  1. 6. Sexual selection in the collared flycatcher (Ficedula albicollis) : A life-history perspective

    Författare :Anna Qvarnström; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ecology; Sexual selection; life-history; honest signalling; fighting ability; genotype-environment interaction; direct benefits; indirect benefits; Ekologi; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi; Animal Ecology; zooekologi;

    Sammanfattning : This thesis integrates sexual selection theory with life history theory to elucidate the causes and consequences of variation in a male secondary sexual trait. The model organism, the collared flycatcher (Ficedula albicollis), was studied on Gotland, Sweden. LÄS MER

  3. 7. Causes and consequences of life-history variation : The effects of parasites, glucocorticoids, and environmental conditions in the collared flycatcher (Ficedula albicollis)

    Författare :Kevin Fletcher; Lars Gustafsson; Anders Pape Moller; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Collard flycatcher; Haemosporidian blood parasite; glucocorticoid; life history;

    Sammanfattning : Life-history is the study of all the different stages of life that affect reproductive success and survival between the birth and death of an organism. The reproductive output of an organism is constrained by many things including time, resource, disease agents and environmental conditions. LÄS MER

  4. 8. Sources of variability in heterospecific social information use for breeding habitat selection : Role of genetics and personality in collared flycatchers

    Författare :Jennifer Morinay; Blandine Doligez; Lars Gustafsson; Rachel Kendal; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Heterospecific social information; personality; aggressiveness; nest site choice; within- and between-individual variability; quantitative genetics; experimental approaches in the wild; collared flycatchers;

    Sammanfattning : All their life, individuals have to make decisions that may strongly affect their fitness. To optimize their decisions, they can use personally acquired information but also information obtained from observing other individuals (“social information”). LÄS MER

  7. 10. 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
