Does the red fox population reflects on the roe deer populations? : An analysis of three regions in Sweden (English)
Abstract [sv]

Osämja mellan människan och rovdjuren har funnits sedan vi slutade jaga och började bruka jorden och bedriva lantbruk. En av de absolut viktigaste faktorerna som bestämmer vart en art förekommer, hur stark en stam är och hur den förändras över tiden, är predation. I svensk historia har både rådjurs (Capreolus capreolus) och rödräven (Vulpes vulpes) båda populationer varit nära nationell utrotning. Syftet med uppsatsen är att ta reda på om räven har någon påverkan på rådjurspopulationen. Detta görs genom att analysera avskjutningsstatistik från viltdata.nu i tre olika län med liknande klimat och innehåller samma arter av predatorer. Analysen gjordes med korrelationsanalys. Dock var det inget utav resultaten som visade någon signifikans. Dessa olika resultat i de olika län tyder på att det finns andra faktorer än räven som påverkar rådjurspopulationen.

Abstract [en]

A conflict between humans and predators has existed since man stopped hunting and started with agriculture instead. We know today that one of the most important factors influencing the distribution and abundance of a species is predation. Over the last two? centuries, both the roe deer (Capreolus capreolus) population and the red fox (Vulpes vulpes) population have been very close to extinction in Sweden. The purpose of this study was to determine if the red fox population affects the roe deer population. This was done by analyzing hunting statistics from viltdata.nu in three different regions with similar climate and with the same type of carnivores. The analysis was performed using correlation analysis. None of the relationships between roe deer and the fox in the three different areas was significant. This indicates that there are factors other than predation by fox that influence the deer population.
