Not just flowering time: A resurrection approach shows floral attraction traits are changing over time

The paper uses resurrection experiments to show floral traits in Ipomoea purpurea are changing over time, with increased corolla size, earlier flowering, and potential for greater floral rewards, driven by northern populations.

Females and hermaphrodites of the gynodioecious Geranium maculatum respond similarly to soil nutrient availability.

The paper compares growth and physiological responses of female and hermaphrodite Geranium maculatum plants to varying soil nutrient levels, finding similar growth responses but potential differences in chlorophyll content.

Parallel and nonparallel genomic responses contribute to herbicide resistance in Ipomoea purpurea, a common agricultural weed

This study investigates glyphosate resistance in Ipomoea purpurea, finding no changes in the target protein but identifying genomic regions under selection that show both parallel and divergent changes across resistant populations.

Environmental Influences On The Mating System Of The Common Morning Glory

The paper investigates how environmental factors influence mating system variation in the common morning glory across 22 populations.

Shifts in outcrossing rates and changes to floral traits are associated with the evolution of herbicide resistance in the common morning glory

The paper shows herbicide-resistant populations of Ipomoea purpurea self-fertilize more and have altered floral traits compared to susceptible populations.

The relative contribution of natural landscapes and human-mediated factors on the connectivity of a noxious invasive weed

This study examines how human factors and natural landscapes affect genetic connectivity in Ipomoea purpurea, finding that human population density is a key predictor of genetic differentiation.
