1	Hur markegenskaper i produktionsskog påverkas av bök från vildsvin (Sus scrofa) i sydvästra Sverige Petersson, Linn January 2019 (has links) A balance between large-scale and small-scale disturbance is important for maintaining species diversity on landscape level. Wild boar rooting contributes to small-scale disturbance when leaving patches bare of soil. Knowledge is scarce regarding their impact on soil properties in managed spruce forests in south-west Sweden. Therefore, the objective of this study was to determine the effects of wild boar rooting on soil physical and chemical properties, by taking soil samples from the centre, the edge and outside of disturbed patches. Rooting activities significantly increased soil moisture, organic matter, total N and pH but did not affect total P in this study. Areas with high number of disturbed patches had higher soil moisture and organic matter compared to areas with intermediate and few disturbed patches. These new soil characteristics can favour species diversity and ultimately increase productivity in managed forests. The results of this study indicate that wild boar activity contributes to more positive than negative effects in managed spruce forests and focus should therefore lie on preventing wild boar rooting in other areas more sensitive to this disturbance. It is also important to disseminate information and knowledge about the wild boar's positive and negative impact on managed forests in order to better prevent the negative effects and strengthen the positive ones.

2	Vildsvinsbök i skogsmark – en studie i tre områden i Mellansverige Lundquist, Kristin January 2016 (has links) I april-juli år 2010 undersöktes tre studieområden i mellersta Sverige avseende hur fördelningen av vildsvinsbök såg ut i dessa områden. Resultaten visade att vildsvinsbök främst återfanns i miljöer dominerade av tall-och granskog där åldern på träden låg runt 45-90 år, samt med fältskikt bestående av bärris, mossa eller gräs. På två utav de tre lokalerna påverkades inte arealen på bök av faktorer såsom trädartsammansättning, trädålder eller fältskikt men det fanns däremot korrelationer mellan dessa faktorer på en utav lokalerna. Vidare påverkades arealen på bök inte av populationstäthet eller hur lång tid vildsvin förekommit i området. / In April-July in 2010, three forest dominated areas in central Sweden were studied to investigate wild boar rooting habits. The results showed that rooting mainly occurred in pine-and spruce dominated habitats where tree-ages varied between 45-90 years old and with ground surface vegetation consisting of shrubs (blueberry/lingonberry), mosses and grass. In two of the three study areas the size of rooted areas was not affected by factors such as tree species composition, forest age or vegetation ground cover, but correlations between these factors were found in one of the areas. The size of rooted areas was not affected by the population density or the time with wild boar present in the area. wild boar rooting wild boar rooting forest tree species composition forest age ground surface vegetation vildsvin bök vildsvinsbök skogsmark trädartsammansättning trädålder fältskikt Ecology Ekologi Miljö- och naturvårdsvetenskap
3	Dissensus and Poetry: The Poet as Activist in Experimental English-Canadian Poetry Leduc, Natalie 28 January 2019 (has links) Many of us believe that poetry, specifically activist and experimental poetry, is capable of intervening in our society, as though the right words will call people to action, give the voiceless a voice, and reorder the systems that perpetuate oppression, even if there are few examples of such instances. Nevertheless, my project looks at these very moments, when poetry alters the fabric of our real, to explore the ways these poetical interventions are, in effect, instances of what I have come to call “dissensual” poetry. Using Jacques Rancière’s concept of dissensus and the distribution of the sensible, my project investigates the ways in which dissensual poetry ruptures the distribution of the sensible—“our definite configurations of what is given as our real, as the object of our perceptions and the field of our interventions”—to look at the ways poetry actually does politics (Dissensus 156). I look at three different types of dissensual poetry: concrete poetry, sound poetry, and instapoetry. I argue that these poetic practices prompt a reordering of our society, of what is countable and unaccountable, and of how bodies, capacities, and systems operate. They allow for those whom Rancière calls the anonymous, and whom we might call the oppressed or marginalized, to become known. I argue that bpNichol’s, Judith Copithorne’s, and Steve McCaffery’s concrete poems; the Four Horsemen’s, Penn Kemp’s, and Christian Bök’s sound poems; and rupi kaur’s instapoems are examples of dissensual poetry.
