    Abstract : Responses of mountain birch growth to changed environmental conditions arestrongly affected by birch genotype, and nitrogen economy is a key factor influencingthe winter survival of first-year seedlings. These are some of the findings of a series ofstudies, in which growth, nitrogen economy and winter survival were analysed usingpot-grown seedlings of mountain birch (Betula pubescens ssp. READ MORE

  2. 2. Sphagnum limits Physiology, morphology and climate

  5. 5. Fuel and fly: adaptations to endurance exercise in migrating birds

    University dissertation from Department of Ecology, Lund University

    Author : Anders Kvist; Lund University.; Lunds universitet.; [2001]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; water balance; flight power; phenotypic flexibility; energy assimilation; basal metabolism; Animal ecology; Djurekologi;

    Abstract : Birds on migration alternate between consuming fuel stores during flights and accumulating fuel stores during stopovers. This thesis highlights some of the ways in which migrating birds have adapted to the different demands of fuelling and flight. Most of the time on migration is spent at stopover sites accumulating fuel stores. READ MORE
