Challenge of JaLTER: Interdisciplinary cross-site study

Forest and estuary sites are strongly over-lapped by JaLTER-site.
Mr. Sakamoto will explain details in the afternoon session.

Conclusive remark• Linkage between GEOSS and on-site
ecosystem research network with interdisciplinary approach would be quite important for ecosystem management toward the adaptation under global changes.
• Understandings of the interrelationship between carbon, water, nutrition and biodiversity in ecosystem with different environmental conditions and different spatial and temporal scale would be one of the key research themes for GEOSS-Ecosystem and Biodiversity.
