Sediment cores from the western Arctic Ocean obtained on the 2005 HOTRAX and some earlier expeditions have been analyzed to develop a stratigraphic correlation from the Alaskan Chukchi margin to the Northwind and Mendeleev-Alpha ridges. The correlation was primarily based on terrigenous sediment composition that is not affected by diagenetic...
Characterizing the oxygen isotopic composition of phosphate sources to aquatic ecosystems
M.B. Young, K. McLaughlin, C. Kendall, W. Stringfellow, M. Rollog, K. Elsbury, E. Donald, A. Paytan
2009, Environmental Science & Technology (43) 5190-5196
The oxygen isotopic composition of dissolved inorganic phosphate (δ18Op) in many aquatic ecosystems is not in isotopic equilibrium with ambient water and, therefore, may reflect the source δ18Op. Identification of phosphate sources to water bodies is critical for designing best management practices for phosphate load reduction to control eutrophication. In...
Wildfire risk in the wildland-urban interface: A simulation study in northwestern Wisconsin
A. Bar-Massada, V. C. Radeloff, S. I. Stewart, T. J. Hawbaker
2009, Forest Ecology and Management (258) 1990-1999
The rapid growth of housing in and near the wildland-urban interface (WUI) increases wildfire risk to lives and structures. To reduce fire risk, it is necessary to identify WUI housing areas that are more susceptible to wildfire. This is challenging, because wildfire patterns depend on fire behavior and spread, which...

Ann Harding, Alexander S. Kitaysky, Keith C. Hamer, Margaret E. Hall, Jorg Welcker, Sandra L. Talbot, Nina J. Karnovsky, Geir W. Gabrielsen, David Gremillet
2009, Animal Behaviour (78) 321-328
We examined how short-term impacts of experimentally increased foraging effort by one parent reverberate around the family in a monomorphic seabird (little auk, Alle alle), and whether these effects depend on offspring sex. In many species, more effort is required to rear sons successfully than daughters. However, undernourishment may have...
Suggested notation conventions for rotational seismology
J.R. Evans
2009, Bulletin of the Seismological Society of America (99) 1073-1075
We note substantial inconsistency among authors discussing rotational motions observed with inertial seismic sensors (and much more so in the broader topic of rotational phenomena). Working from physics and other precedents, we propose standard terminology and a preferred reference frame for inertial sensors (Fig. 1) that may be consistently used...

P.V. Sundareshwar, C.J. Richardson, R.A. Gleason, P.J. Pellechia, S. Honomichl
2009, Geophysical Research Letters (36)
Land-use change has altered the ability of wetlands to provide vital services such as nutrient retention. While compensatory practices attempt to restore degraded wetlands and their functions, it is difficult to evaluate the recovery of soil biogeochemical functions that are critical for restoration of ecosystem services. Using solution 31P Nuclear...
Expansion of Dreissena into offshore waters of Lake Michigan and potential impacts on fish populations
D.B. Bunnell, C.P. Madenjian, J.D. Holuszko, J.V. Adams, J. R. P. French III
2009, Journal of Great Lakes Research (35) 74-80
Lake Michigan was invaded by zebra mussels (Dreissena polymorpha) in the late 1980s and then followed by quagga mussels (D. bugensis) around 1997. Through 2000, both species (herein Dreissena) were largely restricted to depths less than 50??m. Herein, we provide results of an annual lake-wide bottom trawl survey in Lake...
Utilization by fishes of the Alviso Island ponds and adjacent waters in south san francisco bay following restoration to tidal influence
M. K. Saiki, F.H. Mejia
2009, California Fish and Game (95) 38-52
Earthen levees of three isolated salt ponds known locally as the Alviso Island Ponds were intentionally breached in March 2006 to allow tidal exchange of the ponds with water from Coyote Creek. The water exchange transformed the previously fishless hypersaline ponds into lower salinity habitats suitable for fish life. This...
The morphology and distribution of submerged reefs in the Maui-Nui Complex, Hawaii: New insights into their evolution since the Early Pleistocene
Iain D.E. Faichney, James M. Webster, David A. Clague, Chris Kelley, Bruce Applegate, James G. Moore
2009, Marine Geology (265) 130-145
Reef drowning and backstepping have long been recognised as reef responses to sea-level rise on subsiding margins. During the Late Pleistocene (~500–14 ka) Hawaiian reefs grew in response to rapid subsidence and 120 m 100 kyr sea-level cycles, with recent work on the submerged drowned reefs around the...

David Twichell, Elizabeth A. Pendleton, Wayne E. Baldwin, James G. Flocks
2009, Geo-Marine Letters (29) 349-358
The Chandeleur Islands lie on the eastern side of the modern Mississippi River delta plain, near the edge of the St. Bernard Delta complex. Since abandonment approximately 2,000 years b.p., this delta complex has undergone subsidence and ravinement as the shoreline has transgressed across it. High-resolution seismic-reflection, sidescan-sonar, and...
Aggressive defensive behavior by free-ranging white-tailed deer
T.W. Grovenburg, J.A. Jenks, C.N. Jacques, R. W. Klaver, C. C. Swanson
2009, Journal of Mammalogy (90) 1218-1223
Maternal investment plays a critical role in neonate survival, and adults can improve survival of offspring by defending them against predators. However, limited information exists documenting ungulate aggression toward humans in defense of neonates. During captures of neonates in spring 2007 and 2008 in north-central South Dakota, we documented 24...
