The role of secondary pollinators in the evolution of complex colour signals in a bimodal pollination system

Katharine L. Khoury, Jon Ågren, Craig I. Peter, Nina Sletvold, Ethan Newman

This study examines how bird and bee pollinators influence selection on flower color in Cyrtanthus obliquus, showing that secondary pollinators contribute to shaping complex color signals.

Local adaptation of Gladiolus carneus to soil nutrient extremes in the Cape Floristic Region

Katharine L. Khoury, Ethan Newman

This study shows that Gladiolus carneus ecotypes are locally adapted to soil nutrient extremes in the Cape Floristic Region through reciprocal translocations and common garden experiments.

Ecological niche differentiation mediates near complete premating reproductive isolation within the Gladiolus carneus (Iridaceae) species complex.

Katharine L. Khoury, Shelley Edwards, Ethan Newman

The paper tests if ecological niche differentiation leads to premating reproductive isolation in Gladiolus carneus varieties, finding strong ecogeographic and phenological isolation contributes to near complete reproductive isolation.
