Studier av habitatval och revirstrukturer hos vassångare (Locustella luscinioides) i Tåkern
The Savi?s Warbler (Locustella luscinioides) is a recently established bird species in a few reedy shallow lakes of southern Sweden and has only been found nesting for the last twenty years. Little is known about the species' habitat preferences, breeding biology and demands for specific territory structures at breeding sites in Sweden. Knowledge of a newly established species? habitat requirements is essential to maintain a viable population and design action plans.
Vallbrott med hjälp av grisar :
To investigate the possibilities for effective soil tillage, that could imply lower costs,
lower negative environmental impact and in addition a meaningful occupation for foraging pigs, a field experiment was carried out in Gränna, Småland, during growing season 2006.
The experiment contained two treatments that were repeated three times and were carried
out on a couch grass-infected fallow on a light soil close to Sweden?s second largest lake, Vättern. Ploughing was one treatment and pig rooting followed by ploughing, was the
other. The experiment was conducted according to the guidelines of organic growing and
seedbed preparation was done the same way in the two treatments. The pigs, three groups
of five half-year old Linderödssvin (an old Swedish breed), was encouraged to perform
an even tillage by strip-grazing, i.e.
Systematisk bedömning av våtmarksväxter som substrat för biogasproduktion
Två miljöproblem idag är ökade koncentrationer av växthusgaser i atmosfären och övergödning. Därför är två utmaningar att reducera utsläppen av växthusgaser och flöden av näringsämnen. Ytterligare en utmaning är att trygga energiförsörjningen i en värld där efterfrågan på energi ökar. Nya förnybara energikällor behöver utvecklas både för att trygga energiförsörjningen men även för att minska användandet av fossil energi. En förnybar energikälla är biogas som kan användas till el, värme och fordonsgas.
Evaluating six crop mixes used for game fields in southwest Sweden : biomass production, fallow deer preference and species diversity
Game fields are one way to divert animals away from sensitive areas, create shelter and forage, and also to increase the biological diversity. In this study I investigated how the plant composition in six different crop mixes used for game fields affected the biomass production, biomass consumption and biological diversity at the Koberg estate in southwestern Sweden. Six experimental fields were used and each field contained six plots, approximately 1500 m2 each, that was sown with a different crop mix. The crop mixes ranged from a pure grass mix (A), 70 % grass and 30 % leguminous plants (B), 53 % grass, 21 % leguminous plants and 26 % other herbs (C), 100 % leguminous plants (D) to the most complex mixes constituting of 91 % leguminous plants and 9 % other herbs (E) and 87 % leguminous plants and 13 % other herbs (F). The fields were cut weekly during the summer in 2010, to estimate weekly biomass production.
Spansk skogssnigel (Arion lusitanicus) i ensilerat vallfoder : betydelse för fodrets näringsinnehåll och hygieniska kvalitet
This work is about silage contaminated with slugs (Arion lusitanicus). The hypothesis was: Do slugs affect the nutritional value and hygiene quality of silage? During the winter season 2007/2008 silages were discarded in big amounts due to the contamination of slugs. Both the Swedish Farmer Association (LRF) and the National Veterinary Institute (SVA) received phone calls from farmers and animal owners about contaminated silage. The Swedish University of Agricultural Sciences (SLU) and SVA decided to initiate this project as a master thesis.
Fodder to ruminants within agroforestry systems in Rwanda - species and management
Rwanda is one of the poorest countries in the world and about 70-80 % of the population lives in rural areas. The land is strongly affected by land erosion which makes it difficult for the agriculture and food production. Agroforestry is a system where tree plantation is combined with livestock- and crop production. The system provides soil fertilization and binds the soil together. Some of the trees used in agroforestry systems are also used as fodder.
Växters förmåga att ackumulera metaller : Vass, bredkaveldun och gäddnate i Bergviks dagvattendamm
AbstractSurface-water includes different kinds of pollutants from traffic and roads. To prevent these pollutants to reach nearby lakes one can construct surface-water ponds on locations with heavy traffic. At Bergviks shopping centre in Karlstad, two ponds, one smaller and one bigger has been constructed in order to decrease the pollutant pressure from the receiving waters of Kattfjorden. Several heavy metals are essential for plants and animals in low concentration but when they occur in higher concentrations, they become toxic to the organism. The larger pond at Bergviks shopping centre has a sedimentation function so the heavy metals sink to the bottom thereby not releasing directly in to Kattfjorden.
In search for sustainable alternatives to lawns : connecting research and landscape design
A large part of Sweden?s green, urban landscape is covered by lawns. Approximately 80 000 ha of maintained grass lawns are part of public courtyards, schoolyards, parks, golf courses, sport fields and traffic environments. Beyond this figure, the lawn is also an essential element in most private villa-gardens. Lawns have become a universal phenomenon through the dispersion of landscape aesthetics from the Western world.
