Den här uppsatsen försöker besvara frågan om hur man kan förmedla känslor, tankar och stämningar till människor med trädgården som medium. Uppsatsen söker även svar på om man specifikt kan designa gröna miljöer som riktar sig till människor som går igenom ett sorgearbete. Här ges exempel på flera olika designteorier och olika sätt att tänka kring hur man skapar meningsfulla landskap. Därefter presenteras forskning kring hur människor tar sig igenom ett sorgearbete och bemöter känslor av sorg. Uppsatsen tar även upp Appelton?s teorier kring habitat och prospect/refuge och hur människan förhåller sig till rummet. Vad som avgör vår känsla av trygghet och de underliggande mönstren i hur vi läser av vår omgivning. I den avslutande delen av litteraturstudien går jag närmare in på hur man kan skapa helande miljöer för människor som genomgår ett sorgearbete. I uppsatsen ingår även två utformningsförslag som är baserade på den tidigare genomgångna litteraturen kring hur man skapar trygga och helande miljöer.

This study concerns the type of vegetation selected by cattle grazing on semi-natural pastures, and whether the selection depends on the nutrient content of the vegetation or on other factors. The study was carried out in three different semi-natural pastures in the Uppsala area during June, July and August in 2006. The three pastures were first surveyed, mapped out and divided into sub-areas with regard to the type of dominating vegetation. The vegetation types identified were: wet, mesic, dry, wooded, pasture with signs of former cultivation (arable). Within each vegetation type three 1x1 m sampling plots were laid out. The grazing behaviour of the cows was recorded in a behaviour study.

Wood pellets are an upgraded product of residuals from several wood processing industries, for example saw mills and pulp industries. The pellets are produced by pressing the milled and dried sawdust to cylindrical units with a higher density than the initial raw material. Pellets have great benefits compared to the raw material: high energy per volume, good transport and storage properties and homogeneity. Several parameters collaborate in the whole process, which makes it complex. Wood is a heterogeneous material, chemically and structurally dependent on wood parts, habitat and storage procedures.

The aim of this review is to assess the ethical implications of aquaculture, regarding fish welfare and environmental aspects. The aquaculture industry has grown substantially the last decades, both as a result of the over-fishing of wild fish populations, and because of the increasing consumer demand for fish meat. As the industry is growing, a significant amount of research on the subject is being conducted, monitoring the effects of aquaculture on the environment and on animal welfare. The areas of concern when it comes to animal welfare have here been divided into four different stages: breeding period; growth period; capturing and handling; and slaughter. Besides these stages, this report includes a chapter on the current evidence of fish sentience, since this issue is still being debated among biologists.

The Lodgepole pines susceptibility to Heterobasidion spp. was investigated in three parts ofthis study. In the first part, discs from freshly cut stumps were collected and analyzed to seeif the fungi can spread and grow naturally in Lodgepole pine stands. In the second part, rootsamples were collected from Lodgepole pines planted in former infected Norway sprucestands to see if the fungi can spread through root contacts. For the third part, new stumpswas created and artificially infected with spores of both the S?type (H.

Within literature, politics and science, there is a claim that ?tree avenues are important?. But the question and the goal for this essay are to explore the pretext to how and why. Planting tree avenues is a 4000 year old tradition and they are a common element in the Swedish and Scanian landscape since the 18th century. They were first mainly planted by aristocratic land-owners or on their initiative, but since the 19th century also by farmers.

Vole populations in northern Scandinavia vary in cycles with peaks every third or fourth year as described by the National Environmental Monitoring Programme of small mammals (NEMP). Some vole species have declined in population numbers since the NEMP started in 1971, especially the grey-sided vole (Myodes rufocanus) which is nearly extinct in the forested region. Since small mammals are an important food source for several avian and mammalian predators, the decline in vole numbers is expected to have consequences for the whole food chain, especially if other vole species start to decline in numbers. This study tried to test the hypothesis that presence and abundance of M. rufocanus (a specialist species) and Myodes glareolus (a generalist species) can be predicted by patch size and connectivity of forest patches >60 years old with a minimum of 15% pine >100years old.

