Amplification and dampening of soil respiration by changes in temperature variability

Creator:: Sierra, C. A., Harmon, M. E., Thomann, E., Perakis, S. S., and Loescher, H. W.
Abstract:: Accelerated release of carbon from soils is one of the most important feedbacks related to anthropogenically induced climate change. Studies addressing the mechanisms for soil carbon release through organic matter decomposition have focused on the effect of changes in the average temperature, with little attention to changes in temperature variability....

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...

Determinants of moth diversity and community in a temperate mountain landscape: vegetation, topography, and seasonality

Creator:: Highland, Steven A., Miller, Jeffrey C., and Jones, Julia A.
Abstract:: Macromoth diversity, abundance, and community structure in the topographically complex HJ Andrews Experimental Forest and LTER site was studied on the west slope of the Cascade Range, Oregon. Data on 493 macromoth species (62,221 individuals) was sampled eight times/year at 20 locations from 2004 to 2008 and examined using multivariate...

Enhancing the T-shaped learning profile when teaching hydrology using data, modeling, and visualization activities

Creator:: Sanchez, C. A., Ruddell, B. L., Schiesser, R., and Merwade, V.
Abstract:: Previous research has suggested that the use of more authentic learning activities can produce more robust and durable knowledge gains. This is consistent with calls within civil engineering education, specifically hydrology, that suggest that curricula should more often include professional perspective and data analysis skills to better develop the ‘T-shaped’...

Linked hydrologic and social systems that support resilience of traditional irrigation communities

Creator:: Fernald, A., Guldan, S., Boykin, K., Cibils, A., Gonzales, M., Hurd, B., Lopez, S., Ochoa, C., Ortiz, M., Rivera, J., Rodriguez, S., and Steele, C.
Abstract:: Southwestern US irrigated landscapes are facing upheaval due to water scarcity and land use conversion associated with climate change, population growth, and changing economics. In the traditionally irrigated valleys of northern New Mexico, these stresses, as well as instances of community longevity in the face of these stresses, are apparent....

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...

Response of the nitrogen-fixing lichen Lobaria pulmonaria to phosphorus, molybdenum, and vanadium

Creator:: Marks, Jade A., Pett-Ridge, Julie C., Perakis, Steven S., Allen, Jessica L., and McCune, Bruce
Abstract:: Nitrogen-fixing lichens (cyanolichens) are an important source of nitrogen (N) in Pacific Northwest forests, but limitation of lichen growth by elements essential for N fixation is poorly understood. To investigate how nutrient limitation may affect cyanolichen growth rates, we fertilized a tripartite cyanobacterial lichen (Lobaria pulmonaria) and a green algal...

Circumpolar Diversity and Geographic Differentiation of mtDNA in the Critically Endangered Antarctic Blue Whale (Balaenoptera musculus intermedia)

Creator:: Sremba, Angela L., Hancock-Hanser, Brittany, Branch, Trevor A., LeDuc, Rick L., and Baker, C. Scott
Abstract:: The Antarctic blue whale (Balaenoptera musculus intermedia) was hunted to near extinction between 1904 and 1972, declining from an estimated initial abundance of more than 250,000 to fewer than 400. Here, we describe mtDNA control region diversity and geographic differentiation in the surviving population of the Antarctic blue whale, using...

Factors affecting female space use in ten populations of prairie chickens

Abstract:: Conservation of wildlife depends on an understanding of the interactions between animal movements and key landscape factors. Habitat requirements of wide-ranging species often vary spatially, but quantitative assessment of variation among replicated studies at multiple sites is rare. We investigated patterns of space use for 10 populations of two closely...
