Abstract:Na območju Velenjskega hribovja se pojavljajo ekstenzivni vrstno bogati travniki. V magistrski nalogi smo proučevali fenologijo cvetenja vrst na travniku zveze Bromion ercti, habitatni tip s kodo 6210(*) Polnaravna suha travišča in grmiščne faze na karbonatnih tleh (Festuco-Brometalia) (*pomembna rastišča kukavičevk). Na izbranem travniku smo naredili 30 terenskih opazovanj na treh trajnih popisnih transektih in popisali 101 rastlinsko vrsto. Za rastlinske vrste smo zbrali podatke o barvi cveta, kot jo vidi človek in kot jo vidijo čebele ter podatke za izbrane Ellenbergove indekse (osvetljenost, temperaturo, vlago tal, pH tal, in založenost tal z dušikom). Za pridobivanje podatkov o lastnostih tal (vrednosti za pH, teksturo tal, konsistenco in vlago v %) smo izvedli analize na 15 mestih in sicer po pet vzorcev na vsakem transektu. Poleg spremljanja fenologije cvetenja, smo beležili tudi opraševalce na travniški površini. Za vse analize smo uporabili programsko opremo Microsoft Office Excel 365. Ugotovili smo, da je bilo največ cvetočih vrst popisanih v obdobju zgodnjega poletja, najmanj pa v obdobju zgodnje pomladi in pozne jeseni. Glede na barve, kot jih vidi človek, so v obdobju zgodnje in prave pomladi prevladovali cvetovi vijolične barve, v obdobju pravega poletja pa cvetovi bele barve. Največ rumenih cvetov je bilo v obdobjih zgodnjega poletja, poznega poletja in zgodnje, prave ter pozne jeseni. Največ vrst je cvetelo pred košnjo. Samo pet vrst je bilo takšnih, ki so zacvetele le po košnji. Ugotovili smo, da so razmere na travniku zmerne, uspevajo vrste gozdnega roba in celo gozdne vrste. Z opazovanjem opraševalcev smo določili 50 taksonov žuželk. Najpogostejši opraševalci so bili iz družine čebel. Z raziskavo smo prispevali novo znanje o vzorcih cvetenja in s tem k boljšemu razumevanju mehanizmov, ki omogočajo biotsko pestrost tega habitatnega tipa.

Title:Flowering phenology of extensive meadow (alliance Bromion erecti) in the area of Velenjsko hribovje
Abstract:In the Velenjsko hribovje region, species-rich extensive meadows occur due to extensive use. In the master's thesis, we studied the flowering phenology of species in the extensive meadow of Bromion erecti association. In the selected meadow, we made 30 field observations on three permanent observation plots. We have listed a total of 101 plant species. Flower colour was determined for 79 plant species, and flower colour perceived by bees was determined for 65 plant species. Data on selected Ellenberg indicator values were sampled for 94 plant species: light, temperature, soil moisture, soil pH and soil nitrogen availability. To obtain data on soil properties, analyzes were conducted at 15 sites, with five samples taken on each transect. Average values for pH, soil texture, consistency and % moisture were calculated for the samples. In addition to monitoring flower phenology, we also recorded pollinators. We used Microsoft Office Excel 365 software for all analyses. We found that most flowering species were counted in early summer, and the fewest in early spring and late autumn. Purple flowers predominated in the early spring and true spring periods, and white flowers dominated in the true summer period. Most yellow flowers occurred in early summer, late summer and early autumn, mid-autumn and late autumn. Most species flowered before mowing. Only five species flowered after mowing. We found that the abiotic conditions in the meadow are moderate, the forest edge species and even forest species thrived. By observing pollinators, we were able to identify 50 insect taxa. The most common pollinators were from the bee family. With this study, we gained new insights into flowering patterns and a better understanding of the mechanisms that enable the biotic diversity of this habitat type.
