  1. 1. Physiological trade-offs in reproduction and condition dependence of a secondary sexual trait

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Måns S. Andersson; Uppsala universitet.; [2001]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Trade-offs; life history; immune ecology; cost of reproduction; costs of immune response; sexual selection; migration; moult; Newcastle disease; HbA1C; Ficedula albicollis; Utvecklingsbiologi; NATURAL SCIENCES Biology Organism biology Developmental biology; NATURVETENSKAP Biologi Organismbiologi Utvecklingsbiologi; Animal Ecology; zooekologi;

    Abstract : This thesis examines parental condition, how it is traded off against reproduction and how it is displayed in a secondary sexual trait. The studies were performed on nest-box breeding collared flycatchers Ficedula albicollis on the island of Gotland, in the Baltic Sea. READ MORE

  2. 2. Costs and benefits of immune system activation on physiology, behavior and offspring phenotype from an immunoecological perspective

    University dissertation from Department of Biology, Lund University

    Abstract : Popular Abstract in Swedish Djur och människor exponeras hela tiden för virus, bakterier och andra parasiter. Många av dessa virus och bakterier är ofarliga, medan andra orsakar infektioner och gör oss sjuka. När ett djur smittas av t.ex. READ MORE

  3. 3. Mechanisms and Biological Costs of Bacterial Resistance to Antimicrobial Peptides

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Hava Lofton Tomenius; Uppsala universitet.; [2016]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; antimicrobial peptides; antibiotic resistance; fitness cost; Salmonella Typhimurium; Staphylococcus aureus; bile; serum; pH response; growth rate; mice; phoP; pmrB; waaY; LPS; LL-37; defensins; membrane potential; Mikrobiologi; Microbiology;

    Abstract : The global increasing problem of antibiotic resistance necessarily drives the pursuit and discovery of new antimicrobial agents. Antimicrobial peptides (AMPs) initially seemed like promising new drug candidates. Already members of the innate immune system, it was assumed that they would be bioactive and non-toxic. READ MORE

  4. 4. Costs in the ecology and evolution of the vertebrate immune system

    University dissertation from Lars Råberg, Ecology Building, S-223 62 Lund

    Author : Lars Råberg; Lunds universitet.; Lund University.; [2002]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cost of resistance; ecological immunology; immunocompetence; Parus caeruleus; transgenic mice; Animal ecology; Djurekologi; blue tit; basal metabolic rate;

    Abstract : Popular Abstract in Swedish Trots att vi har ett mycket sofistikerat immunförsvar är infektionssjukdomar ett stort problem för alla flercelliga organismer. Varför har vi inte under evolutionens gång lyckats finna ett sätt att överlista virus, bakterier och andra parasiter? En förklaring är att immunförsvaret är kostsamt, dvs att ett kraftfullt immunförsvar inte bara ger fördelar i form av ökat skydd mot parasiter, utan också någon form av nackdelar. READ MORE

  5. 5. Development of vaccines and mouse models for chronic hepatitis C virus infection

    University dissertation from Stockholm : Karolinska Institutet, Dept of Laboratory Medicine

    Author : Sepideh Levander; Karolinska Institutet.; Karolinska Institutet.; [2016]
