Evaluation of an ectomycorrhizal macrofungi as an indicator species of high conservation value pine-heath forests in northern Sweden
Since the 1950s, the development of modern rotation forestry in boreal Fennoscandia has resulted in a severe reduction of older forests, and a high degree of fragmentation among the small patches that remains of old forest. In Sweden, when performing conservation value assessments in order to identify and preserve the remaining forest habitats, the government authorities use to a significant extent a set of indicator species that indicate habitats of high biological conservation value. One species considered to indicate high conservation values in pine-heath forests is the red-listed ectomycorrhizal (EM) macrofungi Sarcodon scabrosus (Fr.) P. Karst. In the present study, the validity of using S.
Biodling i Stockholms stadskärna : Ekonomi, ekologi eller ekosofi?
Previous research confirms that there is a major decline of pollinators worldwide. Investigations have mainly focused on pollination services in the agricultural landscapes and therefore, there is a lack of knowledge on the effects pollinators may have in urban environment. This paper examines the presence of honey bees in central parts of Stockholm, Sweden. The study presents what conditions, possibilities and motives there are behind the phenomenon of urban bee keeping. I found ten locations with beehives and a total of 18 hives within the delimited area. Nothing seems to indicate that conditions may limit the presence of honey bees.

This qualitative case study, made with four companies, looks closer at how more effective information management, with the help of IT-systems, affect companies market communication and relations to customers and suppliers. Customer Relationship Management perspective is used and Enterprise Resource Planning-systems are the ground for new technology change. The main conclusions are that new technology affects the outcome of companies? relationships towards their customers and suppliers and that the processes and activities between the involved parties are more closely linked. Also involving your suppliers and external actors makes the information handling more effective and companies that do so most likely have a competitive advantage..
Mode en gråzon? : En studie av modebranschens position mellan konst och kommers
The purpose of our essay is to develop an understanding and an insight for the fashion industry. We want to examine what the creative industries can learn from the unique position that fashion hold in a field between commercialization and art. We used a theoretical ground to enlarge our understanding for the distinctive place that fashion holds. To gain further insight in the fashion industry we complete the theory with empirical facts. The empirical facts were collected through a qualitative method with deep-going interviews.
Teknik för vårskörd av hampa till stråbränsle :
Hemp is an annual energy crop that fits very well in Swedish crop rotations. It is an interesting crop with many benefits, for example its ability to establish a large quantity of biomass in one year. Hemp is easy to grow and out-competes unwanted weeds through its aggressive growth pattern without the need for pesticides. Interest in growing hemp and other energy crops is currently decreasing, apparently because of high grain prices. These high prices give a higher net profit that we believe could partly cover the cost of hemp cultivation, while the hemp in turn would improve the crop rotation and thus repay its debts in the form of increased yields of other crops.
The great disadvantage of hemp is the lack of knowledge about spring harvest of the crop.
Meningsförändrande innovationer inom industrirobotbranschen : En explorativ fallstudie
In this thesis the subject innovation and the change of meaning is in focus. The purpose of the study is to present a new dimension of innovation as a change of meaning together with the cases we?ve studied. It is discussed throughout the article if theories of perception and association can affect the organization and its ability to create meaning-changing innovations. The industrial robotics is a market in need of, perhaps, if not other markets but of finding new ground that results in the change of meaning.
Brand i förorten : En studie av etiken i journalistiken
A great fire seized a suburb in a small town in Sweden in the autumn of 2011. Parts of a shopping mall were burnt to the ground by youngsters. Due to the suburb's earlier problems, the event was a tough ethical dilemma for the town's journalists.The purpose of this thesis was to study and examine the local newspapers ethical treatment of this event. How do they motivate their decisions on what to publish and what not to publish? How do the articles treat ethical dilemmas? What do the journalists think about ethical journalism?This study is based on a survey of the articles published about the fire in the two local newspapers seven days after the fire.
Trädslagsinverkan på markvegetationens utveckling i odlingsförsök med tall och contorta :
In the 1970?s it was predicted that in the beginning of the 21st century there would be a timber shortage in Sweden and a large scale introduction of the exotic tree species lodgepole pine started. An introduction of a foreign tree species means a risk of a negative influence on the forests ecosystem. Today, the stands that were established in the 70?s are middle-aged and the effect on the forest floor vegetation can be studied.
Realistisk interaktiv miljö
Spel och simulatorer som skall avspegla existerande miljöer måste för spelaren vara trovärdiga vad gäller landskap, arkitektur, attribut och ljussättning. För att kunna bygga och implementera sådan realistiska och trovärdiga miljöer krävs ett grundligt förarbete med referensmaterial, skissarbete och tester. Under 10 veckor har jag gjort mitt examensarbete tillsammans med Försvarshögskolan och Data Ductus AB på ett projekt som vi kallar för Foreign Ground. Det har resulterat i en djupgående förstudie och research som ska bli en bra grund för att skapa en demonstrator till ett utbildningsspel. Spelet är tänkt att användas för träning av FN-soldater som är på väg till Liberia på utlandsmission.
Effekten på nedbrytningen av rötter vid tillförsel av ammonium sulfat i en granskog i sydvästra Sverige
Decomposition of organic matter is a critical process in the ecosystem, which involves many essential biotic and physical parts. Decomposition is therefore an important process both above and below ground. The rate of decomposition is dependent of many environmental factors for example: pH, moisture and supply of oxygen. The decomposition can therefore be affected by large scaled environmental influences, such as acidification and climatic changes. The root litter in the forest is in different ways affected by acidification, liming and manuering.
Död ved och förekomsten av två mossor som indikerar skoglig kontinuitet
Studiens syfte är att undersöka arterna Buxbaumia viridis och Nowellia curvifolia för att kunna förutse var man hittar dessa signalarter. Detta gjordes genom att död liggande ved undersöktes i Ycke naturreservat samt en närliggande brukas skog, Östergötlands län.Resultaten visar att faktorerna som är avgörande för B. virids är markkontakt och nedbrytningsklass. B. viridis föredrar att växa på lågor i de högre nedbrytningsklasserna (4-7) och med stor andel markkontakt, över 80 %.

Framtidens forntid : Geofysisk och geokemisk prospektering av järnåldersgården RAÄ 108, Fresta sn, Uppland
This paper deals with archaeological prospection of an Iron Age farm site in Toland, Fresta parish, Uppland County in Sweden. The purpose of the paper has been to see whether the geophysical methods applied (GPR & EM-38) could produce useful results that could motivate its use in similar surveys in the future. Geochemistry has been used for the purpose of identifying possible activity areas on the site. The results have shown that it is possible with a GPR survey to identify postholes originating from the Migration Period longhouse at the site. The combining of several methods have been important for the identification and interpretation of several areas of interest..
