Do Pollinators Drive Divergence? Connecting Floral Phenotypes, Pollinators, and Gene Flow to Understand Floral Trait Divergence in Castilleja

Description:

Interactions with pollinators are thought to be a major driver of the evolution and diversification of angiosperms, yet questions remain about how pollinators mediate plant divergence at early stages and across entire species distributions. Here, I address this knowledge gap using two study groups in the recently-radiating and florally diverse...

Tradeoffs Between Reproduction and Aging in the Human Epigenome

Description:

Evolutionary theory predicts that reproduction entails energetic costs that detract from somatic maintenance, accelerating biological aging. In women, such ‘costs of reproduction’ (CoR) are thought to arise predominantly during pregnancy and lactation, while in men the physiological effects of the steroid hormone testosterone (T) are believed to be a major...
