Coordinating theoretical and empirical efforts to understand the linkages between organisms and environments

Abstract

Schwenk and colleagues challenged biologists to develop a deeper understanding of the linkages between organisms and environments. These linkages are captured by the concept of the niche, which has guided theoretical and empirical research in ecology for decades. Despite this research, we still cannot explain or predict much of the variation in niches over space and time. This shortcoming hinders efforts to forecast biological responses to environmental change. We believe that progress has been slowed by poor coordination between theoretical and empirical efforts to understand the evolution of niches. Therefore, progress should be sped by research programs that integrate modeling and experiments. Such research programs should focus on the structures of environmental variation, the constraints on phenotypes, and the relationships between phenotypes and fitness.
