Webing depression. This is due in large part to the seminal but controversial work of Lande and Schemske (1985) and Schemske and Lande ( 1985). They postulated a direct link between levels of inbreeding depression and the evolution of self-fertilization, providing a rationale for measuring levels of inbreeding depression in plants.
