NSF enabled the assembly of an international, interdisciplinary team that was the first to quantitatively document body size patterns over the past 100 million years
Researchers have demonstrated that the extinction of dinosaurs some 65 million years ago paved the way for mammals to get bigger, about a thousand times larger than they had been when dinosaurs roamed the earth. The study, released today in the journal Science, is the first to quantitatively document the patterns of body size of mammals after the existence of dinosaurs.
The research, funded by a National Science Foundation (NSF) Research Coordination Network (RCN) grant, led by Principal Investigator Felisa Smith of the
, brought together an international team of paleontologists, evolutionary biologists and macroecologists from universities throughout the University of New Mexico and around the world. United States
RCN grants began in NSF's Directorate for Biological Sciences to encourage and foster communications and collaborations among scientists with common goals and interests. Groups of investigators are supported to communicate and coordinate their research efforts across disciplinary, organizational, institutional and geographical boundaries. The proposed networking activities each focus on a theme: a broad research question, a specific group of organisms, or particular technologies or approaches. Innovative ideas for implementing novel networking strategies to promote research coordination and collaboration that enable new research directions or advancement of a field are especially encouraged. What results are diverse, multi-disciplinary research teams that harness and synthesize different insights and data to achieve new, exciting discoveries.
"The findings on mammal size detailed in Science are evidence of the value of coordination networks, and of their success in bringing together scientists who have not worked together in the past," said NSF Program Manager Saran Twombly. "Smith's group had combined data in a new synthesis to advance our understanding of the evolution of body size."
Based on the success of research funded by RCN grants in NSF's Directorate for Biological Sciences, the program has been replicated in other directorates and offices throughout the foundation, including the directorates for Mathematical & Physical Sciences; Geosciences; Education & Human Resources and Social, Behavioral and Economic Sciences; as well as the offices of Polar Programs, International Science and Engineering, and Cyberinfrastructure.
