  1. 1. Avian thermoregulation across age and seasons

    Författare :Fredrik Andreasson; Evolutionär ekologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ambient temperature; body temperature; Cyanistes caeruleus; energy expenditure; hypothermia; life-history theory; metabolic rate; Parus major; thermoregulation; trade-off; winter ecology;

    Sammanfattning : Animals constantly need to relate to prevailing environmental conditions and regulate their body temperature accordingly. Body temperature regulation in birds and mammals is inherently linked to energy expenditure and, thus, thermoregulation is a physiological mechanism that could trade-off with other costly processes, with potential long-term fitness consequences.

  3. 2. The effects of temperature on avian physiology, behavior and development

    Författare :Andreas Nord; Evolutionär ekologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; clutch size; Cyanistes caeruleus; ecological immunology; energy expenditure; fever; Ficedula hypoleuca; heterothermy; hypothermia; incubation; life history; metabolic rate; Parus major; RMR; Taeniopygia guttata; temperature; winter;

    Sammanfattning : Temperature is a property of profound matter in all aspects of animal life, affecting both individual energy budgets and the environments in which animals reside. Thus, a proper understanding of the effects of temperature variation is instrumental in understanding not only animal form and function, but also the structure and dynamics of wild populations.

  4. 3. Protection against cold in prehospital trauma care

    Författare :Otto Henriksson; Ulf Björnstig; Tore Vikström; Peter Naredi; Hannu Rintamäki; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hypothermia; prehospital trauma care; emergency medical services; passive warming; thermal insulation; heat loss; body temperature regulation; kirurgi; Surgery;

    Sammanfattning : Background: Protection against cold is vitally important in prehospital trauma care to reduce heat loss and prevent body core cooling. Objectives: Evaluate the effect on cold stress and thermoregulation in volunteer subjects byutilising additional insulation on a spineboard (I). LÄS MER

  5. 4. Milk production, fluid balance and temperature regulation in lactating camels (Camelus dromedarius)

    Författare :Tafesse Bekele; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : The aims of this thesis were to identify good milking and watering routines for camels, and to better understand the physiological mechanisms that enable camels to produce milk during long periods of water deprivation. Milk production was increased by changing the number of milkings from one to four times per day in an on-farm study. LÄS MER

  7. 5. Regulation and measurement of brown adipose tissue blood flow

    Författare :Gustavo Abreu-Vieira; Jan Nedergaard; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fysiologi; Physiology;

    Sammanfattning : Brown adipose tissue (BAT) is an organ specialized in macromolecule combustion in order to produce heat. Because of its high capacity to dissipate energy, it is currently among the best hopes for future treatments of obesity and diabetes. LÄS MER
