Background: Parasite evolution is hypothesized to select for levels of parasite virulence that maximise transmission success. When host population densities fluctuate, low levels of virulence with limited impact on the host are expected, as this should increase the likelihood of surviving periods of low host density. We examined the effects of Morogoro arenavirus on the survival and recapture probability of multimammate mice (Mastomys natalensis) using a seven-year capture-mark-recapture time series. Mastomys natalensis is the natural host of Morogoro virus and is known for its strong seasonal density fluctuations. Results: Antibody presence was negatively correlated with survival probability (effect size: 5-8% per month depending on season) but positively with recapture probability (effect size: 8%). Conclusions: The small negative correlation between host survival probability and antibody presence suggests that either the virus has a negative effect on host condition, or that hosts with lower survival probability are more likely to obtain Morogoro virus infection, for example due to particular behavioural or immunological traits. The latter hypothesis is supported by the positive correlation between antibody status and recapture probability which suggests that risky behaviour might increase the probability of becoming infected.

Master of Science / Department of Biology / Brett K. Sandercock / Cattle-grazing is a dominant land use in the United States, with more than 300 million hectares of land grazed each year. The habitat changes facilitated by cattle grazing can influence resource availability and habitat selection for associated wildlife. To investigate the potential for changes in traditional livestock management to restore native grassland and riparian habitat, we evaluated biological community responses to winter-grazing and livestock exclusion at the Kansas Army Ammunition Plant in southeastern Kansas. In grassland habitats, we combined winter-grazing by domestic cattle and discontinued fertilization in an attempt to restore pastures dominated by tall fescue to native tallgrass prairie and improve habitat for grassland-breeding birds. We observed a decrease in tall fescue and an increase in native, warm-season grasses in winter-grazed pastures compared to fertilized, year-round grazed pastures. Grassland-breeding bird responses to winter-grazing were species-specific. Dickcissels preferred winter-grazed pastures, while Eastern Meadowlarks and Grasshopper Sparrows tended to prefer year-round grazed pastures. Dickcissels were negatively correlated with the presence of cattle during the breeding season and the abundance of tall fescue. Grasshopper Sparrows were negatively correlated with native, warm-season grass abundance and visual obstruction, but were positively correlated with forb abundance. Henslow’s Sparrows and Common Yellowthroats were detected breeding in low numbers on pastures that had been winter-grazed for five years. Our results suggest that winter-grazing and discontinued fertilization of agricultural grasslands can direct semi-natural plant communities toward tallgrass prairie and benefit some grassland-breeding birds. In riparian habitats, livestock were excluded from 1996 to 2005. We measured bird community responses in grazed and ungrazed sites using baseline data collected in 1996-97 and post-treatment data collected in 2004-05. Riparian bird community data were analyzed using robust design mark-recapture models that allowed us to evaluate changes in bird species richness while accounting for differences in detectability among species. We detected increases in species richness in both ungrazed and grazed treatments. We observed few differences in community vital rates between treatments; however, we did detect differences in guild responses. The changes observed within both grazed and ungrazed riparian bird communities were likely influenced by regional fluctuations in species richness and composition.

One of the Government's environmental quality objectives is to achieve a poison free environment, meaning that the presence of anthropogenic substances in the environment should not pose a threat to human health or biodiversity. Such a substance is chlorinated aliphatic hydrocarbons which have been used historically in dry cleaning and as degreasing agents within industrial processes. In recent years, negative effects on human health have been found since exposure to chlorinated solvents is associated with toxic and carcinogen effects, which has resulted in constrictions against such substances today.At the former Whirlpool industry in Himmelstalund, in Norrköping, the chlorinated solvents perchlorethylene (PCE) and trichlorethylene (TCE) have been used historically during production. Concentrations of PCE and TCE and their degradation products cis–1,2–dichloroethylene (cis–1,2–DCE) and vinyl chloride (VC) have been detected in groundwater at the site. This Master´s thesis aimed to develop a site–specific groundwater flow model and a mass transport model to simulate the spread of these compounds through the saturated zone after 10, 30 and 75 years. The groundwater model was developed in MODFLOW and calibrated based on known hydrological and geological conditions after which a sensitivity analysis was performed regarding hydraulic conductivity and effective porosity. It was found that the flow model generated flows which corresponded to measured ones when hydraulic conductivity was employed within the range 10–5–10–2 m/s and effective porosity in the range 5–25%.It was found that PCE, TCE and cis–1,2–DCE did not reach the surface water recipient Motala river within 75 years, the compounds traveled 500 meters west of the source zone as furthest. However, VC reached Motala river within ten years, depending on which initial concentration were applied. The plume of VC remained in the aquifer after 75 years containing concentrations exceeding the guideline values in groundwater. This is considered severe since chlorinated solvents are toxic and cancerogenic to humans.A sensitivity analysis with regard to adsorption and reaction parameters was performed where it was found that the adsorption greatly affected the spread of the plumes and was more influencing than how the reaction parameters were applied. When maximum adsorption was employed, PCE, TCE and cis–1,2–DCE remained adjacent to the source zone while VC moved about 500 meters. It was seen that the mobile properties of the compounds were considerably larger for all components when minimal adsorption was applied. Hydraulic conductivity had a major impact on transport times where higher hydraulic conductivity resulted in faster transportation through the aquifer.As the spread through the aquifer was largely affected by which parameters were chosen, it was assessed relevant to measure hydraulic conductivity, adsorption constants and measure groundwater levels in more points spread in the model area in order to improve the reliability of the mass transport model.

