Exploring individual quality: Basal metabolic rate and reproductive performance in storm-petrels
A.L. Blackmer, R.A. Mauck, Joshua T. Ackerman, C.E. Huntington, G.A. Nevitt, J. B. Williams
2005, Behavioral Ecology (16) 906-913
Despite evidence that some individuals achieve both superior reproductive performance and high survivorship, the factors underlying variation in individual quality are not well understood. The compensation and increased-intake hypotheses predict that basal metabolic rate (BMR) influences reproductive performance; if so, variation in BMR may be related to differences in individual...

Osmium isotope stratigraphy of a marine ferromanganese crust
V. Klemm, S. Levasseur, M. Frank, J.R. Hein, A. N. Halliday
2005, Earth and Planetary Science Letters (238) 42-48
Ferromanganese crusts provide records of long term change in ocean circulation and continental weathering. However, calibrating their age prior to 10 Ma has been entirely based on empirical growth rate models using Co concentrations, which have inherently large uncertainties and fail to detect hiatuses and erosional events. We present a...
Stable isotope ratios in swale sequences of Lake Superior as indicators of climate and lake level fluctuations during the Late Holocene
Shruti Sharma, G. Mora, J.W. Johnston, T.A. Thompson
2005, Quaternary Science Reviews (24) 1941-1951
Beach ridges along the coastline of Lake Superior provide a long-term and detailed record of lake level fluctuations for the past 4000 cal BP. Although climate change has been invoked to explain these fluctuations, its role is still in debate. Here, we reconstruct water balance by employing peat samples collected...

Sites included a reference and treatment site...
Liquefaction at Oceano, California, during the 2003 San Simeon earthquake
T.L. Holzer, T.E. Noce, M.J. Bennett, J. C. Tinsley III, L.I. Rosenberg
2005, Bulletin of the Seismological Society of America (95) 2396-2411
The 2003 M 6.5 San Simeon, California, earthquake caused liquefaction-induced lateral spreading at Oceano at an unexpectedly large distance from the seismogenic rupture. We conclude that the liquefaction was caused by ground motion that was enhanced by both rupture directivity in the mainshock and local site amplification by unconsolidated fine-grained...
