  1. 1. The dispersal–vicariance pendulum and butterfly biogeography

    Författare :Ullasa Kodandaramaiah; Niklas Wahlberg; Brett Riddle; Stockholms universitet; []
    Nyckelord :Junonia; Coenonympha; Coenonymphina; Mycalesina; historical biogeography; vicariance; dispersal; DIVA; NATURAL SCIENCES; NATURVETENSKAP; zoologisk ekologi; Animal Ecology;

    Sammanfattning : The relative importance of dispersal and vicariance in speciation is a subject of long standing debate. The earliest historical biogeographers invoked dispersal to explain disjunct distributions. LÄS MER

  3. 2. Babblers, Biogeography and Bayesian Reasoning

    Författare :Magnus Gelang; Per Ericson; Per Alström; Isabel Sanmartín Bastida; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Africa; Asia; Bayesian inference; biogeography; Cettidae; dispersal; extinction; Middle East; persistence; Sylvioidea; Sylviidae; Timaliidae; vicariance; Systematic Zoology; zoologisk systematik och evolutionsforskning;

    Sammanfattning : In this thesis, I try to proceed one step further towards an understanding of the biogeographic processes forming the distribution patterns of organisms that we see today. Babblers and warblers are diverse groups of passerines that are phylogenetically intermixed with other groups in the superfamily Sylvioidea. LÄS MER

  4. 3. Diversification on an ancient Darwinian island : Evolutionary history of caddisflies (Trichoptera) and other organisms on New Caledonia

    Författare :Marianne Espeland; Kjell Arne Johanson; Niklas Wahlberg; Michael Balke; Stockholms universitet; []
    Nyckelord :New Caledonia; Trichoptera; island; biogeography; phylogenetics; DNA; dispersal; vicariance; adaptation; ultramafic; diversification; new species; environmental factors; Systematic Zoology; zoologisk systematik och evolutionsforskning;

    Sammanfattning : Islands are either of continental or oceanic origin, and the biota of such islands are a result of vicariance and dispersal, respectively. New Caledonia, in the South Pacific, is a part of former Gondwana, but the origin of its biota is heavily debated. LÄS MER

  7. 5. Tracing History : Phylogenetic, Taxonomic, and Biogeographic Research in the Colchicum Family

    Författare :Annika Vinnersten; Kåre Bremer; Bertil Nordenstam; Jerrold I Davis; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; biogeography; Colchicaceae; colchicine; dating; phylogeny; taxonomy; Biologi; Biology; Biologi;

    Sammanfattning : This thesis concerns the history and the intrafamilial delimitations of the plant family Colchicaceae. A phylogeny of 73 taxa representing all genera of Colchicaceae, except the monotypic Kuntheria, is presented. LÄS MER
