Douglas-fir: The Genus Pseudotsuga

Creator:: Lavender, Denis P. and Hermann, Richard K.
Abstract:: Douglas-fir (Pseudotsuga menziesii) has a wide distribution in North America and is one of the tree species most widely distributed outside its natural range. The species has been introduced to Europe, New Zealand, South America, and elsewhere around the world. At present, Douglas-fir is an accepted and integral part of...

Diversity and distribution of anostomoid fishes (Teleostei: Characiformes) throughout the Guianas

Creator:: Sidlauskas, Brian L. and Vari, Richard P.
Abstract:: Diversité et distribution des poissons anostomoides (Teleostei, Characiformes) dans les Guyanes. Cinquante-six espèces, soit approximativement 20% des Characiformes de la superfamille des Anostomidea (familles des Anostomidae, Chilodontidae, Curimatidae et Prochilodontidae), fréquentent les eaux douces de la Guyane française, du Guyana et du Suriname bien que ces régions ne recouvrent qu’environ...

Atomic-scale structural evolution of Ta-Ni-Si amorphous metal thin films

Creator:: Oleksak, Richard P., Devaraj, Arun, and Herman, Gregory S.
Abstract:: We investigated the thermal stability of a new ternary amorphous metal thin film, Ta₂.₄Ni₂.₂Si, and assessed its suitability as a Cu diffusion barrier for semiconductor device applications. Transmission electron microscopy was coupled with atom probe tomography to provide a detailed understanding of the atomic-scale evolution of both structure and composition...

Gleaning Unexpected Fruits from Hard-Won Synthetases: Probing Principles of Permissivity in Non-canonical Amino Acid–tRNA Synthetases

Creator:: Cooley, Richard B., Karplus, P. Andrew, and Mehl, Ryan A.
Abstract:: The site-specific incorporation of non-canonical amino acids (ncAAs) into proteins is an important tool for understanding biological function. Traditionally, each new ncAA targeted requires a resource-consuming process of generating new ncAA aminoacyl tRNA synthetase/tRNACUA pairs. However, the discovery that some tRNA synthetases are “permissive,” in that they can incorporate multiple...

Multivariate statistical analysis and partitioning of sedimentary geochemical data sets: General principles and specific MATLAB scripts

Creator:: Pisias, Nicklas G., Murray, Richard W., and Scudder, Rachel P.
Abstract:: Multivariate statistical treatments of large data sets in sedimentary geochemical and other fields are rapidly becoming more popular as analytical and computational capabilities expand. Because geochemical data sets present a unique set of conditions (e.g., the closed array), application of generic off-the-shelf applications is not straightforward and can yield misleading...

Comparison of Disturbed and Undisturbed Soil Core Methods to Estimate Nitrogen-Mineralization Rates in Manured Agricultural Soils

Creator:: Moberg, Dean P., Johnson, Richard L., and Sullivan, Dan M.
Abstract:: Ion exchange resin/soil cores are a common in situ approach to estimating soil nitrogen (N) mineralization rates. However, no studies compare the two common methods of core preparation (disturbed and undisturbed). The objective of our study was to compare N mineralized and soil temperature in disturbed versus undisturbed cores of...

Arrhinolemur scalabrinii Ameghino, 1898, of the late Miocene - a taxonomic journey from the Mammalia to the Anostomidae (Ostariophysi: Characiformes)

Creator:: Bogan, Sergio, Sidlauskas, Brian, Vari, Richard P., and Agnolin, Federico
Abstract:: The fossil species Arrhinolemur scalabrinii, which was described from late Miocene deposits of Entre Ríos, Argentina, is reevaluated. Whereas the species was originally placed in the Primates (Mammalia) and later made the unique member of the order Arrhinolemuroidea within the Mammalia, our analysis indicates that the specimen is rather a...

New species of Cyphocharax (Ostariophysi: Characiformes: Curimatidae) from Suriname and French Guiana and a discussion of curimatid diversity on the Guiana Shield

Creator:: Vari, Richard P., Sidlauskas, Brian L., and Le Bail, Pierre-Yves
Abstract:: Cyphocharax biocellatus, a species of curimatid characiform apparently endemic to the Marowijne River/Fleuve Maroni system in Suriname and French Guiana, and the Maim River basin in French Guiana is described as new. The new species is diagnosed from congeners based on meristic and morphometric features and details of pigmentation of...

Mortalities of Eastern and Pacific Oyster Larvae Caused by the Pathogens Vibrio coralliilyticus and Vibrio tubiashii

Creator:: Richards, Gary P., Watson, Michael A., Needleman, David S., Church, Karlee M., and Häse, Claudia C.
Abstract:: Vibrio tubiashii is reported to be a bacterial pathogen of larval Eastern oysters (Crassostrea virginica) and Pacific oysters (Crassostrea gigas) and has been associated with major hatchery crashes, causing shortages in seed oysters for commercial shellfish producers. Another bacterium, Vibrio coralliilyticus, a well-known coral pathogen, has recently been shown to...

Irrigation Frequency during Container Production Alters Rhododendron Growth, Nutrient Uptake, and Flowering after Transplanting into a Landscape

Creator:: Scagel, Carolyn F., Bi, Guihong, Bryla, David R., Fuchigami, Leslie H., and Regan, Richard P.
Abstract:: One deciduous cultivar of Rhododendron L., Gibraltar (AZ), and two evergreen cultivars, P.J.M. Compact (PJM) and English Roseum (ER), were grown in containers for 1 year to determine the effects of irrigation frequency during container production on plant performance the next spring when the plants were transplanted into the landscape....
