Community Structure and Production of the Macrobenthos on Four Artificial Reefs in the Mississippi Sound in Relation to Substrate and Profile Type
… used to construct MS artificial reefs include oyster shell and cement rubble. Two types of reef architecture used include high profile breakwater and low profile submerged structures. This study compared the benthic biota associated with oyster shell and cement rubble substrates among four …

Epifaunal assemblage of a newly established oyster reef with two substrates
An artificial oyster reef constructed in Boca Ciega Bay, off of the War Veteran's Memorial Park, St. Petersburg, Florida, in 2005, was used to compare a mined shell material to the typical oyster shell substrate used in artificial reef projects as an alternative substrate and cultch material. Half …

Identifying inundation-driven effects among intertidal Crassostrea virginica in a commercially important Gulf of Mexico estuary
… on daily inundation and exposure. The eastern oyster Crassostrea virginica is an economically and biologically important sessile intertidal species ranging from Canada to the Gulf of Mexico. Declines and changes in distribution of oyster populations has forced commercial harvesting to spread …

NAKED GOBIES (GOBIOSOMA BOSC) AS INDICATORS OF OYSTER REEF RESTORATION SUCCESS
… are the most abundant resident fish on oyster reefs in the Chesapeake Bay and serve as a critical trophic link between the benthic and pelagic communities. Their response to oyster restoration may therefore be a useful indicator of ecosystem functioning. Experiments were conducted from …

FROM ALGAE BLOOMS TO INTERIOR SYSTEMS: SEAWEED-BASED MATERIAL SYSTEMS AND DIGITAL FABRICATION STRATEGIES FOR SUSTAINABLE ARCHITECTURE
… Waste Cladophora algae, together with oyster shell, alginate, and hemp fibers, are transformed into a biodegradable, low-carbon material. Digital fabrication techniques, including 3D printing and parametrically designed systems with mold casting, are used to shape these composites into …

Wave Mechanics in Constructed Oyster Reefs and the Design of Nature-Based Coastal Adaptation
… great interest in the potential of constructed oyster reefs (CORs) to function as nature-based coastal protection infrastructure, but most projects to-date are designed primarily for wave attenuation and fail to consider both the environmental conditions necessary for long-term oyster reef …

Improved Management of Acid Sulfate Soils for Rice Production in Casamance, Senegal
… soil treatments – agricultural lime, pulverized oyster shell, biochar, and control (no amendment) – in flat and raised beds. Plots amended with lime and shell materials had increased soil pH, base saturation, Ca, and cation exchange capacity. Meanwhile, biochar elevated particulate organic matter …

Resident Benthic Fishes of Artificial Reefs in the Mississippi Sound: Effects of Habitat Relief and Subregion
… high profile reefs relative to low profile oyster shell reefs. Subregion also appeared to effect poorer condition in the eastern subregion. Diet volume was low in <em>Gobiesox strumosus </em>from high profile reefs, and contents differed across both reef types and subregions. Differences in …

Native And Invasive Competitors Of The Eastern Oyster Crassostrea Virginica In Mosquito Lagoon, Florida
… about the sources of juvenile and adult oyster mortality must be answered. Potential causes of Crassostrea virginica mortality in the Indian River Lagoon system include sediment loads, competition, predation, and disease. My research focused on the interactions between oysters and the …

Role of hydrocarbon pollutants, salinity, tidal height, bioenergetics and competition in colonization of oyster reefs by commensal assemblages
… height, bioenergetics and competition on the oyster reef fauna were studied. Dried oyster shell was exposed to crude oil in the laboratory and plastic trays filled with control and oil-exposed shell were then deployed at two locations, in two seasons and at two tidal levels, with immersion …

The Development of a Fluid Consistency Transducer
… (d) a sphere in translational motion, (e) an 'oyster' shell consisting of two circular plates joined at the periphery with a gap in between, the two plates vibrating in phase in the fundamental mode, (f) a torsionally resonant rod. This was found to interact sufficiently well without further …

The Effects of Ocean Acidification on Multiple Life History Stages of the Pacific Oyster, Crassostrea gigas: Implications for Physiological Trade-offs
… effects of ocean acidification on the Pacific oyster, <italic>Crassostrea gigas</italic>. Oysters are sedentary and inhabit a naturally variable environment (the intertidal zone) and thus may be pre-adapted to withstand rapid environmental change. Oysters and similarly sedentary organisms are …

Soil Management for Improved Rice Production in Casamance, Senegal
… with each planting method: biochar and crushed oyster shells, alone and in combination. An untreated control was included in the experiment. All plots were fertilized. Treatment effects on soil properties and yield were compared in a split-plot design. Plant tissue was sampled for elemental …

Kongo to Kings County
… as parts of spiritual caches, as well as an oyster shell and a hand-stitched baby shoe. While the relevance of bones in a cache are yet unknown (Leone 2005:226), shells are known to be symbols of cyclical life and prosperity in the Kongo mindset (MacGaffey 1986:117), and serve as a reminder …
