Reproductive isolation in Drosophila involves a suite of genetic mechanisms that operate at sequential stages to prevent gene flow and facilitate speciation. Premating barriers arise through ...
A new synthesis in the Journal of Systematics and Evolution outlines how endosymbionts drive cryptic speciation in insects through ecological adaptation, horizontal gene transfer, and reproductive ...
Cospeciation is generally considered a key process driving the diversity of figs and their pollinating wasps. Ficus squamosa and Ficus heterostyla are two closely related dioecious figs. This pair ...
