Typologies of intimate violence are part of an emerging paradigm towards a multifaceted, multi-theoretical approach to understanding the causes and effects of intimate violence. For this new paradigm to be implemented into research and practice, there are several gaps in the knowledge base that must be addressed. In particular, there...
The oxygen concentration in a stream is an important
parameter of water quality. Changes in oxygen concentrations
can affect various stream organisms including fish.
Foresters have become concerned with predicting the impacts
of forest activities on oxygen levels in streams. Slash,
which accumulates in streams as a result of harvesting...
Geotextiles are synthetic fabrics which may be substituted for
graded aggregate to protect ocean and coastal structures from erosion
and soil instability adjacent to the structure. They are commonly
used as a filter and as a structural membrane between an undisturbed
sediment surface below and an erosion resistant coarse aggregate...
Shewanella oneidensis MR-1 is a gram-negative, facultative anaerobic bacteria with the capability of dissimilatory metal reduction. The ability of the organism to reduce a wide range of solid metal-oxides during anaerobic respiration makes it an ideal candidate for the powering of microbial fuel cells (MFCs), which capture the electrons discharged...
The El Salvador porphyry copper deposit in the Indio Muerto district of northern Chile has been geologically investigated for more than 60 years and provides one of the best bases for understanding similar environments of ore formation elsewhere in the world. Fourteen new zircon U/Pb isotopic ages obtained via in...
Nitrosomonas sp. strain AL212 is an obligate chemolithotrophic ammonia-oxidizing bacterium (AOB) that was originally isolated in 1997 by Yuichi Suwa and colleagues. This organism belongs to Nitrosomonas cluster 6A, which is characterized by sensitivity to high ammonia concentrations, higher substrate affinity (lower K[subscript m]), and lower maximum growth rates than...
Understanding larval bivalve responses to variable regimes of seawater carbonate chemistry requires realistic quantification of physiological stress. Based on a degree-day modeling approach, we developed a new metric, the ocean acidification stress index for shellfish (OASIS), for this purpose. OASIS integrates over the entire larval period the instantaneous stress associated...
ABSTRACT: Sedimentary habitats are complex associations of biotic, chemical, and physical processes
comprising ‘ecosystem function’. The relative importance of these processes to biogeochemical
cycling in highly reactive, permeable sediments remains poorly understood. We report results
from several field experiments in a muddy-sand intertidal flat dominated by 2 functionally different
types...
Bioturbating infauna significantly modify reaction and transport processes in permeable sediments, though most studies to date are limited in the scope of species examined. We conducted a comparative field study measuring density-dependent effects of six common bioturbating species on porewater advection and biogeochemistry, across three intertidal permeable sediment habitats. The...

Expert advisory systems for agricultural pest management control offer the means to capitalize on the wealth of information that is currently tied up in research laboratories and human experts' minds. The ideal system would blend knowledge from three sources - human experts, dynamic simulation models, and historical databases - to...
Disease, overharvesting, and pollution have impaired the role of bivalves on coastal ecosystems, some to the point of functional extinction. An underappreciated function of many bivalves in these systems is shell formation. The ecological significance of bivalve shell has been recognized; geochemical effects are now more clearly being understood. A...
Oyster shell is a crucial component of healthy oyster reefs. Shell planting has been a main component of oyster restoration efforts in many habitats and has been carried out on scales from individual and grassroots efforts to multiagency efforts across entire estuaries. However, the cycling and lifetime of the shell...

Nitrosomonas sp. Is79 is a chemolithoautotrophic ammonia-oxidizing bacterium that belongs to the family Nitrosomonadaceae within the phylum Proteobacteria. Ammonia oxidation is the first step of nitrification, an important process in the global nitrogen cycle ultimately resulting in the production of nitrate. Nitrosomonas sp. Is79 is an ammonia oxidizer of high...
Acidified waters are impacting commercial oyster
production in the U.S. Pacific Northwest, and favorable
carbonate chemistry conditions are predicted to become
less frequent. Within 48 h of fertilization, unshelled Pacific
oyster (Crassostrea gigas) larvae precipitate roughly 90% of
their body weight as calcium carbonate. We measured stable
carbon isotopes in...

We tested the role of benthic infaunal functional diversity in regulating the biogeochemistry of nearshore sediments using laboratory microcosms. Single and multispecies assemblages of deposit-feeding polychaetes (Clymenella torquata, Spio setosa, and Leitoscoloplos fragilis) were used, and fluxes of oxygen and phosphate, as well as profiles of oxygen and pH in...

The brine shrimp (Artemia salina) bioassay was used to screen 211 methanol extracts from 128 species of Pacific Northwest plants in search of general cytotoxic activity. Strong toxicity (LC₅₀ < 100 µg/ml) was found for 17 extracts from 13 species, with highest activity observed for Angelica arguta roots at <10...
In the mid-2000s the U.S. west coast oyster industry experienced several years of significant production failures. This industry has been referred to as the “canary in a coal mine” for ocean acidification (OA). Industry-led collaboration with university and government scientists identified a relationship between elevated carbon dioxide in seawater and...
