Spolna in starostna struktura tropov navadnega muflona (Ovis orientalis musimon) na Gorenjskem

Marenk, Žiga (author), Krofel, Miha (mentor)

V raziskavi smo leta 2017 v zimsko – spomladanskem času v lovišču Bled na 5 krmiščih spremljali trope muflonov (Ovis orientalis musimon). Spremljanje je potekalo z avtomatskimi kamerami, ki smo jih namestili na drevesa ob stičinah pri krmiščih. Ugotavljali smo velikost, spolno in starostno strukturo tropov muflonov ter vzorce cirkadiane aktivnosti rabe krmišč. Ugotovili smo, da se velikost, starostna in spolna struktura tropov spreminja skozi mesece. V povprečju so bili tropi samcev večji od tropov samic z mladiči, vendar pa so bili tropi samic z mladiči najpogosteje opažena vrsta tropa na krmišču. Najpogostejša starostna kategorija tropov samic z mladiči so bile odrasle samice, najpogostejša starostna kategorija samcev pa 2 – 3 leta. Višek aktivnosti muflonov na krmiščih je bil okoli sončnega vzhoda, precej visoko aktivnost pa smo zaznali tudi okoli sončnega zahoda ter v nočnem času. Ugotovili smo, da je bilo število nočnih obiskov večje od števila dnevnih obiskov. Poleg muflonov smo beležili tudi ostale netarčne vrste na krmiščih ter njihove interakcije z mufloni.

• Title: Age and sex structure of mouflon (Ovis orientalis musimon) flocks in upper Carniola region

Abstract

Master thesis investigate the sex and age structure of mouflon flocks (Ovis orientalis musimon) in the winter – spring time in the hunting area Bled. The observations were made by video – trapping method near the feeding sites. We found out that the size age, sex structure of flocks of mouflon differs through the observed months. Average size of the male flocks were bigger than the flocks of ewes with lambs, but the flocks of ewes with lambs were more frequent in the feeding sites than the flocks of male. The most frequent age category of flocks of ewes with lambs were the adult ewes, the most frequent category in the flocks of the males were rams age of 2 – 3 years. Activity patterns showed that the mouflons were most active around sunrise and sunset and also through the night. We found out that the numbers of night – time visits of feeding sites were more often than the day time visits. Besides the mouflons we also noted the nontarget species and their interections between mouflons.
