Epiphytic lichen flora in a boreal forest chronosequence
Epifytiska lavar utgör en viktig del av floran i den boreala zonen. Några miljövariabler är kända för att styra artrikedomen och artsammansättningen av epifytiska lavar på beståndsnivå, såsom träddiversitet, beståndsålder, fuktighet och trädens barkstruktur. Skogsbränder utgör den viktigaste störningen i boreala skogar men studier på brandeffekter på epifytiska lavar är mycket få. Detta arbete undersökte artrikedomen, diversiteten och artsammansättningen av epifytiska lavar på basala delar av björkar längs en gradient av 30 skogsbeklädda öar som skiljer sig i storlek och brandhistorik i den norra boreala zonen i Sverige. Målet med studien var att undersöka hur lavfloran påverkades av östorleken och miljövariablerna längs gradienten.
Lantbrukare och rådgivare : tillsammans kan de främja biologisk mångfald.
With the farming methods of the past century the agricultural landscape has changed. This has led to the fact that many habitats and species have been significantly reduced. Sweden is committed to the preservation of biodiversity through various conventions and laws. In the EU's Common Agricultural Policy there are currently agro-environmental schemes, which were created as an instrument for reducing the negative impacts of agriculture on nature and environment. Within this system any farmer who perform environmental measures are financially compensated for this.
Rumslig fördelning av grov gammal tall i Uppsala stad med tallticka som indikator på höga naturvärden :
Fragmentation and reduction of forest area is a threat for many forest species and their habitat. Deficiencies in forest quality, such as lack of dead wood and old trees, are one explanation of the threat. The most important action to prevent the continued loss of forest types is to protect forest, but also to restore and to create areas that not previously had high nature values. Hence one of the key strategic roles for Fritid- och Naturkontoret, Uppsala municipality, is to monitor biodiversity in the context of urban planning.
The majority of the Uppsala municipality residents live in urban areas and most of them spend some of their spare time in natural areas in cities and their immediate surroundings. Exploitation in and around Uppsala is high, but it is important that there is enough nature close to houses to meet the residents? needs of recreation.
Inventory and evaluation of Nairobi Animal Orphanage : focusing on Congo Grey African parrot, cheetah and rehabilitation
This BSc thesis is a part of an initial step of a collaboration between Skansen and Kenyan Wildlife Service (KWS) and constitutes of an inventory of the Nairobi Animal Orphanage run by KWS. Animal Orphanage takes care of orphaned and injured animals arriving from throughout Kenya. The project started out as a refuge and as a temporary place for animals in need of care and help. With time it has evolved to an establishment that resembles and functions more like an animal zoo. The aim of this inventory is to focus on how the biological needs of Congo grey parrots ( Psittacus erithacus erithacus) and cheetahs (Acinonyx jubatus) are met, in terms of management and housing.
Lönesättande samtal : samspelet mellan medarbetare och ledare
Bakgrunden till studien är mina egna tankar om hur de lönesättande samtalen inom arbetslivet egentligen fungerar nu när de har blivit alltmer vanliga på arbetsplatserna. Syftet med studien är dels att undersöka hur kommunikationen hanteras och upplevs under ett lönesättande samtal av medarbetare respektive ledare dels att utveckla kunskapen om vilken betydelse kommunikationens påverkan har för samspelet under det lönesättande samtalet. Studiens forskningsfråga har varit hur medarbetarna och ledarna upplever samspelet under samtalet, varför den sociokulturella teorin har använts tillsammans med andra kommunikativa begrepp och teorier. Studien har av den anledningen haft en fenomenologisk ansats för att få fram respondenternas subjektiva upplevelser av samspelet under det lönesättande samtalet. Som metod användes en öppen intervju med en frågeguide som innehåll ett antal olika teman som de olika respondenterna själva fick resonera kring.
Mellan makt och myt : om gravritual och brända ben från en småländsk vikingatida gravhög
For this essay, 12 liters of cremated bones from the Viking age grave mound RAÄ Berga 134:1 in Trotteslöv, Berga parish, Småland have been osteologically analysed. The aim with this paper concerned questions as sex, age, number of individuals and animal species in the grave. Further questions that have been investigated are the relationship between the osteological sexdetermination and artifacts as well as which role animals played in burial rituals and as grave goods.The grave contained a middle-aged woman and a number of sacrificed animals: two horses, two dogs, three birds, a boar and a cat. The bones were fragile and very fragmented. One of the birds was determined as a bird of prey, and that together with findings of horses and dogs indicates hunting with bird of prey, an activity performed only by powerful and wealthy individuals. The woman was buried in a mound of notable size, and with common grave goods for the time period: combs, beads, bronze and iron items. An unusual finding was textile which indicates high status. The number of sacrificed animal species also suggests that the grave belonged to a powerful individual. During the Viking age animals generally played an important role in grave rituals and as items to be used by their master in the next life.
