  1. 1. Avian Malaria and Interspecific Interactions in Ficedula Flycatchers

    Författare :William Jones; Anna Qvarnström; Rebecca Safran; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ficedula; flycatcher; avian malaria; Biologi med inriktning mot zooekologi; Biology with specialization in Animal Ecology;

    Sammanfattning : Parasitism is a core theme in ecological and evolutionary studies. Despite this, there are still gaps in our knowledge regarding host-parasite interactions in nature. LÄS MER

  3. 2. Intra-specific variation in avian malaria : Linking infection dynamics to haplotypes

    Författare :Victor Kalbskopf; MEMEG; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; avian malaria; phyogenetics; population genetics; evolution;

    Sammanfattning : Avian Malaria infects thousands of species of birds across the Aves class. The most widespread (geographically and phylogenetically)morphological species is Plasmodium relictum, and of that, the mitochondrial lineage of SGS1 is the most common and invasive. LÄS MER

  4. 3. LIVING WITH PARASITES: AVIAN MALARIA, TELOMERE LENGTH AND LIFE HISTORY TRADE-OFFS

    Författare :Asghar Muhammad; MEMEG; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Avian malaria; Plasmodium; qPCR; parasitemia; life history; reproduction; survival; feather growth; MHC; telomere length; heritability; telomere loss; fitness; wild population; Acrocephalus arundinaceus; Delichon urbica;

    Sammanfattning : Haemosporidia is a well-studied group of parasites, which infect mammals, reptiles and birds and use blood sucking vectors for their transmission. By conducting natural population studies and experimental infections, We have been able to detect and quantify Haemosporidia from avian blood to investigate how these pathogens affect their avian hosts.

  5. 4. Avian MHC: variation and selection in the wild

    Författare :Helena Westerdahl; MEMEG; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; polymorphism; balancing selection; cDNA; avian malaria; great reed warbler; Djurekologi; bird; Animal ecology; immune defence; MHC class II; Major Histocompatibility Complex; MHC class I;

    Sammanfattning : In vertebrates the Major Histocompatibility Complex (MHC) plays a central role in the specific immune defence against various pathogens. Compared with other coding genes the MHC genes exhibit an extremely high level of polymorphism that is maintained by balancing selection. LÄS MER

  7. 5. Evolutionary genomics of host-microbe interactions

    Författare :Elin Videvall; MEMEG; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; host; microbiota; avian malaria; ostrich; parasite; dual RNA-seq;

    Sammanfattning : The microbes living inside hosts have highly important consequences for host health and fitness. From the host’s perspective, some microbes exhibit mutualistic tendencies, others parasitic, and some commensal, but this is context-dependent and opportunistic lifestyles are widespread in nature.
