The U.S. National Science Foundation (NSF) invites submission of interdisciplinary proposals addressing grand challenges in biodiversity science within the context of unprecedented environmental change, including climate change. The program supports a comprehensive and integrative approach to understanding planetary biodiversity from a functional perspective. Research supported by this program will improve modeling and forecasting of the consequences of functional change in biodiversity. The program supports both US-only collaborative proposals and proposals with international partnerships with National Science Foundations in China, Brazil, and South Africa. Proposals may be submitted by non-profit organizations and institutions of higher education. The total anticipated funding amount is up to US$17 million. Depending on the quality of proposals, 4-6 awards are estimated to be made for design and implementation. Applications have to be submitted by 29 March 2023. Link