Den skönlitterära politiska spegeln : En tematisk analys av The Grass is Singing och Disgrace
Fotbollspelaren Zlatan Ibrahimovic var 2010 och 2011 den mest omskrivna sportprofilen i svensk press och Aftonbladet och Expressen har varsin reporter på plats i Milano för att bevaka honom och hans lag AC Milan. Syftet med denna C-uppsats är att ta reda på vad sportjournalister på Aftonbladet och Expressen tror är anledningarna till att det skrivs så mycket om Zlatan Ibrahimovic. Vidare vill vi ta reda på hur de skriver om honom, varför de skriver som de gör, vilka egenskaper Zlatan Ibrahimovic har som gör att det skrivs så mycket om honom samt vad det stora fokuset på honom får för konsekvenser. I vår analys kommer vi koppla resultatet till teorier som maskulinitet inom sportjournalistiken, virvelvindseffekt och tabloidisering.Vi har gjort en kvalitativ undersökning med hjälp av halstrukturerade djupintervjuer. Totalt har vi genomfört fem intervjuer med reportrar, krönikörer och nyhetschefer på de två kvällstidningarna i Sverige.
Fodertillgång och stereotypa beteenden under natten hos Asiatisk elefant (Elephas maximus)
Animals in zoos live in more barren environments than their conspecifics in nature. In nature, elephants spend more than 75 % of the day foraging and have been observed lying down two hours during night. Stereotypies are common in many different species in zoos. Stereotypic behaviors may constitute up to 50 % of the daily activity budget of zoo elephants. Modern zoos try to reduce stereotypic behaviors by means of environmental enrichment.
Utfodring av föl före och efter avvänjning :
Swedish horse breeders have generally very few mares producing a few foals a year and the
breeders have relatively few traditions, little knowledge and experience to breed foals
successfully. It is therefore important to provide adequate information about new findings in horse nutrition. However, there is not much research about feeding the suckling foal to ensure a sound growth. Current feeding recommendations in the literature seems to be different. This gives a confusing message and the information is difficult to apply.
This paper reviews some publications in the area of feeding the suckling and weaning foal.
Most authors stress that it?s important to start feeding the foal early in life.
Synen på den avvikande individen i film : En analys av The Elephant man och Kaspar Hauser
Ämnet som jag har undersökt är synen på den avvikande individen i film. I min analys har jag använt mig av David Lynchs The Elephant man (1980) samt Werner Herzogs Kaspar Hauser (1974). Min analys är gjord utefter den hermeneutiska metoden och är således utarbetad efter mina egna tolkningar och reflektioner kring filmerna. Teorierna jag har använt mig av är postkolonialism och makt.I min slutsats har det framgått att det kan vara en mångfald anledningar till hur och varför människor väljer att behandla de avvikande individerna på sättet de gör. Dock så framgår det att de som behandlar de avvikande väl oftast motiverar sina handlingar genom att de finner sympatier för de utsatta.
En ekonomisk hållbar växtodling i sörmländsk mellanbygd :
We have been looking at three different types of agriculture in Södermanland, in the middle
east of Sweden. We call the different types for Intensive, Extensive and Mix. The purpose is
to get an economic defensible plan for how to run different farm sizes. We also have been
looking at the working hours and how many hours the different types will give.
We have a farm called Taxinge Gods as our pilot farm. Taxinge Gods grow 407 ha land and is
located 60 km southwest from Stockholm.
Vattendraget på Kåbo golfbana : en kartläggning som ett steg i golfklubbens miljöarbete
This degree project studied surface waters on Kåbo Golf Course in Uppsala, Sweden, with the aim of determining the status of the water and how it is affected by the activities of the golf club, and to obtain suggestions of measures to create better conditions for the water environment on and around the golf course. The project forms part of the environmental protection work of Kåbo Golf Club, which is working towards achieving environmental certification from the Swedish Golf Association (SGF).
The study is based on literature studies and quantitative and qualitative field studies of water on the golf course, with the focus on environmental factors identified as being important for the golf industry and on strategic environmental goals developed by SGF.
The number of open water bodies in the Swedish landscape has substantially declined during
the past 200 years, so it is important to save those that remain. This study showed that the surface water at Kåbo Golf Course is an important element in the surroundings since the area contains few wetlands, which can be a habitat for large numbers of species. The stream and ponds on Kåbo Golf Course also have the important function of serving as water hazards in the game and adding difficulty and variety to the course. Since Kåbo Golf Club wants its surface waters to look aesthetically appealing, extensive algal growth and drying up of ponds during parts of the year are regarded as problems.
Lokala skillnader i konsumtion av påväxtalger och terrestra löv hos en differentierad population av Asellus aquaticus
That ecological and evolutionary processes can take place on the same time scale is a recent insight. Today we also know that they are directly linked to each other. In the lake Tåkern, in year 2000, there was a structural change when phytoplankton declined and submerged vegetation, mainly stoneworts began to spread. This led to evolutionary changes in the aquatic sowbug, Asellus aquaticus which had previously been limited to the reed, most likely feeding on detritus. But then, sowbugs could exploit the new habitat in stoneworts and a new food resource in terms of periphyton.
