Suitability analysis of a reintroduction of the great bustard (Otis tarda) to Sweden
The great bustard (Otis tarda) became extinct in Sweden during the mid-19th century. Globally, populations have suffered dramatic declines during the past two centuries. Recently, local populations have stabilized or increased after hunting bans and conservation efforts. Despite positive trends the species is still classified by IUCN as vulnerable (VU), mainly due to withdrawals in the distribution. The limited distribution emphasizes the need for finding ?new? areas suitable for a translocation or reintroduction.
Kan markfuktighetskartor användas för att hitta skogsmark med hög bonitet? : ett gis-baserat försök med dtw-index och laserskannad övre höjd
The depth-to-water-index (DTW-index) is derived from digital elevation models (DEM) to map soil wetness, in terms of distance from soil surface to the ground water table. The aim of this GIS based study was to investigate the existence of a relationship between DTW-index and forest site productivity (SP). The belief of such an assumed relationship was based on knowledge that the ground water level is related to site properties that can either promote or impede tree growth.
Data primarily comprised rasters of the Krycklan catchment in northern Sweden and depicted DTW-index and a laser scanned vegetation height. The 100th height percentile of each pixel in the vegetation raster was assumed to mirror the top-height, letting it act as a relative measure of SP within a delineated area of equal stand age.
Vattensänkningar : en analys av orsaker och effekter
There are records of lowering of the water level in a lot of the Swedish lakes from the middleof the 1700th century. The aim was gaining more areable land to meet the needs of more foodto support the expanding population. In areas with top soil which contents of clay or loam asin the southwest of Scania in southern Sweden this was proven to be a successful wayexpanding the total outcome of the harvest.The studied area in the northeast of Scania, though, consists of morain with a lot of mires -much less nutritious conditions. When the water level is lowered the atmosphere gets accessto the peat. The dissolving of the organic matter that has been suppressed by the lack ofoxygene below water level continues.
Grundvattensänkning till följd av järnvägstunnel genom Hallandsås : miljökonsekvenser relaterade till förändrad kväveomsättning i mark
This thesis was carried out to give some background information to a report of SLU (Swedish University of Agricultural Sciences) for the Swedish National Rail Administration (Banverket). The requested information was to provide basic data for an environmental impact assessment of the construction of the tunnel through Hallandsås. The aim with the thesis work was to discuss and quantify the leaching of nitrate and the emission of nitrous oxide from the soil at the groundwater level established through the tunnel project. The nitrogen related processes that could be affected were described and discussed. The different areas where a decreased groundwater level can cause changes in the nitrogen processes are the wet and moist areas.
"alla är vi lika i samma båt" : Språkbadpersonal berättar
In September of year 2006, a young boy was brutally killed by a girl, age sixteen, in Örebro, Sweden. Girlgangs became a frequent subject in media. Professionals? working with adolescents claims that girlgangs notis an existing phenomena in Sweden as it is in for example in the United States. The aim of this thesis was to investigate if teenage girls in Sweden have a tendency to join gangs as they do in the United States.
Generell hänsyn vid avverkning : påverkan av dispens från sexveckorsregeln samt skogsägares kunskap, tankar och åsikter
The forests in Sweden have, for a long time, been managed intensively. This has led to even-aged stands with few tree species and a lack of dead wood. Therefore, general conservation measures in connection with regeneration felling are important in order to promote biodiversity. Inventories carried out by the Swedish Forest Agency, however, show that about 25 % of the felled area does not reach the level of the Forestry Act, regarding general conservation measures. The aim of my study was to see whether exemptions from the six week notice of reporting regeneration fellings (the Forest Agency demands a report six weeks in advance of fellings), affect the results of the general conservation measures taken.
Potentiella arealer för ökad virkesproduktion i norra Sverige genom skogsodling med Pinus contorta var. latifolia, Larix sukaczewii, Abies lasiocarpa, Populus × wettsteinii och Picea mariana
Sweden is a country with few native tree species. According to Govt. 2007/08: 108, exotic tree species may be seen as an opportunity to increase the growth of tree volume in Sweden. Potential areas where explored In this work for cultivation with Pinus contorta var. latifolia Engelm., Larix sukaczewii Dylis, Abies lasiocarpa (Hook.) Nutt., Populus × wettsteinii Hämet-Ahti (tremula x tremuloides) and Picea mariana (Mill.) Britton et.al.

