Abstract

The idea that biological diversity enhances ecological stability has inspired a huge body of scientific research, from the 1950's and before to the 2000's and beyond. It has also played an important role in environmental ethics, e.g., in Leopold's land ethic. In his view, biodiversity is essential for "a food chain aimed to harmonize the wild and the tame in the joint interest of stability, productivity, and beauty." (1949, p. 199) Then, as now, potential links between diversity and stability helped to whet the impetus for conservation.
