    Balkan endemic plants of Shutman Strict Nature Reserve in Kosovo – an inventory with chorological and life-form analyses

    Mechanization in agriculture & Conserving of the resources, Vol. 67 (2021), Issue 2, pg(s) 75-78

    Balkan endemic taxa are those whose distribution is restricted exclusively to the Balkan Peninsula. The aim of the present study is to determine the number of the Balkan endemic taxa in Shutman Strict Nature Reserve in Kosovo and to presented chorological groups and life-form categories of this flora. In the investigated area are recorded 67 Balkan endemic and sub-endemic species and subspecies. The most important contributors at family rank in the Balkan endemic taxa are Asteraceae, Caryophyllaceae, Brassicaceae, Campanulaceae and Rosaceae, while the richest genuses are Silene, Achillea and Campanula. In the chorological structure of the of the Balkan endemics the
    largest numbers are from the Balkan, S European and C European chorological groups, while in the life-form spectrum of the flora hemicryptophytes and chamaephytes are the most abundant. The data of the study showed that Reserve of Shutman has a very high level of endemic species. This fact shows that Shutman Reserve is an important center of the Balkan endemic flora in the Kosovo and the Balkan Peninsula and the existence of a rich endemic flora is of great importance in the conservation of biodiversity in this area.

    Diatom endemic species in Albanian part of Ohrid lake

    Science. Business. Society., Vol. 5 (2020), Issue 1, pg(s) 35-37

    The presence of endemic species in Lake Ohrid exhibit significant spatial variation, related to prevailing climate, lake morphology and fluvial input into the lake. The high biodiversity of the lake was supported by the subaquatic inflow of cool, effects of climate change on the entire lake ecosystem, affects deep water oxygen availability, nutrient cycling and trophic linkages may yet be profound as the structure of the endemic diatom taxa. The dilution of time by time lake waters with pure spring waters is important for the oligotrophic status of Lake Ohrid and its subsequent low algae productivity. We found the highest number of endemic species at different depths from the lake shore, compared to the littoral area, where almost endemic species are either very widespread or almost absent.

    Evaluation of diatom taxa in Alpin fresh water, Valbona River

    Mechanization in agriculture & Conserving of the resources, Vol. 66 (2020), Issue 1, pg(s) 39-41

    The aim of this study is to determine the species of different diatoms genius and to evaluate the ecology status of the river. Samples were collected along the Valbona River during 2015 period. Diatoms have proven to be powerful indicators of environmental conditions with changes in species assemblages providing information on changes in environmental conditions. Many species are identified and the dominant taxa were: Diatoma vulgaris, Diatoma ehrenbergii, Diatoma mesodon, Meridion circulare, Fragilaria arcus, Fragilaria capucina, Cocconeis placentula, Cymbella affinis, Gomphonema tergestinum, Navicula tripunctata etc. Diatom communities can be described by their species composition and diversity. Based on the type of taxa and the ecological values of species, Valbona river belong to oligo-saprobic state.
