Research

His lab works on developing a more integrative, quantitative, and predictive framework for biology,^[5] community ecology,^[6] and large-scale ecology.^[7] His research is notable for three areas in biology and ecology:

(1) Scaling in Biology – Enquist is notable in biology for his work with Geoffrey West and James H. Brown, in understanding the origin and diversity of organismal form, function, and diversity by developing general models for the origin of allometry and scaling laws in biology. This research,^[8] shows how general scaling laws underlie organismal form, function, and diversity and can be used to 'scale up' biological processes from genes to cells to ecosystems.^[9][10][11] This work is also the foundation for the Metabolic Theory of Ecology.

(2) Functional Plant Ecology and Trait-based biology – Enquist has worked to develop Trait Driver Theory or TDT with Van M. Savage, Jon Norberg and colleagues.^[12] TDT provides a general theory of Functional ecology in that it provides a baseline for (i) recasting the predictions of ecological theories based on species richness (see Coexistence theory) in terms of the shape of trait distributions and (ii) integrating Metabolic Scaling Theory how specific traits, including body size, and functional diversity then ‘scale up’ to influence ecosystem functioning and the dynamics of species assemblages across climate gradients. Further, TDT offers a novel framework to integrate trait, metabolic/allometric, and species-richness-based approaches and theory to better predict functional biogeography and how assemblages of species have and may respond to climate change.
