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

    Author : Olof Hellgren; MEMEG; []
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 2. Causes and consequences of blood parasite infections in birds

    Author : Martin Stjernman; Biodiversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Animal physiology; Djurfysiologi; Parasitologi människa och djur ; Parasitology human and animal ; maternal transfer; stabilising selection; parasite resistance; parasites; trade-off; cost of reproduction; Ficedula hypoleuca; pied flycatcher; Haemoproteus; blue tit; Parus caeruleus;

    Abstract : Parasites are ubiquitous and can cause significant fitness reductions to their hosts. Therefore, selection for the evolution of host resistance should be strong. However, resistance may be costly and should be traded-off against other fitness related traits. READ MORE

  5. 3. On the Effects of Blood Parasites in Wild Birds

    Author : Peter Halvarsson; Jacob Höglund; Staffan Bensch; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Atoxoplasma; avian malaria; coccidia; Gallinago media; Haemoproteus; Leucocytozoon; parasite prevalence; Passer montanus; Plasmodium; recapture mod-els; survival; Biologi med inriktning mot populationsbiologi; Biology with specialization in Population Biology;

    Abstract : Coccidian and haemoatozoan parasites are commonly occurring endo-parasites in wild birds and prevalence can vary among species and populations. In addition to prevalence studies, parasites are often used to investigate effects on life history traits. READ MORE

  6. 4. Diversity of avian haemosporidian parasites : Host specificity, genetic structure and infection patterns

    Author : Xi Huang; MEMEG; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Haemoproteus; Sequence capture; host specificity; quantitative PCR; phylogeny;

    Abstract : Parasites live on or inside their hosts and usually cause fitness loss, sometimes even lead to outbreaks of emerging infectious disease. Understanding how a parasite can infect its hosts (i.e., host specificity of the parasite) is important to both basic studies on disease evolution and the whole ecosystem health. READ MORE

  7. 5. Trade-offs between life history traits and immune defence in the collared flycatcher Ficedula albicollis

    Author : Dag Nordling; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ecology; Ekologi; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi; Animal Ecology; zooekologi;

    Abstract : This thesis examines the effects of reproductive effort on immune function and parasite resistance in breeding collared flycatchers, Ficedula albicollis. It also focuses on the role of the immune function in the trade-off between number and fitness of offspring. READ MORE
