    1. Microbial biofungicides as an alternative for biological protection of plants (MICROBIOFUN)

     CoordinatorSofija Kostandinovska

    Context

    Macedonia, as a developing country, relies on agricultural crops production and to increase yield promotes use of, pesticides and organic fertilizers that cause irreversible damage to agricultural lands and surrounding ecosystems. In addition, Macedonia has a large portion of contaminated soils from the heavy, chemical and mining industries (Dimovska et al., 2017). These soils are known sources of antimicrobial strains, because they are adapted to an environment with a low percentage of nutrients, and a high rate of competition between microbial members (Ivanova et al., 2015). Accordingly, Macedonia is an excellent potential source of biofungicides, but since oir knowledge on biofungicides is limited, so is their use in the creation of biopreparations (Kungulovski et al., 2017).

     

    General methodology

    Во текот на реализацијата на проектот се користи стандардна методологија која веќе се спроведува во Микробиолошката лабораторија (Yilmaz et al., 2005; Gebreel et al., 2008), како определување на влага и рН, бројност со користење на pour plate методата, изолација со метод на потег и скрининг со дифузионен метод.

    The implementation of the project will use standard methodology already used in the microbiology laboratory (Yilmaz et al., 2005; Gebreel et al., 2008), such as moisture content and pH determination, enumeration using the pour plate method, isolation using the streak method, and screening using the diffusion method.

    Aims and research questions and accompanying results

    The aim of the project is to investigate the potential of indigenous microorganisms in the control of phytopathogens.

    • Contaminated soils have more antimicrobial strains.

    80% of the total number of isolates were from contaminated soils.

    • The prevalence of antimicrobial isolates is highest in autumn.

    Contrary to the expected results, we obtained the lowest number of antimicrobial isolates from the soils in autumn (30), while the highest number was observed in winter (82 isolates).

    • The total number of bacteria is higher in contaminated soils.

    The highest number was found in REK (1567000 CFU/g) in the summer season and the lowest number in Bucim (2310 CFU/g) in spring.

    • Antimicrobial strains inhibit the growth of test phytopathogens.

    Antagonists 85, 86, 87 and 88 stand out by forming the largest zones of inhibition against phytopathogens.

     

    Contribution to science

    The microbial ecology of the contaminated ecosystems of North Macedonia is an under-researched topic outside of human safety regulations. Few data are available, and there is a great opportunity to obtain breakthrough results that would influence the ecological and biotechnological perception of North Macedonia. Such findings would serve to initiate and conduct future scientific research projects.

    Conservation importance

    The conservation value and scientific contribution are closely linked. Through data of this nature, insight into the potential of the marker for Macedonian biofungicides is possible. The market entry of such products and the displacement of classical pesticides would be of inestimable importance for the protection of the environment and for the progress towards a more sustainable agriculture.

     

    2. Evolution or phenotype plasticity in Cyclotella cavitata – the answer to ecological changes in the Ohrid Lake during the Quaternary period

     Coordinator:  Dushica Zaova

    Context

    The endemic diatom species Cyclotella cavitata has persisted in Lake Ohrid during the Quaternary period, known for numerous dynamic and intensive climate changes (Pellans & Gibbard, 2012). During the same period, the lake experienced other significant environmental changes driven by ontogenic processes such as subsequent deepening, leading to alterations in mixing processes, trophic state, and nutrient availability (Wilke et al., 2020). However, the extent to which these combined changes influence the species C. cavitata and its response remains unknown. Has the species developed mechanisms for survival to this day, and can these mechanisms help us predict its reaction to similar scenarios in the future?

    Aims and research questions

    *Determining the origin of Cyclotella cavitata?
    * Does Cyclotella cavitata found a mechanism for survival during the
    Quaternary?
    * How Cyclotella cavitata responded to the climate changes?
    * Can we recognize evolutionary events from the species morphological
    variability or were the responses only ecophenotypic?
    *Does climate influence the temporal existence of morphologies?

    Methodology

    Permanent slides from Lake Ohrid sediments up to 1300 кa were used for studying the species C. cavitata. Statistical analyses were performed in R to determine the morphological variability of the species. Statistical analyses in Canocco 5, C2, and Tlia were used to track possible morphotype-environment relationships.

    Results

    А continuous existence of the species C. cavitata during the period 1100-150 ka has been found. Detailed morphometric analyses reveal significant and permanent phenotypic variations with an irreversible character, suggesting evolutionary processes within the species. These processes were driven by local ontogenetic changes within the lake as well as global climate shifts. Generally, less intense climate cycles contributed to diversification of new morphologies without causing the disappearance of previously established ones. However, intense climatic changes resulted in morphological diversification of new taxa but in addition a extinction of previously formed morphologies was observed.

    Contribution to science

    The scientific contribution is recognized in the uniqueness for studying continuous and long-term evolutionary trends in endemic diatom species. This is possible because of the 1300 ка long and undisturbed sedimentary record of Lake Ohrid and the continuity of the existence of the living world in it.

