1. 31. Spatiotemporal competition patterns of Swedish roe deer and wild boar during the fawning season

   University essay from SLU/Dept. of Ecology

   Author : Staffan Melberg; [2012]
   Keywords : Sus scrofa; Capreolus capreolus; interspecific competition; predation; spatiotemporal;

   Abstract : Abstract This study was performed on Bogesund research area, Sweden, in order to determine whether wild boar (Sus scrofa) predates on fawns of roe deer (Capreolus capreolus) and if the spatial and temporal patterns of roe deer are related to wild boar activity. A behav-ioural response is beneficial for many organisms when they are exposed to interspecific competition. READ MORE

3. 32. Effect of conventional bridges on deer-vehicle accidents

   University essay from SLU/Dept. of Ecology

   Author : Bruno Alves; [2012]
   Keywords : conventional bridges; deer-vehicle collisions; fauna adaptations; moose; roe deer; traffic mortality; wildlife passages;

   Abstract : This study evaluated whether the density and design of conventional bridges affected the frequency of reported deer-vehicle collisions along a given road or railroad section. I used official accident data from roads for 2008-2010 and from railways for 2001-2010, data on bridges and infrastructure together with digital topographic information, and estimates of regional abundances of moose (Alces alces) and roe deer (Capreolus capreolus) to develop generalized linear models of the parameters influencing the occurrence of deer-vehicle collisions.

4. 33. Predator community and prey dynamics : a case study of roe deer and re-colonizing fox, lynx and wolf

   University essay from SLU/Dept. of Ecology

   Author : Ugo Arbieu; [2012]
   Keywords : Canis lupus; Capreolus capreolus; cumulative incidence function; competing risks; Cox proportional hazards; Lynx lynx; population dynamics; survival analysis; Vulpes vulpes;

   Abstract : The role of predation is a central question in ecology and population dynamics. In South-central Sweden, the predator community has gone through drastic changes over the last fifty years with the progressive recovery of three large predators: the fox (Vulpes vulpes), recovering after a sarcoptic mange (Sarcoptes scabiei) outbreak, the lynx (Lynx lynx) and the wolf (Canis lupus), the two latter re-colonizing the region after a massive population persecution at the beginning of the 20th century.

5. 34. Six years of estimating roe and fallow deer density with distance sampling at the Koberg estate

   University essay from SLU/Dept. of Ecology

   Author : Petra Walander; [2012]
   Keywords : distance sampling; line-transect sampling; fallow deer; roe deer; inventory methods; detection function; density; encounter rate; death rate;

   Abstract : Data about the big ungulates, particularly the European fallow deer (Dama dama dama) and the European roe deer (Capreolus capreolus) have been collected at the Koberg estate (Västra Götaland County, Sweden) using distance sampling as the inventory method. The project has been running for six years (2007 – 2012) and this is the fist time where all data from all years has been merged in one study. READ MORE

6. 35. Konkurrens mellan rådjur och dovhjort

   University essay from SLU/School for Forest Management

   Author : Alexandra Agnrud; [2011]
   Keywords : Förvaltning; Klövvilt; Viltvård;

   Abstract : The main purpose of this report is a first step to cover the scarcely investigated subject of interspecific competition between roe deer, Capreolus capreolus, and fallow deer, Dama dama. The report focuses on the distance between individuals of roe and fallow in the study area as well as which factors that is affecting the variation in distance depending on fallow deer group size and changing population density over time and in two areas.
