1. 6. Ecological and evolutionary assembly processes and metacommunity structure

   Författare :Mikael Pontarp; Evolutionär ekologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Community; metacommunity; phylogenetic signal; ecology; evolution; assembly process; marine bacteria; habitat filtering; competition; mathematical modeling; simulation; eco-evolutionary;

   Sammanfattning : This thesis aims to elucidate the link between abiotic and biotic effects and biogeographical contingencies, eco-evolutionary assembly processes, and community structure in a spatially explicit metacommunity framework. To this end, we used structure analysis of naturally sampled and experimentally manipulated marine bacterial communities and mathematical eco-evolutionary modeling and simulations of metacommunity assembly.

3. 7. Labour mobility and plant performance : The influence of proximity, relatedness and agglomeration

   Författare :Rikard Eriksson; Urban Lindgren; Gunnar Malmberg; Andrés Rodríguez-Pose; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Agglomeration economies; labour mobility; plant performance; geographical proximity; related variety; clusters; Human geography; economic geography; Kulturgeografi; ekonomisk geografi; Economic geography; Ekonomisk geografi; Social and Economic Geography; kulturgeografi;

   Sammanfattning : The purpose of this thesis is to shed new light on the theorizations discussing the economic benefits of geographical clustering in a space economy increasingly characterized by globalization processes. This is made possible through the employment of a plant-perspective and a focus on how the relative fixity and mobility of labour influence plant performance throughout the entire Swedish economy.

4. 8. Genetic structure and dispersal in plant populations

   Författare :Johan Fogelqvist; Martin Lascoux; Sophie Gerber; Beng-Olle Bengtsson; Uppsala universitet; []
   Nyckelord :population genetics; dispersal; structure; plant; gene flow;

   Sammanfattning : This thesis focuses on the spatial structure and methods to identify spatial structure in plants. Methods that investigate genetic structure can mainly be divided into equilibrium methods that reveal summed dispersal over many generations, and cluster methods, that reveal more recent dispersal events.

5. 9. Populärmusik, kluster och industriell konkurrenskraft : En ekonomisk-geografisk studie av svensk musikindustri

   Författare :Daniel Hallencreutz; Ola Jonsson; Uppsala universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Social and economic geography; economic geography; industrial clusters; competitiveness; music industry; cultural industries; Sweden; Kulturgeografi; Human geography; Kulturgeografi; kulturgeografi; Social and Economic Geography;

   Sammanfattning : The economic importance of design-intensive and cultural-products industries has grown in recent decades. One case in point is Sweden, where internationally competitive industries have emerged in areas such as multimedia, fashion, and music. LÄS MER

7. 10. Nonmarket Interactions and Density Externalities

   Författare :Johan P. Larsson; Johan Klaesson; Martin Andersson; Henri de Groot; Jönköping University; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

   Sammanfattning : The four individual papers in this thesis all explore some aspect of the relationship between productivity and the density of economic activity.The first paper (co-authored with Martin Andersson, and Johan Klaesson) establishes the general relationship between regional density and average labor productivity; a relationship that is particularly strong for workers in interactive professions.
