Pulsatilla vernalis is one of several endangered plant species that benefit from wildfires and small scale disturbance events that repel competing vegetation and create open patches in the vegetation cover. Previous studies argue that Pulsatilla vernalis is decreasing in numbers due to vegetation changes associated with the decrease in wildfires, forest grazing and changes in forest management. In this study, 17 populations of P. vernalis were inventoried in order to examine if soil and/or vegetation structures affect the population structure of P. vernalis (i.e.

The little steel industrial community Hofors is situated in Gästrikland on the border to Dalarna and its population is decreasing every year. The biggest housing operator is in a place where they must tear down a lot of buildings because they do not have enough tenants. But what do people really want in an apartment and in the surroundings? What is needed to make it attractive? That is something that this study will discuss and in the end it will lead to a proposal of an area that is suitable for a new housing and a few proposals to make the existing apartments more attractive..

The population of Grey Partridge is decreasing worldwide as a result of anthropogenic activities. Increased agricultural production, requiring homogenous farming landscapes and increased use of pesticides are believed to be the main factor causing population declines in the Grey Partridge. Actions to enhance Grey Partridge populations are available; however, those actions are vain if the acceptance to conduct them is low. To gather information about acceptance among farmers, hunters and the County Administrative Board towards 18 available actions enhancing the Grey Partridge population, nine face-to face interviews were conducted as an exploratory case study. The results showed that willingness to conduct enhancing actions differ between and within the groups of stakeholders.

Gotland is an island in the Baltic Sea where man has introduced roe deer. The last successful reintroduction was in the 1980s and is the base of the viable roe deer population of today.The aim of this study was to estimate the roe deer population density in 2012 and the species population dynamic since the time when studies on the population started. The result indicates a population size of 850 roe deer in 2012. There was no significant population dynamic, which may be due to insufficient data. The population occurs basically over the whole island but have not yet been established in all suitable areas.

Exocrine pancreatic insufficiency is a hereditary disease that in Sweden is especially common in German shepherds. The Swedish German shepherd club has currently no plan of action for decreasing disease prevalence in the breed. The purpose of this study was to review existing literature about the disease and also to perform an inventory of the disease in the Swedish dog population. Special focus was laid on the German shepherd breed. The inventory was later compared to an unpublished inventory of the disease with data from the Swedish University of Agricultural Sciences from 1997. During the period 2002-06-01 to 2007-09-26 (ca 64 months) 2961 blood samples were analyzed for cTLI. 274 samples were positive (cTLI .

The report is about efficiency of a current production group where there is no clear production flow and there are some buffers between the operations. The efficiency is done with the help of a tool that is calledWork process of flow production which is used by Atlas Copco CTO. The most obviously results are that the lead time drops from 25 hours to 425 minutes and that the balancing loss decreases from 85 % to 8 %. The report focus on decreasing transports, decreasing buffers, more reliability in lead time and quality. And a more stimulating labour content for the workers is another result..

The wild boar Sus scrofa population in Sweden has increased rapidly in the last decades which has led to conflicts among stakeholders, for example due to crop damages in agriculture. Thus, there is an urgent need of quantified goals and effective strategies for wild boar management. To develop such strategies, knowledge on population dynamics is fundamental. In this study a deterministic matrix model was used to estimate population growth, based on previously published data. The exponential growth rate for a wild boar population was calculated to 1.48.

Cannibalism can have major influence on fish population dynamics. A prerequisite for cannibalism is that the cannibal and the potential victim meet, and besides density effects, the encounter rate between cannibals and their victims is therefore also largely dependent on habitat use and habitat heterogeneity. In this study I quantified and compared the potential for cannibalism in stream-dwelling European grayling populations in three rivers in Jämtland by means of habitat classifications. I also analyzed population dynamic consequences of varying the potential for cannibalism in terms of intensity, using a physiological structured population model. Findings based on habitat characteristics were that the potential for cannibalism is in general not favourable in these types of streams.

This paper investigates the automatic stabilizer and the underlying factors behind its function. The paper includes both a literature review and an empirical analysis. The literature review discusses the IS-LM and Mundell-Fleming models and different ways to quantify the automatic stabilizer. Based on the theory, the relationship between volatility in GDP and the size of the automatic stabilizers is then analyzed with the help of regressions. Our main result shows a negative relation between these two variables.

Denna magisteruppsats har fokus på hur aktörer i en kommun med ett vikande befolkningsunderlag ser på fenomenet. Informanterna som medverkar är politiker, tjänstemän samt representanter från näringslivet. En kommun ingår i studien, det är Finspångs kommun i Östergötland. Uppsatsen undersöker hur dessa ser på frågan om ett vikande befolkningsunderlag. Hur man resonerar kring fenomenet och hur samspelet och samverkan mellan aktörerna uppfattas.

In the future the Swedish pension system will face major problems. With an increasing aging population combined with a decreasing share of working population the financing of the pension system is becoming a bigger problem than previously predicted. This means the individual himself will have a bigger responsibility to invest money for their future retirement. It has been shown that a large proportion of the people who invests for their future pension have neither the interest nor the time to actively invest their pension capital. To make it easier for those who invest for their retirement, some Swedish banks have created so-called generation funds.

The calculations in this thesis are evaluating the profit as a consequence from treating young stands of pine in Sweden with birch bark extract, BBE. Treatment is to be done with the object to lower or fully reduce the moose browsing on pine. The study is made in three versions. The results from each version separately will follow below. Version I.: The size of the moose population is in no way affected by the reduced resources of food as a consequence of large scale treatment with BBE on pine. Results show profit at a 3 percent level of interest with the exception of treatment program with more than 4 treatments all together and with the exception of Västerbottens Län with an early first treatment. Version II.: The population of moose decrease from 10 to 5 individuals per 1000 ha as a consequence from large scale treatment with BBE on young pine stands.
