1	Det var en gång en grotta : Om hästarna från Stora Förvar / There once was a cave : Concerning the horses of Stora Förvar Brozén, Astrid January 2020 (has links) Humanity has long lived alongside a variety of animals. We have eaten their flesh, utilized their bones for tools and trinkets and learned to care for and appreciate them. When animal remains are ignored or left out in archaeological research, a large part of our common history is left untold. This is especially true in the case of the cave Stora Förvar on Stora Karlsö outside the west coast of Gotland. The cave was first excavated in 1888–1893 by Lars Kolmodin and Hjalmar Stolpe. Their excavations left behind a little more than two metric tonnes of animal bones of various species which since then have not been thoroughly analysed. The equine remains have barely been touched at all. The purpose of this essay is therefore to create an overview of the horse population from inside the cave and determine in what manner they were used by the humans. In order to do so the author will utilise a microarchaeological approach along with ritual theory. Through an osteological analysis combined with literary studies the equine remains and their uses are discussed. Hopefully, this work will add another piece to the puzzle that is Stora Förvar.

2	Det var en gång en trädgård : Om odlande vid Stora Karlsö fyrplats / Once there was a garden : Conserning cultivation at the lighthouse of Stora Karlsö Lindblom, Emmy January 2018 (has links) Ön Stora Karlsö, belägen ca 15 km väster om Klintehamn, Gotland, har sedan länge varit skyddad för sina höga naturvärden. På ön finns en fyrplats från 1887 vars bebyggelse är statliga byggnadsminnen. Söder om fyrplatsen finns en gammal igenvuxen fyrträdgård vilken utgör föremål för fallstudie i detta arbete. Karlsö Jagt- och Djurskyddsförening AB äger majoriteten av all mark på ön och förvaltar den, samt bedriver besöksverksamhet. De har en önskan om att eventuellt åter kunna bruka mark i fyrträdgården för småskalig odling av köksväxter. Syftet med arbetet är att genom dokumentation, insamlande av kunskap och information om fyrträdgården på Stora Karlsö bidra till att dess kulturhistoriska värden inte går förlorade vid eventuella nyodlingar i trädgården. Syftet är även att öka kunskapen om fyrträdgårdar och dess betydelse och funktion i Sverige i allmänhet, samt att därigenom synliggöra det gröna kulturarvet i äldre tiders trädgårdsodling. Resultaten visar att trädgården, som var i ständig förändring under tiden den brukades, var hierarkiskt uppdelad mellan de anställda vid fyrplatsen och odlingsytan var indelad i inhägnade lotter. Trädgården har både haft en funktion för självförsörjning och kontemplation och både köksväxter och prydnadsväxter har odlats. Idag finns t. ex. syrener, gullregn, bondpioner samt nio olika äldre sorter av narcisser kvar i trädgården. Avläsbara strukturer i marken samt gjutna fundament för staketstolpar visar var tidigare odlingslotter har funnits. Väldisponerade och genomtänkta nyodlingar i trädgården skulle inte skada dess kulturhistoriska värden, utan snarare bidra till förståelsen av platsens historia och vara positivt ur ett bevarandeperspektiv. / The island of Stora Karlsö, located about 15 km west of Klintehamn, Gotland, has long been protected for its high natural values. There’s a lighthouse from 1887 on the island and buildings connected to it are state monuments. South of the lighthouse there’s an overgrown garden from the lighthouse period which is the subject of study in this essay. Karlsö Jagt- och Djurskyddsförening AB owns the majority of all land on the island and manages it, as well as conducting visiting activities. They have the desire to resume small-scale cultivation of vegetables in the lighthouse garden.The aim of this studie is to, through documentation, gathering of knowledge and information about the lighthouse garden at Stora Karlsö, ensure that its cultural and historical values are not lost in the event of any new cultivation in the garden. The aim is also to increase the knowledge about lighthouse gardens and its importance and function in Sweden in general, and thereby make the green heritage in gardeing of elder times more visible. The results show that the garden, which was in constant change while used, was hierarchically divided between the employees at the lighthouse and the cultivation area was divided into fenced allottments. The garden has both had a function of self-sufficiency and contemplation, and both vegetable plants and ornamental plants have been cultivated. Today there are e. g. lilacs, common laburnum, peony and nine different older varieties of narcissus left in the garden. Structures in the field as well as foundations for fence posts show where previous allotments have been located. If carefully implemented, new cultures in the garden would not damage the cultural and historical value of the garden, but rather contribute to the understanding of the history of the site and be positive from a preservation and maintenance perspective.

