T. J. Horner, M. Schonbachler, M. Rehkämper, S.G. Nielsen, H. Williams, A. N. Halliday, Z. George Xue, James R. Hein
2010, Geochemistry, Geophysics, Geosystems (11)
The geochemistry of Cd in seawater has attracted significant attention owing to the nutrient-like properties of this element. Recent culturing studies have demonstrated that Cd is a biologically important trace metal that plays a role in the sequestration of inorganic carbon. This conclusion is supported by recent isotope data for...
Reply to “Comment on ‘Is There a Basis for Preferring Characteristic Earthquakes over a Gutenberg–Richter Distribution in Probabilistic Earthquake Forecasting?’ by Tom Parsons and Eric L. Geist” by Jens-Uwe Klügel
Thomas E. Parsons, Eric L. Geist
2010, Bulletin of the Seismological Society of America (100) 898-899
The focus of Parsons and Geist (2009) was to test whether the key observational data used in earthquake forecasting necessitate a characteristic earthquake rupture model. The point of our article was not to suggest that a specific form of the Gutenberg–Richter earthquake distribution is a perfect representation of reality. The...

Peter James Brown, Michael A. Bozek
2010, Transactions of the American Fisheries Society (139) 1247-1260
Habitat use during early life history plays an important role in the ecology of smallmouth bass Micropterus dolomieu in north temperate lakes. The highest levels of mortality occur during the first year of life, and the habitat selected probably affects mortality. We used resource selection functions and abundance data from two...
