Bevarande av svensk låglandsboskap
Sweden signed, in 1992, the Convention on Biological Diversity (CBD) and has thus assumed responsibility for the indigenous biodiversity. That also means that Sweden has a conservation responsibility for the Swedish Friesian (SLB) (SJV, 2007a). In a survey conducted by the Board of Agriculture (SJV) in 1996, it appeared that there were around 780 cows and heifers of the SLB breed (SJV, 1997). SJV did in 2006 a plan for the development of livestock genet-ic resources and the number of cows of SLB was estimated at approximately 200. This meant that the SLB was in need of being conserved and SJV assumed it would be categorized as threatened.The primary objective of conservation of a breed is to reduce the loss of the original genetic variation (Lacy et al., 1995).
En j?mf?rande studie mellan tv? v?treng?ringsmetoder p? papper
Amongst the published literature researching wet cleaning of paper there is a limited amount of
studies conducted researching the method simmering water treatment. There are even less studies
conducted on how simmering water affects the paper being treated when used as a cleaning method.
Despite the limited research, there are literary reviews describing the method and suggesting it as an
alternative for conservation of paper with iron-gall ink. The following study will therefore be
examining, the somewhat unusual method, simmering water treatment, and comparing it to one of
the more common wet cleaning methods: immersion washing. This is done to compare how the
different temperatures of the water affect the paper.
The types of paper used in this study consists of three dyed and four undyed papers. All of the papers
are new, apart from one sample originating from 1847.
Konstruktion av analysverktyg för studie av Nature of Science i fysikläroböcker - En studie av fem gymnasieläroböcker
I examensarbetet har läroboksserier inom fysik för gymnasienivån studerats med avseende på Nature of Science. Begreppet Nature of Science, NOS, handlar om naturvetenskapens epistemologi och de sammanhang som påverkar skapandet av ny kunskap inom naturvetenskap. Aspekter från andra vetenskapsområden som, historia, filosofi, ekonomi, och sociologi lyfts fram som viktiga i kunskapsutvecklingen av naturvetenskap. Som grund för studien har ett avgränsat avsnitt, som i examensarbetet benämnts vad är ljus, undersökts. Inom detta område har det studerats om och hur NOS används i läroböckerna.

En vandring genom Skymningssagors land : Samhällskritik, konst, natur och saga i Gustav Sandgrens Skymningssagor
Abstract The aim of this study is to create a pathway through Gustav Sandgren?s short-story collection Skymningssagor and the second collection with that title, based on his social criticism, notions of art and nature, use of fairytale motifs and finally, his view of the metaphoric liberation of mankind. The study is based on a comparative and thematic investigation, illustrated by examples from Sandgren?s short stories. The theoretical framework is based on Eva Nordlinder?s study of the art fairytale in Sekelskiftets svenska konstsaga och sagodiktaren Helena Nyblom (1992) and Konstsaga och Kultursyn (1992) as well as Torben Brostrøm?s study of the folktale in Folksagan och den moderna litteraturen (1992). The investigation shows that Sandgren?s social criticism permeates his short stories, but that his keys to salvation, nature and art (first and foremost music) exist to help mankind rise above our shackles. The investigation also shows that Sandgren?s short stories are firmly placed within the tradition of the fairytale and the romantic notion of a relation between nature and man. Keywords social criticism, fairytale, nature, music, art, liberation.
Identitet, skog, fjäll och ren i Härjedalen : ur ett samiskt perspektiv
This paper examines how nature is understood in the province of Ha?rjedalen by the sami population of the area, through interviews with three informers and photographs taken by the author. Pictures and answers point in the direction that much of nature is understood through the reindeer, the most important key symbol of the reindeer herding part of the sami people and their kin..
Environmental variables determining the occurrence of Cladonia parasitica and Hertelidea botryosa, two boreal lichens confined to wood
Biodiversity is essential for human well-being and it is defined as the genetic variation within species and the variety of species and ecosystems. Biodiversity provides several ecosystem services which are necessary for human beings but there are different threats towards the
biodiversity. The biodiversity linked to the forest in Sweden are threatened, about 50 % of the red-listed species in Sweden are associated with forests. This is linked to the commercial exploitation of the boreal forest in Sweden which started 200 years ago. The forestry the last
50 years, with clear-cuts, have contributed to a fragmented forest landscape.
