  2. 1. Species Limits and Systematics in Some Passerine Birds

    Author : Per Alström; Timothy M. Crowe; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organismic biology; Mirafra; Seicercus; Phylloscopus; Motacilla; species concepts; species limits; phylogeny; morphology; vocalisations; mitochondrial DNA; nuclear DNA; incongruence; Organismbiologi; Organism biology; Organismbiologi; systematisk zoologi; Systematic Zoology;

    Abstract : I use morphological, vocal, molecular, behavioural, ecological and distributional data to re-evaluate the systematics of three passerine bird groups, the Mirafraassamica complex (bush-larks), the genus Seicercus ("spectacled-warblers"; with emphasis on the the S. burkii complex) and the genus Motacilla (wagtails).

  4. 2. Systematics of Eucoilini : Exploring the diversity of a poorly known group of Cynipoid parasitic wasps

    Author : Mattias Forshage; Fredrik Ronquist; Göran Nordlander; John Heraty; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Eucoila; Trybliographa; Eucoilini; Eucoilinae; Figitidae; Cynipoidea; Hymenoptera; phylogenetics; diagnostics; classification; taxonomy; systematic revision; morphology; Systematics and phylogenetics; Systematik och fylogeni; Entomology; entomologi; systematisk zoologi; Systematic Zoology;

    Abstract : Many animal species are still undiscovered, even in Sweden. This thesis deals with the wasps of the subfamily Eucoilinae (of Figitidae, Cynipoidea), a poorly known group of small parasitoids of Dipteran flies. 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. Phylogenetic Studies in the Euasterids II : with Particular Reference to Asterales and Escalloniaceae

    Author : Johannes Lundberg; Olof Ryding; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organismic biology; Organismbiologi; Organism biology; Organismbiologi; systematisk botanik; Systematic Botany;

    Abstract : The present study is concerned with the evolutionary relationships among the Euasterids II, a group of angiosperms that includes the orders Apiales, Aquifoliales, Asterales, and Dipsacales together with several small, poorly known families yet unplaced as to order.Parsimony analysis of nucleotide sequence data from the chloroplast genes atpB, ndhF and rbcL together with morphological data are used to construct a phylogeny of the order Asterals, which in the present sense includes 11 families and more than 26 000 species.

  7. 5. Systematics of Echiochilon and Ogastemma (Boraginaceae), and the Phylogeny of Boraginoideae

    Author : Elisabeth Långström; Per Ola Karis; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organismic biology; Antiphytum; Echiochilon; Ogastemma; Boraginaceae; Echiochileae trib. nov.; phylogeny; ITS; floral morphology; atpB; tribes; biogeography; Africa; America; Organismbiologi; Organism biology; Organismbiologi; Systematisk botanik; Systematic Botany;

    Abstract : Echiochilon, Ogastemma and Sericostoma are revised resulting in the recognition of 15 species of Echiochilon and one Ogastemma species. Several species are placed in synonymy and three new species are described, E. baricum, E. callianthum and E. READ MORE
