The life cycle of the anadromous Atlantic salmon (Salmo salar) can span large geographic, political, and socio-economic boundaries. Management strategies and regulations that only concentrate on small spatial scales often overlook larger basin-wide problems, especially relating to post-spawn seaward migration. In this master thesis one entire migration cycle of Wild adult Atlantic salmon in the unregulated northern Swedish river Vindelälven was monitored by radio-telemetry tracking during upstream spawning migration and downstream seaward migration back to the Baltic Sea. The effect of ladder passage variables (time to pass, total time in the ladder, passage day over the ladder) at a fish ladder downstream in the river Umeälven, as well as fish size, were evaluated to determine if differences in upstream migration distance in the river Vindelälven could be observed. Ladder passage variables did not affect migration distance, but size exhibited a negative relationship to migration distance.

Wildlife is a valuable and renewable resource that promotes economical, ecological and social values. These values are important for developing and maintaining many rural societies. However, growing ungulate populations have led to increased browsing pressure on valuable forest trees and crops. Previous studies have proposed supplementary feeding and gamefields as potential methods for controlling the ungulate foraging and reducing browsing damage by providing other attractive food resources. However, quantitative estimates of potential biomass production of various gamefield crops and browsing pressure on the surrounding forest have been lacking.

Horse owner?s knowledge about horse feeding and nutrition is directly linked to the horse?s health and welfare. According to several studies, both Swedish and foreign, horse owners generally have inadequate knowledge about horse feeding. The housing systems and feeding routines of today differs in many ways from what horses have adapted to through evolution. Wild horses live in harem herds and roam on large open fields, spending about 60 % of the day grazing, mainly grass and herbs.

Under åren 1985 till 2005 har Gävle kommun kontrollmätt ett antal byggnaders grunder inom centrala Gävle med finavvägning. Syftet med dessa mätningar var att kontrollera eventuella sättningar och övervaka hur dessa utvecklades. Nu, 2011, upprepas några av mätningarna i detta examensarbete och syftet är att jämföra dem med kommunens tidigare mätningar. Examensarbetet resulterar även i att rutiner och metoder för fortsatta mätningar dokumenterades, punktskisser för de avvägda dubbarna upprättades och deras position lades i ett eget GIS-lager.Vid insamlandet av ny mätdata användes instrumentet Leica Wild NA3000 med invarstänger. Områdena (Berggrenska gården, Södra strandgatan och Norra skolan), avvägdes i slingor runt objekten som återanslöts till samma punkt.

ABSTRACT. In the late 1960?s all the wolves in Scandinavia went extinct in the Wild due to extensive hunting. In 1983 two new wolves immigrated and founded, together with a third immigrant in 1991, the population that exists today. Due to the fact that the population originates from less than a handful of individuals, the genetic variation is small.

Toxoplasma gondii är en intracellulär, zoonotisk parasit med förmågan att infektera i stort sett alla varmblodiga vertebrater, medan endast kattdjur kan fungera som huvudvärd. Parasiten finns spridd hos människor och djur över hela världen. Vid symptomatisk infektion med T. gondii ses en varierande klinisk bild. Kongenitalt överförd smitta leder potentiellt till abort eller neonatal infektion.

Afrikansk svinpest är en av de allvarligaste grissjukdomarna och är på frammarsch i östra Europa. Under 2000-talet har det oerhört tåliga afrikanska svinpestviruset med hög morbiditet och mortalitet spridits från Afrika till Kaukasusregionen och angränsande europeiska länder där den utgör en stor risk för den globala grisindustrin. Sjukdomen är ingen zoonos men eftersom det saknas vaccin och behandling har den en stark påverkan på människor rent socialt och ekonomiskt när deras grisar drabbas. Sjukdomsutbrott leder till minskad internationell handel, kostsamma kontrollstrategier för att stoppa utbrott och stora förluster för småskaliga bönder. Syftet med denna litteraturstudie är att utvärdera huruvida europeiska vildsvin kan bli ett hot mot grisproduktionen i Sverige.

The aim with this thesis was to investigate what characterises an English Arts and Crafts garden how they could be modernised in Sweden. My research was limited to 20 weeks of full-time writing and worth 30 ECTS. Through literature studies, interviews and site visits I could analyse my findings which resulted in a concrete garden design project. The Arts and Crafts was a movement that started in England during the 1880?s and evolved as a reaction towards the industrialisation. The influence came from the writings and practices of John Ruskin (1819-1900) and William Morris (1834-1896) who advocated the importance of craftsmanship. The Arts and Crafts movement also became a ?recipe for life? and was associated with a healthy and morally pure way of living.

An introduction to the complexity which surrounds the matters of land in the northern parts of Sweden was the purpose of this thesis. The agriculture colonization, the delimitation and the development of forestry and mining business were big events which are shown from the view of property rights. The situation of the Lappish people and how their situation has changed through the history was the main theme of the thesis. Hopefully this thesis will also serve as a support while reading for example investigations published by the government and judgments by courts. Supply to the resources of nature has always been decisive for the survival of humans.
