Ecosystems are critically important components of?Earth’s biological diversity and as the natural capital that sustains human life and well-being. Yet all of?the world’s ecosystems show hallmarks of human?influence, and many are under acute risks of collapse,?with consequences for habitats of species, genetic?diversity, ecosystem services, sustainable development?and human well-being. The 香港六合彩开奖结果现场直播 Global Ecosystem Typology is a hierarchical?classification system that, in its upper levels, defines ecosystems by their convergent ecological functions and, in its lower levels, distinguishes ecosystems with contrasting assemblages of species engaged in those functions.

An understanding of these traits and drivers is essential to support ecosystem management.
