Factors affecting bark-stripping by red deer (Cervus elaphus) : the importance of landscape structure and forage availability

Bark-stripping by red deer (Cervus elaphus) cause extensive damage to economically valuable spruce trees (Picea abies) in Swedish forests. The underlying causes for bark-stripping are not fully understood, and the frequency and severity of damage unpredictably differ between regions. In this study, I investigated if landscape structure (e.g. agricultural dominated landscape opposed to forest dominated landscape), forage availability, population density and disturbance (e.g. roads and settlements) affect bark-stripping frequency.

Datering av röta i hålekar :

I have chosen in this work to examine which factors are affecting the artificially creation of a tree cavity containing decomposed wood. The purpose of the work is to find out which factors are affecting the most when a tree cavity is created, and to apply these results when you artificially try to create a tree cavity. The need to create tree cavities comes from the situation where many tree cavity living beetles finds themselves today. When existing trees are to pass out there will be no suitable inheritors yet. The work was initially to focus on cavities created from cut branches.

Effekterna av urbanisering, barksprickedjup och solexponering på lavfloran i sydöstra Sverige

Studies have shown that air pollution, as well as bark fissure depth and sun exposure of a tree can have an effect on lichen growth as well as abundance of lichen species. The aim of this study was to find out the relative importance of these factors. 211 oaks in south eastern Sweden were surveyed for presence of 17 lichen species, as well as the total number of lichen species. Half of the trees were situated in urban areas and half in the countryside. For each tree the bark fissure depth was measured and the sun exposure of the trunk was estimated.

Föreningsengagemang och politiskt deltagande ? en tvetydig historia : En studie av Högsby och Växjö kommunfullmäktige

AbstractThe political parties in Sweden are losing members. This is seen as a problem because the political parties are the base and the recruiting ground for members to decision-making bodies. Social movements are seen as a place where people with a modest background could express their opinions and also learn the political process. These movements have also lost members during the last decades and this could seriously affect the representation of lower social groups among the decision-makers. This essay emanates from Robert D.

Hur en ökad marktemperatur påverkar fotosyntes och markrespiration i en boreal skog

During the year of 2008, a powerful earthquake hit the southern part of Iceland, which changed the geothermal conditions in the area around the city of Hveragerdi. Elevated soil temperatures in a nearby forest plantation have contributed to a unique opportunity for researchers to study how an increased soil temperature affects the boreal forest ecosystem, something that partly can be connected to the climate changes which are happening today. The boreal forest is representing a carbon sink and a buffert for the emissions that occurs. Changes in this ecosystem will for that reason contribute to major impact for the global carbon cycle. To study the impact of how elevated soil temperatures affects different processes in a plantation of Sitka spruce, studies were made on the photosynthesis of the trees and the respiration from the soil.

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.

Non-state actors? role in the EU forest policy making : a study of Swedish actors and the Timber Regulation negotiations

The purpose of this research is to identify how E-NGO and forest stakeholders, in the study referred to as non-state actors, have influenced the EU timber regulation; through participation and lobbyism towards the decision- makers (policy makers) at EU and national level, to achieve adjustments in the legislative text. The study also examines the relationships between the forest stakeholders, the E-NGOs and the EU-institutions, regarding communication, cooperation, informal and formal consultation where interviews were accomplished with decision-makers from the EU-institutions, forest stakeholders, E-NGOS and representatives from Swedish authorities that participated under the development of the EUTR during the period of 2008-2013. The participation and lobbying from non-state actors have most likely affected the outcome of the regulation, through alterations in the legislative text and through influencing the EU-institutions. Several factors that have affected the efficiency and timing of the influence have been identified through interviews as well as various approaches to influence the decision makers. The findings of the study may be useful for forest related interest groups that are involved in decision-making procedures at EU-level and as substance and material for further research in the subject of forest policy making at supranational level..

Emotionsreglering och stämningsläge som faktorer för högt och lågt risktagande i beslutsprocessen

The purpose of this thesis is to investigate the ways in which emotion regulation and mood affects risk taking when it comes to decision making competence. Emotion regulation is an essential part of the attachment process, the development of an autonomous self and functional stress coping systems. Research indicates that there is a relation between a distorted emotion regulation and some psychological disorders like depression, PTSD, anxiety disorders and borderline (or instable emotional personality disorder). There is a definite need to analyze the relation between emotion regulation and decision making competence since it is relatively unexplored. A digital questionnaire was distributed amongst the participants.