Kiviksgraven : analys av dess historia och framtid sett utifrån bevaringsfrågor
This essay focuses upon the Kivik monument and its conservation difficulties, since its discovery at 1748 until modern time. The Kivik monument is found in southeast of Scania, and dated within the Bronze Age period. The perspective of the conservation on the monument has merely been on the monuments inner cist of stone and the rock carvings on the cist-slabs. When the monument was first archaeological examined at 1931, its sizeable cairn (75 m in diameter) had almost vanished and the cist was sheltered by a casing of concrete and metal roof. Between 1932 and 1933 the monument has undergone a large-scale restoration, and this criticized restoration resulted in a low antiquarian value with the responsible authority.
Från ett nödvändigt ont, till en naturtyp värd att bevara - en studie av ljungheden i Sandsjöbacka och Grönabur/From a necessary evil to a nature type worth protect - a studie of the Calluna heath of Sandsjöbacka & Grönabur
In the middle of the 19th century was Calluna heath the major nature type in Halland, but the remaining parts today is only 1 500 hectares which is a 99 % decrease of the Calluna heath mainly due to an increase in forest plantations and arable fields. I have made a quantitative study how the Calluna heath of Grönabur & Sandsjöbacka has changed between 1841 and 2005 and why it didn?t disappear in the same manner, as it did in other parts of Halland. The studying of original sources as historical maps, literature and by doing field visits has been significant for the final result. The main reason for the different development of the Calluna heath in the investigation area (69 % decrease), compare to elsewhere in Halland, is the establishment and management of a nature reserve..
Attityder till återintroduktion av visent i Sverige
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.
Bildandet av naturreservat : uppföljning och klimatanpassning
AbstractWe are facing a century of rapid change in climate, with significant challenges in managing the impact of changes in living conditions for plants and animals. We can already see the responses of species through changes in phenology and spatial distribution, which may change ecosystem structure and function, with subsequent effect on ecosystem services and biological diversity. In Sweden, between 2005 and 2010, the red-listed species has increased by 13 % and similar trends can be seen across the world, making it difficult to attain national and international environmental objectives of preserving biodiversity. One way to reduce the loss of biodiversity is to protect nature from exploitation by allocating valuable areas as nature reserves, but climate change affects protected areas just as much as other landscapes and therefore requires elaborate systems of protection to facilitate species' survival. The paper has examined how the decisions and management plans for nature reserves in Sweden have been followed-up and whether they are climate adapted or not by examining 30 nature reserves, classified as newly formed (2012), recently revised (2009-2011) and older (1977-2007) reserves, and assessed what is in the decisions and management plans for follow-up, revision, long-term goals and documentation.
Wetland development in the context of ecotourism : a conceptual design proposal for a wetland site in Lake Victoria, Kenya
The travelling sector is expanding worldwide, which puts all destinations under pressure to have a functioning
social system and good resources to manage the problems and take advantage of the opportunities that the
tourism sector can offer a community. The area around Kisumu in Kenya, like much of Africa, tourism can
simultaneously ensure a stable financial future while it removes, as a result of a growing population, more and
more of the scenery that many tourists want to experience. Responsible travel to natural areas that promotes
conservation of the environment and improves the welfare of local people is what defines ecotourism. A
concept that implies a closed cycle, where visitor?s needs are met in balance with what can be given back,
without risking creating imbalances in society.
Along the coast of Lake Victoria, valuable papyrus wetlands provide Kisumu vital ecosystem services
such as water purification, climate adaptation while it also serves as a reservoir for biodiversity.
Kampen mot de fyra storbankerna
Outdoor recreation habits in metropolis and rural areasThis study aims to examine the perception of nature and outdoor recreation habits from an urban-rural prospective. The urbanization process continues in Sweden and the populations of the cities are growing continuously. Trends to build more compact and ?climate smart? reigns and with this a risk that green areas and areas where outdoor recreation can be practiced are situated further and further away from the urban population. Analyzing the responses from a survey made by the research program Friluftsliv i förändring 2007 we have examined if and which differences exists between urban and rural areas regarding their perception of nature, outdoor recreation habits and factors influencing the practice of outdoor recreation.
