Inference of distributional parameters from compositional samples containing nondetects
Ricardo A. Olea
2009, Conference Paper, CODAWORK’08
Low concentrations of elements in geochemical analyses have the peculiarity of being compositional data and, for a given level of significance, are likely to be beyond the capabilities of laboratories to distinguish between minute concentrations and complete absence, thus preventing laboratories from reporting extremely low concentrations of the analyte. Instead,...
Defining restoration targets for water depth and salinity in wind-dominated Spartina patens (Ait.) Muhl. coastal marshes
J.A. Nyman, Megan K. LaPeyre, Andral W. Caldwell, Sarai C. Piazza, C. Thom, C. Winslow
2009, Journal of Hydrology (376) 327-336
Coastal wetlands provide valued ecosystem functions but the sustainability of those functions often is threatened by artificial hydrologic conditions. It is widely recognized that increased flooding and salinity can stress emergent plants, but there are few measurements to guide restoration, management, and mitigation. Marsh flooding can be estimated over large...
Wildfire risk in the wildland-urban interface: A simulation study in northwestern Wisconsin
Avi Bar Massada, Volker C. Radeloff, Susan I. Stewart, Todd 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...

Multivariate Statistical Models for Predicting Sediment Yields from Southern California Watersheds
Joseph E. Gartner, Susan H. Cannon, Dennis R. Helsel, Mark Bandurraga
2009, Open-File Report 2009-1200
Debris-retention basins in Southern California are frequently used to protect communities and infrastructure from the hazards of flooding and debris flow. Empirical models that predict sediment yields are used to determine the size of the basins. Such models have been developed using analyses of records of the amount of material...

Paper birch decline in the Niobrara River Valley, Nebraska: Weather, microclimate, and birch stand conditions
Esther D. Stroh, Joel P. Miller
2009, Open-File Report 2009-1221
The Niobrara River Valley in north-central Nebraska supports scattered stands of paper birch (Betula papyrifera Marsh), a species more typical of boreal forests. These birch stands are considered to be relictual populations that have persisted since the end of the Wisconsin glaciation, when regional flora was more boreal in nature...
