Brian J. Enquist; Macroecology Lab

We develop predictive biodiversity science by linking plant functional biology, macroecology, and ecological theory to large-scale data, field research, and open infrastructure.

Brian J. Enquist is a Professor at the University of Arizona and an External Professor at the Santa Fe Institute. The Enquist Macroecology Lab studies how biodiversity is organized across scales, how plant form and function shape ecological systems, and how global change alters species distributions, ecosystems, and conservation risk.

Research Areas

Plant form, function, and scaling

The lab uses metabolic scaling theory, allometry, and plant functional traits to explain why organisms vary in size, architecture, physiology, and performance across the tree of life.

Allometry · Metabolic scaling · Trait-based ecology · Ecophysiology

Biodiversity patterns and prediction

Research combines biodiversity databases, statistical models, and mechanistic ideas to map where species occur, identify why biodiversity is distributed unevenly, and forecast changes through time.

Macroecology · Biodiversity informatics · Species distributions · Global change

Conservation and open ecological infrastructure

The group builds data resources, analytical tools, and scenario-based assessments that support biodiversity monitoring, extinction-risk analysis, and conservation planning.

BIEN · Open data · Conservation forecasting · Decision support

What the Lab Does

The Enquist Macroecology Lab integrates theory, field ecology, biodiversity data, and computational workflows. In practice, that means the lab:

  • develops ecological theory that connects organismal traits to ecosystem and biogeographic pattern;
  • measures plant form and function across forests, mountains, and long-term field experiments;
  • curates and uses large biodiversity resources such as BIEN and related plant-trait and occurrence databases;
  • builds models to estimate species distributions, functional diversity, extinction risk, and ecological response to climate change; and
  • creates open tools, data products, and training resources for biodiversity science.

Field Systems

Fieldwork at Rocky Mountain Biological Laboratory alpine systems
Rocky Mountain Biological Laboratory and other elevational systems support long-term climate, traits, and ecosystem research.
Tropical forest canopy research site used for biodiversity and ecosystem studies
Tropical forest plots and canopy studies connect demography, traits, carbon dynamics, and biodiversity change.

Field research informs theory rather than decorating it. The lab works across long-term ecological sites in the Rocky Mountains, tropical forest networks, and plant functional trait courses and transects in the Andes and other biodiversity-rich regions. These study systems provide the measurements needed to test ecological scaling, understand biodiversity assembly, and improve predictive models.
