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.
