Reconstructing the evolutionary history of herbaceous crops through trait‐based ecology

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Reconstructing the evolution of crop plants is fundamental to understanding their origins, ecological adaptations, and impacts on ecosystem processes. However, our understanding of crop evolution stems largely from archaeology and genetics, with less focus on a trait‐based ecological approach.

Causes of delayed angiosperm diversification: The photosynthetic revolution, increased opportunity costs of anti‐herbivore defenses, selection for qualitative toxins, and acceleration of plant–herbivore coevolution

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Why did it take so long for angiosperms to diversify after they arose? Here I consider the indirect but potentially crucial impact of the “photosynthetic revolution” on plant–herbivore coevolution. Increased vein density in fossil leaves implies a doubling in photosynthesis 125–100 million years ago.

Co‐flowering with congeners does not affect buzz‐pollinator specialization and pollination performance in Rhexia mariana, but does affect floral trait variance

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Pollinator‐mediated plant‐plant interactions may be negative (i.e., competition, reproductive interference) or positive (i.e., facilitation). Especially when co‐flowering with close relatives (e.g., congeners), negative interactions through reproductive interference may be strong and result in floral trait divergence and increased ...
