  1. 1. Speciation genomics : A perspective from vertebrate systems

    Author : Nagarjun Vijay; Jochen. B.W Wolf; C. Alex Buerkle; Uppsala universitet; []
    Keywords : evolution; speciation; genomics; vertebrate; adaptation; selection; linked selection; crow; killer whale; hybrid zone; transcriptomics; population genetics; behaviour; colouration; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Abstract : Species are vital entities in biology. Species are generally considered to be discrete entities, consisting of a group of (usually interbreeding) individuals that are similar in phenotype and genetic composition, yet differ in significant ways from other species. READ MORE

  2. 2. Bioinformatic Analysis of Mutation and Selection in the Vertebrate Non-coding Genome

    Author : Mikael Brandström; Hans Ellegren; Diethard Tautz; Uppsala universitet; []
    Keywords : Biology; non-coding genome; selection; mutation; chicken; human; indel; microsatellite; sequence alignment; comparative genomics; bioinformatics; vertebrate; Biologi;

    Abstract : The majority of the vertebrate genome sequence is not coding for proteins. In recent years, the evolution of this noncoding fraction of the genome has gained interest. These studies have been greatly facilitated by the availability of full genome sequences. READ MORE

  3. 3. Evolution of Vertebrate Eyes: a study on lens suspension and optical proterties

    Author : Ola Gustafsson; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; evolution; eye; fish; crystalline lens; lens suspension; multifocal optical systems; Agnatha; Actinopterygii; Chondrichthyes; Vertebrate; Sarcopterygii;

    Abstract : Many fishes have well-developed visual systems with color vision capabilities. The crystalline lens is the major refractive element in a fish eye since the cornea is optically inactive underwater. A typical fish eye has a large pupil and a lens of short focal length, features that increase light gathering ability. READ MORE

  4. 4. Evolutionary and Pharmacological Studies of NPY and QRFP Receptors

    Author : Bo Xu; Dan Larhammar; Samuel Svensson; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; NATURAL SCIENCES; MEDICAL AND HEALTH SCIENCES; Neuropeptide Y; genome duplication; Evolution; vertebrate; Pharmacology; Modelling; Kinetics; Bioinformatik; Bioinformatics; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik; Biologi med inriktning mot evolutionär funktionsgenomik; Biology with specialization in Evolutionary Functional Genomics; Farmaceutisk farmakologi; Pharmaceutical Pharmacology;

    Abstract : The neuropeptide Y (NPY) system consists of 3-4 peptides and 4-7 receptors in vertebrates. It has powerful effects on appetite regulation and is involved in many other biological processes including blood pressure regulation, bone formation and anxiety. READ MORE

  5. 5. Phylogenomic Analysis of Vertebrate Evolution

    Author : Björn Hallström; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; mammals; phyogenetics; phylogenomics; vertebrates; evolution;

    Abstract : The field of phylogenomics has emerged during the last five years, as the number of fully or partially sequenced genomes has increased rapidly. Using whole genomes for phylogenetic studies greatly increases the accuracy of the trees determined, and can potentially resolve phylogenetic questions that could not be resolved bu studies using only a few gene sequences.
