20.500.12556/RUL-168301 Razporeditev makrofitov v Zbiljskem jezeru in v jezeru Črnava pri Predvoru Distribution of macrophytes in lake Zbiljsko and in lake Črnava near Preddvor Jezera so pomemben ekosistem za organizme, ki živijo v ali ob njem, pa tudi za človeka. Vodni makrofiti igrajo pomembno vlogo v jezerskih ekosistemih. Njihovo uspevanje je odvisno od fizikalnih, kemijskih in hidromorfoloških ter biotskih dejavnikov v jezeru. Imajo številne prilagoditve, ki jim omogočajo, da zasedajo različne ekološke niše v jezeru. V okviru magistrske naloge smo ocenjevali prisotnost in abundanco makrofitov v jezeru Črnava v občini Preddvor in v Zbiljskem jezeru v občini Medvode. Merili smo fizikalne in kemijske parametre vode kot so pH, koncentracija kisika, nasičenost s kisikom, temperatura vode in električna prevodnost. V vodi v obeh jezerih smo izmerili koncentracijo ortofosfatov in nitratov. Ocenjevali smo tudi izbrane okoljske dejavnike. Na jezeru Črnava smo popisali prisotnost in abundanco taksonov v desetih transektih, na Zbiljskem jezeru pa v 26 transektih. V obeh vodnih telesih smo določili skupno 26 taksonov. Najpogostejša vrsta v obeh jezerih je bila račja zel (Elodea canadensis), ki je v jezeru Črnava predstavljala več kot 90 % relativne rastlinske abundance. Fizikalni in kemijski parametri vode in okoljski dejavniki niso statistično značilno vplivali na diverziteto makrofitov. Lakes are an important ecosystem for organisms living in or beside them and humans. Growth of macrophytes depends on several physical, chemical, hydromorphological and biotic factors. They have several adaptations that allow them to inhabit different habitats in the lakes. In this thesis, we assessed the presence and abundance of macrophytes in lake Črnava in Preddvor municipality and Lake Zbilje in Medvode municipality. We also measured several chemical and physical parameters, such as water temperature, concentration of oxygen, saturation with oxygen, and pH, and assessed environmental parameters. We analysed the concentration of orthophosphates and nitrates in the water. 26 taxa of macrophytes were recorded in both lakes. These taxa were recorded in ten transects on Lake Črnava and 26 transects on lake Zbilje. The most common species in both lakes was the Canadian waterweed (Elodea canadensis), representing over 90% of all relative plant abundance in lake Črnava. Physical and chemical parameters of water and environmental factors did not statistically significant effect macrophyte diversity. popis jezero makrofiti abundanca monitoring lake macrophytes abundance true false false [A.
