Abstract:V magistrskem delu smo raziskovali povezavo funkcionalnih potez in CSR strategij rastlinskih vrst, ki sobivajo s kukavičevkami na ekstenzivnih suhih traviščih na območju Haloz (asociacija Onobrychido viciifoliae-Brometum, razred Festuco-Brometea). Izbrani kukavičevki sta bili piramidasti pilovec (Anacamptis pyramidalis, N=11) in jadranska smrdljiva kukavica (Himantoglossum adriaticum, N=9). Na popisnih ploskvicah v polmerih 0 - 10 cm, 10 - 20 cm, 20 - 30 cm, 30 - 40 cm in 40-50 cm od središča rasti osebkov, smo po izbrani metodologiji vzorčili podatke o rastlinski vrstni sestavi in tako popisali 400 ploskvic. Za ugotovitev povezave med funkcionalnimi potezami in sobivanjem vrst smo določili in analizirali izbrane morfološko-funkcionalne poteze (višina rastline in CSR strategija, začetek, konec in dolžina cvetenja). Zbrali smo tudi podatke o Ellenbergovih indeksih rastlin. Za primerjavo vrstne sestave na mikrolokacijah smo uporabili multivariatne statistične analize. V polmeru 50 cm od osebkov kukavičevk je bilo ugotovljenih 67 rastlinskih vrst. V okolici piramidastega pilovca raste v povprečju manj vrst kot pri jadranski smrdljivi kukavici. Ugotovili smo tudi, da zaseda podobne mikrohabitate na travišču, to so z vrstami srednje bogati sestoji, kjer so značilne bolj sušne razmere. Vrsta Himantoglossum adriaticum pa zaseda na travniku bolj raznolike mikrohabitate, predvsem ob gozdnem robu in, kjer je bolj gosta ruša, pa tudi na tipičnih mestih, kjer raste običajno piramidasti pilovec, ter v predelih travišča, kjer so rodovitnejša tla. Rastlinske vrste, ki rastejo v bližini piramidastega pilovca, so pokazateljice rastišč z boljšimi svetlobnimi razmerami. Rastlinske vrste, ki rastejo v bližini jadranske smrdljive kukavice so bolje prilagojene na manj svetlobe, saj so značilne za produktivnejše habitate, kjer so višji in gostejši sestoji. Za obe kukavičevki velja, da sobivata z rastlinami, ki imajo najbolj izraženo stres-toleratorsko strategijo. Medtem, ko imajo vrste, ki so v oddaljenosti do 10 cm od piramidastega pilovca, ki je sam S/SR strateg, bolj izraženo kompeticijo in vrste v okolici do 10 cm pri jadranski smrdljivi kukavici, (CR-strateg) ruderalno strategijo.

Title:A link between the functional traits and plant species coexistence in dry grasslands
Abstract:The aim of our work was to research the connection between functional traits and CSR plant strategies of the species which coexist with orchids on extensive dry grasslands in the Haloze region (association Onobrychido viciifoliae-Brometum, class Festuco-Brometea). The selected orchids were Anacamptis pyramidalis, N=11 and Himantoglossum adriaticum, N=9. On the plots in radii 0-10 cm, 10-20 cm, 20-30 cm, 30-40 cm and 40-50 cm from the center of growth of orchids we sampled the data of the plant species composition according to the selected methodology and thus sampled 400 plots. In order to establish a connection between functional traits and species coexistence we determined and analyzed selected morphological functional traits (height of the plant and CSR strategies, beginning, ending and length of flowering). We also collected data of Ellenberg's indices. Multivariate statistical analyzes were used to compare the species composition on the microhabitats. In the 50 cm radius from orchids, 67 plant species were listed. In the area of Anacamptis pyramidalis on average, there are less species growing than in the area of Himantoglossum adriaticum. We also found that A. pyramidalis occupies similar microhabitats on grassland, with medium species richness and characterized by more dry conditions. Himantoglossum adriaticum, however, occupies more diverse microhabitats on the meadow, above all along the forest edge and, where vegetation stands are more dense, as well as in typical places where the Anacamptis pyramidalis grows, and in areas of grasslands where soil is fertile. Plant species that grow near Anacamptis pyramidalis are indicators of sites with better light conditions. Plant species that grow near Himantoglossum adriaticum are better adapted to less light, as they are characteristic for more productive habitats, where is denser and higher vegetation.. Both orchids are considered to coexist with plant species that have the most pronounced stress tolerant strategy. While species that are within 10 cm of a Anacamptis pyramidalis which is the S / SR strategist have more pronounced competition and species that are within 10 cm of a Himantoglossum adriaticum (CR-strategist) have ruderal strategy.