"Det är bara för oss att gilla läget" : livsmedelskagstiftning och livsmedelskontroll ur verksamhetsutövarens perspektiv : en kvalitativ studie genomförd i kommunala skolkök

Design av interaktionsmoment för spelarmotivation
The game industry is growing by every year but for some reason the research surrounding it hasn't caught up with its rapid expansion. This study aims at expanding the knowledge surrounding one of those areas, player motivations. An empirical model has been used to identify which interaction has the highest impact on player motivation in story-driven roleplaying-games. By conducting semi-structured interviews with eight different game developers using the GameFlow model to explore the use of interactions to sustain the motivation of the player a new criteria has been identified. This additional criteria was: Alive, and it was shown to have a high impact on motivation in story-driven roleplaying-games.
Skötselåtgärder vid nyetablering av skyddszoner vid bäckar i södra Värmland :
Buffer zones play an important role for the water quality in our watercourses. When harvesting a forest close to a watercourse a buffer zone should be left. When it's not left, it will lead to radical changes in the environment for the water organisms. The overall purpose of this thesis was to illuminate the production- and environmental thinking when establishing new buffer zones in south of Värmland. The partials goals were to determine choice of tree species, ways of regenerate, occurrence of soil scarification and the occurrence of machine tracks in newly established buffer zones.
Naturläkemedel inom sjukvården
Naturläkemedel är ett område som väcker stort intresse idag och allt fler individer väljer att ta hand om sina åkommor på egen hand. Modern forskning visar på interaktioner mellan naturläkemedel och konventionella läkemedel. Eftersom naturläkemedel under lång tid uteslutande har använts i egenvårdssyfte har patienters användning av dessa produkter skett i stor utsträckning utan medverkan från den vanliga hälso- och sjukvården. Syftet med denna studie var att undersöka sjuksköterskors inställning till och kunskaper om naturläkemedel. Studien är av kvalitativ design och är baserad på sex intervjuer med sjuksköterskor verksamma vid två ortopediska vårdavdelningar i Södra Sverige.
Vägledning för djurskyddskontroll av exotiska smådjur
Exotic small animals that are commonly kept as pets include aquarium fish, cage and aviary birds, rodents, rabbits (Oryctolagus cuniculus), reptiles and amphibians. These different kinds of animals, even species within the same class, may differ markedly from each other regarding physiology and requirements. Although these species are common in both Swedish households and in pet trade, many animal keepers have a lack of knowledge about the origin and requirements of their pets. This is a cause of several health problems seen in animals which are held in captivity.
In Sweden, the county administrative boards perform all animal welfare controls.
Bruka utan att förbruka - när andra intressen än ekonomin får styra
To have a forest area close to the city is of great importance for the city population?s well being. Children develop their motor skills, concentration and imagina-tion and the adults have a place to shake of the stress from work. Forest areas are used to exercise at, play in and to find a moment of peace and silence.
The urban forest and the old farming pastures at Markussonvallen and Per-Isakssonvallen already has natural assets worth to preserve and a great potential to create more. The goal is to develop a forest with a variation of tree species and ground vegetation that will appeal to the human senses and different animal species such as birds, insects etc.
H?RNERVMOSSA I SANDSJ?BACKA NATURRESERVAT: Analys av h?rnervmossans invasivitet p? ljunghedens vegetationstyper
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.
Fågelbär (Prunus avium L.) - överlevnad, höjdutveckling och skador i unga planteringar på småländska höglandet :
Plant survival, plant damage and height growth were studied in nine wild cherry (Prunus avium L.) plantations in southern Sweden established between 2000 and 2002. All stands were located to the county of Småland. The survey was conducted during May and June in 2007. During the survey the height, diameter and quality of the cherry trees were recorded. In one stand, red ? berried Elder (Sambucus racemosa L.) was a dominant species.
