  1. 1. Babblers, Biogeography and Bayesian Reasoning

    University dissertation from Stockholm : Department of Zoology, Stockholm University

    Author : Magnus Gelang; Stockholms universitet.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Africa; Asia; Bayesian inference; biogeography; Cettidae; dispersal; extinction; Middle East; persistence; Sylvioidea; Sylviidae; Timaliidae; vicariance; Systematic Zoology; zoologisk systematik och evolutionsforskning;

    Abstract : 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. READ MORE

  3. 3. Diversity Underfoot Systematics and Biogeography of the Dictyostelid Social Amoebae

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Allison L Perrigo; Uppsala universitet.; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Amoeba; biogeography; cryptic species; dictyostelid; latitudinal gradient; multicellularity; protist; social amoeba; phylogenetics; systematics; new species; Biologi med inriktning mot systematik; Biology with specialization in Systematics;

    Abstract : Dictyostelids (Amoebozoa) are a group of social amoebae consisting of approximately 150 species, which are found in terrestrial habitats worldwide. They are divided into eight major clades based on molecular phylogeny, and within these clades are many species complexes. READ MORE

  4. 4. Factors influencing the biogeography of bacteria in fresh waters - a metacommunity approach

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Jürg Brendan Logue; Uppsala universitet.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bacteria; diversity; richness; community composition; dispersal; metacommunity; fresh water; biogeography; NATURAL SCIENCES Biology Terrestrial; freshwater and marine ecology Freshwater ecology; NATURVETENSKAP Biologi Terrestrisk; limnisk och marin ekologi Limnisk ekologi; MEDICINE Microbiology; immunology; infectious diseases Microbiology; MEDICIN Mikrobiologi; immunologi; infektionssjukdomar Mikrobiologi; Biologi med inriktning mot limnologi; Biology with specialization in Limnology;

    Abstract : One of ecology’s primary goals is to comprehend biodiversity and its patterns of distribution over space and time. Since microorganisms play a pivotal role in key ecological processes, the diversity of microbial communities may have important implications for the stability and functioning of Earth’s ecosystems.

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

    University dissertation from Stockholm : Department of Zoology, Stockholm University

    Author : Ullasa Kodandaramaiah; Stockholms universitet.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Junonia; Coenonympha; Coenonymphina; Mycalesina; historical biogeography; vicariance; dispersal; DIVA; NATURAL SCIENCES; NATURVETENSKAP; Animal Ecology; zoologisk ekologi;

    Abstract : 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. READ MORE
