Footprint of Positive Selection in Treponema pallidum subsp. pallidum Genome Sequences Suggests Adaptive Microevolution of the Syphilis Pathogen

Creator:: Giacani, Lorenzo, Chattopadhyay, Sujay, Centurion-Lara, Arturo, Jeffrey, BrendanM., Le, Hoavan T., Molini, Barbara J., Lukehart, Sheila A., Sokurenko, Evgeni V., and Rockey, Daniel D.
Abstract:: In the rabbit model of syphilis, infection phenotypes associated with the Nichols and Chicago strains of Treponema pallidum (T. pallidum), though similar, are not identical. Between these strains, significant differences are found in expression of, and antibody responses to some candidate virulence factors, suggesting the existence of functional genetic differences...

Farm Zoning and Fairness in Oregon 1964 - 2014

Creator:: Richmond, Henry R. and Houchen, Timothy G.
Abstract:: Senate Bill 100 (1973) and the Oregon Land Conservation and Development Commission’s (LCDC) goals (1975) required: - Cities to adopt urban growth boundaries (UGBs) to contain sprawl, and - Counties to use zoning to limit 15.6 million acres of farmland to farm use, and 8.0 million acres of forest land...

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...

A dual isotope approach to isolate soil carbon pools of different turnover times

Creator:: Torn, M. S., Kleber, M., Zavaleta, E. S., Zhu, B., Field, C. B., and Trumbore, S. E.
Abstract:: Soils are globally significant sources and sinks of atmospheric CO₂. Increasing the resolution of soil carbon turnover estimates is important for predicting the response of soil carbon cycling to environmental change. We show that soil carbon turnover times can be more finely resolved using a dual isotope label like the...

Long-term individual sighting history database: an effective tool to monitor satellite tag effects on cetaceans

Creator:: Gendron, D., Serrano, I. Martinez, de la Cruz, A. Ugalde, Calambokidis, J., and Mate, B.
Abstract:: During the last 3 decades, tagging technology has been used to study different aspects of cetacean ecology. Tags implanted in animal’s blubber, muscle and surrounding tissue have produced successful results, providing information on long-term movements. However, apart from the reports of ‘divots’ (depressions) and swelling at the tag sites in...

The stability and calibration of water vapor isotope ratio measurements during long-term deployments

Creator:: Bailey, A., Noone, D., Berkelhammer, M., Steen-Larsen, H. C., and Sato, P.
Abstract:: With the recent advent of commercial laser absorption spectrometers, field studies measuring stable isotope ratios of hydrogen and oxygen in water vapor have proliferated. These pioneering analyses have provided invaluable feedback about best strategies for optimizing instrumental accuracy, yet questions still remain about instrument performance and calibration approaches for multi-year...

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...

The Plant Actin Cytoskeleton Responds to Signals from Microbe-Associated Molecular Patterns

Creator:: Henty-Ridilla, Jessica L., Shimono, Masaki, Li, Jiejie, Chang, Jeff H., Day, Brad, and Staiger, Christopher J.
Abstract:: Plants are constantly exposed to a large and diverse array of microbes; however, most plants are immune to the majority of potential invaders and susceptible to only a small subset of pathogens. The cytoskeleton comprises a dynamic intracellular framework that responds rapidly to biotic stresses and supports numerous fundamental cellular...

Isotopic constraints on the pre-industrial oceanic nitrogen budget

Creator:: Somes, C. J., Oschlies, A., and Schmittner, A.
Abstract:: The size of the bioavailable (i.e., “fixed”) nitrogen inventory in the ocean influences global marine productivity and the biological carbon pump. Despite its importance, the pre-industrial rates for the major source and sink terms of the oceanic fixed nitrogen budget, N₂ fixation and denitrification, respectively, are not well known. These...
