1. [Article] Long-Term Integrated Studies Show Complex and Surprising Effects of Climate Change in the Northern Hardwood Forest
Evaluations of the local effects of global change are often confounded by the interactions of natural and anthropogenic factors that overshadow the effects of climate changes on ecosystems. Long-term watershed ...Citation -
2. [Article] Climate Change Decreases Nitrogen Pools and Mineralization Rates in Northern Hardwood Forests
Nitrogen (N) supply often limits the productivity of temperate forests and is regulated by a complex mix of biological and climatic drivers. In excess, N is linked to a variety of soil, water, and air ...Citation -
Understanding and predicting the extent, location, and function of biogeochemical hot spots at the watershed scale is a frontier in environmental science. We applied a hydropedologic approach to identify ...

4. [Article] Winter Climate Change Affects Growing-Season Soil Microbial Biomass and Activity in Northern Hardwood Forests
Understanding the responses of terrestrial ecosystems to global change remains a major challenge of ecological research. We exploited a natural elevation gradient in a northern hardwood forest to determine ...Citation -
5. [Article] Reduced Snow Cover Alters Root-microbe Interactions and Decreases Nitrification Rates in a Northern Hardwood Forest
Snow cover is projected to decline during the next century in many ecosystems that currently experience a seasonal snowpack. Because snow insulates soils from frigid winter air temperatures, soils are ...Citation -
6. [Article] Ecosystem Services in Managing Residential Landscapes: Priorities, Value Dimensions, and Cross-Regional Patterns
Although ecosystem services have been intensively examined in certain domains (e.g., forests and wetlands), little research has assessed ecosystem services for the most dominant landscape type in urban ...Citation -
7. [Article] Convergence of Microclimate in Residential Landscapes Across Diverse Cities in the United States
Context The urban heat island (UHI) is a welldocumented pattern of warming in cities relative to rural areas. Most UHI research utilizes remote sensing methods at large scales, or climate sensors in single ...Citation
