Abstract

U posljednjih nekoliko desetljeća u Hrvatskoj i Europi je zabilježen porast brojnosti i širenje populacija zlatnog čaglja (Canis aureus) zbog čega su potrebne sofisticirane metode praćenja te vrste. Cilj ovog rada bio je procijeniti gustoću i veličinu populacije zlatnog čaglja koristeći kamere s pasivnim infracrvenim senzorom i model nasumičnih susreta (eng. random encounter model; REM) za kojeg nije potrebna identifikacija životinja na razini jedinke. Istraživanje je provedeno u državnom otvorenom lovištu IX/13 "Senj". Procijenjena gustoća populacije bila je 1.47 ± 0.41 čagljeva/km2 i brojnost c. 90–160 čagljeva. Model nasumičnih susreta doprinos je razvoju metodologije za monitoring čaglja i korisna je metoda za procjenu populacijskih parametara čaglja.

Abstract (english)

In the last several decades in Croatia and Europe, an increase in abundance and expansion of golden jackal (Canis aureus) populations have been observed, making sophisticated methods for monitoring of this species necessary. The aim of this study was to estimate population density and size of golden jackal using passive infrared sensor cameras and random encounter model (REM) that does not require individual identification of animals. Survey was conducted in state open hunting ground IX/13 "Senj". Estimated population density was 1.47 ± 0.41 jackals/km2 and abundance c. 90–160 jackals. The random encounter model adds to the methodological development of jackal monitoring and is a useful method for estimation of jackal population parameters.
