Abstract:Namen magistrske naloge je ugotoviti nekatere morfološke in ekološke značilnosti kamniške murke (Nigritella lithopolitanica). Naredili smo popise vrste na več lokacijah po Sloveniji in populacije primerjali med seboj. Zanimal nas je tudi vpliv človeka in ogroženost vrste. Kamniška murka uspeva samo v Kamniško-Savinjskih Alpah in Karavankah, zato so vsa raziskana rastišča s teh lokacij. Popisali smo populacije vrste na 10 različnih rastiščih v dveh zaporednih letih. Leta 2014 smo izvedli meritve na lokacijah Krvavec, Menina planina, Peca, Uršlja gora ter Golte. Leta 2015 smo izvedli meritve na lokacijah Tegoška planina in Velika planina; meritve na lokacijah Krvavec, Golte ter Uršlja gora smo ponovili; na lokaciji Krvavec smo izbrali drugo rastišče. Rastišča smo med seboj primerjali po nadmorski višini, višini travne ruše, globini prsti ter velikosti in gostoti populacije. Populacije smo med seboj primerjali z nekaterimi morfometričnimi meritvami. Na vsaki lokaciji smo izbrali 20 primerkov, izmerili višino rastline, dolžino socvetja, dolžino in širino listov, število cvetov in listov ter višino listne rozete. Na vsaki lokaciji smo poiskali največjo gostoto primerkov, ki smo jih našli v obsegu kvadratnega metra, in jih prešteli. Rastišča so bila glede vrstne sestave večinoma podobna. Kamniška murka uspeva na sončnih pobočjih travnikov in pašnikov na nadmorski višini med 1400 in 1800 m nadmorske višine. Najdemo jo tudi višje. Vrsta uspeva na plitvih, revnih tleh, ponekod raste tudi v skalnih razpokah ali tik ob skalovju, kjer je prst plitvejša. Travna ruša je nižja, v povprečju visoka 6,9 cm. Na mestih z višjo travno rušo je bilo opaženih manj primerkov, gostota je bila manjša. Največjo gostoto smo zaznali ob golem skalovju, nizki travni tuši in v plitvejši prsti. Glede na nadmorsko višino ni bilo razlik v morfoloških značilnostih kamniške murke. Prav tako morfologija in pojavljanje vrste nista odvisna od bližine človeka in njegovih aktivnosti. Na vrsto močno vpliva sukcesija, saj je bilo najdenih manj primerkov na območjih z višjo travno rušo v primerjavi s tistimi z nižjo travno rušo. Med letoma 2014 in 2015 nismo opazila večjih razlik med populacijami, kar še posebej velja za lokacije, kjer smo ponovili popise. Zaključimo lahko, da kamniška murka uspeva na visokogorskih travnikih in pašnikih, kjer so rastišča vrste zelo podobna. Na vseh lokacijah raste v podobnih pogojih. Z meritvami smo pridobili želene morfometrične podatke za vrsto in ekološke značilnosti rastišča.

Title:Some morphological and ecological characteristics of selected populations of nigritella lithopolitanica
Abstract:The purpose of the thesis was to determine some morphological and ecological characteristics of the Nigritella lithopolitanica. I made an inventory of species at several locations in Slovenia and compared the populations to each other. My interest was also in the impact of humans and endangerment of species under study. Nigritella lithopolitanica grows only in the Kamniško-Savinjske Alps and the Karavanke Alps. Within its distribution area I studied 10 different locations in two consecutive years. In 2014, I conducted measurements at locations Krvavec, Menina planina, Peca, Uršlja gora and Golte. In 2015, I conducted measurements at locations Tegoška planina and Velika planina, and repeated measurements for location of Krvavec, Golte and Uršlja gora, however, on location Krvavec I have chosen a different site. I compared all location according to altitude, the height of turf, soil depth, size and density of the N. lithopolitanica population. I also compared morphometric characteristics of plants from various populations. At each location I measured the total height of plant, length of inflorescence, the length and width of the leaves, the number of flowers and leaves, and the amount of rosettes. In every population I evaluated the highest abundance of plants on one square meter. Habitats of N. lithopolitanica had similar characteristics and exhibited similar species composition. Nigritella lithopolitanica thrives on the sunny slopes of meadows and pastures at altitudes of between 1,400 and 1,800 m a.s.l. It can be found even higher. Species grows in nutrient-poor, shallow soils; sometimes in rock fissures or next to larger rocks. Turf height was on average 7 cm high. In sites where higher turf was observed, the plant density was lower. In sites with succession starting I found fewer individuals. Related to the altitude, there were no differences in morphological characteristics of N. lithopolitanica. Also morphology and appearance of the species does not depend on the proximity of sites with stronger human activities. Between 2014 and 2015, I have noticed major differences between populations, even in locations where I repeated the inventories. In conclusion, Nigritella lithopolitanica thrives on mountain meadows and pastures, where the habitat types are very similar to each other. In all locations it grows under similar conditions. From the measurements, I obtained valuable morphometric data for species and ecological characteristics of its habitat.
