2. 1. Exploring the species boundaries in terrestrial clitellates (Annelida: Clitellata)

   Author : Svante Martinsson; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Oligochaeta; species delimitation; Clitellata; Annelida; DNA-barcoding; cryptic species; Enchytraeidae; Lumbricidae; Naididae;

   Abstract : The biological diversity in the soil is much higher than most people can imagine, and a very important group of animals living there are earthworms and other clitellate worms. It has been found that several clitellate morphospecies are in fact complexes of so called cryptic species, and the number of species in this group may be much higher than previously believed.

4. 2. Genomic and morphological diversity of marine planktonic diatom-diazotroph associations : a continuum of integration and diversification through geological time

   Author : Andrea Caputo; Rachel Ann Foster; Monika Quinones Winder; Ramon Massana; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; phytoplankton; diatoms; cyanobacteria; diazotrophs; symbiosis; evolution; phylogenetics; confocal microscopy; qPCR; CARD-FISH; tropics; sub-tropics; Marine Ecology; marin ekologi;

   Abstract : Symbioses between eukaryotes and nitrogen (N2)-fixing cyanobacteria (or diazotrophs) are quite common in the plankton community. A few genera of diatoms (Bacillariophyceae) such as Rhizosolenia, Hemiaulus and Chaetoceros are well known to form symbioses with the heterocystous diazotrophic cyanobacteria Richelia intracellularis and Calothrix rhizosoleniae.

5. 3. Data Analysis and Next Generation Sequencing : Applications in Microbiology

   Author : Nicolas Innocenti; Erik Aurell; Mogens Jensen; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; RNA-seq; tagRNA-seq; primary and processed RNA; Enterococcus faecalis; Complex transcription; Metagenomics; 5 tagRACE; minimal absent words; compressed sensing; metagenomics; bacterial community reconstruction; Biologisk fysik; Biological Physics;

   Abstract : Next Generation Sequencing (NGS) is a new technology that has revolutionized the way we study living organisms. Where previously only a few genes could be studied at a time through targeted direct probing, NGS offers the possibility to perform measurements for a whole genome at once. READ MORE

6. 4. Stochastic modelling and analysis of early mouse development

   Author : Sofia Tapani; Göteborgs universitet; []

   Abstract : The aim of this thesis is to model and describe dynamical events for biological cells using statistical and mathematical tools. The thesis includes five papers that all relate to stochastic modelling of cells. READ MORE

7. 5. Functional studies of plant hexokinases and development of genetic methods in the moss Physcomitrella patens

   Author : Mikael Ulfstedt; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Abstract : In the field of biology, model systems are frequently used for practical reasons. Model organisms possess several features that make them easy to work with in a laboratory setting. In addition they usually have a host of established genetic tools that have been developed by the research community. READ MORE
