  2. 1. Taxonomy and Reticulate Phylogeny of Heliosperma and Related Genera (Sileneae, Caryophyllaceae)

    Author : Božo Frajman; Bengt Oxelman; Mats Thulin; Christian Brochmann; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sileneae; Silene; Heliosperma; Atocion; Viscaria; taxonomy; phylogenetics; relative dating; reticulate evolution; chloroplast capture; homoploid hybridisation; BEAST; r8s; PATHd8; Prometheus; RPA2; RPB2; RPD2a; RPD2b; Balkan Peninsula; endemics; Systematics and phylogenetics; Systematik och fylogeni;

    Abstract : Heliosperma (nom. cons prop.) comprises 15—20 taxa, most of them endemic to the Balkan Peninsula. DNA sequences from the chloroplast (rps16 intron, psbE-petG spacer) and the nuclear genome (ITS and four putatively unlinked RNA polymerase genes) are used to elucidate phylogenetic relationships within Heliosperma, and its position within Sileneae.

  4. 2. Phylogeography of the Adder, Vipera berus

    Author : Martin Carlsson; Håkan Tegelström; Michael Douglas; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; Phylogeography; Vipera; adders; mtDNA; microsatellites; RAPDs; Genetik; Clinical genetics; Klinisk genetik; Genetics; genetik;

    Abstract : The phylogeography of a wide ranging temperate species, the adder, Vipera berus, was investigated using several genetic tools, with special emphasis on the post-glacial colonisation pattern of Fennoscandia. The area was colonised from two directions by adder populations representing different glacial refugia. READ MORE

    Abstract : In this thesis I will compare and contrast the two willow warbler subspecies (Phylloscopus trochilus trochilus and P. t. acredula) with differing migratory phenotypes (or "migratype") in the context of their migratory divide and hybrid zone in central Sweden. Their migratory programs differ in the direction and distance traveled during migration. READ MORE
