Konkurrens mellan rådjur och dovhjort

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. For additional information the history of the populations, such as harvest and distribution, is also investigated. The report came to the conclusion that interspecific competition between the species do occur. The elevated distance between individuals of the two species is clearly significant. The most important factor affecting the distance seemed to be the size of the fallow groups.

Neonate mortality in fallow deer (Dama dama) in relation to bed-site selection and habitat use

The level of neonate mortality in a free ranging Fallow deer (Dama dama) population at the Koberg estate in south western Sweden was investigated using radio-tracking techniques. During this study a total of 36 fawns (17 ?, 19 ?) were captured and marked with vhf or gps radio collars; 12 fawns in 2008 and 24 fawns in 2009. The neonate mortality calculated by the Kaplan-Meier method was 23.6 % and the mortality caused by predation was low, since only 1 of 8 non-surviving fawns died from predation by red fox (Vulpes vulpes). The spatial behavior of the fallow deer neonates were examined at two different levels i.e.

Effects of brown bear (Ursus arctos) odour on the patch choice and behaviour of different ungulate species

The return of large predators to regions where they were previously extirpated has created a need for knowledge about their effect on prey species, not only their lethal but also their behavioural or risk effects. In this study the behavioural risk effects of brown bear (Ursus arctos) were tested on Fallow deer (Dama dama), roe deer (Capreolus capreolus), red deer (Cervus elaphus), moose (Alces alces) and wild boar (Sus scrofa). This was done by using patches of fur to simulate the presence of the novel predator (brown bear), a novel nonpredator (reindeer (Rangifer tarandus) and no fur as control. These three treatments were then compared. The response variables measured were increased vigilance, decreased feeding time and change in patch use.

Evaluating six crop mixes used for game fields in southwest Sweden : biomass production, fallow deer preference and species diversity

Game fields are one way to divert animals away from sensitive areas, create shelter and forage, and also to increase the biological diversity. In this study I investigated how the plant composition in six different crop mixes used for game fields affected the biomass production, biomass consumption and biological diversity at the Koberg estate in southwestern Sweden. Six experimental fields were used and each field contained six plots, approximately 1500 m2 each, that was sown with a different crop mix. The crop mixes ranged from a pure grass mix (A), 70 % grass and 30 % leguminous plants (B), 53 % grass, 21 % leguminous plants and 26 % other herbs (C), 100 % leguminous plants (D) to the most complex mixes constituting of 91 % leguminous plants and 9 % other herbs (E) and 87 % leguminous plants and 13 % other herbs (F). The fields were cut weekly during the summer in 2010, to estimate weekly biomass production.

Externa kostnader för viltolyckor

The objective of this paper is to estimate monetary and non-monetary costs for the huntercaused by deer-vehicle collisions in Sweden. These costs include losses in hunting value as wellas time and money efforts related to the handling of wildlife casualties. The calculations arebased on available statistics from 2004 on deer-vehicle collisions involving moose, deer, roedeerand wild boar and on telephone interviews with hunters involved in the tracking of injuredanimals. Altogether, the annual loss in hunting value for moose was assessed to approximately30 million SEK based on the 2004 accident statistics. For roe-deer and fallow deer, thecorresponding figure was approximately 56 million SEK and 1.2 million SEK, while wild boaraccounted for 1.3 million SEK, respectively.

Drevjaktens sekundära effekter på dovhinden (Dama dama)

I största delen av Europa är det jakt utförd av människan som är den huvudsakliga dödsorsaken för hjortdjur som till exempel dovhjort, kronhjort och älg. Men jakt kan även ha andra negativa effekter på djur än de dödliga. Forskning har visat att jakt kan påverka hjortdjurs beteende och hur de använder sitt hemområde där man bland annat sett att hjortar ökar storleken på sitt hemområde, vistas mer i skogsområden än öppna områden samt lämnar och undviker områden där det förekommer mänsklig aktivitet. Varför detta kan vara negativt för hjortar är för att det är viktigt att de har god kunskap om området de vistas i då det gör det möjligt för dem att hitta bra föda samt skydd vid faror. Detta har de i sina normala hemområden och om de tvingas lämna dessa kan det leda till negativa konsekvenser. I detta arbete, som genomfördes genom ett samarbete med Grimsö forskningsstation, Sveriges lantbruksuniversitet, undersöktes huruvida dovhinden (Dama dama) påverkas av jakt.

Rådjur (Capreolus Capreolus) på Gotland : populationsutveckling och spridningsmönster

Gotland is an island in the Baltic Sea where man has introduced roe deer. The last successful reintroduction was in the 1980s and is the base of the viable roe deer population of today.The aim of this study was to estimate the roe deer population density in 2012 and the species population dynamic since the time when studies on the population started. The result indicates a population size of 850 roe deer in 2012. There was no significant population dynamic, which may be due to insufficient data. The population occurs basically over the whole island but have not yet been established in all suitable areas.

Ledande roller och beteenden i hindgruppen (Dama dama & Cervus elaphus) ur ett etologiskt perspektiv

Rollen som ledare hos grupplevande djur har ifrågasatts inom den vetenskapliga litteraturen. Kronhjort och dovhjort är de två grupplevande arterna av hjortvilt som lever i Sverige. Större delar av året lever de i könsseparerade, matriarkala familjeflockar som enligt lekmannen sägs domineras av en ledarhind. I denna litteraturstudie har rollen som ledare i en flock analyserats ur ett etologiskt perspektiv. Vetenskaplig och populärvetenskaplig litteratur har jämförts med fokus på sociala beteenden hos framförallt ungulater (hovdjuren), dit bägge dessa arter hör.

