2009, Applied Geochemistry (24) 1106-1112
Sedimentary basins in general, and deep saline aquifers in particular, are being investigated as possible repositories for large volumes of anthropogenic CO2 that must be sequestered to mitigate global warming and related climate changes. To investigate the potential for the long-term storage of CO2 in such aquifers, 1600 t of...
Rapid changes in small fish mercury concentrations in estuarine wetlands: Implications for wildlife risk and monitoring programs
Collin A. Eagles-Smith, Joshua T. Ackerman
2009, Environmental Science & Technology (43) 8658-8664
Small fish are commonly used to assess mercury (Hg) risk to wildlife and monitor Hg in wetlands. However, limited research has evaluated short-term Hg variability in small fish, which can have important implications for monitoring programs and risk assessment. We conducted a time-series study of Hg concentrations in two small...

E.M. Thompson, L.G. Baise, R. E. Kayen, B.B. Guzina
2009, Bulletin of the Seismological Society of America (99) 2927-2949
We compare estimates of the empirical transfer function (ETF) to the plane SH-wave theoretical transfer function (TTF) within a laterally constant medium for invasive and noninvasive estimates of the seismic shear-wave slownesses at 13 Kiban-Kyoshin network stations throughout Japan. The difference between the ETF and either of the TTFs is...
Influence of trees in the landscape on parasitism rates of grassland passerine nests in Southeastern North Dakota
Pamela J. Pietz, Deborah A. Buhl, Jill A. Shaffer, Maiken Winter, Douglas H. Johnson
2009, Condor (111) 36-42
Woody vegetation has been linked to increased rates of Brown-headed Cowbird (Molothrus ater) parasitism for some grassland hosts. In northern North Dakota, however, studies reported that parasitism of grassland passerine nests was lower in landscapes with trees than in those without trees. We looked for evidence of this pattern elsewhere,...

V.V. Akinin, E. L. Miller, J. L. Wooden
2009, Special Paper of the Geological Society of America 39-68
Petrologic, geochemical, and metamorphic data on gneissic xenoliths derived from the middle and lower crust in the Neogene Bering Sea basalt province, coupled with U-Pb geochronology of their zircons using sensitive high-resolution ion microprobe-reverse geometry (SHRIMP-RG), yield a detailed comparison between the P-T-t and magmatic history of the lower crust...
Is there evidence of adaptation to tidal flooding in saplings of baldcypress subjected to different salinity regimes?
K. W. Krauss, T.W. Doyle, R.J. Howard
2009, Environmental and Experimental Botany (67) 118-126
Plant populations may adapt to environmental conditions over time by developing genetically based morphological or physiological characteristics. For tidal freshwater forested wetlands, we hypothesized that the conditions under which trees developed led to ecotypic difference in response of progeny to hydroperiod. Specifically, we looked for evidence of ecotypic adaptation for...
Learning to be different: Acquired skills, social learning, frequency dependence, and environmental variation can cause behaviourally mediated foraging specializations
M. T. Tinker, M. Mangel, J. A. Estes
2009, Evolutionary Ecology Research (11) 841-869
Question: How does the ability to improve foraging skills by learning, and to transfer that learned knowledge, affect the development of intra-population foraging specializations? Features of the model: We use both a state-dependent life-history model implemented by stochastic dynamic programming (SDPM) and an individual-based model (IBM) to capture the dynamic...

2009, Emerging Infectious Diseases (15) 2021-2024
Plague seroprevalence was estimated in populations pumas and bobcats in the western United States. High levels of exposure in plague-endemic regions indicate the need to consider the ecology and pathobiology of plague nondomestic felid hosts to better understand the role of these species in disease persistence and transmission....
A new numerical method for calculating extrema of received power for polarimetric SAR
Y. Zhang, Jiahua Zhang, Z. Lu, W. Gong
2009, IEEE Geoscience and Remote Sensing Letters (6) 666-670
A numerical method called cross-step iteration is proposed to calculate the maximal/minimal received power for polarized imagery based on a target's Kennaugh matrix. This method is much more efficient than the systematic method, which searches for the extrema of received power by varying the polarization ellipse angles of receiving and...
