  1. 1. Avian Malaria infection and its effect on cellular metabolic rate in Ficedula Flycatchers

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning; Uppsala universitet/Institutionen för cell- och molekylärbiologi

    Author : Nader Ibrahim; [2022]
    Keywords : ;

    Abstract : Chronic avian malaria and low-intensity parasite infections can have a negative influence on reproduction and survival which can reduce the fitness of the host. Therefore, the effect on host due to avian malaria infection can affect a bird’s lifespan. Consequently, avian parasites can influence evolution, physiology, and host morphology. READ MORE

  3. 2. Malaria infected male collared flycatchers, Ficedula albicollis experience higher reproductive success and tend to have larger sexual ornaments

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : William Jones; [2016]
    Keywords : Ficedula; Avian malaria; sexual selection;

    Abstract : How parasites influence the population dynamics of their hosts depends on 1) theproportion of individuals that carry the infection in the population, 2) what type of individuals aremost susceptible to infection and 3) the fitness effects of infection. In this study I first investigate thefrequency of malaria strains transmitted in the African winter quarters or at the European breedinggrounds in collared flycatchers (Ficedula albicollis).

  4. 3. Malaria infection in relation to reproductive success and secondary sexual traits in collared flycatcher : In new and old breeding areas

    University essay from Mittuniversitetet/Avdelningen för naturvetenskap

    Author : Ye Xiong; [2014]
    Keywords : ;

    Abstract : Life-history theory is based on the idea that every individual face a limitation of energy, nutrients and time in its lifespan. This optimization problem is resulting in trade-offs between resource demanding tasks and traits. READ MORE

  5. 4. Avian malaria in collared flycatchers : fitness consequences and a relation to a secondary sexual character

    University essay from Zooekologi; Institutionen för biologisk grundutbildning

    Author : Eric Blomgren; [2011]
    Keywords : ;

    Abstract : All organisms have limited amounts of energy, time and nutrients to spend during their lifetime and this gives rise to trade-offs in life histories. It has been shown that increased reproductive effort can reduce parasite resistance and specific immune response in birds. READ MORE
