  4. 2. Novel approaches in modeling of soil carbon : Upscaling theories and energetics

    Author : Arjun Chakrawal; Stefano Manzoni; Hyun-Seob Song; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Microorganisms; soil C cycling; spatial heterogeneity; energetics; thermodynamics; microbial metabolism; calorespirometric ratio; microbial traits; heat dissipation; microscale; Physical Geography; naturgeografi;

    Abstract : Soils contain more carbon (C) than terrestrial (above ground) and atmospheric carbon combined. Mismanagement of soil C could lead to increased greenhouse gas emissions, whereas practices leading to increased C storage would help mitigate climate change while improving soil fertility and ecological functions.

  5. 3. Water in and on ionic materials : Structure, energetics, and vibrations

    Author : Getachew Kebede; Kersti Hermansson; Marie-Pierre Gaigeot; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; DFT; dispersion interactions; OH stretching frequency; electric field; dipole moment; Hydrogen bond; ionic surfaces; ionic hydrates;

    Abstract : Many chemical and physical phenomena in nature, in industrial processes, and in our daily lives take place at water/solid interfaces. The aim of this thesis is to further our knowledge of such processes at a molecular level. READ MORE

  6. 4. Bird orientation: external cues and ecological factors

    Author : Johan Bäckman; Evolutionär ekologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; tracking radar; Emlen funnel.; Animal ecology; Djurekologi; oscillatory orientation; roosting flight; scatter; concentration; heading; cue calibration; light dependent; magnetoreception; subcutaneous fat stores; body condition; energetics; geomagnetic field; visual cues; orientation; birds; migration;

    Abstract : Birds are generally capable of accurate orientation. In this thesis I present studies about the external cues and the ecological factors that influences bird orientation. A multitude of environmental cues are used to select and maintain a proper direction. READ MORE

  7. 5. Costs, benefits and constraints in the evolution of avian reproductive tactics: a study on the blue tit

    Author : Erik Svensson; Evolutionär ekologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; reproductive timing; selection analysis; natural selection; mate quality; nestlings; sex ratio; DNA-content; flow cytometry; ELISA; BMR; energetics; immunocompetence; immune system; sexual conflict; nestling mortality; thermoregulation; moult; reproductive costs; reproductive effort; Parus caeruleus; blue tit; birds; juvenile survival; laying date; food supply; Animal ecology; Djurekologi;

    Abstract : In this study I have investigated the various factors influencing reproductive tactics among breeding blue tits (Parus caeruleus). The study was carried out in a nestbox-breeding population of marked individuals at the Revinge Area, outside Lund, southern Sweden. READ MORE
