Elements move through Earth's critical zone along interconnected pathways that are strongly influenced by fluctuations in water and energy. The biogeochemical cycling of elements is inextricably linked to changes in climate and ecological disturbances, both natural and man-made.
Biogeochemical Cycles: Ecological Drivers and Environmental Impact examines the influences and effects of biogeochemical elemental cycles in different ecosystems in the critical zone.
Volume highlights include:
- Impact of global change on the biogeochemical functioning of diverse ecosystems
- Biological drivers of soil, rock, and mineral weathering
- Natural elemental sources for improving sustainability of ecosystems
- Links between natural ecosystems and managed agricultural systems
- Non-carbon elemental cycles affected by climate change
- Subsystems particularly vulnerable to global change
The American Geophysical Union promotes discovery in Earth and space science for the benefit of humanity. Its publications disseminate scientific knowledge and provide resources for researchers, students, and professionals.
