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 …

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 …

Carbon Sink And Source Dynamics Of A Eutrophic Deep Lake Using Multiple Flux Observations Over Multiple Years
David E. Reed, Hilary A. Dugan, Amelia L. Flannery, Ankur R. Desai

Recent research has shown lakes play an outsized role in carbon cycling, but long‐term continuous observations and analysis of carbon dynamics are rare, limiting our understanding of interannual variation, important timescales of variability, and drivers of efflux. Therefore, we examined lake‐atmosphere carbon fluxes with the …

Seasonal Variation Of Source Contributions To Eddy-Covariance Co 2 Measurements In A Mixed Hardwood-Conifer Forest
Kim, J., Hwang, T., Schaaf, C. L., Kljun, N., Munger, J. W.

Net ecosystem exchange (NEE) measurements using the eddy covariance technique have been widely used for calibration and evaluation of carbon flux estimates from terrestrial ecosystem models as well as for remote sensing-based estimates across various spatial and temporal scales. Therefore, it is vital to fully understand the land …

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 …

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 …