    Conservation importance

    One of the basic requirements for adequate protection of an ecosystem is understanding its uniqueness. Therefore, knowledge about the origin and evolution of endemic species can further highlight the value of Lake Ohrid as a habitat with greatest endemic diversity. This can contribute to more adequate protection of this unique ecosystem.

    Small Grants 2022

    1. Assessment of the state of blueberry populations (Vaccinium myrtillus and Vaccinium uliginosum) and their resource and economic potential on Kozhuf Mountain

    COORDINATOR: Filip Todorov

    Summary: Blueberries in Macedonia represent significant natural resource that provides additional income for number of people. However, the systems for collection, licensing, control and monitoring are still not well developed in most of the Republic of North Macedonia which puts pressure on natural habitats and wild species and leads to unsustainable use. The aim of this project is to assess the economic potential based on sustainable usage of bilberries (Vaccinium myrtillus – European bilberry and Vaccinium uliginosum – Bog bilberry) on Kozuf  Mtn., by intensive field assessment of annual production of fruits and leaves along with chemical characterization and analysis of the importance of bilberries for local population.

    First report: In the summer period of 2022 we conducted field studies on Kozhuf mountain for evaluation of the resource potential of blueberry, and phytochemical analyses in laboratory on fruit. Samples of leaves and fruits were collected with line transect method from various localities and altitudes. Phytochemical analysis of fruits resulted in 0.52% of anthocyanins in fresh fruit complying to quality requirements (min 0.3% – Ph.Eur. 10.8). The average mass of fresh berries is 0.22g. The average production of dry leaves and fresh fruits is 12.8g/m2 and 36.29g/ m2, respectively.

     

    2.  Unveiling the wild cannabis in the territory of Macedonia

    COORDINATOR: Jovana Gjorgjievska

    Summary: Scientific interest in cannabis (Cannabis sativa L.) has grown exponentially in the last 30 years due to the discovery of beneficial phytochemicals along with the study of the human endocannabinoid system. Accordingly, changes in legislation were initiated to legalize the use of cannabis for medical purposes. Cannabis is a plant that was previously cultivated as an important industrial plant but can also be found as an autochtonous plant in North Macedonia. The purpose of the study is to investigate whether there is autochtonous cannabis in Macedonia and whether it is of commercial value, through localization of the areas where it grows, collection of plant material, and its morphological and phytochemical characterization. The obtained results will be properly disseminated and will contribute to the valorization of this plant and the development of awareness of the existence of indigenous cannabis in N. Macedonia, its importance and how to change the practice of its intentional destruction to its preservation.

    First report: During the spring and summer of 2022, field activities were carried out in all planned localities, and in 3 regions wild cannabis samples were found and identified (Pelagon region, Strumica/Gevgelija and Kočani/Probishtip/Shtip). Photo-documentation was made, plant material was collected, samples were herbarized, morphological and phytochemical characterization has started (determination of drying loss, extraction of cannabinoids and HPLC analysis to determine the content of the most important cannabinoids).

     

    3. Diversity, taxonomy and distribution of the genus Dryopteris Adans. on Mount Kozhuf – 37 years after Micevski’s “Flora

    COORDINATOR: Ana Varelova

    Summary: Dryopteris is a cosmopolitan genus of ferns, which includes species with diverse habitat ranges and morphologies. Hybridization and apomixis are the main reasons for the origin of some species, morphologically separated by fine discrete characters (Fraser-Jenkins, 2007), which make the identification process particularly difficult. The project will provide data on the distribution and diversity of the genus Dryopteris on Kozhuf Mountain, through analysis of the morphological characteristics of the species and through analysis of the ornamentation and dimensions of the spores. This research is a continuation of two decades of efforts to confirm the presence of species and the published data on the genus on а national level (Melovski, 2016), where data on Drypoteris on Kozhuf were not included. This project is also a continuation of the taxonomic research of one of the most complex genera of ferns in Europe.

    First report: Conducted 36 field visits to 27 localities, during a total of 19 days. Collected 32 specimens from Dryopteris populations, now undergoing microscopic analysis. The first impressions are that there are 3 species. Estimated state of the populations and the habitats of the populations, which for now do not have significant threats, but it requires monitoring in the coming years. Plant diversity of Kozhuf Mountain has been identified, with about 700 species identified and/or registered so far, of which about 130 are species found in 1-2 localities in Macedonia.

     

     

    4. Wet meadows in Prespa – a natural filter from pollution of Lake Prespa from artificial fertilizers

    COORDINATOR: Dragana Pelikudovska

    Summary: Wet meadows in Prespa are important ecosystems with specific biogeochemical processes that provide numerous ecosystem services: water purification, nutrient and mineral retention, carbon sequestration, rich biodiversity, etc. The main threats to these habitats come from agricultural activities, mainly through the transformation of wet meadows into arable land. The project will carry out experimental research in which the main focus will be the role of wet meadows in retaining nutrients and heavy metals from fertilizers used in agricultural production. In this way, the role of these habitats to serve as a filter for these substances that reach Lake Prespa will be emphasized, and thus the need for their appropriate management and protection in the protected area Nature Park “Ezerani”.

