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.

It is hard to find streaming waters where humans haven?t affected the fish populations or the running water it self. In many streams the fish populations are over harvested and this results in a lack of older and larger fish. This is also the situation for many populations of Grayling (Thymallus spp.). To be able to develop management plans and to perform actions that improve the situation for the grayling, it is therefore crucial to know what natural, by humans unaffected populations look like.

Ammerån which is a small forest river in eastern Jämtland is a well-known river that has been a popular fishing river for a long time. The actual Ammerån begins downstream the lake Solbergsvattnet at Hammerdal and flows into the Indalsälven 10 km upstream Hammarstrand. The river environment switches between forests with wilderness feeling and open agricultural land. The entire Ammerån is today a nature reserve and protected from hydropower development. Fishing in Ammerån has mainly been focused on trout and grayling, and is so even today.

This thesis aims to analyze the similarities and differences in how identity is constructed by the European Commission, the Council of Ministers and the European Parliament regarding the Polish membership and the potential Turkish membership of the European Union. The construction of identity is analyzed through a social constructivist perspective where identity is constructed by distinguishing ?us? from ?them?. The research metod used is a qualitative text analysis. The arguments of identity are taken from the Commission?s and the Council?s documents, as well as from the debates of the European Parliament.

European identity is a topic constantly debated around Europe. There are many takes on whether there is a European identity and what the European identity consists of. In the European Union the Commission has worked towards developing a common European identity since the middle of the 1970?s. The development of a European identity is an important part in the commission?s quest to tie the union and its people closer together.

This thesis treats the normative power of the European Union and its affect on Macedonia. The main purpose has been to look closer with the use of the application of Ian Manners theory of normative power on the Macedonian case. The focus will be to answer the following questions: Does the European Union act as a normative power in relation to Macedonia, if so, how are these values diffused? Has there been any effect of the spreading of these values? Based on six interviews and the available material of European Union strategies for the Macedonian membership I have attempted to understand to what extent the European Union?s normative power has had an influence in Macedonia. The result of my analysis is confirmation of the European Union as a normative power in Macedonia and the understanding of the methods of application..

After the fall of the Iron Curtain the European Union was challenged partly by an institutionalized organization of the union, as well as by a socio-psychology awareness concerning the meaning of the European Union. The increase in European integration has generated a political collaboration where national understandings in identities are constantly being exposed for reconstruction. This results in a collective European identity where states are united in diversity.National identities are created when boundaries are set up in a relation to other states. In these identity constructions there are thoughts and questions raised such as who we are and who we are not. Ukraine and the European Union has, during a long time, had diversified preconceptions concerning who has been the others.

Public opinion has increasingly become a political force in the European integration process. At present, it appears that the people?s attitude towards the European integration is relatively skeptical. How can we expect that the attitude towards European integration will evolve in the future? This paper tests the extent to which diffusion theory can serve as a model to explain the development of attitudes to European integration policy in Sweden from 1999 until 2009.

What is the European Union (EU) and which countries should be part of it in the future? These questions became topical during the first part of the 21st century when political and geographical changes hasten the need to decide the nature of the European cooperation. In the European Constitution, that never come into force, the European values that a key role but was taken away in the succeeding Lisbon Treaty. Nevertheless EU continues to expand, recently to the East and non-European countries asTurkey are now on the ?waiting-list?.

This thesis treats the development of the European Union asylum- and migration politics and the EU member states transfer of authority to the European Union. The main purpose has been to look closer with the use of the application of theory of neofunctionalism and liberal intergovernmentalism on the European Union case. The focus will be to answer the following questions: How has the political development within EU asylum and migration policy developed through the period of The Single European Act to the ratification of the Stockholm program? And how can the chosen theory explain European countries transfer of national decision regarding asylum policy in favor of a supranational European asylum policy? Based on the available material of European Union programs and harmonization measures for this area I have attempted to understand to what extent the European Union?s development in the area of the asylum and migration politics can be explained through the theories of neofunctionalism and liberal intergovernmentalism. The result of my analysis is confirmation of the European Union development of the area of the asylum and migration policy and also a series of explanations according to the theories regarding the member states transfer of authority to the EU.

This study aims at describing if discrepancies can be found between the rhetoric in Swedish political parties? electoral campaigns to the European Parliament elections in 2004 and their representatives? actual behavior in the European Parliament and to develop plausible explanations to these possible discrepancies. The research method that is being used is content analysis, aiming to answer four research questions regarding the electoral campaigns to the European Parliament elections in 2004 and the behavior by the parties? representatives during the following term of office. The main findings are that some discrepancies can be found regarding which questions are raised most frequently in the electoral campaigns and in the European Parliament, but that no discrepancies can be found regarding the positions taken in questions in the electoral campaigns and in the European Parliament.

The European union started as an area of economic cooperation, but has developed into an area of cooperation in many legal fields. There are these days even cooperation when it comes to dealing with criminals. There is a new procedure called the European arrest warrant which goal is to make the extradition of criminals between the different member states in the European union more efficient. Sometimes when a state receives a European arrest warrant they have to extradite the person in question without doing any investigation of their own. The procedure is based on the principle of mutual recognition.

A qualitative document analysis is used to answer the aim of this thesis that is to find out if the relation between the European Union and Belarus has changed from confrontational to reparational in between the two parliamentary elections that was held in the country in the years of 2004 and 2008. The study focuses on debates from the European parliament in association to the elections in Belarus to see if the rhetoric used in the debates have changed. It is found that the rhetoric used in the European parliament after the 2004 election in Belarus are extremely confrontational and the members of the debate expresses their thoughts of Belarus in a rather harsh way. It has also been found that the rhetoric used in the European parliament after the 2008 election in Belarus are more diplomatic and have the tendencies of a warmer relation to Belarus although there are still some confrontational views among the members..
