1. 36. Evolution of Interactions Involving Intrinsically Disordered Proteins

   Författare :Emma Åberg; Per Jemth; Madan Babu; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; intrinsically disordered proteins; protein evolution; phylogenetics; ancestral sequence reconstruction; biophysical characterization; NCBD; CID; p53; MDM2; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution; Biokemi; Biochemistry;

   Sammanfattning : This thesis describes the evolution of intrinsically disordered proteins and their interaction partners. The work presented is a combination of phylogenetic analysis, ancestral reconstruction and biophysical characterization in order to examine the evolutionary trajectory of protein-protein interactions involving disorder.

3. 37. Relationships between nomenclature, phylogenetics and systematics

   Författare :Yann Bertrand; Mikael Härlin; Mieczyslaw Wolsan; Södertörns högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PhyloCode; philosophy; systematics; individuality; natural kind; possible worlds; causal theory of reference; PhyloCode; philosophy; systematics; individuality; natural kind; possible worlds; causal theory of reference;

   Sammanfattning : Systematists have become increasingly aware of the limits imposed by the current system of nomenclature for accurately representing evolutionary relationships and managing efficiently names associated with clades. In reaction, a new system of nomenclature, the PhyloCode is being developed that fully recognizes the historical nature of taxonomy and the importance of the cladistics revolution. LÄS MER

4. 38. Proteomics and phylogenetics of the Gnetales

   Författare :Chen Hou; Catarina Rydin; Niklas Wikström; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; växtsystematik; Plant Systematics;

   Sammanfattning : A central point of Darwin’s theory of evolution is that accumulation of many small changes during the evolutionary process can result in significant change over time. In light of his theory, plant scientists seek for and compare different plant traits among species e.g. LÄS MER

5. 39. Molecular phylogenetics and taxonomic issues in dragonfly systematics (Insecta: Odonata)

   Författare :Rasmus Hovmöller; Thomas Pape; Mari Källersjö; Kjell Arne Johanson; Karl Kjer; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Systematics and phylogenetics; Systematik och fylogeni;

   Sammanfattning : Dragonflies (Odonata) are one of the ancestral groups of extant insects. They represent one of the three most basal branches in the phylogeny of winged insects. The other two groups are the Ephemeroptera, mayflies, and Neoptera, the latter which covers the remaining winged insects. LÄS MER

7. 40. Species Limits, and Evolutionary History of Glassfrogs

   Författare :Santiago Castroviejo-Fisher; Carles Vilà; Jennifer A. Leonard; Miguel Vences; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Amphibia; Anura; Biogeography; Centrolenidae; Diversification; Frogs; Molecular Phylogenetics; Neotropics; Pristimantis; Speciation; Species; Systematics; Taxonomy; Systematics and phylogenetics; Systematik och fylogeni; systematisk zoologi; Systematic Zoology;

   Sammanfattning : Recognizing the mechanisms of speciation and the limits of species is essential to understand the origin of biodiversity and how to conserve it. The general aims of my investigations during my doctoral studies were two-fold: to study evolutionary patterns and processes, and to provide specific and superspecific taxonomic classifications that try to reflect evolutionary history.
