Causes and implications of the correlation between forest productivity and tree mortality rates

Creator:: Stephenson, Nathan L., van Mantgem, Phillip J., Bunn, Andrew G., Bruner, Howard, Harmon, Mark E., O'Connell, Kari B., Urban, Dean L., and Franklin, Jerry F.
Abstract:: At global and regional scales, tree mortality rates are positively correlated with forest net primary productivity (NPP). Yet causes of the correlation are unknown, in spite of potentially profound implications for our understanding of environmental controls of forest structure and dynamics and, more generally, our understanding of broad-scale environmental controls...

Uncertainty analysis: an evaluation metric for synthesis science

Creator:: Harmon, Mark E., Fasth, Becky, Halpern, Charles B., and Lutz, James A.
Abstract:: The methods for conducting reductionist ecological science are well known and widely used. In contrast, those used in the synthesis of ecological science (i.e., synthesis science) are still being developed, vary widely, and often lack the rigor of reductionist approaches. This is unfortunate because the synthesis of ecological parts into...

Evaluating rural Pacific Northwest towns for wildfire evacuation vulnerability

Creator:: Dye, Alex W., Kim, John B., McEvoy, Andrew, Fang, Fang, and Riley, Karin L.
Abstract:: Wildfire is an annual threat for many rural communities in the Pacific Northwest region of the United States. In some severe events, evacuation is one potential course of action to gain safety from an advancing wildfire. Since most evacuations occur in a personal vehicle along the surrounding road network, the...

Understanding ecohydrological connectivity in savannas: a system dynamics modelling approach

Creator:: Miller, Gretchen R., Cable, Jessica M., McDonald, Alyson K., Bond, Barbara, Franz, Trenton E., Wang, Lixin, Gou, Si, Tyler, Anna P., Zou, Chris B., and Scott, Russell L.
Abstract:: Ecohydrological connectivity is a system level property that results from the linkages in the networks of water transport through ecosystems, by which feedbacks and other emergent system behaviours may be generated. We created a system dynamics model that represents primary ecohydrological networks to examine how connectivity between ecosystem components impacts...

Trends in stream nitrogen concentrations for forested reference catchments across the USA

Creator:: Argerich, A., Johnson, S. L., Sebestyen, S. D., Rhoades, C. C., Greathouse, E., Knoepp, J. D., Adams, M. B., Likens, G. E., Campbell, J. L., McDowell, W. H., Scatena, F. N., and Ice, G. G.
Abstract:: To examine whether stream nitrogen concentrations in forested reference catchments have changed over time and if patterns were consistent across the USA, we synthesized up to 44 yr of data collected from 22 catchments at seven USDA Forest Service Experimental Forests. Trends in stream nitrogen presented high spatial variability both...

Use of change-point detection for friction–velocity threshold evaluation in eddy-covariance studies

Creator:: Barr, A. G., Richardson, A. D., Hollinger, D. Y., Papale, D., Arain, M. A., Black, T. A., Bohrer, G., Dragoni, D., Fischer, M. L., Gu, L., Law, B. E., Margolis, H. A., McCaughey, J. H., Munger, J. W., Oechel, W., and Schaeffer, K.
Abstract:: The eddy-covariance method often underestimates fluxes under stable, low-wind conditions at night when turbulence is not well developed. The most common approach to resolve the problem of nighttime flux underestimation is to identify and remove the deficit periods using friction-velocity (u*) threshold filters (u*[superscript Th]). This study modifies an accepted...

Ecological effects of alternative fuel-reduction treatments: highlights of the National Fire and Fire Surrogate study (FFS)

J., Edminster, Carl B., Erickson, Karen L., Farris, Kerry L., Fettig, Christopher J., Fiedler, Carl E., Haase, Sally, Hart, Stephen C., Keeley, Jon E., Knapp, Eric E., Lehmkuhl, John F., Moghaddas, Jason J., Otrosina, William, Outcalt, Kenneth W., Schwilk, Dylan W., Skinner, Carl N., Waldrop, Thomas A., Weatherspoon, C. Phillip, Yaussy, Daniel A., Youngblood, Andrew, and Zack, Steve
Abstract:: The 12-site National Fire and Fire Surrogate study (FFS) was a multivariate experiment that evaluated ecological consequences of alternative fuel-reduction treatments in seasonally dry forests of the US. Each site was a replicated experiment with a common design that compared an un-manipulated control, prescribed fire, mechanical and mechanical + fire...

Abstract:: It is well established that individual organisms can acclimate and adapt to temperature to optimize their functioning. However, thermal optimization of ecosystems, as an assemblage of organisms, has not been examined at broad spatial and temporal scales. Here, we compiled data from 169 globally distributed sites of eddy covariance and...
