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

    Author : Kent Kainulainen; Birgitta Bremer; Sylvain Razafimandimbison; Torsten Eriksson; Sandra Knapp; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Alberteae; character evolution; classification; Condamineeae; fruit evolution; Ixoroideae; phylogenetics; pollen presentation; Rubiaceae; systematics; taxonomy; Systematics and phylogenetics; Systematik och fylogeni; växtsystematik; Plant Systematics;

    Abstract : 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. READ MORE

  5. 3. Evolutionary Studies in Asterids Emphasising Euasterids II

    Author : Jesper Kårehed; Mats H. G. Gustafsson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organismic biology; Apiales; Aquifoliales; Asterales; asterids; Bayesian inference; Cardiopteridaceae; DNA sequence data; Icacinaceae; morphology; parsimony; Pennantiaceae; phylogeny; Stemonuraceae; Organismbiologi; Organism biology; Organismbiologi; systematisk botanik; Systematic Botany;

    Abstract : This thesis deals with evolutionary relationships within the asterids, a group of plants comprising about one-third of all flowering plants.Two new families are recognised: Pennantiaceae and Stemonuraceae. The woody Pennantia from New Zealand and Australia is the sole genus of Pennantiaceae. READ MORE

  6. 4. Evolutionary history and chloroplast DNA variation in three plant genera: Betula, Corylus and Salix. : The impact of post-glacial colonisation and hybridisation

    Author : Anna Palmé; Andrew Lowe; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biology; chloroplast DNA; phylogeography; hybridization; phylogeny; Salix caprea; Betula pendula; Corylus avellana; Biologi; Biology; Biologi; naturvårdsbiologi; Conservation Biology;

    Abstract : The great difference in the level of chloroplast variation and its geographic structure among the three main species studied here demonstrates that forest species do not form a homogeneous group. Hazel shows a genetic structure similar to many other thermophilous species and this structure, in combination with fossil evidence, indicates that the post-glacial colonisation of most of Europe originated in a refugium in western France while the Balkan and Italy were colonised from a south-eastern refugium.

  7. 5. Building knowledge for a forage breeding program on native Festuca species in the highlands of Bolivia

    Author : Karina Rossio Ustariz Olivera; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Native grasses constitute the most important source of feed for camelids, sheep and cattle in the highlands of Bolivia, where the genus Festuca is one of the major feed components. The two most important species of this region are F. dolichophylla J. Presl (known as “chilliwa”) and F. READ MORE
