  1. 1. Patterns and Processes of Evolution in Sundaland

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Robert-Jan den Tex; Uppsala universitet.; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES Biology; NATURVETENSKAP Biologi; NATURAL SCIENCES Biology Organism biology Systematics and phylogenetics; NATURVETENSKAP Biologi Organismbiologi Systematik och fylogeni; NATURAL SCIENCES Biology Cell and molecular biology Genetics; NATURVETENSKAP Biologi Cell- och molekylärbiologi Genetik; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Sammanfattning : Biodiversity in the tropics is disproportionately high compared to other habitats, and also under disproportionate threat from human impact. It is necessary to understand how this diversity evolved and how it is partitioned across space in order to preserve it. LÄS MER

  2. 2. Evolution and biodiversity of the Ixoroideae (Rubiaceae)

    Detta är en avhandling från Stockholm : Department of Botany, Stockholm University

    Författare :Kent Kainulainen; Stockholms universitet.; [2010]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Alberteae; character evolution; classification; Condamineeae; fruit evolution; Ixoroideae; phylogenetics; pollen presentation; Rubiaceae; systematics; taxonomy; NATURAL SCIENCES Biology Organism biology Systematics and phylogenetics; NATURVETENSKAP Biologi Organismbiologi Systematik och fylogeni; Plant Systematics; växtsystematik;

    Sammanfattning : The phylogenetic relationships within subfamily Ixoroideae of the coffee family are investigated by phylogenetic reconstruction of molecular data, including regions of the chloroplast DNA (matK, ndhF, rbcL, rps16, trnH-psbA, trnS-G, and trnT-F), and the nuclear ribosomal DNA (ITS). The evolution of morphological characters within the group are inferred, with focus on characters used in classification. LÄS MER

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Amomum; Zingiberaceae; Flore du Cambodge du Laos et du Vietnam; Taxonomy; Ethnobotany; Postpartum; Mother roasting; Hotbed; Brou; Saek; Kry; Lao PDR; NATURAL SCIENCES Biology Organism biology; NATURVETENSKAP Biologi Organismbiologi; NATURAL SCIENCES Biology Organism biology Systematics and phylogenetics; NATURVETENSKAP Biologi Organismbiologi Systematik och fylogeni; Biologi med inriktning mot systematik; Biology with specialization in Systematics;

    Sammanfattning : The species of Amomum Roxb. (Zingiberaceae) in Cambodia, Laos and Vietnam are revised. Thirty-five species and two varieties are recognised, all names are typified, and detailed descriptions and a key are provided. Nine new species are described and one species is validated. LÄS MER

  4. 4. Systematics and polyploid evolution in Potentilleae (Rosaceae)

    Detta är en avhandling från Stockholm : Department of Botany, Stockholm University

    Författare :Magnus Lundberg; Stockholms universitet.; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Potentilleae; Fragariinae; Potentilla; Sibbaldia; Fragaria; Alchemilla; systematics; phylogeny; polyploidy; autopolyploidy; allopolyploidy; reticulate evolution; NATURAL SCIENCES Biology Organism biology Systematics and phylogenetics; NATURVETENSKAP Biologi Organismbiologi Systematik och fylogeni; Plant Systematics; växtsystematik;

    Sammanfattning : This thesis comprises studies of the phylogenetic relationships in the flowering plant clade Potentilleae in Rosaceae. The relationships were elucidated by using DNA sequence data from the nuclear genome as well as from the plastid genome. In particular, the focus of the studies was the investigation of allopolyploidy, i.e. LÄS MER
