Gary H. Heinz, Katherine R. Stebbins, Jon D. Klimstra, David J. Hoffman
2009, Environmental Toxicology and Chemistry (28) 1425-1428
We developed a simplified and highly accurate method for correcting contaminant concentrations in eggs for the moisture that is lost from an egg during incubation. To make the correction, one injects water into the air cell of the egg until overflowing. The amount of water injected corrects almost perfectly for...
Identifying baldcypress-water tupelo regeneration classes in forested wetlands of the Atchafalaya Basin, Louisiana

2009, Wetlands (29) 809-817
Baldcypress-water tupelo (cypress-tupelo) swamps are critically important coastal forested wetlands found throughout the southeastern U.S. The long-term survival and sustainability of these swamp forests is unknown due to large-scale changes in hydrologic regimes that prevent natural regeneration following logging or mortality. We used NWI wetland maps and remotely sensed hydrologic...

The influence of use-related, environmental, and managerial factors on soil loss from recreational trails
Nathaniel D. Olive, Jeffrey L. Marion
2009, Journal of Environmental Management (90) 1483-1493
Recreational uses of unsurfaced trails inevitably result in their degradation, with the type and extent of resource impact influenced by factors such as soil texture, topography, climate, trail design and maintenance, and type and amount of use. Of particular concern, the loss of soil through erosion is generally considered...
Alternative substrates for culturing the freshwater oligochaete Lumbriculus variegatus
P. J. Lasier
2009, North American Journal of Aquaculture (71) 87-92
The freshwater oligochaete Lumbriculus variegatus is tank cultured to provide organisms for aquatic habitat assessments and regeneration research and to produce a clean source of live food for aquarium fishes. Shredded paper is the typical substrate in small-scale culture of L variegants, however, the effort needed to separate large...
Analysis of capture–recapture models with individual covariates using data augmentation
J. Andrew Royle
2009, Biometrics (65) 267-274
I consider the analysis of capture–recapture models with individual covariates that influence detection probability. Bayesian analysis of the joint likelihood is carried out using a flexible data augmentation scheme that facilitates analysis by Markov chain Monte Carlo methods, and a simple and straightforward implementation in freely available software. This approach...
Elevated CO2 stimulates marsh elevation gain, counterbalancing sea-level rise
J.A. Langley, K.L. McKee, Donald R. Cahoon, J. A. Cherry, J.P. Megonigala
2009, Proceedings of the National Academy of Sciences (106) 6182-6186
Tidal wetlands experiencing increased rates of sea-level rise (SLR) must increase rates of soil elevation gain to avoid permanent conversion to open water. The maximal rate of SLR that these ecosystems can tolerate depends partly on mineral sediment deposition, but the accumulation of organic matter is equally important for many...
The Stephen H. Long Expedition (1819?1820), Titian R. Peale?s field illustrations, and the lost holotypes of the North American shrews Sorex brevicaudus Say and Sorex parvus Say (Mammalia: Soricidae) from the Philadelphia Museum

Hydrology and simulation of ground-water flow in the Tooele Valley ground-water basin, Tooele County, Utah
Bernard J. Stolp, Lynette E. Brooks
2009, Scientific Investigations Report 2009-5154
Ground water is the sole source of drinking water within Tooele Valley. Transition from agriculture to residential land and water use necessitates additional understanding of water resources. The ground-water basin is conceptualized as a single interconnected hydrologic system consisting of the consolidated-rock mountains and adjoining unconsolidated basin-fill valleys. Within the...
