Sarah E Hobbie

Sarah E Hobbie is a Regents Professor in the Department of Ecology, Evolution and Behavior at the University of Minnesota, actively contributing to ecological research with a focus on biogeochemical cycles and ecosystem dynamics. Her work spans terrestrial ecosystems including grasslands, forests, and urban environments.

Her research interests center on grassland ecology, soil organic matter dynamics, and biodiversity-stability relationships. Key themes include carbon sequestration mechanisms, nutrient cycling under global change, plant-soil-microbe interactions, and urban ecosystem functioning. Her fingerprint analysis reveals strong expertise in Grassland Ecology (100%), Soil Carbon (43%), Biodiversity (43%), and Litter Decomposition (41%).

Current research examines nutrient co-limitation effects on grassland productivity (2025), chronic nitrogen addition impacts on soil biogeochemistry (2025), and urban forest diversity determinants using remote sensing (2025). Her publication record shows consistent output with 273 research items including 242 articles, with significant activity in 2024-2025.

Hobbie leads and collaborates on major NSF-funded projects including:

• LTER: The Changing Nature of Cities (2021-2027)
• BII-Implementation: Plant Biodiversity Across Scales (2020-2026)
• Collaborative Research: BoCP-Implementation on Biodiversity Stability (2023-2027)

These projects investigate urban ecosystem dynamics, biodiversity responses to environmental change, and plant trait interactions across spatial scales.

Her datasets include remotely sensed prairie function data, street sweepings nutrient analysis, and century-scale wood nitrogen trajectories, supporting open science in ecosystem research.
