The crawfish enterprise of South Louisiana is shown to haveexpanded as much as 18-fold since the 1950's. It is estimated(1973) that there are about 44,000 acres of managed crawfish ponds.Of the 334 ponds identified and mapped in the thesis, 231 are classedas open ponds, 45 as rice field ponds, and...

Successful host cell colonization by the Q fever pathogen, Coxiella burnetii, requires translocation of effector proteins into
the host cytosol by a Dot/Icm type 4B secretion system (T4BSS). In Legionella pneumophila, the two-component system (TCS)
PmrAB regulates the Dot/Icm T4BSS and several additional physiological processes associated with pathogenesis. Because PmrA...

Coastal upwelling regimes are some of the most productive ecosystems in the ocean but are also among the most vulnerable to ocean acidification (OA) due to naturally high background concentrations of CO₂. Yet our ability to predict how these ecosystems will respond to additional CO₂ resulting from anthropogenic emissions is...

Many different models and mechanisms of water imbibition into soil have been described in the literature. Theoretical equations based on those models exist to predict how water will flow in porous media. These models can be useful, but have their weaknesses. Research on imbibition and infiltration into soils has mostly...

The objectives of this study were to determine the extent of absorption of functionalized
single-wall carbon nanotubes (SWCNTs) across the gut epithelial cells in Daphnia magna.
Several microscopic techniques were utilized, including micro-Raman spectroscopy, high-resolution
transmission electron microscopy (HRTEM) and selective area diffraction (SAD). In an
effort to examine the...

We investigated dissolved methane distributions along a 6 km transect crossing active seep sites at 40 m water depth in the central North Sea. These investigations were done under conditions of thermal stratification in summer (July 2013) and homogenous water column in winter (January 2014). Dissolved methane accumulated below the...

Although geodetic measurements of interseismic deformation in interior Tibet suggest slow
strain accumulation, active slip along the right-lateral Gyaring Co Fault is suggested to be between 8

Hypoxia is a naturally occurring phenomenon that happens seasonally off the Oregon coast. As a consequence, there has been a great deal of research focused around analyzing the strength and duration of the hypoxic event during the summer season. This paper, however, takes an innovative approach by looking at the...

OBJECTIVE: Multidimensional Treatment Foster Care (MTFC) has been found to reduce delinquency among girls in juvenile justice through 2-year follow-up. Given that such girls are at elevated risk for suicide and depression into adulthood, we tested MTFC effects on long term trajectories of suicidal ideation and depressive symptoms.
METHOD: Girls...

This research examines the effect of recent landownership changes and new management stewardship
mechanisms (e.g., forest certification and working forest conservation easements) on disturbance rates in Maine
forests. We quantify forest disturbance rates between 2000 and 2007 and forest cover type composition in 2007,

Ecosystems are shaped by processes occurring and interacting over multiple
temporal and spatial scales. Theory suggests such complexity can be simplified by focusing on
processes sharing the same scale as the pattern of interest. This scale-dependent approach to
studying communities has been challenged by multiscale meta-ecosystem theory, which
recognizes that...

Variable ocean conditions can greatly impact lower trophic level prey assemblages in marine ecosystems, with effects propagating up to higher trophic levels. Our goal was to better understand how varying ocean conditions influence diets and niche overlap among a suite of low- to mid trophic level predators. We studied the...

Chromosome segregation relies on coordinated activity of a large assembly of proteins, the kinetochore interaction network (KIN). How conserved the underlying mechanisms driving the epigenetic phenomenon of centromere and kinetochore assembly and maintenance are remains unclear, even though various eukaryotic models have been studied. More than 50 different proteins, many...
