  4. 2. Ecology and evolution of tolerance in two cruciferous species

    Author : Elin Boalt; Kari Lehtilä; Johan Ehrlén; Julia Koricheva; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; herbivory; tolerance; methodology; Raphanus raphanistrum; Cardamine pratensis; folivory; apex removal; plant competition; ploidy levels; herbivore pressure; Other biology; Övrig biologi; växtekologi; Plant Ecology;

    Abstract : Tolerance to herbivory is the ability of plants to maintain fitness in spite of damage. The goal of this thesis is to investigate the genetic variation and expression of tolerance within species, determine whether and in what conditions tolerance has negative side-effects, and how tolerance is affected by different ecological factors.

  5. 3. Context dependency of plant – animal interactions

    Author : Malin A. E. König; Johan Ehrlén; Christer Wiklund; John Stinchcombe; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Anthocharis cardamines; attack intensity; Cardamine pratensis; cytotype; herbivory; larval fitness; oviposition; phenology; plant-animal interactions; plant resistance; plant tolerance; polyploidy; spatial variation; trait variation; Plant Ecology; växtekologi;

    Abstract : The strength and direction of interactions between organisms vary spatially across the landscape. Traditionally, the focus has been on how trait variation affects the interactions between species. However, differences in abiotic and biotic environmental factors may also alter the distribution, phenology and behavior of the interacting species. READ MORE

  6. 4. Plant phenology in seasonal environments

    Author : Elsa Fogelström; Johan Ehrlén; Johan P. Dahlgren; Arthur Weis; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Autumn phenology; Cardamine pratensis; evolutionary ecology; heritability; herbivore preference; fitness components; flowering time; growing season length; life-history; Lathyrus vernus; natural selection; population differentiation; phenology; spring phenology; Plant Ecology; växtekologi;

    Abstract : Phenology, or the seasonal timing life-history events such as emergence, reproduction and senescence will determine the outcome of interactions between plants and both abiotic and biotic aspects of the environment. Such timing is therefore of utmost importance for plants in seasonal environments. READ MORE

  7. 5. Plant polyploidy and interactions with insect herbivores

    Author : Leena Arvanitis; Johan Ehrlén; Christer Wiklund; John N. Thompson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; diversicifation; herbivory; host plant preference; plant galls; plant-insect interactions; plant polyploidy; selection; spatial variation; trait-fitness relationship; Terrestrial ecology; Terrestisk ekologi; Plant Ecology; växtekologi;

    Abstract : Polyploidization has been suggested to be a common mechanism for plant speciation. Polyploidy is associated with changes in plant traits and altered habitat preference. READ MORE
