapiens, Mus musculus, Drosophila melanogaster)? We especially paid attention to the average mutation rate variation in the DNA fragment size across alleles from diverse loci (i.e., related to length-dependent mutation processes). Over the past 30 years, all molecular markers have been developed from the fundamentally different mechanisms of four mutations: single-nucleotide polymorphisms (SNPs), simple sequence repeats (SSRs), insertions–deletions (INDELs), and chromosome aberrations. The challenge is to accurately fix the molecular clock for size-variant DNA marker data to uncover the phylogeographic histories of many plants and animals. In this paper, we provided a lot of examples from a Homo sapience to a forest tree from Pinus genus, illustrating the importance of differentiating between molecular markers, their origins, and the locus molecular size to better calibrate the molecular clock for back-in-time simulation analyses.

The article deals with the methodology for detecting and monitoring of wildfires with remote sensing data. The development’s purpose is to demonstrate the ways and methods of using free satellite data, as well as their practical application. We selected NASA’s largest fire monitoring platform, which offers free access and data from the European Space Agency’s Sentinel 2 satellites, for this purpose. This paper presents an overview of the physical basis for forest fire detection and provides a comparative study of the application of various satellite systems and equipment in the process of managing forest fire risks.

Perennial flowering plants are important parts of the urban green spaces with their beautiful flowers, colours and foliage. The purpose of the study was to evaluate the blooming stage and vegetative growth parameters for 12 perennials flowering taxa of Digitalis purpurea and Gaillardia sp. in the agro-ecological conditions of Kosovo. During the 2022–2023 growing periods, the object of research in our experimental field were totally 12 taxa. The experiment was ′Randomized block′ type with four replications and 200 plants for each cultivar. All taxa were studied for: beginning and end of the flowering stage, features of petal fusion/ligules per flower head, flower opening stage, colour of flowers, dynamic of growth in length of flower stems, diameter of flower stems, number of flower stems per plant, fragrance of flowers. Digitalis cultivars and Gaillardia sp. have demonstrated high ornamentally and long period with flowers, good growing, leaves and flowers of different colours. Because of their good performance, studied taxa deserve more important place in public green spaces in the context of greater sustainability in urban landscape and should be included in the design and planting structure in Kosovo.

In this study, we examined the diversity of bird populations in an agricultural environment in Northern Algerian Sahara (Ghardaia province) over a period of 9 months. Using the point count technique, we collected data on birds at different levels of vertical stratification based on the number of cultivated plant species. An analysis of variance was used to assess the impact of plant strata number and cultivated species number on species richness and bird abundance. During this study, 35 bird species belonging to 7 orders and 18 families were identified. The highest values of Shannon-Wiener diversity index (H’ = 2.804), Simpson index (D = 0.913), and Margalef index (D = 4.761) were observed in the most complex areas. The differences in the number of species and abundance were significant between the different levels of complexity in agricultural environments, with areas having three vertical plant strata (trees, shrubs, and herbaceous plants) and a greater number of cultivated plant species hosting the highest number of bird species and displaying high populations.