3	On the origin of the mountain hare on the island of Gotland : By means of ancient DNA analysis Ahlgren, Hans January 2011 (has links) The island of Gotland houses a number of terrestrial mammalian species even though it was covered with ice during the last glacial period. The purpose of this study is to genetically analyse the mountain hare (Lepus timidus) to deduce its origin and genetic structure during different time periods, and also to discuss how it reached the island. A 130 base pair sequence of mitochondrial DNA from 38 prehistoric hares was analysed and compared to modern hares from different locations in Europe. The result shows a discrepancy among the samples creating two populations with different origin. aDNA Lepus timidus Gotland Stora Karlsö mtDNA migration phylogeography Archaeology subjects Arkeologiämnen
4	Värmereglering i Östersjöns största sillgrisslepopulation : En studie av värmereglering hos sillgrisslor på Stora Karlsö, juni 2019 / Thermoregulation in Common Guillemot : A Study of Thermoregulatory Behavior of the Common Guillemots in the Baltic Sea’s Largest Colony on Stora Karlsö, June 2019 Karlsson, Erika January 2020 (has links) Previous studies have shown how endothermic organisms have a range of environmental temperatures in which energy used for thermoregulation is relatively low. If the temperature exceeds this specific range, the individual needs to thermoregulate. The demand for thermoregulation depends on several factors, for instance the intensity of solar radiation. Species which have little opportunity to avoid incident solar radiation at their breeding sites, such as cliff-nesting seabirds, could thus be exposed to temperatures outside of their preferred range. In 2019, cameras were installed on the cliffs of Stora Karlsö, which has the Baltic Sea’s largest colony of common guillemots (Uria algee). These cameras made it possible to study the thermoregulatory behavior of common guillemots. Due to seabird species adaptation for minimal heat loss and a rise in global temperature, the common guillemot constitutes an interesting study species. This study aimed to answer the two following questions: How often do common guillemots exhibit thermal regulation? Which variables affect the frequency of thermal regulation in common guillemots? To investigate thermoregulatory behavior and potential drivers, this study included a basic pilot study, behavioral analyzes and regression analyzes to explore potential causal relationships. Due to previous studies five behavior were suggested to indicate thermal regulation in common guillemots of Stora Karlsö; Panting, Raising scapular feathers, “Screaming”, Orientation toward the sun and Seeking shadow. During June 2019, the guillemots showed thermoregulatory behavior 22 of 28 days. Two separate regression analyzes indicate that 18,57 % of the variability of the thermal regulation can be explained by temperature and 84,83 % of the variability can be explained by direct solar radiation. This study observed possible trade-offs and thermal adaptations. Natural Sciences Naturvetenskap
5	Evaluating the use of photography for monitoring feeding habits of common murre (Uria aalge) Rydevik, Elin January 2021 (has links) Seabirds are often used as indicator species for changes in marine ecosystems due to the species visibility and sensitivity to changing conditions, such as changes in prey abundance. They often reside in habitats affected by anthropogenic impacts such as large-scale fisheries and pollution. Understanding the connection between seabirds and their surrounding environment can give us important insight about the ecology of the ocean and how anthropogenic pressures affects it. Studying feeding habits, and foraging behavior especially, is useful for understanding seabird´s responses to changing environments. Feeding studies are commonly used in seabird monitoring and requires a lot of time and resources. Monitoring of seabirds are also logistically challenging, and the risk of disturbing bird colonies must be considered. It can be especially complicated when studying cliff nesting seabirds such as the common murre, Uria aalge, the study species for this thesis. Photography as a method for monitoring seabirds may limit the need of people on site, hence minimize disturbance and save time and resources. This study provides insight in whether it is a viable option to use photography instead of on-site field studies when monitoring sea birds. This was accomplished by installing cameras and monitor a feeding study at Stora Karlsö, Sweden, parallel with performing the usual monitoring in the field. This thesis makes it clear that a camera study very well could replace the field study without any larger concerns, although, improvements need to be considered if the study is to maintain a high quality and for results to be reliable.

6	En gropkeramisk rundtur på Gotland : GIS-analyser av gropkeramiska lokaler på Gotland och osteologiska bedömningar av resursutnyttjande / A Pitted Ware round-trip on Gotland : GIS-analyses of Pitted Ware Culture sites on Gotland and osteological assessments of resource utilisation Eriksson, Albin January 2019 (has links) The aim of this master thesis is to expand on the understanding of the resource utilisation on the 19 Gotlandic Pitted Ware Culture sites: Ajvide, Alvena, Fridtorp, Grausne, Gullrum,Gumbalde, Hau, Hemmor, Hoburgen, Ire, Kinner/Tjauls, Rangvide, Barshalder, Stenstugu,Stora Förvar, Sudergårds II, Visby, Västerbjers and Västerbys. The study utilises theoretical frameworks such as Site Catchment Analysis, Site Territorial Analysis and Optimal ForagingTheory and is based on two main questions: Which animals did the diet on each site consist of? And are there any apparent connections between diet and topography/environment? To answer these questions, osteological records have been studied to get an idea of the animal food resources utilised on each site. ArcGIS has also been used to create height- and soil maps with contemporary shorelines which show how the sites were located in the middle Neolithic Gotlandic landscape. The study has shown that most sites appear to have included a variety of animals like pig/boar, cattle, sheep/goat, fish, seal, porpoise and birds in their diet. The sites with the lowest number of confirmed animals also tend to have undergone the least archaeological investigation, suggesting that further excavations on these sites might unearth more animal species. Additional discoveries show a small albeit noticeable emphasis on marine animal resources, especially porpoise, on southern sites. Sites located in areas mostly consisting of sandy, meager soils also show an increased marine resource utilisation. This might suggest that the area around these sites were somewhat barren and lacking in terrestrial prey animals. pitted ware culture neolithic site catchment analysis site territorial analysis optimal foraging theory diet resource food settlement stone age seal shoreline landscape gropkeramisk kultur gotland mellanneolitikum diet resursutnyttjande näringsfång boplats stenålder säl strandlinjer landskap Ajvide Alvena Barshalder Fridtorp Grausne Gullrum Gumbalde Hau Hemmor Hoburgen Ire Kattlunds Kinner Tjauls Rangvide Rojrhage Stenstugu Stora Karlsö Stora Förvar Sudergårds Visby Västerbjers Västerbys Archaeology Arkeologi
