1. 1. Chicken domestication : Effects of tameness on brain gene expression and DNA methylation

   Författare :Johan Bélteky; Per Jensen; Anna Kukekova; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Domestication greatly increases phenotypic variation in a short time span, with selection for a single phenotype and a plethora of associated phenotypic changes as an outcome of the process. The domestication process influences the underlying genomic architecture of a species, and the success and speed of the process is likely influenced by it. LÄS MER

3. 2. Student Sustainability Consciousness : Investigating Effects of Education for Sustainable Development in Sweden and Beyond

   Författare :Daniel Olsson; Niklas Gericke; Jelle Boeve-de Pauw; John Piccolo; Jan Činčera; Karlstads universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Education for sustainable development; effects; environmental and sustainability education; holism and pluralism; students; sustainability consciousness; Biology; Biologi;

   Sammanfattning : Environmental and sustainability education has been an important part of education worldwide for many years, aiming to foster pro-environmental behavior among young people. Education for sustainable development (ESD) and its teaching components holism (the approach to the content) and pluralism (the approach to teaching) has been launched as the educational approach to support this aim by empowering young people with action competence for a sustainable future.

4. 3. Reproductive physiology of the female three-spined stickleback, Gasterosteus aculeatus

   Författare :Chrysoula Roufidou; Bertil Borg; Geir Lasse Taranger; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; overripening of eggs; spawning cycle; brain-pituitary-gonad BPG axis; vitellogenin; ovarian fluid; sex steroids; reproduction; three-spined stickleback; Gasterosteus aculeatus; fish; funktionell zoomorfologi; Functional Zoomorphology;

   Sammanfattning : Reproduction in vertebrates, including fishes, is under control of the brain-pituitary-gonad (BPG) axis. The female three-spined stickleback, Gasterosteus aculeatus, produces egg clutches at intervals of a few days and spawns them in a nest built by male. LÄS MER

5. 4. Experimental Evolution : and Fitness Effects of Mutations

   Författare :Anna Knöppel; Dan I Andersson; Stanley Maloy; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Experimental evolution; Fitness effects; mutations; S20; fis; ribosome; horizontal gene transfer; adaptation; synonymous mutations; Mikrobiologi; Microbiology;

   Sammanfattning : Bacteria have small, streamlined genomes and evolve rapidly. Their large population sizes allow selection to be the main driver of evolution. With advances in sequencing technologies and precise methods for genetic engineering, many bacteria are excellent models for studying elementary questions in evolutionary biology. LÄS MER

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

   Författare :Nicolas Innocenti; Erik Aurell; Mogens Jensen; KTH; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER
