Comparison of phenotypic plasticity in Bistorta vivipara in topographically rough and flat landscapes
Gardiner, Emmanuel (Master thesis, 2013)Range shift in alpine plants:the study was intended to investigate if topographic effects on environmental conditions (soil moisture) will enhance plasticity in plants (alpine species). Thus, if topography will serve as a ... -
Evolvability and trait function predict phenotypic divergence of plant populations
Opedal, Øystein Hjorthol; Armbruster, Scott; Hansen, Thomas Fredrik; Holstad, Agnes; Pelabon, Christophe; Andersson, Stefan; Campbell, Diane R.; Caruso, Christina M.; Delph, Lynda F.; Eckert, Christopher G.; Lankinen, Åsa; Walter, Greg M.; Ågren, Jon; Bolstad, Geir Hysing (Peer reviewed; Journal article, 2023)Understanding the causes and limits of population divergence in phenotypic traits is a fundamental aim of evolutionary biology, with the potential to yield predictions of adaptation to environmental change. Reciprocal ... -
Fitness costs of delayed pollination in a mixed-mating plant
Hildesheim, Laura; Opedal, Øystein Hjorthol; Armbruster, Scott; Pelabon, Christophe (Journal article; Peer reviewed, 2019)Background and Aims To predict the evolutionary consequences of pollinator declines, we need to understand the evolution of delayed autonomous self-pollination, which is expected to evolve as a mechanism of reproductive ... -
Quantitative and qualitative consequences of reduced pollen loads in a mixed-mating plant
Hildesheim, Laura; Opedal, Øystein Hjorthol; Armbruster, Scott; Pelabon, Christophe (Journal article; Peer reviewed, 2019)Greater pollination intensity can enhance maternal plant fitness by increasing seed set and seed quality as a result of more intense pollen competition or enhanced genetic sampling. We tested experimentally these effects ... -

The Evolution of Herkogamy: Pollinator Reliability, Natural Selection, and Trait Evolvability
Opedal, Øystein Hjorthol (Doctoral theses at NTNU;2017:68, Doctoral thesis, 2017)Most flowering plants, including major crops, rely on animal pollinators for sexual reproduction. Therefore, recent declines in pollinator populations worldwide pose significant threats to food production and biodiversity. ...
