A new method was developed for the analysis of natural and synthetic androgenic steroids and their selected metabolites in aquatic environmental matrices using direct large-volume injection (LVI) high performance liquid chromatography (HPLC) tandem mass spectrometry (MS/MS). Method accuracy ranged from 88 to 108% for analytes with well-matched internal standards. Precision,...

Graphical methods for displaying uncertainty are often the most concise and informative way to communicate abstract concepts. Presentation methods currently in use for the display and interpretation of scientific uncertainty are reviewed. Numerous subjective and objective uncertainty display methods are presented, including qualitative assessments, node and arrow diagrams, standard statistical...
Simulations from a regional climate model (RCM) as part of a superensemble experiment were compared with observations of surface meteorological variables over the western United States. The RCM is the Hadley Centre Regional Climate Model, version 3, with improved physics parameterizations (HadRM3P) run at 25-km resolution and nested within the...

Evaluation of a Regional Climate
Little is known about mixing in the abyssal equatorial oceans in spite of its inferred importance for upwelling dense water. Here we present full-depth microstructure turbulence profiles obtained in the equatorial Pacific that show evidence for intense wind-generated abyssal mixing. Mixing was intensified over the bottom 700 m where the...
Dating pelagic clay can be a challenge due to its slow sedimentation rate, post-depositional alteration, and lack of biogenic deposition. Co-based dating techniques have the potential to create age models in pelagic clay under the assumption that the flux of non-detrital Co to the seafloor is spatially and temporally constant,...

This paper reviews the current progress in mathematical modeling of
anti-reflective subwavelength structures. Methods covered include effective medium
theory (EMT), finite-difference time-domain (FDTD), transfer matrix method (TMM), the
Fourier modal method (FMM)/rigorous coupled-wave analysis (RCWA) and the finite
element method (FEM). Time-based solutions to Maxwell’s equations, such as FDTD,
have...
Here we document introns in two Symbiodinium clades that were most likely gained following divergence of this genus
from other peridinin-containing dinoflagellate lineages. Soluble peridinin-chlorophyll a-proteins (sPCP) occur in short and
long forms in different species. Duplication and fusion of short sPCP genes produced long sPCP genes. All short and...
1. Chronic infections may have negative impacts on wildlife populations, yet their effects are difficult to detect in the absence of long-term population monitoring. Brucella abortus, the bacteria responsible for bovine brucellosis, causes chronic infections and abortions in wild and domestic ungulates, but its impact on population dynamics is not...

Ecological niche models can be a useful tool to identify candidate reintroduction sites for endangered
species but have been infrequently used for this purpose. In this paper, we (1) develop activity-specific
ecological niche models (nesting, roosting, and feeding) for the critically endangered California condor
(Gymnogyps californianus) to aid in reintroduction...
