2. 1. Diurnal variation of stratospheric short-lived species

   Author : Maryam Khosravi; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; chlorine monoxide; short-lived species; Arctic ClO; diurnal variation; tropical middle stratosphere; Arctic stratosphere;

   Abstract : Diurnal variation of stratospheric short-lived speciesMaryam KhosraviChalmers University of TechnologyDepartment of Earth and Space SciencesAbstractThe depletion of ozone in the stratosphere has a direct impact on the amount of ultravioletradiation reaching the Earth’s surface. The ozone abundance and distributionis controlled by the photo-chemical reactions and catalytic cycles involving halogens(chlorine and bromine), odd hydrogen and odd nitrogen species as well as by atmospherictransport.

4. 2. Local adaptation in life history traits and population size estimation of aquatic organisms

   Author : Konrad Karlsson; Monika Winder; Johan Ehrlén; Juha Merilä; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; local adaptation; intraspecific variation; niche partitioning; life history; global warming; recreational angling; spatial capture–recapture; Marine Ecology; marin ekologi;

   Abstract : Human society is dependent on healthy aquatic ecosystems for our basic needs and well-being. Therefore, knowledge about how organisms respond and interact with their environments is pivotal. READ MORE

5. 3. The importance of wetlands for biodiversity in agricultural and urban landscapes

   Author : Elisabeth Lundkvist; Linköpings universitet; []
   Keywords : Dytiscidae; diving beetles; wetland; pond; diversity; assemblage; CCA; ordination; variation partitioning; community structure; flight; migration;

   Abstract : The aim in this thesis was to study the importance of different types of wetlands for the biodiversity in a landscape. The landscapes were both agricultural and urban, and wetlands were in different successional stages. Diving beetles (Dytiscidae) were used as study organisms. READ MORE

6. 4. Life-history traits and population differentiation in a clonal plant: implications for establishment, persistence and weediness

   Author : Johanna Eneström; Biologiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; weediness; Clonal plant; resource sharing; resource storage; partitioning of genetic variation; seedling development; seed recruitment; Aegopodium podagraria;

   Abstract : Clonality is wide-spread among plants, and clonal plants dominate many habitats and include many highly invasive species. Clonal growth incurs both advantages and costs and clonal plants often have reduced sexual reproduction compared to non-clonal plants which could be expected to lower genetic variation and hence evolutionary potential.

7. 5. Extracting Genomic Variations using Selector Technology

   Author : Magnus Isaksson; Mats Nilsson; Radoje Drmanac; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Selector; Selector probe; Genetic variation; Resequencing; Targeted sequencing; copy-number variations; MLGA; Bioinformatics; Next generation sequencing; NGS; Amplified single molecule; ASM; Molecular medicine genetics and pathology ; Molekylär medicin genetik och patologi ; Genetics; Genetik; Molekylär medicin; Molecular Medicine;

   Abstract : This thesis describes the development and use of a new class of molecular tools called Selector probes, and its potential for investigations of genetic variation. The Selector technology provides multiplex amplification of targeted DNA sequences with a high specificity, and an enrichment factor in the same order of magnitude as PCR. READ MORE
