Abstract
- Certain aspects of the red fox (Vulpes vulpes Linnaeus, 1758) and brown hare (Lepus europaeus Pallas, 1778) population dynamics in the Autonomous Province Vojvodina (Serbia) were analysed on the basis of the available data from 1978-2015. Red fox culling was taken into account as a factor affecting the abundance of brown hares. In that period, during regulated hunts a total of 399,976 foxes were culled and the annual average was 10,526 (SD = 2985). Brown hare spring counts showed fluctuations during the research period and showed a declining trend in the number of individuals. The red fox was selected for the study as the most abundant predator in this area, having the most impact on brown hares. Also, in 2010 a nationwide vaccination campaign against rabies was conducted, leading to an increase in the numbers of red foxes. However, while this led to a rise in the numbers of red foxes, the cull remained nearly the same in the following years. Analysis of the relationship between the numbers of brown hare and the red fox cull in 1978-2009 and 2010-2015 showed a significant difference in their ratio. This study shows that the numbers of red fox increased significantly following the rabies vaccination. Consequently, this is a significant factor that is affecting the brown hare population. Also, it is evident that the red fox cull needs to be increased in order to maintain the natural balance.<br />Na temelju raspoloživih podataka iz 1978. do 2015. u Autonomnoj pokrajini Vojvodini (Republika Srbija) analizirana je dinamika populacija lisice (Vulpes vulpes linneus, 1758) i zeca običnog (Lepus europaeus Pallas, 1778). U obzir je uzet odstrel lisice kao čimbenika koji utječe na brojnost zečeva. U tom je razdoblju tijekom redovnih lovova odstrijeljeno ukupno 399 976 lisica, a godišnji prosjek iznosi 10 526 (SD = 2985). Podaci proljetnog prebrojavanja zečeva pokazuju fluktuacije tijekom istraživačkog razdoblja i trend opadanja njihova broja. za istraživanje je odabrana lisica kao najbrojniji grabežljivac na ovom području, s najviše utjecaja na zeca običnog. Također, tijekom 2010. godine provedeno je cijepljenje protiv bjesnoće diljem zemlje, što je dovelo do porasta broja lisica. No dok je broj lisica porastao, u sljedećim je godinama odstrel ostao gotovo jednak. Analize odnosa između zeca običnoga i lisice od 1978. do 2009. i od 2010. do 2015. pokazuju znakovitu razliku. Ovo istraživanje pokazuje da je broj lisica znatno povećan nakon kampanje cijepljenja protiv bjesnoće. Slijedom toga ovo je važan čimbenik koji utječe i na populaciju zeca. Također, očito je da se odstrel lisica mora povećati kako bi se održala prirodna ravnoteža.
