Abstract

V diplomskem delu smo raziskali cirkadiano aktivnost evrazijskega risa in njegovega plena, srnjadi in gamsa. Raziskava je potekala z metodo spremljanja živali z avtomatskimi kamerami, ki so bile nameščene v gozdovih po celotnem delu osrednje razširjenosti risa v slovenskih Dinaridih. Raziskava je pokazala, da je ris najbolj aktiven ponoči z dvema viškoma aktivnosti okoli jutranjega ter večernega mraka, ko je najbolj aktiven tudi njegov plen, to je srnjad in gams. Tekom noči sta ti dve vrsti plena manj aktivni kot ris, medtem ko je njuna dnevna aktivnost večja. Raziskava nakazuje, da ris verjetno prilagaja svojo aktivnost tudi glede na aktivnosti plena, hkrati pa tudi, da plen prilagaja svojo aktivnost glede na prisotnost risa, saj sta na območju, kjer je prisoten tudi ris, gams in srnjad nekoliko bolj aktivna podnevi, kot na območjih, kjer ris ni bil prisoten. Metoda spremljanja cirkadiane aktivnosti risa z avtomatskimi kamerami se je izkazala za uspešno, pri preučevanju aktivnosti in medvrstnih interakcij.

Secondary title:	Monitoring the circadian activity of the Eurasian lynx (Lynx lynx L.) and its prey with the help of automatic wildlife camera recordings
Secondary abstract:	The thesis investigates the circadian activity of the Eurasian lynx and its prey, roe deer and chamois. The study was carried out by monitoring the animals with automatic cameras, which were deployed in forests throughout the central part of the lynx's range in the Slovenian Dinaric Mountains. The survey showed that the lynx is most active at night with two peaks of activity around morning and evening twilight, when its prey, i.e. roe deer and chamois, are also most active. During the night, these two prey species are less active than the lynx, while their daytime activity is higher. The study shows that the lynx adjusts its activity according to the activity of its prey, but also that its prey adjusts its activity according to the presence of the lynx, as in areas where the lynx is present, the chamois and the roe deer are much more active during the day than in areas where the lynx is absent. The method of monitoring the circadian activity of lynx with automatic cameras proved to be successful, leading to the findings described above.
