Seasonal carbohydrate dynamics and growth in Douglas-fir trees experiencing chronic, fungal-mediated reduction in functional leaf area

Creator:: Saffell, Brandy J., Meinzer, Frederick C., Woodruff, David R., Shaw, David C., Voelker, Steven L., Lachenbruch, Barbara, and Falk, Kristen
Abstract:: Stored non-structural carbohydrates (NSCs) could play an important role in tree survival in the face of a changing climate and associated stress-related mortality. We explored the effects of the stomata-blocking and defoliating fungal disease called Swiss needle cast on Douglas-fir carbohydrate reserves and growth to evaluate the extent to which...

Expression of functional traits during seedling establishment in two populations of Pinus ponderosa from contrasting climates

Creator:: Kerr, Kelly L., Meinzer, Frederick C., McCulloh, Katherine A., Woodruff, David R., and Marias, Danielle E.
Abstract:: First-year tree seedlings represent a particularly vulnerable life stage and successful seedling establishment is crucial for forest regeneration. We investigated the extent to which Pinus ponderosa P. & C. Lawson populations from different climate zones exhibit differential expression of functional traits that may facilitate their establishment. Seeds from two populations...

A large proportion of North American net ecosystem production is offset by emissions from harvested products, river/stream evasion, and biomass burning

Creator:: Turner, David P., Jacobson, Andrew R., Ritts, William D., Wang, Weile L., and Nemani, Ramakrishna
Abstract:: Diagnostic carbon cycle models produce estimates of net ecosystem production (NEP, the balance of net primary production and heterotrophic respiration) by integrating information from (i) satellite-based observations of land surface vegetation characteristics; (ii) distributed meteorological data; and (iii) eddy covariance flux tower observations of net ecosystem exchange (NEE) (used in...

Nitrogen limitation, ¹⁵N tracer retention, and growth response in intact and Bromus tectorum-invaded Artemisia tridentata ssp. wyomingensis communities

Creator:: Witwicki, Dana L., Doescher, Paul S., Pyke, David A., DeCrappeo, Nicole M., and Perakis, Steven S.
Abstract:: Annual grass invasion into shrub-dominated ecosystems is associated with changes in nutrient cycling that may alter nitrogen (N) limitation and retention. Carbon (C) applications that reduce plant-available N have been suggested to give native perennial vegetation a competitive advantage over exotic annual grasses, but plant community and N retention responses...

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...

Thermal optimality of net ecosystem exchange of carbon dioxide and underlying mechanisms

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...
