Using sensitivity analysis in model calibration efforts
Claire R. Tiedeman, Mary C. Hill
2003, Book chapter, Proceedings of the International Workshop on Uncertainty, Sensitivity, and Parameter Estimation for Multimedia Environmental Modeling
In models of natural and engineered systems, sensitivity analysis can be used to assess relations among system state observations, model parameters, and model predictions. The model itself links these three entities, and model sensitivities can be used to quantify the links. Sensitivities are defined as the derivatives of simulated quantities...

Giant submarine canyons: Is size any clue to their importance in the rock record?
William R. Normark, Paul R. Carlson
2003, GSA Special Papers (370) 175-190
Submarine canyons are the most important conduits for funneling sediment from continents to oceans. Submarine canyons, however, are zones of sediment bypassing, and little sediment accumulates in the canyon until it ceases to be an active conduit. To understand the potential importance in the rock record of any given submarine...
La mondialisation des poussieres, les vents transportent, d'un continent a l'autre, des poussieres, mai aussi des micro-organismes et des substances toxiques. Ces "passagers clandestins" pourraient transporter des maladies et modifier les ecosystems
D. Griffin, C. Kellogg, V. Garrison, E. Shinn
2003, Pour la Science (309) 79-85
Un tour d'horizon de la littérature scientifique révèle que de nombreux champs d'investigation sont jugés dignes d'intérêt de façon périodique : certaines idées sont à la mode pour un temps, puis sombrent dans l'oubli, avant de refaire surface comme si elles n'avaient jamais été émises. L'aérobiologie, c'est-à-dire l'étude des micro-organismes,...
Influence of climate on deep-water clastic sedimentation: application of a modern model, Peru-Chile Trough, to an ancient system, Ouachita Trough
N. Terence Edgar, C. Blaine Cecil
2003, Climate Controls on Stratigraphy: SEPM Special Publication (77) 185-191
Traditionally, an abrupt and massive influx of siliciclastic sediments into an area of deposition has been attributed to tectonic uplift without consideration of the influence of climate or climatic change on rates of weathering, erosion, transportation, and deposition. With few exceptions, fluvial sediment transport is minimal in both extremely arid...

Quantifying migratory delay: A new application of survival analysis
Theodore Castro-Santos, Alex Haro
2003, Canadian Journal of Fisheries and Aquatic Sciences (60) 986-996
Statistical techniques commonly used in fish passage research fail to adequately quantify delays incurred at obstacles, or the effects of modifications to those obstacles on passage rates. Analyses of telemetry data describing these effects can be misleading, particularly when passage route of some individuals is not established (e.g., because of...

Evolution of trophic transmission in parasites: Why add intermediate hosts?
Marc Choisy, Sam P. Brown, Kevin D. Lafferty, Frederic Thomas
2003, American Naturalist (162) 172-181
Although multihost complex life cycles (CLCs) are common in several distantly related groups of parasites, their evolution remains poorly understood. In this article, we argue that under particular circumstances, adding a second host to a single-host life cycle is likely to enhance transmission (i.e., reaching the target host). For instance,...
