Evaluation and improvement of the Community Land Model (CLM4) in Oregon forests

Creator:: Hudiburg, T. W., Law, B. E., and Thornton, P. E.
Abstract:: Ecosystem process models are important tools for determining the interactive effects of global change and disturbance on forest carbon dynamics. Here we evaluated and improved terrestrial carbon cycling simulated by the Community Land Model (CLM4), the land model portion of the Community Earth System Model (CESM1.0.4). Our analysis was conducted...

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...

Amplification and dampening of soil respiration by changes in temperature variability

Creator:: Sierra, C. A., Harmon, M. E., Thomann, E., Perakis, S. S., and Loescher, H. W.
Abstract:: Accelerated release of carbon from soils is one of the most important feedbacks related to anthropogenically induced climate change. Studies addressing the mechanisms for soil carbon release through organic matter decomposition have focused on the effect of changes in the average temperature, with little attention to changes in temperature variability....

Multi-scale spatial controls of understory vegetation in Douglas-fir–western hemlock forests of western Oregon, USA

Creator:: Burton, Julia I., Ganio, Lisa M., and Puettmann, Klaus J.
Abstract:: Forest understory vegetation is influenced by broad-scale variation in climate, intermediate-scale variation in topography, disturbance and neighborhood interactions. However, little is known about how these multi-scale controls interact to influence observed spatial patterns. We examined relationships between the aggregated cover of understory plant species (%C[subscript U]) and multi-scale controls using...

The plant phenology monitoring design for The National Ecological Observatory Network

Creator:: Elmendorf, Sarah C., Jones, Katherine D., Cook, Benjamin I., Diez, Jeffrey M., Enquist, Carolyn A. F., Hufft, Rebecca A., Jones, Matthew O., Mazer, Susan J., Miller-Rushing, Abraham J., Moore, David J. P., Schwartz, Mark D., and Weltzin, Jake F.
Abstract:: Phenology is an integrative science that comprises the study of recurring biological activities or events. In an era of rapidly changing climate, the relationship between the timing of those events and environmental cues such as temperature, snowmelt, water availability, or day length are of particular interest. This article provides an...

Switching Hemispheres: A New Migration Strategy for the Disjunct Argentinean Breeding Population of Barn Swallow (Hirundo rustica)

Creator:: Garcia-Perez, Belen, Hobson, Keith A., Powell, Rebecca L., Still, Christopher J., and Huber, Gernot H.
Abstract:: Background: Barn Swallows (Hirundo rustica) breed almost exclusively in the Northern Hemisphere. However, since the early 1980's, a small disjunct breeding population has become established in eastern Argentina, presumably by birds previously derived from those breeding in North America. Currently, it is unknown where these individuals go following breeding and...

Simulated Evolution of Protein-Protein Interaction Networks with Realistic Topology

Creator:: Peterson, G. Jack, Pressé, Steve, Peterson, Kristin S., and Dill, Ken A.
Abstract:: We model the evolution of eukaryotic protein-protein interaction (PPI) networks. In our model, PPI networks evolve by two known biological mechanisms: (1) Gene duplication, which is followed by rapid diversification of duplicate interactions. (2) Neofunctionalization, in which a mutation leads to a new interaction with some other protein. Since many...

Estimating heterotrophic respiration at large scales: challenges, approaches, and next steps

Creator:: Bond-Lamberty, Ben, Epron, Daniel, Harden, Jennifer, Harmon, Mark E., Hoffman, Forrest, Kumar, Jitendra, David McGuire, Anthony, and Vargas, Rodrigo
Abstract:: Heterotrophic respiration (HR), the aerobic and anaerobic processes mineralizing organic matter, is a key carbon flux but one impossible to measure at scales significantly larger than small experimental plots. This impedes our ability to understand carbon and nutrient cycles, benchmark models, or reliably upscale point measurements. Given that a new...

Viewing forests through the lens of complex systems science

Creator:: Filotas, Elise, Parrott, Lael, Burton, Philip J., Chazdon, Robin L., Coates, K. David, Coll, Lluis, Haeussler, Sybille, Martin, Kathy, Nocentini, Susanna, Puettmann, Klaus J., Putz, Francis E., Simard, Suzanne W., and Messier, Christian
Abstract:: Complex systems science provides a transdisciplinary framework to study systems characterized by (1) heterogeneity, (2) hierarchy, (3) self‐organization, (4) openness, (5) adaptation, (6) memory, (7) non‐linearity, and (8) uncertainty. Complex systems thinking has inspired both theory and applied strategies for improving ecosystem resilience and adaptability, but applications in forest ecology...

Regional variation in stand structure and development in forests of Oregon, Washington, and inland Northern California

Creator:: Reilly, Matthew J. and Spies, Thomas A.
Abstract:: Despite its importance to biodiversity and ecosystem function, patterns and drivers of regional scale variation in forest structure and development are poorly understood. We characterize structural variation, create a hierarchical classification of forest structure, and develop an empirically based framework for conceptualizing structural development from 11,091 plots across 25 million...
