2. 1. Labour mobility and plant performance : The influence of proximity, relatedness and agglomeration

   Author : Rikard Eriksson; Urban Lindgren; Gunnar Malmberg; Andrés Rodríguez-Pose; Umeå universitet; []
   Keywords : 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;

   Abstract : 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. 2. Establishment, Growth and Population Dynamics in two Mosses of Old-growth Forests

   Author : Karin Wiklund; Håkan Rydin; Staffan Karlsson; Lloyd Stark; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biology; Buxbaumia viridis; Neckera pennata; bryophyte; pH; phosphorus; water potential; precipitation; metapopulation; environmental stochasticity; ecology; plant; Biologi; Biology; Biologi;

   Abstract : Biodiversity in forests depends on long canopy continuity and existence of different elements which function as substrates for varying organisms. Bryophytes often occupy specific substrates with a patchy distribution. READ MORE

5. 3. DYNAMIC MODELLING OF BIOGEOCHEMICAL PROCESSES IN FOREST ECOSYSTEMS

   Author : Salim Belyazid; Avdelningen för kemiteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Naturvetenskap; marklära; Silviculture; forestry; forestry technology; Skogsvetenskap; skogsbruk; skogsteknik; Natural science; Lantbrukshydrologi; Soil Science; agricultural hydrology; Växtekologi; Forest Soil Acidification; Plant ecology; Plant biochemistry; Forest Growth; Vegetation biodiversity; Carbon Sequestration; Nitrogen Leaching; Miljökemi; Dynamic Modelling; Växtbiokemi; Environmental chemistry;

   Abstract : Forests in Sweden are undergoing rapid and considerable changes regarding both management methods and environmental conditions. To understand the effects of these changes and to be able to predict impending changes in forest ecosystems, a holistic understanding of the processes governing the ecosystem is needed. READ MORE

6. 4. Nutrient imbalance in Norway spruce

   Author : Gunnar Thelin; Avdelningen för kemiteknik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Silviculture; Växtekologi; Plant ecology; nitrogen saturation; base saturation; pH; multiple limitation; deficiency; copper; boron; potassium; pollution; sustainability; conifers; forestry; forestry technology; Skogsvetenskap; skogsbruk; skogsteknik; Soil Science; agricultural hydrology; Lantbrukshydrologi; marklära;

   Abstract : The studies presented in my thesis indicate that growing Norway spruce in monoculture does not constitute sustainable forest management in a high N and S deposition environment, such as in southern Sweden. The combination of N-induced high growth rates and leaching due to soil acidification causes soil reserves of nutrients to decrease. READ MORE

7. 5. AtZDP, a Plant 3' DNA Phosphatase, Involved in DNA Repair

   Author : Isabel Valsecchi; Lars Rask; Per Jemth; Christer Larsson; Uppsala universitet; []
   Keywords : Molecular biology; AtZDP; plant long patch Base Excision Repair; DNA 3 phosphate blocking lesions; DNA repair; Molekylärbiologi;

   Abstract : DNA bases can be modified by endogenous agents (e.g. oxidized by products of respiration and photosynthesis or methylated by gene silencing processes) as well as by environmental agents (e.g. READ MORE
