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.

Comparison of bird communities in stands of introduced lodgepole pine and native Scots pine in Sweden

The introduced lodgepole pine (Pinus contorta) occupies more than 650 000 hectares in Sweden. There are some differences between lodgepole pine and Scots pine (Pinus sylvestris) forests which could affect bird assemblages, for example differences in canopy density and ground vegetation. Birds were surveyed in 14 localities in northern Sweden, each characterized by one middle-aged stand of lodgepole pine next to a stand of Scots pine. The two paired stands in each locality were planted by the forestry company SCA at the same time and in similar environment to evaluate the potential of lodgepole pine in Sweden. In those 14 localities, one to three point count stations were established in both the lodgepole pine and the Scots pine stand, depending on the size of the area.

F?gelv?gen och f?gels?gen. En multi-proxy analys av m?nniskans relation till f?glar under den yngre j?rn?ldern i Mellansverige

Prior research in human bird relations is relatively small and discussion about bird ecology in relation to humans is largely not discussed. The study means to understand how a difference in usage of birds and symbolization of a bird occurs. This will be answered through analysis of two bird species. The study uses three different sources of material to conclude its answers. The sources are graves with bones of predatory birds, material culture representing bird motifs and historical sources discussing mythology.

Zoonotic respiratory infections and great ape conservation - an emerging challenge

The conservation of great apes faces many challenges, one of which is the threat of infectious disease outbreaks. Zoonotic transmission of respiratory diseases from humans to wild great apes has recently been confirmed. Since respiratory disease is one of the major causes of death in both gorillas and chimpanzees, this gives reason for major concern. Little is known about the risks of disease transmission from humans to great apes in natural environments, and there is a need for systematic risk evaluation. Researchers, conservation staff and tourists spend time in very close proximity of wild great apes, sometimes during long time periods, which poses a potential risk of disease spillover. However, the presence of researchers and tourists has been shown to decrease the risk of poaching, making the matter increasingly complex.

Biologisk mångfald i små grönområden : Inventering av insekter och fåglar i bebyggda områden i Solna kommun

All over the world the urbanisation increases at the expense of green areas. Many plants and animals are endangered today because their habitats gets smaller or disappear. The green areas that are left in city centres and suburbs are often small and surrounded by roads and buildings. Despite this, several studies have shown that these small green areas may house large biological diversity.This project aims to study the biological diversity in small green patches in residential areas. The study has been carried out in Råsunda in Solna municipality (Stockholm county) during the period May?July 2006.Three equivalent areas (5000?10 000 m2) with quite many old oaks were chosen for the study and inventoried for birds and saproxylic insects.

Kombinationsbruk, talltimmer och vilt?

When I began my studies at Gammelkroppa forest school I started to think about an appropriate thesis. There was much discussion about the wild grazing damage during that period. I was at that time a part of Boo property and helped at their great hunts. They had the dual uses of wildlife and forest. I decided that I want to study how big the wild grazing damages are and if we can reduce them.

Echinococcus multilocularis in wild boar : aiming at an alternative surveillance method

This study was the first part of a larger project investigating a new surveillance method for Echinococcus multilocularis. In this study we examined livers from wild boar (Sus scrofa), looking for lesions caused by E. multilocularis. E. multilocularis is a small tapeworm which has an indirect life cycle.

Balis trädgårdar

The urbanization of the world is increasing. How it affects bird populations have been well studied during the last decade, and comparisons between urban and non-urban habitats have been carried out. A common method for measuring habitat quality is to calculate the population density. This method is easy to use, but have been criticized during the last couple of years. In this study, data of population densities was compared with data on reproduction success.

Begomovirus susceptibility in wild Nicaraguan tomato populations

Tomato production is a common and important agricultural activity in Nicaragua. During the last decades tomato producers have suffered great yield losses due to begomoviruses (family Geminiviridae). The genome of begomoviruses generally consists of two circular ssDNA components, DNA-A and DNA-B. Tomato yellow leaf curl virus (TYLCV) is an example of a begomovirus with only one component. An approach to manage the virus epidemics has been to breed a cultivar with begomovirus resistance genes, which have been transferred from wild tomato.

En studie av Fish-Bird?s navigeringssystem

Fish-Bird är ett pågående vetenskapligt/konstnärligt projekt som genomförs i samarbetemellan konstnären Mari Veloni och Australien Center for Field Robotics. I korthet bestårprojekt av två robotar i form av rullstolar som interagerar med varandra och sinomgivning. Robotarna heter Fish respektive Bird och därav projektnamnet Fish-Bird.Detta examensarbete utvärderar Fish-Birds navigeringssystem. Bakgrunden tillutvärderingen är en oklarhet i huruvida navigeringssystem är ofullständigt eller felaktigt.Navigeringssystemet har visat bristande funktionalitet vid upprepade tillfällen. En stordel av problematiken förekommer oftast när hinder befinner sig nära varandra.Studien är gjord genom en detaljerad analys av Fish-Birds navigeringssystem.

FORL : Feline Odontoclastic Resorptive Lesions

This report was written in an attempt to summarize old and new theories and scientific results regarding FORL (Feline Odontoclastic Resorptive Lesions). Several different kinds of treatment are presented in this study. Among them teeth extraction and crown amputation seems to give the best long-term results. It seems clear that the domestic cat of today have no trouble digesting dry foods without their teeth. The most accurate way to diagnose FORL is by using intraoral dental radiology technique.

Omvårdnad vid blodprovstagning och venpunktion på fåglar

Blood sampling is one of the most important diagnostic tools in veterinary medicine, and this is also true for avian medicine. A properly collected and handled venous sample can be used for serology, biochemistry and electrolyte analysis, as well as for blood smears, packed cell volume and cell differentiation. Caring for sick birds is a challenge for all veterinary staff. Many birds are easily stressed individuals, and to a very ill bird a big increase in stress level can even be fatal. Avian patients who are presented in a veterinary clinic are often in a poor condition, and blood sampling is an invasive procedure that can cause stress to the patient.

Den ömma vilden : -En studie av pedagogens syn på den fysiska kontakten mellan barnen i den vilda leken i förskolan

The Purpose of this study is to contribute knowledge on and to make the preschool teachers views visible about physical contact between children in wild play in the preschool. I decide to use interview of preschool teachers in a group setting as a mean to investigate this. The group interview is a non-structured interview with open questions where the preschool teachers only received guidance with pre made questions when needed.The result shows what kind of view the preschool teachers have on physical contact and they share concreate examples on how they work in situations like these.By reading this study I hope to contribute better knowledge of the physical contract between children and that the study generates futher reflections on one´s attitude in the matter..

Parasitologisk undersökning av parasiter hos tjäder, (Tetrao urogallus) :

In the report parasites in the gastrointestinal tract and easily visible external symptoms of disease in capercaillie, (Tetrao urogallus), was taken into account. The study was based on results from the examination of 62 fresh faecal samples, collected in spring 2003, and postmortem examination of 22 frozen birds that were collected between 1999 and 2003. All of the samples principally were from the north of Sweden. In total, 4 species of parasites, but no significant symptoms of disease were found. In the faeces low levels eggs of the roundworms Capillaria spp. (125 epg) and Ascaridia spp.