Urban trees contribute significantly to our society. By providing ecosystem services and a habitat that other urban species and ecosystems depend on, both biodiversity and the people in the city benefit. Some characteristics that the trees possess include functioning as biological filters for the atmosphere and water, as well as positively impacting people's mental health. However, urban trees are challenged by stressors such as pollution and a drier environment, making them particularly sensitive to climate change. The goal of this study was to estimate the expected magnitude of climate change in Gothenburg and compare it with the current urban species' natural climate boundaries to understand the extent of the climate threat and which species appear to be most at risk.

Stone walls in agricultural land are incorporated in the general protection of biotopes. They are protected because they provide a habitat for endangered species. Therefore it is illegal to carry out proceedings in an area that is included in the protection of biotopes. In order to do that, exemption is needed which can only be granted if there are special reasons. The essay stipulates what these special reasons are.In an exemption errand the interest for nature conservation must be weighed against a public or a private interest.

Kantzoner är områden där olika ekosystem möts och de varierar i skarphet och omfattning. Områdena erbjuder hög biologisk diversitet då de är en blandning av de mötande ekosystemen samt erbjuder särskilda mikroklimat. Den biologiska diversititen påverkas av bredden, längden och strukturen på kantzonen och de har en biologisk betydelse i och med att de erbjuder habitat, skydd och föda till flera arter. För att påvisa var i landskapet det finns kantzoner kan verktyget GIS användas. I arbetet användes GIS för att avgränsa områdena som arbetet skulle handla om samt för att slumpa ut punkter för inventering i kantzonerna i dessa områden.

Den största delen av vår svenska kust gränsar till Östersjön, vilket gör att vi alla påverkas av dess miljötillstånd. Östersjön är ett förorenat innanhav med ett känsligt djur- och växtliv. Östersjön är redan, utan de antropogena föroreningarna, ett ogästvänligt habitat att leva i för både djur och växter. Detta beror delvis på att vattnet är bräckt och att arterna måste anpassa sig till dessa förhållanden, dels att det råder en naturlig syrebrist i vattnet. Även andra faktorer spelar in.

ABSTRACTThe principal aim of the study was to compare the feeding behaviour of cattle, sheep and goats on pasture and explain any differences between speices. Furthermore, I compared foraging behaviour between dry season and the beginning of the rainy season, in order to see any relationships between weather and behaviour.The study was carried out in Shompole in southern Kenya. Behavioural data were collected by observing herds of cattle, sheep and goats on pasture. The livestock were herded on pasture during the days and kept in bomas, where people live, during the nights. The weather in Shompole is characterized by high ambient temperature and low, bimodal rainfall.

Naturbetesmarker är artrika och näringsfattiga habitat vars utbredning kraftigt har minskat under 1900-talet. Historiskt fyllde de en viktig funktion som fodermarker men har idag till stor del ersatts av åker och vallodling. Naturbetesmarker bör idag bevaras av andra syften, både biologiska och kulturella. De rymmer en stor mängd rödlistade arter och visar spår av historisk markanvändning. Många naturbetesmarker har tidigare varit betesmarker eller slåtterängar och när hävden upphör växer det öppna landskapet igen. I denna studie har effekterna av restaurering genom kraftig röjning och förnyat bete studerats.

Heath star moss (Campylopus introflexus) is an alien species in Sweden and is currently classified as composing a "very high risk? of becoming invasive in the country according to SLU, and has in several parts of the world taken over large areas in a short time. The moss is characterized by its preference for disturbed and burned land, something that occurs on the heathland in the Sandsj?backa nature reserve, when burning for nature conservation purposes is carried out annually. Sandsj?backa's heathland is a valuable ecosystem and is one of the few heathlands in a favorable condition that remains in Sweden after strong reforms in modern agriculture in the last century, which led to forest succession of these cultural environments.

Genom att undersöka begrepp som natur, det vilda och det sublima, i en idéhistorisk tillbakablick baserad i västerländsk kulturtradition, presenteras en ny möjlighet för efterbehandling av kalkstensbrottet Västra brottet i Slite på Gotland. En analys av platsen och tidigare nämnda begrepp leder till en förändring av det befintliga förslaget på efterbehandlingsplan. Denna aktuella efterbehandlingsplans tyngdpunkt ligger i införande av habitat. Förslaget i detta arbete är att en ?social efterbehandling? som har möjlighet att aktivera hela orten tillförs.