    First report: We surveyed 39 local inhabitants from 10 Prespa villages. The analysis of the survey provided information on the type of fertilizer that is most often used, as well as the method and amount of application. In addition, a presentation was organized for students from the Faculty of Natural Sciences and Mathematics who participated in setting up the experimental plots in the wet meadow. The fertilizing of the plots was done once in June, and before that, soil and vegetation material was collected. The second collection of soil material was done at the end of August. Some of the chemical analyzes have started, but the laboratory work will continue in the next two months.

     

     

    6. Microbial abundance in glacial lakes of Pelister National Park: Response to environmental conditions (MICRO ECO ICE)

    COORDINATOR: Nikola Radmanovic

    Summary: National parks represent particular sanctuaries for natural wonders which must be protected from the pernicious effects of humankind. This is achieved by constant monitoring of all described and valorized bio-geological resources. Thus, evaluations are required of all the macro-microscopic elements of these ecosystems. The “eyes of Pelister” are glacial lakes with little to no data regarding their microbial ecology. Microorganisms, members of these glacial ecosystems, hold key positions in the numerous biological and ecological processes (Liu et al., 2017; Liu et al., 2019). Glacial lakes are the most vulnerable elements of the biosphere, under constant erosion due to global climate changes (Jiang et al., 2019). The proposed project aims towards evaluating the heterotrophic microflora of these natural wonders, including potential anthropogenic contaminants, as functions of the physical parameters of the water and the seasonal variance in ecotope. The analysis of these unique lakes is of imperative magnitude in order to evaluate the vulnerability of these invaluable ecosystems.

    First report: The completed project activities of the period thus-far allowed an initial glimpse into the microbial ecology of the Great Lake of Pelister. Planned field activities were achieved only partially, due to impassable terrain on route to the Small Lake.  Consecutive analyses showed below-average numbers of actinobacteria, unexpected dominance of mesophiles over psychrophiles, and significant numbers of coliforms. These findings represent the first of their kind, and promise an impactful conclusion when compared to the results from the second analyses planned in this project.

     

    7. Microorganisms as indicators for contamination of mineral water from thermal springs in Republic of North Macedonia

    COORDINATOR: Ognen Boshkovski 

    Summary: Natural mineral and thermal springs are an underexplored wonder of invaluable eco-cultural value (Gorgieva and Popovski, 2007). These spring are often subject to extensive anthropogenic exploitation. Meanwhile, insignificant attention is allotted to the biodiversity of these natural treasures. Additionally, the degree of anthropogenic damage inflicted is seldom discussed outside the legislative limits of allowed contaminants. The goal of this project is to enact a thorough microbiological analysis of the mineral springs at Negorci, Proevce, Katlanovo, Stip and Debar. These particular geothermal-mineral springs represent notable cultural objects under intensive local usage. Ecologically there is currently great interest in the study of microorganisms that are able to live in extreme environmental conditions such as high temperatures and mineral concentrations. In addition, very little information about autochthonous microorganisms inhabiting such thermal waters presently exists in N. Macedonia (Sagova-Mareckova et al., 2021; Hui et al., 2021). The results may serve as specific pioneers for the category as well as cause for future conservation attempts.

    First report: All fields research was conducted and all necessary samples were collected. The previous interpretations of results indicate that certain factors such as temperature and conductivity have a great influence on the number and composition of the microflora found in geothermal springs. It can be clearly seen that the springs in Katlanovo and the two springs in Negorci have a significantly more diverse and numerous population of microorganisms, which may indicate a greater anthropogenic presence in these springs. A significant difference is also observed in the two springing points in Negorci, where in Negorci 2 there is also the presence of contaminants

     

    8. Conservation of endemic plant species from the locality Alschar

    COORDINATOR: Lina Gegoska

    Viola allchariensis
    Viola arsenica

    Summary: The project “Conservation of endemic plant species from the locality Alschar” represents a significant contribution towards evaluating the status of two very rare endemic violets Viola arsenica and Viola allschariensis. By determining the population sizes, the threats, as well as establishing the monitoring areas, it will become possible to adopt conservation measures. Until now, there haven’t been any researches for determining the sizes of the population, but this project will provide data that is necessary for assessment of the species in accordance with the IUCN methodology. Students and concerned parties will be involved in the project and will have the opportunity to attend the field work and training. A truly important part of the project is ex – situ conservation of plants within the Botanical garden of the Faculty in Skopje, through the maintenance of viable populations and by collecting seeds.

    First report: With this project, the population sizes of the endemic violas of Alchar were estimated for the very first time, and monitoring areas were placed for future monitoring. It was noted that the population size of Viola allchariensis, with approximately 33600 fertile individuals, is significantly larger than the population size of Viola arsenica, which was spotted only on one location with approximately 250 individuals. Distribution area and abundance were also calculated. Threats were identified for the habitat that seems to be under low anthropogenic influence, but the biggest threat is the potential renewal of the mining activities. As for conservation measures, ex-situ preservation was accomplished and seed material was collected
