1. Phenotypic plasticity and local adaptation in tadpoles
Sammanfattning : Amphibian larvae are plastic in many traits. Can plasticity buffer population divergence, so that local adaptation is more common in non-plastic traits? I argue that this may be the case for adaptive plastic responses. LÄS MER
2. Phenotypic plasticity and local adaptation in island populations of Rana temporaria
Sammanfattning : Phenotypic plasticity is the ability of a genotype to express different phenotypes in different environments. Despite its common occurrence, few have investigated differences in plasticity between populations, the selection pressures responsible for it, and costs and constraints associated with it. LÄS MER
3. Intraspecific variation in Rhinanthus angustifolius. Local adaptation, phenotypic plasticity and geographical structure
Sammanfattning : Plant species often adapt to local environmental conditions, which can result in the formation of genetically and phenotypically distinct ecotypes. Ecotypes can evolve rapidly, and may be a first step in the process of ecological speciation. LÄS MER
4. Plasticity and Damage Mechanics for Modeling Concrete Failure
Sammanfattning : Concrete structures exhibit strongly non-linear and complex mechanical behavior. Hence, they are nowadays often analyzed by means of the finite element method, whereby a realistic description of the material behavior is decisive for the validity of the results. LÄS MER
5. Geographic variation in life cycles : Local adaptation and ecological genetics in a temperate butterfly
Sammanfattning : Conditions in nature change with the seasons, necessitating seasonal adaptations that synchronize the life cycles of organisms with their surroundings. Such regulatory adaptations must vary between populations to track local variation in climate and seasonality; this local adaptation is facilitated by locally specific seasonal cues, but may be hampered by gene flow and genetic history.
