| Ecosystem Services | How are environmental changes affecting critical ecosystem services - natural and cultural resources, human health, infrastructure, and climate regulation - and how are human societies responding? |
| Disturbance Regimes | What processes are contributing to changes in disturbance regimes and what are the impacts of these changes? |
| Permafrost | What processes are controlling changes in the distribution and properties of permafrost and what are the impacts of these changes? |
| Hydrologic System | What are the causes and consequences of changes in the hydrologic system, specifically the amount, temp oral distribution, and discharge of surface and subsurface water? |
| Flora and Fauna | How are flora and fauna responding to changes in biotic and abiotic conditions, and what are the impacts on ecosystem structure and function? |
| Carbon Pools | How are the magnitudes, fates, and land - atmosphere exchanges of carbon pools responding to environmental change, and what are the biogeochemical mechanisms driving these changes? |
| Permafrost Vulnerability / Resilience | Determine how interactions among vegetation, soil characteristics, hydrology, and disturbances influence surface energy exchange and mediate permafrost vulnerability and resilience to climate change. |
| Microbes, Plants, Animal Interactions | Determine how and where interactions among microbes, plants, and animals exert control over ecosystem responses to climate change and disturbances. |
| Vegetation, hydrology, disturbance interactions | Understand how vegetation attributes and hydrologic conditions interact, and respond and feedback to disturbance. |
| Snow Impacts | Quantify how changes in the spatial and temporal distribution of snow impacts ecosystem structure and function. |
| Vegetation Greening and Browning | Determine the causes of greening and browning trends and their impacts on ecosystem form and function. |
| Controls on Carbon Biogeochemistry | Elucidate how climate change and disturbances interact with above - and belowground communities and processes to alter carbon biogeochemistry, including release to surface waters and the atmosphere. |
| Changes to Fish and Wildlife Habitat | Determine how the spatial and temporal dynamics in both faunal abundance and characteristics of fish and wildlife habitat co-vary across gradients of climate and disturbance. |
| Transportation & Infrastructure | Assess how future climate warming is likely to affect infrastructure and transportation networks. |
| Human Health | Determine how changes to disturbance regimes, flora and fauna, permafrost conditions, and/or hydrology influence human health outcomes in the ABR. |
| Subsistence | Evaluate how changes to ecosystems will influence subsistence opportunities. |
| Land Management | Analyze how changes to natural and cultural resources will impact local communities as well as influence land management policies and practices. |
| Climate Regulation | Determine the sources of variations in climate feedbacks from Arctic and boreal ecosystems and assess the potential for future changes to climate regulating services at regional to global scales. |
| Ecosystem Services Interactions | Determine the degree to which changing environment and altered human activities result in synergistic or antagonistic changes in ecosystem services. |
