In this study, an extracted
Stachys scardica Hayek
leaves in the Eastern Region of Kosovo is used to enhance its value as a mild steel corrosion inhibitor in 1 M HCl medium. The electrochemical ...experiments indicate that the extract provides excellent corrosion protection, with a highest value of ≈ 92% in the inhibitor at a concentration of 600 mg/L. The potentiodynamic polarization plots show that the extract has a mixed response, reducing the strongly the current density in the presence of 600 mg/L inhibitor. The “inhibitor” molecules of SSH extract follows the Langmuir adsorption isotherm, with an adsorption energy of −15.29 kJ/mol due to interaction with the metals surface. Density functional theory, molecular dynamic, and monte Carlo theoretical investigations corroborate earlier experimental findings. The analysis of the radial distribution function from the Molecular dynamic trajectory provides compelling evidence of a prominent peak occurring at a distance of < 3.5 Å. The observed robust adsorption is primarily driven by the favorable interaction between the inhibitor's oxygen atoms and the metal surface, emphasizing the significance of this specific molecular interaction in facilitating the adsorption process.
Basic patterns of most priority biodiversity areas of Kosovo that shall be considered for conservation studies are offered here. On this work, all plant taxa that are included in the Kosovarian Red ...list are analysed and their analogy is interpreted to conservation priority hotspots. Kosovo represents an important centre for Balkan biodiversity; therefore a quantitative evaluation of the importance of different priority areas for conserving plant diversity of Kosovo is very much needed. This study provides a detailed quantitative approach concerning the identification of priority areas for biodiversity conservation, using threatened and endangered plant taxa in well-known grid squares system. Used grid squares (20 × 20 km) were classified into four different groups in terms of their conservation importance. Valuation factors taken into account are IUCN based risk category, endemism as well as ecological and distributional attributes. The results indicated that there are four grid squares – D4 (0.4300), G7 (0.3910), G8 (0.2750) and E4 (0.2860), that have remarkable conservation importance. These grid squares are all located along mostly high-elevation areas of two National Parks in Kosovo. These national scale data should prove to be very appropriate and easy to follow evidence for environmental decision-making bodies as well as be used for further research.
Dalmatian sage (Salvia officinalis L., Lamiaceae) is a well-known aromatic and medicinal Mediterranean plant that is native in coastal regions of the western Balkan and southern Apennine Peninsulas ...and is commonly cultivated worldwide. It is widely used in the food, pharmaceutical and cosmetic industries. Knowledge of its genetic diversity and spatiotemporal patterns is important for plant breeding programmes and conservation. We used eight microsatellite markers to investigate evolutionary history of indigenous populations as well as genetic diversity and structure within and among indigenous and cultivated/naturalised populations distributed across the Balkan Peninsula. The results showed a clear separation between the indigenous and cultivated/naturalised groups, with the cultivated material originating from one restricted geographical area. Most of the genetic diversity in both groups was attributable to differences among individuals within populations, although spatial genetic analysis of indigenous populations indicated the existence of isolation by distance. Geographical structuring of indigenous populations was found using clustering analysis, with three sub-clusters of indigenous populations. The highest level of gene diversity and the greatest number of private alleles were found in the central part of the eastern Adriatic coast, while decreases in gene diversity and number of private alleles were evident towards the northwestern Adriatic coast and southern and eastern regions of the Balkan Peninsula. The results of Ecological Niche Modelling during Last Glacial Maximum and Approximate Bayesian Computation suggested two plausible evolutionary trajectories: 1) the species survived in the glacial refugium in southern Adriatic coastal region with subsequent colonization events towards northern, eastern and southern Balkan Peninsula; 2) species survived in several refugia exhibiting concurrent divergence into three genetic groups. The insight into genetic diversity and structure also provide the baseline data for conservation of S. officinalis genetic resources valuable for future breeding programmes.
Sixteen endemic plant taxa were selected from Kosovo, according to the IUCN standards and for each taxon the risk assessment and threat category has been assigned. The taxa were compared with their ...previous status from fifteen years ago. From sixteen plant taxa, which were included in this work, four are Balkan endemics, whereas, eight of them are local endemics and four of the taxa are stenoendemics. Six of the taxa are grown exclusively on serpentine soils, five of them on limestone substrate, four of them in carbonate substrate, yet only one in silicate substrate. The work has been done based on the standard working methodologies of the IUCN (Guidelines for Using the IUCN Red List Categories and Criteria – Version 8.1). The most threatened plant taxa is
– which after its observance has only 20 mature individuals. As a result of the wild collection of the medicinal and aromatic plants, from the local population,
is about to be completely go extinct. The aim of this study was to assess the state of endemics in the threats possessed to them during the previous times, present and predicting the trends for the upcoming years.
