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...

A bioenergetics model to evaluate demographic consequences of disturbance in marine mammals applied to gray whales

Creator:: Villegas-Amtmann, S., Schwarz, L. K., Sumich, J. L., and Costa, D. P.
Abstract:: While sophisticated tools are used to monitor behavioral changes of large marine vertebrates, determining whether these changes are meaningful for management and conservation is challenging. The Population Consequences of Disturbance model proposed a bioenergetics model to detect biologically meaningful population responses, where disturbance costs are linked to lost energy. The...

Study of Organic Semiconductors Using Time-Resolved Charge Measurements at the Microscale

Creator:: Wallace, Richard
Abstract:: Understanding charge transfer in organic semiconductors is important for developing devices like organic light emitting diodes and flexible electronics. Optical tweezers have been used in many disciplines for trapping, manipulating, and analyzing microscopic objects such as microspheres, micro-organisms, and other colloidal particles. Using optical tweezers, studies have measured the average...

Density Can Be Misleading for Low-Density Species: Benefits of Passive Acoustic Monitoring

Creator:: Rogers, Tracey L., Ciaglia, Michaela B., Klinck, Holger, and Southwell, Colin
Abstract:: Climate-induced changes may be more substantial within the marine environment, where following ecological change is logistically difficult, and typically expensive. As marine animals tend to produce stereotyped, long-range signals, they are ideal for repeatable surveying. In this study we illustrate the potential for calling rates to be used as a...

The status and challenge of global fire modelling

Creator:: Hantson, Stijn, Arneth, Almut, Harrison, Sandy P., Kelley, Douglas I., Prentice, I. Colin, Rabin, Sam S., Archibald, Sally, Mouillot, Florent, Arnold, Steve R., Artaxo, Paulo, Bachelet, Dominique, Ciais, Philippe, Forrest, Matthew, Friedlingstein, Pierre, Hickler, Thomas, Kaplan, Jed O., Kloster, Silvia, Knorr, Wolfgang, Lasslop, Gitta, Li, Fang, Mangeon, Stephane, Melton, Joe R., Meyn, Andrea, Sitch, Stephen, Spessa, Allan, van der Werf, Guido R., Voulgarakis, Apostolos, and Yue, Chao
Abstract:: Biomass burning impacts vegetation dynamics, biogeochemical cycling, atmospheric chemistry, and climate, with sometimes deleterious socio-economic impacts. Under future climate projections it is often expected that the risk of wildfires will increase. Our ability to predict the magnitude and geographic pattern of future fire impacts rests on our ability to model...

GRACE storage-streamflow hystereses reveal the dynamics of regional watersheds

Creator:: Sproles, E. A., Leibowitz, S. G., Reager, J. T., Wigington, P. J. Jr., Famiglietti, J. S., and Patil, S. D.
Abstract:: We characterize how regional watersheds function as simple, dynamic systems through a series of hysteresis loops. These loops illustrate the temporal relationship between runoff and terrestrial water storage using measurements from NASA's Gravity Recovery and Climate Experiment (GRACE) satellites in three regional-scale watersheds (>150 000 km² ) of the Columbia...

Catching the Right Wave: Evaluating Wave Energy Resources and Potential Compatibility with Existing Marine and Coastal Uses

Creator:: Kim, Choong-Ki, Toft, Jodie E., Papenfus, Michael, Verutes, Gregory, Guerry, Anne D., Ruckelshaus, Marry H., Arkema, Katie K., Guannel, Gregory, Wood, Spencer A., Bernhardt, Joanna R., Tallis, Heather, Plummer, Mark L., Halpern, Benjamin S., Pinsky, Malin L., Beck, Michael W., Chan, Francis, Chan, Kai M. A., Levin, Phil S., and Polasky, Stephen
Abstract:: Many hope that ocean waves will be a source for clean, safe, reliable and affordable energy, yet wave energy conversion facilities may affect marine ecosystems through a variety of mechanisms, including competition with other human uses. We developed a decision-support tool to assist siting wave energy facilities, which allows the...

Intra‐ and inter‐annual variation in gray whale body condition on a foraging ground

Creator:: Soledade Lemos, Leila, Burnett, Jonathan D., Chandler, Todd E., Sumich, James L., and Torres, Leigh G.
Abstract:: Baleen whales store energy gained on foraging grounds to support reproduction and other metabolic needs while fasting for long periods during migration. Whale body condition can be used to monitor foraging success, and thus better understand and anticipate individual‐ and population‐level trends in reproduction and survival. We assessed the body...