Den fasta egendomen i Sverige utgörs av mark och är indelad i fastigheter. För att ändra fastighetens utsträckning eller rättigheter som är kopplade till denna görs det genom fastighetsbildning som ansöks vid en lantmäteriförrättning. Dessa lantmäteriförrättningsärenden handläggs av de statliga eller kommunala lantmäterimyndigheterna. Är någon av sakägarna i förrättningen missnöjd med lantmätarens beslut, kan denna överklaga beslutet till mark- och miljödomstolen. Domstolen fattar därefter beslut i ärendet. Anser domstolen att lantmäterimyndighetens beslut är felaktigt eller bristfälligt, kan de återförvisa ärendet. Denna studie har därmed undersökt varför dessa förrättningar återförvisas. Syftet med studien är att öka kunskapen om återförvisade förrättningsärenden. Ur en samhällsekonomisk- och rättssäkerhetssynvinkel är det angeläget att hanteringen kring lantmäteriförrättningar blir mer effektiv.  För att genomföra studien har en studie av domar och intervjustudie genomförts. Intervjuer genomfördes med förrättningslantmätare och ett tekniskt råd från mark- och miljödomstolen samt Mark- och miljööverdomstolen. Under intervjuerna framkom det att ämnet är viktigt och att lantmäterimyndigheterna är en välorganiserad myndighet. I studien har det använts 119 återförvisade ärenden. Dessa har efter bearbetning kategoriserats och visat att största anledningen till att ärenden återförvisas är på grund av formella fel. Lantmäterimyndigheten har vid sådana fel till exempel inte redovisat skäl för beslut, brustit i sin utredningsplikt, sammanträde har inte hållits eller att rätt sakägare inte blivit kallade.  Slutsatsen blir sålunda att lantmäterimyndigheterna bör arbeta mer kring hur de redovisar skälen för besluten på ett tydligare sätt.

The thesis deals with the analysis of exhaustion of trade mark rights, it focuses mainly on the comunnity-wide exhaustion. It is based mainly on the interpretation of the case law of the European Court of Justice which is used both to describe the creation and development of the principle and to help to evaluace its importace on the field of the common market and its practical conclusions. Appart from the community-wide exhaustion, big part of the thesis is represented with the global exhaustion whose possible introduction has been topic of many discussions.

Base IEL resumo: Leitura comparativa de duas refacções da matéria de Bretanha produzidas no século XIX: Idylls of the King, de Alfred Tennyson, e A Connecticut Yankec in King Arthur's Court, de Samuel Langhorne Clemens (Mark Twain). O interesse em um estudo comparativo das duas obras é grande, uma vez que, tendo utilizado o mesmo texto como fonte básica para suas refacções - Le Morte D'Arthur (Thomas Malory) -, Tennyson e Clemens produziram obras profundamente diferentes, tanto na abordagem quanto no tratamento da matéria de Bretanha. Da comparação feita entre as alterações promovidas por um e outro autor, ao trabalharem com o texto de Malory, é delineado um interessante quadro histórico-social, bem como são levantadas algumas hipóteses relativas à manutenção do interesse literário por histórias de natureza arturiana / Abstract: Not informed. / Mestrado / Teoria Literaria / Mestre em Letras
