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...

Calculating CO2 and H2O eddy covariance fluxes from an enclosed gas analyzer using an instantaneous mixing ratio

Creator:: Burba, George, Schmidt, Andres, Scott, Russell L., Nakai, Taro, Kathilankal, James, Fratini, Gerardo, Hanson, Chad, Law, Beverly, McDermitt, Dayle K., Eckles, Robert, Furtaw, Michael, and Velgersdyk, Michael
Abstract:: Eddy covariance flux research has relied on open- or closed-path gas analyzers for producing estimates of net ecosystem exchange of carbon dioxide (CO₂) and water vapor (H₂O). The two instruments have had different challenges that have led to development of an enclosed design that is intended to maximize strengths and...

Impacts of disturbance on the terrestrial carbon budget of North America

Creator:: Kasischke, Eric S., Amiro, Brian D., Barger, Nichole N., French, Nancy H. F., Goetz, Scott J., Grosse, Guido, Harmon, Mark E., Hicke, Jeffrey A., Liu, Shuguang, and Masek, Jeffrey G.
Abstract:: Because it is an important regulator of terrestrial carbon cycling in North America, extensive research on natural and human disturbances has been carried out as part of the North American Carbon Program and the CarboNA project. A synthesis of various components of this research was carried out, and the results...

Forecasting functional implications of global changes in riparian plant communities

Creator:: Kominoski, John S., Follstad Shah, Jennifer J., Canhoto, Cristina, Fischer, Dylan G., Giling, Darren P., Gonzalez, Eduardo, Griffiths, Natalie A., Larranaga, Aitor, LeRoy, Carri J., Mineau, Madeleine M., McElarney, Yvonne R., Shirley, Susan M., Swan, Christopher M., and Tiegs, Scott D.
Abstract:: Riparian ecosystems support mosaics of terrestrial and aquatic plant species that enhance regional biodiversity and provide important ecosystem services to humans. Species composition and the distribution of functional traits - traits that define species in terms of their ecological roles - within riparian plant communities are rapidly changing in response...

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...

Riparian litter inputs to streams in the central Oregon Coast Range

Creator:: Hart, Stephanie K., Hibbs, David E., and Perakis, Steven S.
Abstract:: Riparian-zone vegetation can influence terrestrial and aquatic food webs through variation in the amount, timing, and nutritional content of leaf and other litter inputs. We investigated how riparianforest community composition, understory density, and lateral slope shaped vertical and lateral litter inputs to 16 streams in the Oregon Coast Range. Riparian...

On the temporal upscaling of evapotranspiration from instantaneous remote sensing measurements to 8-day mean daily-sums

Creator:: Ryu, Youngryel, Baldocchi, Dennis D., Black, T.

Abstract:: The regular monitoring of evapotranspiration from satellites has been limited because of discontinuous temporal coverage, resulting in snapshots at a particular point in space and time. We developed a temporal upscaling scheme using satellite-derived instantaneous estimates of evapotranspiration to produce a daily-sum evapotranspiration averaged over an 8-day interval. We tested...

Sex-biased dispersal in a rare butterfly and the implications for its conservation

Creator:: Bennett, Victoria J., Pack, Shalynn M., Smith, Winston P., and Betts, Matthew G.
Abstract:: The survival of many species may be dependent on their ability to exist in human-altered landscapes within metapopulations; in turn, metapopulation persistence is dictated by the ability of individuals to move effectively among patches to promote recolonization. The Taylor’s checkerspot butterfly (Euphydryas editha taylori) is a species that does not...

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...
