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...

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...

Key areas for conserving United States’ biodiversity likely threatened by future land use change

Creator:: Martinuzzi, S., Radeloff, V. C., Higgins, J. V., Helmers, D. P., Plantinga, A. J., and Lewis, D. J.
Abstract:: A major challenge for biodiversity conservation is to mitigate the effects of future environmental change, such as land use, in important areas for biodiversity conservation. In the United States, recent conservation efforts by The Nature Conservancy and partners have identified and mapped the nation's Areas of Biodiversity Significance (ABS), representing...

Lymphocytic Choriomeningitis Virus Infection in FVB Mouse Produces Hemorrhagic Disease

Creator:: Schnell, Frederick J., Sundholm, Sarah, Crumley, Stacy, Iversen, Patrick L., and Mourich, Dan V.
Abstract:: The viral family Arenaviridae includes a number of viruses that can cause hemorrhagic fever in humans. Arenavirus infection often involves multiple organs and can lead to capillary instability, impaired hemostasis, and death. Preclinical testing for development of antiviral or therapeutics is in part hampered due to a lack of an...

Thermal-plume fibre optic tracking (T-POT) test for flow velocity measurement in groundwater boreholes

Creator:: Bense, V. F, Hochreutener, R., Bour, O., Le Borgne, T., Lavenant, N., and Selker, J. S.
Abstract:: We develop an approach for measuring in-well fluid velocities using point electrical heating combined with spatially and temporally continuous temperature monitoring using distributed temperature sensing (DTS). The method uses a point heater to warm a discrete volume of water. The rate of advection of this plume, once the heating is...

Carbon budget estimation of a subarctic catchment using a dynamic ecosystem model at high spatial resolution

Creator:: Tang, J., Miller, P. A., Persson, A., Olefeldt, D., Pilesjö, P., Heliasz, M., Jackowicz-Korczynski, M., Yang, Z., Smith, B., Callaghan, T. V., and Christensen, T. R.
Abstract:: Large amount of organic carbon is stored in high latitude soils. A substantial proportion of this carbon stock is vulnerable and may decompose rapidly due to temperature increases that are already greater than the global average. It is therefore crucial to quantify and understand carbon exchange between the atmosphere and...

Short-term responses of native bees to livestock and implications for managing ecosystem services in grasslands

Creator:: Kimoto, Chiho, DeBano, Sandra J., Thorp, Robbin W., Taylor, Robert V., Schmalz, Heidi, DelCurto, Timothy, Johnson, Tracey, Kennedy, Patricia L., and Rao, Sujaya
Abstract:: Rangelands are significant providers of ecosystem services in agroecosystems world‐wide. Yet few studies have investigated how different intensities of livestock grazing impact one important provider of these ecosystem services—native bees. We conducted the first large‐scale manipulative study on the effect of a gradient of livestock grazing intensities on native bees...

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...
