  2. 21. Plant Inducible Responses to Damage: Evolution and Ecological Implications

    Author : Johannes Järemo; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; herbivory; inducible defences; compensation; Ecology; Ekologi;

    Abstract : Abstract Inducible plant responses to damage, i.e. inducible defence responses and compensatory growth responses, are theoretically examined in an evolutionary and ecological context. Inducible defences are generally considered to be beneficial under conditions of low risk of herbivory and when initial damage is moderate. READ MORE

  4. 22. The biological cost of resistance to antibiotics

    Author : Johanna Björkman; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cell and molecular biology; Cell- och molekylärbiologi; Cell and molecular biology; Cell- och molekylärbiologi; mikrobiologi; Microbiology;

    Abstract : The rate of development and stability of antibiotic resistance are determined by several factors including (i) the mutation rate, (ii) the fitness costs of resistance, and (iii) the ability of bacteria to genetically compensate for such costs.. This study has focused on the experimental measurement of these parameters in antibiotic-resistant S. READ MORE

  5. 23. Environmental compensation is not for the birds : assessing social welfare impacts of resource-based environmental compensation

    Author : Scott Cole; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Abstract : The European Union (EU) recently implemented the Environmental Liability Directive (ELD), requiring that environmental damage be restored so that the affected environment returns to (or toward) its baseline condition and the public is compensated for the initial damage and the losses during the time it takes for the environment to recover (interim losses). Equivalency Analysis (EA) represents a method for scaling environmental compensation to offset interim losses. READ MORE

  6. 24. Functional neurobiology in normal aging, mild cognitive impairment and Alzheimer's disease : focus on on visuospatial processing using functional magnetic resonance imaging

    Author : Patrizia Vannini; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Alzheimer s disease; brain function; functional magnetic resonance imaging; mild cognitive impairment; normal aging; task demand; visuospatial processing;

    Abstract : With the proportional increase of the aging population in the coming decades as well as a continuously augmenting life expectancy, the effects of neurodegeneration on brain function are a topic of increasing importance. Of special interest are tools that probe the functional consequences of neurodegenerative processes and possible compensatory mechanisms that might emerge. READ MORE

  7. 25. Migration and quality of landlocked Atlantic salmon smolt : Implications for conservation and management

    Author : Johnny R Norrgård; Eva Bergman; Larry A Greenberg; Monika Schmitz; Martyn Lucas; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; acoustic telemetry; hatchery; life history; migration mortality; regulated rivers; Salmo salar; salmon; smolt; trout; Biology; Biologi;

    Abstract : Atlantic salmon Salmo salar has a complex life cycle, including long migrations and habitat shifts for both juveniles and adults. As such, salmon populations are vulnerable to habitat degradation and fragmentation along their migratory routes. READ MORE