Bild : Kommunikation och uttryck
The aim of this study was to search for a link between the subject pictorial studies in means of expression and the ability to communicate in written and spoken language. To do so findings in relevant literature and a few complementing theories was addressed to cast light on interviews made with teachers dedicated to the subject pictorial studies in a subject-integrated curriculum.Interviews were conducted with nine teachers and all but one were teachers in the subject pictorial studies, spread across all of the nine grades in compulsory school. Informants were located in areas of socioeconomically high as well as low status, in central and densely populated areas as well as areas less densely populated. The diverse theoretical background consisted of semiotics, constructivist theory, social constructivist theory and genre theory. Theories and literature partly both contradicted and supported each other, depending on situation and circumstance.No evident conclusion could be made that discriminated one affecting cause from another on speech or writing skills.
Finansiering av företag : är bristen på externt kapital en faktor som hämmarlandsbygdsföretagens tillväxt?
The interest in businesses active on the countryside and their funding situation has increased in recent years. In a survey, conducted by Leif Berndtsson (2003), it was reported that there is a lack of external capital in rural areas. According to Berndtsson (2003) the lack of external capital inhibits the rural firm?s growth. The essay attempts to answer whether the shortage of external capital is a factor that inhibits development for rural businesses.
Effekt av ras och säsong på nötkreaturs avbetningsgrad av konkurrenskraftiga betesmarksväxter :
Grasslands which have been actively managed for a long time and which in modern times have not been subject to cultivation such as fertilization are called semi-natural grasslands. These rare and species-rich areas hold an ecological, biological and historical value and if the management stops these areas will likely diminish. More effective agricultural systems and a declining number of grazing animals have in Sweden, among other countries, made semi-natural grasslands less valuable as foraging areas. Shrubs and fast growing plants rapidly colonize abandoned semi-natural grasslands, threatening biodiversity.
The objective of this experiment was to determine the effects of breed and season on diet composition, with special reference to four competitive species found in wet areas ? in cattle grazing heterogeneous semi-natural grasslands ? and thereby contribute to improved management of these areas.

Wolf movement patterns and the distribution of moose kills : implications for human harvest?
Most studies regarding wolf (Canis lupus) predation on moose (Alces alces) have focused on the total annual consumption of moose within a wolf territory but few have tried to describe the spatial impact of wolf predation on a local scale. In this study I have analyzed wolf movement data, wolf predation, moose hunting statistics and moose hunter observations to investigate how wolf predation affects the human harvest of moose in Scandinavia. Since wolves prey on mostly juvenile moose during summer, analysis of their summer movement patterns is crucial to understand its impact on the human harvest later during autumn. In this study both reproducing (n = 45) and non-reproducing wolves (n = 12) reduced their movement range during summer to 66% and 67% of their annual movement range, respectively. Reproducing wolves increased their movement range from early to late summer while non reproducing wolves did not.
Etanolmarknaden i Brasilien : etanol som fordonsbränsle
According to the EC fuel regulations 2 % bio fuel has to be blended in all fuel by the year 2005, and 5.75 % by the year 2010, which means ethanol for gasoline driven vehicles, so there will be a substantial demand for ethanol. Brazil already has an established industry for producing ethanol and is the leading producer and exporter of fuel ethanol. My purpose with this paper is to investigate why Brazil decided to develop ethanol production on a large-scale operation and to find out today?s situation. Focus will mainly be on ethanol production with sugarcane as a feedstock.
Landsbygdsföretagerskan : en fallstudie om den kvinnliga företagarens livsform på landsbygden
This study is about the female entrepreneur in rural areas in Sweden. Five women were interviewed with the aim to examine their way of living (livsform), their motivation, what significance it is to be a woman in business and how female entrepreneurs can be encouraged to start their own business.
The conclusions :
? The women in this study live an independent life , but the their way of life (livsform) has changed during their life
? Female entrepreneurship can be promoted trough greater knowledge of the female business, better advice to the entrepreneurs, more networking groups and reducing bureaucracy.
? The driving forces for the women is to do what they like and are interested in, at the same time as they have time for the family and children. They also like to work in the rural areas.
? Female entrepreneurship can be promoted through greater knowledge of female businesses in the community, by creating virtual meeting places such as networking groups and mentor groups on internet.
