  1. 21. Karaktäristiken hos strukturmarken på olika altitud i Abiskoområdet – en koppling till klimat och komplex systemteori

    Författare :Gunnar Scharin; Christer Jonasson; Johan Kling; Uppsala universitet; []
    Nyckelord :Abisko; patterned ground; permafrost; non-sorted circles; altitude; self-generation; Geovetenskap med inriktning mot miljöanalys; Earth Science with specialization in Environmental Analysis; Earth Science with specialization in Physical Geography; Geovetenskap med inriktning mot naturgeografi; Biology with specialization in Ecological Botany; Biologi med inriktning mot ekologisk botanik;

    Sammanfattning : Subarctic and alpine areas are sensitive to climatic change when they lie at the margin of permafrost occurrence. Patterned ground in such areas is generated from an interplay among different mechanisms such as temperature, hydrology, soil texture, snow cower and vegetation. LÄS MER

  3. 22. Breeding of Swedish Warmblood horses towards specialization in show jumping and dressage

    Författare :Sandra Bonow; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : A clear specialization towards show jumping or dressage performance is evident in most European Warmblood studbooks. As a consequence, some breeding organizations have introduced specialized breeding programs. LÄS MER

  4. 23. Deciphering molecular mechanisms in the evolution of new functions

    Författare :Hind Abdalaal; Joakim Näsvall; Paul Rainey; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Evolvability; functional trade-offs; collateral toxicity; duplication and amplification; Biologi med inriktning mot mikrobiologi; Biology with specialization in Microbiology; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution;

    Sammanfattning : The evolution of new genes and functions is considered to be a major contributor to biological diversity in organisms. Through de novo origination, “duplication and divergence”, and horizontal gene transfer, organisms can acquire new genetic material that can evolve to perform novel functions. LÄS MER

  5. 24. Mine the Gaps : Evolution of Eukaryotic Protein Indels and their Application for Testing Deep Phylogeny

    Författare :Pravech Ajawatanawong; Sandra Baldauf; James McInerney; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; indel; insertion deletion; protein evolution; bioinformatics; non-bilateria; eukaryotes; phylogeny; Biology with specialization in Systematics; Biologi med inriktning mot systematik; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution;

    Sammanfattning : Insertions/deletions (indels) are potentially powerful evolutionary markers, but little is known about their evolution and few tools exist to effectively study them. To address this, I developed SeqFIRE, a tool for automated identification and extraction of indels from protein multiple sequence alignments. LÄS MER

  7. 25. Genetics and Growth Regulation in Salmonella enterica

    Författare :Jessica M. Bergman; Diarmaid Hughes; Dan I. Andersson; Måns Ehrenberg; Stanley Maloy; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; tufA; tufB; EF-Tu; ppGpp; Stringent response; RNase E; RNA turnover; Post-transcriptional regulation; rpoB; rpoS; Growth in stationary phase; Biology with specialization in Microbiology; Biologi med inriktning mot mikrobiologi; Mikrobiologi; Microbiology; Molekylär genetik; Molecular Genetics; Biology with specialization in Molecular Evolution; Biologi med inriktning mot molekylär evolution;

    Sammanfattning : Most free-living bacteria will encounter different environments and it is therefore critical to be able to rapidly adjust to new growth conditions in order to be competitively successful. Responding to changes requires efficient gene regulation in terms of transcription, RNA stability, translation and post-translational modifications. LÄS MER
