The paper examines diazotroph diversity in nodulating plants across the southeastern USA, finding host phylogeny strongly shapes symbiont composition and diversity.

The paper reassesses species limits in a syngameon of Heuchera, identifying five species and three varieties using genetic and phenotypic data.

The paper examines chloroplast capture in Heuchera hybrids, finding multiple independent events rather than a single ancestral one, and links Pleistocene climate dynamics to hybridization patterns.

The paper investigates how floral volatile organic compounds and pollinator interactions influence hybridization rates in the Heuchera genus, finding that shared attractants and pollinators correlate with higher hybridization.
