20.500.12556/RUL-173214 Epizoohorija rjavega medveda (Ursus arctos) v Sloveniji Epizoochory by brown bears (Ursus arctos) in Slovenia Rjavi medved na svojem kožuhu širi rastlinske vrste, ki so prilagojene na epizoohorijo. S pomočjo fotopasti in analize fotografij smo dokumentirali prisotnost rastlinskih plodov in semen, pritrjenih na medvedov kožuh. Na podlagi prepoznanih morfoloških značilnostih smo potrdili prisotnost rodu repincev (Arctium sp.) in vrste lepljive kadulje (Salvia glutinosa). V delu smo pripravili morfološko, ekološko in fenološko primerjavo repincev in izpostavili njim skupno epizoohorno prilagoditev v obliki kavljastih ovojkovih listov. Druga najpogostejša vrsta je bila lepljiva kadulja, ki se na medvedov kožuh prime z lepljivimi, adhezivnimi površinami. Epizoohorija pri medvedu doslej še ni bila raziskana, prav tako pa zoohorijoše niso raziskovali s foto-pastmi. Ugotovili smo, da rjavi medved prispeva k širjenju semen preučevanih vrst, kar smo podprli s slikovnimi dokazi iz foto-pasti. Rezultati kažejo, da je epizoohorija najpogostejša pri odraslih samcih medveda ter v obdobju poznega poletja in celotne jeseni. Prav tako smo opazili, da se epizoohorija pojavlja nekoliko pogosteje na sprednjih nogah medveda, nato pa na glavi, čeprav razlike niso bile statistično značilne. Naša raziskava potrjuje, da so lahko posnetki zbrani s pomočjo foto-pasti uporabni tudi za raziskovanje epizoohorije. The brown bear spreads plant species adapted to epizoochory through its fur. Using camera traps and photo analysis, we documented the presence of plant fruits and seeds attached to the bear's fur. Based on the identified morphological characteristics, we confirmed the presence of the genus Arctium and the species Salvia glutinosa. In this work, we prepared a morphological, ecological and phenological comparison of the Arctium species and highlighted their common epizoochory adaptation in the form of hooked sheath leaves. The second most common species was Salvia glutinosa, which adheres to the bear's fur with sticky adhesive surfaces. Epizoochory in bears has not yet been studied, and zoochory has not yet been studied using camera traps. We found that the brown bear contributes to the spread of seeds of the studied species, which was supported by visual evidence from the camera traps. The results show that epizoochory is most common on adult male bears and during late summer and throughout autumn. We also found that epizoochory occurs most frequently on the bear's front legs, followed by the head. Our study confirms that camera-trap images can also be useful for studying epizoochory in animals. rjavi medved Ursus arctos epizoohorija raznašanje semen brown bear Ursus arctors epizoochory seed dispersal true false false [A.
