The paper investigates whether urban-rural differences in selection or pollen limitation explain a flower colour cline in Hesperis matronalis, finding no significant effects.

This study examines how mutualism affects legume niches globally, finding that mutualist species occupy broader niches than non-mutualists, with effects varying by mutualism type and latitude.

This study examines phytoplasma infection dynamics in white trillium populations, finding that low host density increases infection likelihood and that the pathogen persists across the host's range.

The paper uses herbarium specimens to show that closely related wildflower species, despite occupying diverse annual climates, track similar seasonal climate conditions through phenological shifts and spatial refugia.

The paper uses herbarium specimens to reconstruct climate conditions and assess their impact on phenology and reproduction across a plant clade, finding precipitation onset and amount best predict phenology but weakly predict reproduction.

This study finds that genetic differentiation in Clarkia pulchella is driven by geographic distance rather than climate, with distinct genetic groups at range edges and admixture in central populations.
