Management trade-off between aboveground carbon storage and understory plant species richness in temperate forests

Creator:: Burton, Julia I., Ares, Adrian, Olson, Deanna H., and Puettmann, Klaus J.
Abstract:: Because forest ecosystems have the capacity to store large quantities of carbon (C), there is interest in managing forests to mitigate elevated CO[subscript 2] concentrations and associated effects on the global climate. However, some mitigation techniques may contrast with management strategies for other goals, such as maintaining and restoring biodiversity....

Decomposition of heterogeneous organic matter and its long-term stabilization in soils

Creator:: Sierra, Carlos A., Harmon, Mark E., and Perakis, Steven S.
Abstract:: Soil organic matter is a complex mixture of material with heterogeneous biological, physical, and chemical properties. Decomposition models represent this heterogeneity either as a set of discrete pools with different residence times or as a continuum of qualities. It is unclear though, whether these two different approaches yield comparable predictions...

Empirical assessment of uncertainties of meteorological parameters and turbulent fluxes in the AmeriFlux network

Creator:: Schmidt, Andres, Hanson, Chad, Chan, W. Stephen, and Law, Beverly E.
Abstract:: Terrestrial ecosystem-atmosphere exchange of carbon, water vapor, and energy has been measured for over a decade at many sites globally. To minimize measurement and analysis errors, quality assurance data have been collected over short periods along-side tower instruments at AmeriFlux research sites. Theoretical and empirical error and uncertainty values have...

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...

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...

Range Contractions of North American Carnivores and Ungulates

Creator:: Laliberte, Andrea S. and Ripple, William J.
Abstract:: We compared the historic and current geographical ranges of 43 North American carnivores and ungulates to identify large-scale patterns in range contractions and expansions. Seventeen of the species had experienced range contractions over more than 20% of their historic range. In areas of higher human influence, species were more likely...

Habitat selection by juvenile Swainson’s thrushes (Catharus ustulatus) in headwater riparian areas, Northwestern Oregon, USA

Creator:: Jenkins, Stephanie R., Betts, Matthew G., Huso, Manuela M., and Hagar, Joan C.
Abstract:: Lower order, non-fish-bearing streams, often termed ‘‘headwater streams’’, have received minimal research effort and protection priority, especially in mesic forests where distinction between riparian and upland vegetation can be subtle. Though it is generally thought that breeding bird abundance is higher in riparian zones, little is known about species distributions...

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...

Management, Morphological, and Environmental Factors Influencing Douglas-Fir Bark Furrows in the Oregon Coast Range

Creator:: Sheridan, Christopher D., Puettmann, Klaus J., Huso, Manuela M.P., Hagar, Joan C., and Falk, Kristen R.
Abstract:: Many land managers in the Pacific Northwest have the goal of increasing late-successional forest structures. Despite the documented importance of Douglas-fir tree bark structure in forested ecosystems, little is known about factors influencing bark development and how foresters can manage development. This study investigated the relative importance of tree size,...

Interactive visual analysis promotes exploration of long-term ecological data

Creator:: Pham, Tuan, Jones, Julia A., Metoyer, Ronald, Swanson, Frederick, and Pabst, Robert
Abstract:: Long-term ecological data are crucial in helping ecologists understand ecosystem function and environmental change. Nevertheless, these kinds of data sets are difficult to analyze because they are usually large, multivariate, and spatiotemporal. Although existing analysis tools such as statistical methods and spreadsheet software permit rigorous tests of pre-conceived hypotheses and...
