Sezonsko spremljanje makrofitov v Šobčevem bajerju in pritoku

Kljun, Jošt (avtor), Germ, Mateja (mentor)

V magistrski nalogi smo preučevali sezonsko spreminjanje v prisotnosti in razporeditvi makrofitov v Šobčevem bajerju, pritoku in bazenu, ki se nahaja pred bajerjem. Makrofite smo štirikrat v sezoni popisovali v pritoku, bazenu in na štirih vzorčnih mestih v bajerju. Na vsakem od sedmih vzorčnih mest smo spremljali fizikalne in kemijske parametre vode, merili globino vode in opravili širšo okoljsko oceno pritoka, bazena in bajerja s pomočjo RCE metode (Ripariran Channel and Environmental inventory). Na vseh vzorčnih mestih smo štirikrat v sezoni merili tudi koncentracije nitratov ter fosfatov v vodi. V pritoku, bazenu in bajerju, smo skupno našli 22 vrst makrofitov, od tega jih je bilo 10 submerznih in 11 emerznih, ena vrsta je bila submerzna in emerzna. Vrstna sestava makrofitov se je na posameznih vzorčnih mestih spreminjala skozi sezono. Nekaj vrst je bilo takih, ki so bile na posameznem vzorčnem mestu prisotne na začetku sezone nato pa jih nismo več našli. Vrstna sestava makrofitov se je razlikovala ne le med posameznimi sezonami ampak tudi med vzorčnimi mesti. Ugotovili smo, da od vseh analiziranih parametrov (koncentracija kisika, nasičenost vode s kisikom, prevodnost, pH, koncentracija nitratov in fosfatov, globina), na prisotnost in abundanco makrofitov vpliva samo globina vode.

• Naslov: Seasonal monitoring of macrophytes in Šobec pond and its tributary

Izvleček

In this thesis, we seasonally monitored species presence and distribution of macrophytes in Šobec pond and its tributary. The tributary was one of the sample sites, and the other two were a man-made pool in front of the pond. The pond was divided into four sampling sites. We also monitored physical and chemical parameters of water and water depth. In the laboratory, we determined concentrations of phosphates and nitrates. We also made a RCA (Ripariran Channel and Environmental Inventory) inventory of a pond, a tributary, and a man-made pond. Altogether, we found 22 different species of macrophytes. 10 species were submerged, 11 were emergent and one species was both submerged and emergent. The species composition changed throughout the seasons at individual sample sites. A few species were present at the beginning of the season and then disappeared. The species composition differed not only between individual seasons but also between sample sites. We found that water depth among all parameters (oxygen concentration, conductivity, concentration of nitrates and phosphates, pH) had the greatest influence on the presence and abundance of macrophytes in Šobec pond.
