个人简介
The research interests of Osvaldo Sala include several topics, from the functioning of arid ecosystems to ecosystem services and biodiversity, and encompass several scales from local to global. Climate change will affect arid ecosystems primarily through changes in water availability. Therefore, Osvaldo has focused a large part of his research effort on understanding the effects of precipitation patterns in space and time on primary production. His research has contributed to elucidating biogeochemical and structural mechanisms explaining ecosystem lags to changes in water availability. Osvaldo Sala also explored the consequences of changes in biodiversity on the functioning of ecosystems. At the global scale, he has developed scenarios of biodiversity change for the next 50 to 100 years. He is particularly interested in working with scenarios as a way of simplifying, understanding, and communicating the complex relationships that emerge from the study of social-ecological systems.
He employs a wide variety of tools; especially manipulative field experiments, data synthesis and simulation modeling. He has worked in the Patagonian steppe, annual grasslands of California, steppes of Colorado and deserts of Southern Africa and currently he has experiments in the Chihuahuan Desert in New Mexico.