This article presents the results of a floristic survey conducted between 2011 and 2021 on Mt. Kaznik, western Kosovo. In all, 361 plant taxa belonging to 75 families and 147 genera of vascular flora ...were recorded. These areas are dominated by serpentine soils, which are known for the increased occurrence of endemic plant taxa. Detailed analysis of chorological and biological data in conjunction with general vegetation data has highlighted the distinctive nature of Mt. Kaznik, making it a floristically important area. Of the taxa identified, 15 were classified as threatened plant taxa at the national level, while a total of 17 taxa are endemic plants. For each plant taxon, data on floristic element, habitat characteristics, life form, and general vegetation data are provided. A syntaxonomic analysis of the recorded taxa showed that they belong to nine vegetation classes, with the pubescent oak and mixed deciduous forest class Quercetea pubescentis being dominant. In addition, a floristic comparison was made between the serpentines of Kaznik and those in central and northern Kosovo. Considering the floristic importance and the high degree of diversity exhibited by the serpentines, the data presented are of particular importance to a better understanding of the floristic composition of Kosovo.
Primula veris
L. (Primulaceae) is a long lived perennial and well known pharmaceutical plant, widely collected for these reasons in almost all SE Europe and particularly in Kosovo. The aim of the ...study is to determine molecular polymorphism of cowslip (
P. veris
L.) populations from Kosovo. DNA extracted from leaves were investigated in details for presence of polymorphism. RAPD analyses were conducted using 20 different short primers. Genomic DNA amplification profiles were analyzed and processed using data labelling. Comparison between cowslip populations in genetic composition revealed that samples from Bogaj were too distinct on their own. Molecular variation was observed to be more within populations (73 %) as compared to among populations (27 %). On the other hand, genetic distance of populations revealed that the highest genetic distance is between Leqinat and Maja e Madhe. Mean values of expected heterozygosity were highest in Bogaj population, while lowest in Maja e Madhe population. The obtained results indicated that Bogaj population are more polymorphic. From the obtained data it can be concluded that RAPD markers provided a useful technique to study genetic diversity in
P. veris
L. populations. This technology allows identification and assessment of the genetic similarities and differences among plant populations.
The Association Stipeto-Convolvuletum Compacti ASS. Nova in Kosovo Serpentine vegetation of Kosovo represents a diversity which has not been sufficiently explored, yet. Kosovo's serpentine is spread ...in different parts of Kosovo at the altitudes of 400-2100 m. Large complexes with serpentine are found in the north of Kosovo, but the southern part of Kosovo is also rich in serpentine rocks and in endemic species. Using the principles and methods of the Zürich-Montpellier School we have explored the serpentine flora and vegetation of Gurana, an area in the south-east of Kosovo near the border with the Republic of Macedonia. This area has not been sufficiently researched because of the militarized border areas. During the research of these fields, we found species that were not present on the other serpentines of Kosovo. The species Convolvulus compactus Boiss. (syn. Convolvulus cochlearis) and Stipa mayeri dominate this terrain and create stands that we have classified as the association Stipeto-Convolvuletum compacti ass. nova. This association was researched during 2007-2010. Based on the results obtained and comparing them with the results of other authors, we have arrived at the conclusion that we are dealing with a new association which we called Stipeto-Convolvuletum compacti ass. nova.
In the territory of Kosovo there are many serpentine mountain massifs. The largest complexes are found in the valley of the Ibër River, and the same are continued in a discontinuous chain through ...Koznica and Golesh to the southwest of the territory of Kosovo. Vegetation on the serpentine bedrock is rich in rare species and communities, which cannot be found in the Balkans and Europe. The communities appearing on the serpentine bedrock are characteristic and important for science. They are endemic due to the presence of endemic species in their species composition. Drenica Mountain (1051 m) is part of the Central Kosovo Mountains. These terrains are situated in the central part of Kosovo, between Çiçavica, Kosovo plain (Golesh), Llapusha, the Carraleva Mountains and the Anadrini region. A considerable part of these areas consists of serpentine bedrock, which is covered by interesting flora and vegetation. In the vegetation of Drenica Mountain 10 communities have been identified. Two of them are found on serpentine bedrock: ass. Hyperico-Euphorbietum glabriflorae and ass. Potentillo-Fumanetum bonapartei. These communities belong to the open space, and are also located in other parts of Kosovo, but only on serpentine bedrock. On Drenica Mountain there are two localities where these two communities appear. In this paper we focus in particular on ass. Hyperico-Euphorbietum glabriflorae
Na Kosovu so številni gorski masivi iz serpentinita. Največje površine so v dolini reke Ibër. Nadaljujejo se v prekinjeni verigi skozi Koznico in Golesh proti jugozahodnem delu Kosova. Vegetacija na serpentinitu je bogata z redkimi vrstami in združbami, ki ne uspevajo nikjer drugje na Balkanu in v Evropi. Te združbe na serpentinitu so pomembne, ker vsebujejo endemične vrste. Drenica (1051 m) je del osrednjega gorovja na Kosovu. To območje se nahaja v osrednjem delu Kosova, med kraji Çiçavica, Golesh, Llapusha, gorovjem Carraleva in območjem Anadrini. Precejšen del območja je na serpentinitu. V vegetaciji gore Drenica je najdenih deset združb. Dve sta na serpentinitu: asociacija Hyperico-Euphorbietum glabriflorae in asociacija Potentillo-Fumanetum bonapartei. Najdemo ju na odprtih rastiščih. Na Drenici sta dve najdiščiteh dveh združb. V članku je predstavljena predvsem asociacija Hyperico-Euphorbietum glabriflorae
