  1. 1. Desert Plants and Deserted Islands : Systematics and Ethnobotany in Caryophyllaceae

    Författare :Anneleen Kool; Mats Thulin; Gudrun Kadereit; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; BEAST; Corrigiola; DNA barcoding; Morocco; Pollichia; Polycarpon; Polycarpaea; RAxML; Sanctambrosia; Spergula; Spergularia; Sphaerocoma;

    Sammanfattning : Background. Caryophyllaceae is a large and cosmopolitic flowering plant family, however the systematics of many of its basal groups has been unclear, due to a lack of unambiguous morphology. Some members of Caryophyllaceae are used medicinally, e.g. LÄS MER

  2. 2. Botanical Repellents and Pesticides Traditionally Used Against Haematophagous Invertebrates in Lao PDR

    Författare :Chanda Vongsombath; Thomas Jaenson; Raimondas Mozuraitis; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Ethnobotany; fly larvae; Lao PDR; medical entomology; mosquito repellents; myiasis; plant-based insecticides; terrestrial leeches; Haemadipsidae; Systematics and phylogenetics; Systematik och fylogeni; Organism biology; Organismbiologi; Biologi med inriktning mot systematik; Biology with specialization in Systematics;

    Sammanfattning : Haematophagous parasites and disease vectors such as leeches, ticks, mites, lice, bed bugs, mosquitoes, and myiasis-causing fly larvae are common health problems in Lao Peoples Democratic Republic (Lao PDR). A main aim of my field work in Lao PDR in 2006-2010 was to document traditional knowledge among different ethnic groups about plants that people use to repel or to kill blood-feeding invertebrates.

  3. 3. Aspects of carnivoran evolution in Africa

    Författare :Reihaneh Dehghani; Lars Werdelin; Philippe Gaubert; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Carnivora; Evolution; Africa; Viverridae; Herpestidae; Systematics and phylogenetics; Systematik och fylogeni; Systematic Zoology; systematisk zoologi;

    Sammanfattning : This thesis concerns the evolution of African small carnivorans, with emphasis on East African Viverridae and Herpestidae (Carnivora, Mammalia). Viverridae and Herpestidae are two Old World feliform (belonging to the cat branch) carnivoran families with a confusing, and sometimes even misleading, taxonomic and systematic history, in addition to a scarce fossil record.

  4. 4. Molecular phylogenetics and taxonomic issues in dragonfly systematics (Insecta: Odonata)

    Författare :Rasmus Hovmöller; Thomas Pape; Mari Källersjö; Kjell Arne Johanson; Karl Kjer; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Systematics and phylogenetics; Systematik och fylogeni;

    Sammanfattning : Dragonflies (Odonata) are one of the ancestral groups of extant insects. They represent one of the three most basal branches in the phylogeny of winged insects. The other two groups are the Ephemeroptera, mayflies, and Neoptera, the latter which covers the remaining winged insects. LÄS MER

  5. 5. Contributions to the understanding of diversity and evolution in the genus Coreomyces

    Författare :Henrik Sundberg; Stefan Ekman; Åsa Kruys; Donald H. Pfister; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; ascomycetes; Coreomyces; Corixidae. DNA; DNA extraction; Fungi; ge-nome; host specificity; Laboulbeniales; mating types; MAT-loci; meth-odology; NGS; parasite; position specificity; systematics; taxonomy; Biology with specialization in Systematics; Biologi med inriktning mot systematik; Biology with specialization in Evolutionary Organismal Biology; Biologi med inriktning mot evolutionär organismbiologi;

    Sammanfattning : The Laboulbeniales is an order of enigmatic ascomycete fungi that are obligate microscopic parasites of arthropods, which are usually non-detrimental. They typically display a high degree of host specificity, and the genus Coreomyces, which is the recurring theme of this thesis, is no exception. LÄS MER
