20.500.12556/RUL-122922 Raznolikost vibracijske krajine znotraj istega travniškega habitata Diversity of vibrational landscapes within a specific meadow habitat Nedavni pojav biotremologije kot nove znanstvene discipline je vibracijsko komunikacijo postavil v središče raziskav. Čeprav je znano, da je vibracijsko signaliziranje ena najstarejših in najbolj razširjenih oblik komunikacije med živalmi, kompleksnost naravnega vibracijskega okolja, kjer se ta komunikacija odvija, ostaja neznana. Glavni cilj naloge je raziskati raznolikost vibracijskega okolja v travniškem habitatu in primerjati med seboj vibracijsko okolje posameznih rastlin iste vrste ter vibracijsko okolje rastlin različnih vrst na isti lokaciji, v istem habitatu – nižinskem travniku na Ljubljanskem barju. Istočasno snemanje vibracijske krajine z več laserskimi vibrometri smo izvedli zgoščeno v obdobju najvišje aktivnosti živali, ki oddajajo vibracijske signale. Hkratni posnetki rastlin Carex hirta in Galium mollugo, ki rastejo v bližini na različnih delih travnika, so pokazali, da sta sestava in abundanca vibracijske krajine odvisni tako od gostiteljske rastlinske vrste kot tudi od prostorskega položaja posamezne rastline na travniku. Med lokacijami na travniku se pri dlakavemu šašu pojavljajo statistično značilne razlike v skupnem trajanju vibracijskih signalov, pri navadni lakoti pa teh razlik nismo opazili. Na obeh rastlinskih vrstah se najpogosteje pojavljajo vibracijski signali treh vrst škržatkov (Cicadelliae), razlike pa se kažejo v prisotnosti ali odsotnosti redkih tipov vibracijskih signalov. Domnevamo, da so razlike v količini in sestavi vibracijske krajine, ki jo zaznamo z laserskim vibrometrom, posledica heterogenosti rastlinskih sestojev, geometrije in strukture rastlin in variabilnosti mikroklimatskih pogojev znotraj habitata. The recent emergence of biotremology as a new scientific discipline has placed vibrational communication into research focus. Although vibrational signaling is known to be one of the oldest and most widespread forms of communication, the complexity of the natural vibrational environment where this communication takes place remains unknown. The main goal of the thesis was to investigate the diversity of vibrational environment within the same meadow habitat and to compare the vibrational environment on individual plants of the same species and the vibrational environment registered on plants of different species within the same location. The recording of the vibrational landscape (vibroscape) was performed during the period of the highest insect activity with several laser vibrometers in lowland meadow in Ljubljansko barje. Simultaneous recordings of Carex hirta and Gallium mollugo plants growing near each other in different parts of the meadow showed that the composition and the cumulative duration of vibrational signals differs, regarding both the host plant species and the spatial position of individual plants. On Carex hirta, the amount of registered vibratory signals showed significant differences between locations, while on Gallium mollugo plants, diferences were much smaller. In both plant species, the most common vibrational signals belonged to the same three leafhopper (Cicadelliae) species and they differ in the presence or absence of rare vibrational signal types. We assume that the differences in the amount and composition of the vibroscape registered by the laser vibrometer are due to the heterogeneity of meadow plant composition, plant geometry and structure, and the variability of microclimatic conditions within the habitat. biologija vibracijska krajina raznolikost travnik vibracijska komunikacija biology vibroscape diversity hay meadow vibrational communication true false false Slovenski jezik Angleški jezik Magistrsko delo/naloga 2020-12-16 12:11:22 2020-12-16 12:11:33 2022-09-03 04:10:21 0000-00-00 00:00:00 2020 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 187546 44400387 11556.pdf 11556.pdf 1 799979CC4D5504C370F17DF37995000A 80c7022e32345af7df0c064eebcd65c7d7cdf310c265b030c171de9f3a90df92 219e73af-a1bb-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=138172 Biotehniška fakulteta 0 0 0
