High vulnerability of ecosystem function and services to diversity

The consequences of diversity loss for ecosystem functions and services are likely dependent on the shape of diversity-function or diversity-service relationships and on the range of diversity over which species are lost or added (Fig. 1). This relationship is expected to be linear with a slope of 1 ...

Restoration ecology
Restoration ecology emerged as a separate field in ecology in the 1980s. It is the scientific study supporting the practice of ecological restoration, which is the practice of renewing and restoring degraded, damaged, or destroyed ecosystems and habitats in the environment by active human intervention and action. The term ""restoration ecology"" is therefore commonly used for the academic study of the process, whereas the term ""ecological restoration"" is commonly used for the actual project or process by restoration practitioners.
