  2. 6. Modelling Climate Policy – Trade-Off Metrics, Resource Markets, and Uncertainty

    Author : Daniel Johansson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; OPEC; GWP; energy; uncertainty; biomass; climate change; oil; land use; greenhouse gases; Kyoto Protocol;

    Abstract : This thesis consists of five papers related to climate change policy. In paper I andpaper II we discuss the use of Global Warming Potentials (GWPs) that facilitate the tradeoffbetween abatement of the different greenhouse gases (GHGs). READ MORE

  4. 7. Causes and consequences of blood parasite infections in birds

    Author : Martin Stjernman; Biodiversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Animal physiology; Djurfysiologi; Parasitologi människa och djur ; Parasitology human and animal ; maternal transfer; stabilising selection; parasite resistance; parasites; trade-off; cost of reproduction; Ficedula hypoleuca; pied flycatcher; Haemoproteus; blue tit; Parus caeruleus;

    Abstract : Parasites are ubiquitous and can cause significant fitness reductions to their hosts. Therefore, selection for the evolution of host resistance should be strong. However, resistance may be costly and should be traded-off against other fitness related traits. READ MORE

  5. 8. Avian thermoregulation across age and seasons

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

    Abstract : 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.

  6. 9. Age-specific trade-offs in life-history evolution

    Author : Martyna K. Zwoinska; Alexei Maklakov; Marjo Saastamoinen; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; life history; trade-off; learning; aging; sex differences; dispersal; Caenorhabditis; Drosophila; Biologi med inriktning mot zooekologi; Biology with specialization in Animal Ecology;

    Abstract : Trade-offs prevent selection from driving all fitness-enhancing traits towards values that would maximize fitness. Life-history trade-offs, such as the one between survival and reproduction are well-studied, yet trade-offs can also involve behavioural or cognitive traits. READ MORE

  7. 10. Trade-off analysis of forest ecosystem services – A modelling approach

    Author : Xi Pang; Ulla Mörtberg; Berit Balfors; Brian Fath; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Forest bioenergy feedstock; Landscape simulation; Forest simulation; Ecosystem services modelling; Integrated sustainability assessment; Spatial optimization; Optimization heuristics; Mark- och vattenteknik; Land and Water Resources Engineering;

    Abstract : Forest is a resource that is increasingly utilized for multiple purposes. The balance between energy demands and the long-term capacity of ecosystems to support biodiversity and other ecosystem services is crucial. READ MORE
