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 …

Decadal-Scale Reduction In Forest Net Ecosystem Production Following Insect Defoliation Contrasts With Short-Term Impacts Of Prescribed Fires
Clark, K., Renninger, H., Skowronski, N., Gallagher, M., Schäfer, K.

Understanding processes underlying forest carbon dynamics is essential for accurately predicting the outcomes of non-stand-replacing disturbance in intermediate-age forests. We quantified net ecosystem production (NEP), aboveground net primary production (ANPP), and the dynamics of major carbon (C) pools before and during the decade …

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 …

Merging a mechanistic enzymatic model of soil heterotrophic respiration into an ecosystem model in two AmeriFlux sites of northeastern USA
Sihi, D, Davidson, E.A., Chen, M, Savage, K.E., Richardson, A.D., Keenan, T.F., Hollinger, D. Y.

Heterotrophic respiration (Rh), microbial processing of soil organic matter to carbon dioxide (CO2), is a major, yet highly uncertain, carbon (C) flux from terrestrial systems to the atmosphere. Temperature sensitivity of Rh is often represented with a simple Q10 function in ecosystem models and earth system models (ESMs), sometimes …

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. …

The Effect Of Land Cover Type And Structure On Evapotranspiration From Agricultural And Wetland Sites In The Sacramento–San Joaquin River Delta, California
Eichelmann, E., Hemes, K. S., Knox, S. H., Oikawa, P. Y., Chamberlain, S. D., Sturtevant, C., Verfaillie, J., Baldocchi, D. D.

Water is a limited and valuable resource in California. A large proportion of the fresh water for southern California is supplied by the Sacramento and San Joaquin rivers. With recent efforts to restore large areas of land in the Sacramento–San Joaquin Delta region from farmland to managed wetlands, it is important to investigate …

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 …

Rain-fed and irrigated cropland-atmosphere water fluxes and their implications for agricultural production in Southern Amazonia
Lathuillière, M.J., Dalmagro, H.J., Black, T.A., Arruda, P.H., Hawthorne, I., Couto, E.G., Johnson, M.S.

Cropland has increasingly occupied large areas in Southern Amazonia since the 1990s, yet few direct field-based evapotranspiration (ET) measurements are available. We used the eddy covariance method to measure ET on a farm with multiple cropping cycles per year over September 2015 through February 2017. This period covered two soybean …
