  1. 1. 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. 2. Speciation - What Can be Learned from a Flycatcher Hybrid Zone?

    Författare :Chris Wiley; Anna Qvarnström; Lars Gustafsson; Roger Butlin; Uppsala universitet; []
    Nyckelord :Biology; speciation; reinforcement; fitness; postzygotic isolation; asymmetrical hybridization; hybrid zone; species recognition; mate choice; sexual selection; direct benefits; parasite resistance; delayed plumage maturation; Ficedula hypoleuca; Ficedula albicollis; flycatcher; Biologi;

    Sammanfattning : Studies of hybrid zones offer important insights into the process of speciation. Much of the knowledge to be gained is dependent on an accurate estimation of the strength of pre- and post-zygotic isolation between hybridizing taxa. My results demonstrate that hybridization can variously affect different components of fitness. LÄS MER

  4. 3. Non-Energy Benefits of Industrial Energy Efficiency : Roles and Potentials

    Författare :Therese Nehler; Patrik Thollander; Mats Söderström; Erik Dahlquist; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Climate and environmental targets place significant requirements on energy efficiency and improved industrial energy efficiency is viewed as one of the most important means of reducing CO2 emissions and mitigating climate change. Even though efforts have been undertaken to improve energy efficiency there is still the potential for further improvements to be made. LÄS MER

  5. 4. Financial benefits of shop floor productivity improvements

    Författare :Robin Sundkvist; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Productivity; Cash flow; Manufacturing;

    Sammanfattning : The prevailing situation in the global economy calls for innovative productivity investment approaches aiming to prevent further labour force reductions and to restore manufacturers’ competitiveness. The purpose of this research initiative has been to motivate production managers to invest in productivity improvements by establishing a framework that explains how shop floor productivity improvements provide financial benefits.
