  1. 1. Avian Malaria and Related Blood Parasites: Molecular Diversity, Ecology and Evolution

    Författare :Olof Hellgren; MEMEG; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; diversity; Plasmodium; bird-migration; transmission; blackfly; host-specificity; host-preference; cytochrome b; DHFR-TS; recombination; phylogeny; Ecology; Ekologi; Genetics; cytogenetics; Genetik; cytogenetik; Parasitology human and animal ; Haemoproteus; Leucocytozoon; Parasitologi människa och djur ; Animal ecology; Djurekologi; Natural science; Naturvetenskap;

    Sammanfattning : Malaria-like parasites consist of a large group of species that infects primates, rodents, bats, lizard and birds. I have focused on parasites from the genera Haemoproteus, Plasmodium and Leucocytozoon that are infecting birds. LÄS MER

  3. 2. Odour-mediated host preference in mosquitoes: the role of the maxillary palps in host recognition

    Författare :Shahid Majeed; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The mechanisms underlying host preference in mosquitoes are ultimately a result of optimal foraging on currently available hosts and historical patterns of host availability. The proximate mechanisms are regulated by available host cues and the nature of the mosquitoes’ responses to these cues. LÄS MER

  4. 3. An evolutionary view of the taxonomy and ecology of Inocybe (Agaricales) with new perspectives gleaned from GenBank metadata

    Författare :Martin Ryberg; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Inocybe; Inocybaceae; emerencia; GenBank; Insufficiently identified sequences IIS ;

    Sammanfattning : Inocybe (Inocybaceae) is one of the most speciose genera among the gilled mushrooms (Agaricales) but large parts of its taxonomy and evolutionary history remain poorly explored. The present thesis sho... LÄS MER

  5. 4. The role of Assortative Mating in the Initial Stages of Sympatric and Parapatric Speciation

    Författare :Emma Rova; Mats Björklund; Göran Arnqvist; James Mallet; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Callosobruchus maculatus; host fidelity; assortative mating; inbreeding; experimental evidence; sympatric speciation; parapatric speciation; Biology; Biologi; Biologi med inriktning mot zooekologi; Biology with specialization in Animal Ecology;

    Sammanfattning : Divergence in the face of gene flow is perhaps the most wildly disputed subject among researchers through time. The debate is an old one and we find its origin as far back as the era of Darwin. LÄS MER

  7. 5. Host-pathogen interactions in root infecting oomycete species

    Författare :Sara Hosseini; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : The oomycetes include some of the most devastating pathogens on both cultivated crops and wild plants. In the genus Phytophthora some closely related species have a broad host range, while others are very host specific. LÄS MER
