Abstract:V diplomski nalogi smo opravili floristično in funkcionalno primerjavo dveh tipov suhih travišč v hribovitem celinskem predelu Slovenije (asociacija Scabioso hladnikianae-Caricetum humilis, razred Festuco-Brometea in asociacija Homogyno alpinae-Nardetum, razred Calluno-Ulicetea), ki sta razvita na različni geološki podlagi (karbonatna oz. nekarbonatna silikatna). Analizirali smo 30 še neobjavljenih popisov asociacije Scabioso hladnikianae-Caricetum humilis in 32 objavljenih popisov asociacije Homogyno alpinae-Nardetum. Za primerjavo florističnih razlik smo uporabili multivariatno DCA analizo. Za funkcionalno primerjavo smo uporabili model C-S-R ekoloških strategij rastlin. Za 30 rastlinskih vrst s suhih travišč asociacije Homogyno alpina–Nardetum smo določili 7 morfoloških potez (MFP), ki so nam bile v pomoč pri določitvi njihovih C-S-R ekoloških strategij. Primerjava obravnavanih suhih travišč glede na floristično sestavo je pokazala, da se suha travišča na karbonatni in silikatni geološki podlagi med sabo zelo močno razlikujejo. Medtem ko so za prva značilne predvsem bazifilne in termofilne vrste, pa druga okarakterizirajo izrazito acidofilne rastlinske vrste. Na obeh tipih travišč prevladujejo vrste s C-R, C-S ter C-S-R strategijami. Primerjava razporeditve popisov v C-S-R trikotniku na podlagi relativnih deležev posameznih C-S-R ekoloških strategij rastlin v popisih je pokazala, da imajo popisi s silikatov bolj poudarjeni komponenti S (stres toleratorji) in R (ruderalke) in lahko torej sklepamo, da so razmere na suhih silikatnih traviščih za rastline bolj stresne kot na karbonatih.

Title:Comparison of C-S-R plant strategies of dry grasslands from calcareous and silicicolous geological substrates. GraduaL Thesis, University of Maribor, Faculty of Mathematics and Natural Sciences, Department of Biology, 2009
Abstract:In this diploma thesis, floristic and functional comparison of two types of dry grasslands from the central hilly part of Slovenia (association Scabioso hladnikianae-Caricetum humilis, class Festuco-Brometea and association Homogyno alpinae-Nardetum, class Calluno-Ulicetea), which are developed on distinctive geological substrates (calcareous and non-calcareous silicolous) were applied. 30 unpublished relevés of ass. Scabioso hladnikianae-Caricetum humilis and 32 published relevés of ass. Homogyno alpinae–Nardetum were analysed. Multivariatne DCA ordination method was applied for floristic analysis. For functional comparision C-S-R model of plant strategies was used. For 30 plant species of dry grasslands from ass. Homogyno alpinaet –Nardetum we determined 7 morphological plant traits in order to determine their C-S-R strategies. Floristical comparision of analysed dry grasslands showed clear differences between relevés from calcareous and silicolous dry grasslands. While the first grassland type is characterized by basiphilous and thermophilous species, the second includes many acidophilous plant species. On both grassland types prevailed plant species with C-R, C-S and C-S-R strategies. The positions of all relevés in C-S-R ternary diagram on the basis of relative proportions of C-S-R functional types showed that relevés of silicolous dry grasslands have higher impact of S and R components from which it could be concluded that conditions there are more stressful for plants than on calcareous geological substrates.
Keywords:silicicolous dry grasslands, calcareous dry grasslands, Homogyno alpinae–Nardetum, Scabioso hladnikianae-Caricetum humilis, species composition, plant functional types, plant traits, specific leaf area (SLA), C-S-R plant strategies, multivariate analysis.