Större och mindre växtätares samexistens : Möjlig interaktion och effekt på lokal biodiversitet

The purpose of this report was to investigate to which extent local presence of large herbivore mammals (Alces alces, Cervus elaphus, Capreolus capreolus, Dama dama and Sus scrofa) covaries with small rodents (Myodes glaerolus, Apodemus flavicollis and Apodemus sylvaticus? The hypothesis was that high abundance of wild ungulates would inhibit the density of small forest rodents. The data was collected during field work within FoMA (Environmental Monitoring Assessment)/SLU (Swedish University of Agricultural Science). The Ungulate dropping inventory and rodent trappings, which is the base in this report, where performed 2012 ? 2014 in Gnesta/Nyköping municipalities (G/N) with a relatively high density of wild ungulates and Vetlanda/Växjö municipalities (V/V) with relatively lower wild ungulate density.

En studie av viltets påverkan på Skogssällskapets fastighet i Selesjö

This degree project investigates how elk, roe deer, red deer and fallow deer can affect an estate in Östergötland. The inventories performed within this project, were completed on an estate in Selesjö, northern Östergötland. This property is used to demonstrate wildlife management. The methods used in this study were originally developed for areas larger than individual properties. Three inventories were completed in the study. These included the recording of the number of droppings and the amount of eaten pasturage, as well as the level of damage on young trees.

Spader dam. Ofrånkomliga pragmatiska skillnader mellan källtext och måltext vid översättning av rysk skönlitteratur

Denna uppsats behandlar skillnader mellan skönlitterär käll- och måltext utifrån enegen översättning av Ljudmila Ulickajas ?Pikovaja dama? från ryska till svenska.Målet med översättningen var att skapa en publicerbar översättning som låg så näraoriginalet som möjligt utan att bryta mot för målspråket gällande grammatiska ochsyntaktiska regler. Målet med uppsatsen var att utifrån översättningsvetenskapenförklara vilka skillnader som uppstår vid översättning av rysk skönlitteratur tillsvenska. I uppsatsen försöker jag även undersöka varför dessa skillnader uppstår ochvilken betydelse de har för måltexten. Frågan vad en översättning egentligen är aktualiseras..

Jämförelse mellan viltbehandlade och obehandlade granplantor : Med inriktning på höjdtillväxt och betesfrekvens

The report is a comparative study between spruce plantations where 4 plants are treated with deer repellents and 4 plantations are untreated. The study aims to provide a base for the Forest Society's future decisions regarding the use of wildlife-repellents.  The report indicates that wildlife-repellents work reasonably well for its purpose, the treated stocks were virtually untouched during the planting year and next year while the untreated stocks have been heavily grazed during these years.  Growth difference between grazed plants and ungrazed plants found to be virtually non-existent (0, 01 m) of the treated stocks and 0, 07 m in the untreated plants. Because of the growth differences are so small between grazed and no grazed plants, it seems like the treatment of deer-repellent are unnecessary. Unless you know in particularly that the area has a specific problem whit severe deer-grazing..

Mångbruksplan inriktning vilt och viltvårdsanpassning av skogen

This multiple use forestry plan is made on the property Basunda which is located in the southern parts of the province Östergötland. The owners of the property today are Jonas and Ulrik Saanum, but it has been in the family since their grandfather bought it 1933. There is a slaughterhouse on the property in which they take care of domestic cattle and animals from the forest. Jonas and Ulrik are also dedicated hunters. These are the two reasons to why the focus is wildlife and wildlife management. The question at issue of this work is simplified: what demands does the wildlife have; and how will the owners be able to fulfill these, what changes in the forest management must be made and will these changes result in a different budget, compared to the ordinary forest management. This work is based from a freshly made forestry management plan. I based my fieldwork on this plan, but made my own management proposals, that would benefit the game.

Does tree removal along railroads in Sweden influence the risk of train accidents with moose and roe deer?

After the storm Gudrun in 2005, the Swedish Transport Administration started clear-cutting of railroad corridors to reduce the risk of trees falling down on the tracks. Simultaneously, train accidents with moose and roe deer have become more frequent and the costs for consequent delays and repairs of engines are of growing concern. There is reason to assume that tree-clearance of railroad corridors may have contributed to an increase in number of accidents with moose and roe deer because the cleared areas provide attractive forage and thus may attract wildlife. The objective of my study was to investigate how clearing of trees affected the number of accidents with moose and roe deer. I compared deer-train collision frequencies before and after clearance of the selected railroads and compared these with uncleared control railroads in a BACI (before-after control-impact) approach.

Tick burden in neonatal roe deer (Capreolus capreolus): the role of age, weight, hind foot length, and vegetation and habitat on bed sites

This thesis deal with tick burden on roe deer (Capreolus capreolus) fawns, in relation to age, weight, hind foot length, and as well as to vegetation and habitat on bed sites. Roe deer fawns (N = 25) were captured from May 27 to June 27. Samples of ticks were collected and tick burden were estimated. Of all sampled ticks the nymphs and adults were Ixodes ricinus, while the larvae were not identified. 4.4 % of the sampled ticks were larvae, 55.0 % nymphs, 26.8 % adult females, and 13.8 % adult males.
