Bark Beetle-Induced Tree Mortality Alters Stand Energy Budgets Due To Water Budget Changes
Reed, D. E., Ewers, B. E., Pendall, E., Frank, J., Kelly, R.

Insect outbreaks are major disturbances that affect a land area similar to that of forest fires across North America. The recent mountain pine bark beetle (D endroctonus ponderosae) outbreak and its associated blue stain fungi (Grosmannia clavigera) are impacting water partitioning processes of forests in the Rocky Mountain region …

Biophysical Factors And Canopy Coupling Control Ecosystem Water And Carbon Fluxes Of Semiarid Sagebrush Ecosystems
Reed, D. E., Ewers, B. E., Pendall, E., Naithani, K. J., Kwon, H., Kelly, R. D.

The sagebrush-steppe ecosystem covers much of western North America, and its productivity is sensitive to warming and increasingly variable precipitation. Interannual variation in precipitation has been shown to be the most significant factor controlling biogeochemical cycling while both soil and atmospheric drought are dominant …

The Influence Of Hydrological Variability On Inherent Water Use Efficiency In Forests Of Contrasting Composition, Age, And Precipitation Regimes In The Pacific Northwest
Kwon, H., Law, B. E., Thomas, C. K., Johnson, B. G.

The Pacific Northwest (PNW) region of the United States has some of the most productive forests in the world. As precipitation regimes may shift with changing climate in this area, droughts are predicted to increase in both frequency and degree of severity, which will have a significant impact on already drought-prone ecosystems. …

Variations In Bacterial And Archaeal Communities Along Depth Profiles Of Alaskan Soil Cores
Tripathi, B. M., Kim, M., Kim, Y., Byun, E., Yang, J., Ahn, J., Lee, Y. K.

Understating the microbial communities and ecological processes that influence their structure in permafrost soils is crucial for predicting the consequences of climate change. In this study we investigated the bacterial and archaeal communities along depth profiles of four soil cores collected across Alaska. The bacterial and archaeal …

Orchidee-Peat (Revision 4596), A Model For Northern Peatland Co≪Sub≫2≪/Sub≫, Water, And Energy Fluxes On Daily To Annual Scales
Qiu, C., Zhu, D., Ciais, P., Guenet, B., Krinner, G., Peng, S., Aurela, M., Bernhofer, C., Brümmer, C., Bret-Harte, S., Chu, H., Chen, J., Desai, A. R., Dušek, J., Euskirchen, E.

P., Sottocornola, M., Steinbrecher, R., Sachs, T., Urbaniak, M., Zona, D., Ziemblinska, K.

Peatlands store substantial amounts of carbon and are vulnerable to climate change. We present a modified version of the Organising Carbon and Hydrology In Dynamic Ecosystems (ORCHIDEE) land surface model for simulating the hydrology, surface energy, and CO2 fluxes of peatlands on daily to annual timescales. The model includes a …

A Unique Combination Of Aerodynamic And Surface Properties Contribute To Surface Cooling In Restored Wetlands Of The Sacramento-San Joaquin Delta, California
Hemes, K. S., Eichelmann, E., Chamberlain, S., Knox, S. H., Oikawa, P. Y., Sturtevant, C., Verfaillie, J., Szutu, D., Baldocchi, D. D.

Land use change and management affect climate by altering both the biogeochemical and biophysical interactions between the land and atmosphere. Whereas climate policy often emphasizes the biogeochemical impact of land use change, biophysical impacts, including changes in reflectance, energy partitioning among sensible and latent …

A Biogeochemical Compromise: The High Methane Cost Of Sequestering Carbon In Restored Wetlands
Hemes, K. S., Chamberlain, S. D., Eichelmann, E., Knox, S. H., Baldocchi, D. D.

Peatland drainage is an important driver of global soil carbon loss and carbon dioxide (CO2) emissions. Restoration of peatlands by re‐flooding reverses CO2 losses at the cost of increased methane (CH4) emissions, presenting a biogeochemical compromise. While restoring peatlands is a potentially effective method for sequestering …

Assessing The Interplay Between Canopy Energy Balance And Photosynthesis With Cellulose δ18o: Large-Scale Patterns And Independent Ground-Truthing
Helliker, B. R., Song, X., Goulden, M. L., Clark, K., Bolstad, P., Munger, J. W., Chen, J., Noormets, A., Hollinger, D., Wofsy, S., Martin, T., Baldocchi, D., Euskirchenn, E., Desai, A., Burns, S. P.

There are few whole-canopy or ecosystem scale assessments of the interplay between canopy temperature and photosynthesis across both spatial and temporal scales. The stable oxygen isotope ratio (δ18O) of plant cellulose can be used to resolve a photosynthesis-weighted estimate of canopy temperature, but the method requires independent …

Changes In Photosynthesis And Soil Moisture Drive The Seasonal Soil Respiration-Temperature Hysteresis Relationship
Zhang, Q., Phillips, R. P., Manzoni, S., Scott, R. L., Oishi, A. C., Finzi, A., Daly, E., Vargas, R., Novick, K. A.

In nearly all large-scale terrestrial ecosystem models, soil respiration is represented as a function of soil temperature. However, the relationship between soil respiration and soil temperature is highly variable across sites and there is often a pronounced hysteresis in the soil respiration-temperature relationship over the course …
