Bet hedging is not sufficient to explain germination patterns of a winter annual plant

The paper tests if bet hedging explains germination patterns in Clarkia xantiana and finds it insufficient, showing no consistent trade-off between fitness metrics.

Density dependent interactions during growth mask the effect of interactions during flowering in pollinator-sharing annual plants

The paper examines how density-dependent interactions during growth and flowering affect seed production in Clarkia plants, finding that pollinator behaviors influence flowering interactions but not total fecundity.

Selection favors adaptive plasticity in a long-term reciprocal transplant experiment

The paper tests whether phenotypic plasticity is adaptive in a plant species under source-sink dynamics, finding stabilizing selection on plasticity in specific leaf area and stomatal density.

Molecular Assays of Pollen Use Consistently Reflect Pollinator Visitation Patterns in a System of Flowering Plants

The paper compares field observations and molecular methods to assess pollen carried by bees and finds they align with pollinator visitation patterns.

Emission rates of species-specific volatiles vary across communities of Clarkia species: Evidence for character displacement in floral scent.

The paper measures volatile emission rates in Clarkia species across different community compositions, finding evidence of character displacement in floral scent.

Biotic interactions limit the geographic range of an annual plant: herbivory and phenology mediate fitness beyond a range margin

The paper investigates how herbivory and phenology affect the geographic range of Clarkia xantiana ssp. xantiana, showing herbivory reduces fitness beyond the range margin.
