The plants in the genus Elatine are characteristic for oligo and mesotrophic lakes. This study focuses on Elatine hexandra one of the four species in Sweden. It is stated as vulnerable by the National Environment Agency and a conservation plan with guidelines to preserve the plant in Sweden is under preparation. There have been a few previous studies investigating this plant in other countries but this is the first one for Sweden. The aim of this study was to investigate the distribution, growth and reproduction of E.

Unauthorized changes in listed buildings and environments occur all around Sweden. The main purpose of this thesis is to examine how these forms of transgressions have been and are being handled in some Swedish county administrations. What do legislation within conservation of heritage expresses when transgressions occur? How do county administrations interpret and apply legislation to actual situations? What methods do county administrations make use of to prevent unauthorized changes?16 out of Sweden´s 21 county administrations have been studied and used as an empirical basis. This basis has led to a general conclusion of the county administrations experiences and working processes when handling unauthorized changes in listed buildings.

AbstractThe church of Borrie lies about 10 km north of Ystad in the southern of Sweden. Though thechurch is one of the smallest in Scania it holds a very complicated history.In this essay all relevent material concerning the church of Borrie is presented. The materialdoes not only concist of literature, but also photographs. The purpose of this investigationwas to use this material to sort out and explain the history of the church of Borrie.The problem is presented in the following points:1. Is it possible to do a building archaeological analysis with photographs of the churchas the main material?2.

The European bison is a species which is no longer present in the wild fauna of Sweden. Reintroduction has been proposed in several different forums. Reintroduction is an attempt to reestablish a viable population of a species in an area to which it is native. To make such an operation successful in the long run it is essential to know the attitudes of the stakeholders involved. This study has sensed the attitudes towards reintroduction of European bison to Sweden.

This essay deals with the weak and unstable urbanization process of the town Falkenberg. The aim has been to explore how a new town could be established just a kilometre away from the town (Old) Falkenberg and what kind of meaning the town had in relationship to the towns Halmstad and Varberg. This was made through the study of the political situation in Denmark and Sweden during the 15th century and through a comparison of the town churches. The archaeological material of Falkenberg is very small and thus I had to trust the available historical literature about the town.Not much of the oldest history of the town is known, but a conflict between the landed aristocratic family Thott and the king Kristian I in Denmark has been interpreted as a reason to the establishing of the town. In conclusion the survey showed that the king probably established New Falkenberg in purpose to limit the trading possibilities of Thott and to, at the same time, increase his own power in the district.

Semi-natural grasslands are threatened biotopes in the landscape and without conservation measures high values of nature will be lost. Meanwhile, the biological values associated with cultural values of the traditional agricultural landscape in Sweden. Studies of land use history may help to understand how today biological diversity has evolved and how it can be preserved. Färsna farm in Norrtälje has left some of the old heritage of biological diversity in the form of nature - forest and grassland, which hosts an unusual herb-rich flora. Through the study of historic maps and från1673/1767/1801/1901 1952 and orthophoto of the area has a picture of how land use has changed over time emerged.

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.

This essay aims to explore continuity in water centric cult within the period of the Christianization of Scandinavia (ca 800-1100 AD) and to understand the changing of symbolism of water in pre-Christian cult and early Christian religion. It has previously been thought that Christian priests took over the old holy wells and renamed them after saint, all to ease the pagan people into a Christian lifestyle. But archaeological evidence shows that the cult at these wells, and other water centric sites, where almost completely abandoned a few hundred years before the Christians came to Scandinavia. The Christians should not have felt the need to transform this tradition since it was only practiced in a very small and supposedly private scale. On the contrary, religious activities at these wells seems to increase with the new religion and perhaps this is explained by Christianity itself.

The use of forage maize has increased over the last years. The aim of this litterateur review was to summarize a part of the research that has been conducted on forage maize for growing cattle, including cultivation and conservation of the maize. The forage maize is planted in April or the beginning of May when the temperature in the soil is between 6 and 10°C. Maize needs high temperatures and much water. Maize is harvested in the autumn when the dry matter (DM) is more then 30% or the plants have been exposed to the first frost in the autumn.

Human presence has always influenced the surrounding areas, the forest as well. Structure and species composition have changed during human land use. Knowledge regarding these changes should be of great interest for conservation and forestry. We have analyzed human impact on the tree species composition on five study sites during 2000 years in Ångermanland, Sweden. More specifically the change in tree species composition in percentage amongst alder, birch, spruce and pine over time.

Thid thesis concerns pre-Roman religion in Gaul, taking as its starting point Caesar's De bello Gallico. Caesar's account of the Gauls and their religious customs is compared with the accounts of Lucan, Pliny the elder and Ammianus Marcellinus. These are also compared to, and contrasted to, the archaeological evidence. There is some discussion of the nature of the common interpretations of this evidence. The concept of 'the Celts' is touched upon, since much of the relevant evidence has, in our time, been thought of as Celtic.

Burnt Spine-cap Sárcodon fuligíneovioláceus are one the most endangered mycorrhizal fungal species in Europe. They have their main distribution in Sweden. It form mycorrhiza with pine and dependent on limestone, which makes it connected to a rare environment. It has therefore been important to study the ecology of it further and to recognise the requirement it has on the environment more accurate and what it need to establish in a new area. In this study, 31 of 34 known sites in Sweden was visited and studied in field and their history analysed through aerial photographs.

With rising energy prices and the threat of climate change, energy costs and energy savings havebecome a central and important part in building. Therefore it is interesting to explore different andnon-conventional methods of energy conservation. Building Earth sheltered houses is such a method.Earth provides good insulation and provides the ability to both reduce the total heating needs and toreduce the maximum power demand. The aim of this study was to construct a house in Malmö and seeif Earth sheltered houses can be a cost effective alternative for the construction of sustainable andenergy-efficient houses.Previous studies have shown that Earth sheltered houses have reduced their power requirement with upto 25% and their use of energy with 10%. Numerical calculations in Comsol Multiphysic 4.2, wasperformed on a house with different degrees of earth covering.

The global biodiversity loss is mainly due to human activities such as an intensification of forestry. Boreal forest ecosystems in Fennoscandia are characterized by disturbances such as forest fires, storms and floods. However, industrial forestry practices suppress forest fires and change the landscape, leading to a loss of habitats and associated species. Particularly lichen species with slow adaptation abilities and a strong substrate specificity face an extinction debt in boreal forests since their substrates are long-lived but no longer created. In this study the species-substrate relationship of two red-listed forest-fire dependent lichen species Carbon-icola anthracophila and C.

Kunskapen kring svensk torvmarksbeskogning är undermålig. En kunskapslucka som till stor del beror på att torvmark tidigare bedömts som ointressant mark i samband med skogsproduktion. Detta beror mycket på det svenska regelverkets restriktioner mot markavvattning och gödsling samt miljöaspekterna som berörs och den aktivare skötsel som krävs. Det ökade behovet av skogsråvara gör att skogsbruket söker nya marker där torvmarken har potential att etableras för skogsproduktion.Studien är en kunskapssammanställning som lyfter fram kunskap kring skogsbruk på svensk torvmark med fokus på föryngringsprocessen. Finland använder torvmarker i skogsbruket på ett sofistikerat sätt.
