Tsunami simulations of the 1867 Virgin Island earthquake: Constraints on epicenter location and fault parameters
Roy Barkan, Uri S. ten Brink
2010, Bulletin of the Seismological Society of America (100) 995-1009
The 18 November 1867 Virgin Island earthquake and the tsunami that closely followed caused considerable loss of life and damage in several places in the northeast Caribbean region. The earthquake was likely a manifestation of the complex tectonic deformation of the Anegada Passage, which cuts across the Antilles island arc...
Characterizing wet slab and glide slab avalanche occurrence along the Going-to-the-Sun Road, Glacier National Park, Montana, USA
Erich H. Peitzsch, Jordy Hendrikx, Daniel B. Fagre, Blase Reardon
2010, Conference Paper, Proceedings: 2010 international snow science workshop
Wet slab and glide slab snow avalanches are dangerous and yet can be particularly difficult to predict. Both wet slab and glide slab avalanches are thought to depend upon free water moving through the snowpack but are driven by different processes. In Glacier National Park, Montana, both types of avalanches...

Cyanobacterial blooms were sampled in twenty-three Midwestern United States lakes and analyzed for community composition, thirteen cyanotoxins by liquid chromatography/mass spectrometry and immunoassay, and two...
Can selection on nest size from nest predation explain the latitudinal gradient in clutch size?
L. Biancucci, T. E. Martin
2010, Journal of Animal Ecology (79) 1086-1092
1. Latitudinal variation in clutch sizes of birds is a well described, but poorly understood pattern. Many hypotheses have been proposed, but few have been experimentally tested, and none have been universally accepted by researchers. 2. The nest size hypothesis posits that higher nest predation in the tropics favours selection...

This study evaluated NO3-N and phosphorus in subsurface waters during prairie establishment following decades of row-crop agriculture. A prairie seeding in late 2003 became established in 2006. Wells and suction cup samplers were monitored for NO3-N and phosphorus. Nitrate-N varied...
Recruitment of burbot (Lota lota L.) in Lake Erie: An empirical modelling approach
M.A. Stapanian, L.D. Witzel, A. Cook
2010, Ecology of Freshwater Fish (19) 326-337
World-wide, many burbot Lota lota (L.) populations have been extirpated or are otherwise in need of conservation measures. By contrast, burbot made a dramatic recovery in Lake Erie during 1993-2001 but declined during 2002-2007, due in part to a sharp decrease in recruitment. We used Akaike's Information Criterion to evaluate...
