Carbon isotope composition of fatty acids and sterols in the scleractinian coral Turbinaria reniformis: Effect of light and feeding
Carbon isotope composition fatty acids sterols the scleractinian coral Turbinaria reniformis: Effect of light and feeding
2014/4/17
The effect of auto- and heterotrophy on the carbon isotope composition (d13C) of fatty acids (FA) and sterols was studied in the scleractinian coralTurbinaria reniformis. Colonies were maintained in a...
Composition, production, and loss of carbohydrates in subtropical shallow subtidal sandy sediments: Rapid processing and long-term retention revealed by 13 C-labeling
Composition production loss of carbohydrates subtropical shallow subtidal sandy sediments Rapid processing long-term retention revealed by 13 C-labeling
2014/4/16
The composition and production of carbohydrates (mannose, rhamnose, fucose, galactose, glucose, and xylose) and their transfer among sediment compartments (microphytobenthos [MPB], bacteria, and detri...
Exchange between suspended and sinking particles in the northwest Mediterranean as inferred from the organic composition of in situ pump and sediment trap samples
suspended sinking particles northwest Mediterranean as inferred from the organic
2014/4/16
The extent to which sinking particles disaggregate and exchange with surrounding material affects the
efficiency of particulate organic carbon export to the deep sea. In 2003 and 2005, we compared th...
Contrasting the influences of stream inputs and landscape position on bacterioplankton community structure and dissolved organic matter composition in high-elevation lake chains
Contrasting landscape position
2014/4/18
We examined bacterioplankton community composition (BCC; using polymerase chain reaction-based
phylogenetic fingerprinting) and the composition of dissolved organic matter (DOM; using scanning fluoro...
Dispersal limitations and history explain community composition of metaphyton in desert springs of the Bonneville Basin, Utah: A multiscale analysis
Dispersal limitations history metaphyton desert springs Bonneville Basin Utah multiscale analysis
2014/4/18
We examined patterns of metaphyton community composition from 150 sites in spring wetlands of the Bonneville Basin across three spatial scales: valleys, wetlands nested in valleys, and habitat types n...
Nitrification in Mono Lake, California: Activity and community composition during contrasting hydrological regimes
Nitrification in Mono Lake California Activity community composition hydrological regimes
2014/4/18
Rates of nitrification, geochemical variables, and the associated ammonia oxidizer microbial community were investigated in the water column of Mono Lake, California, between August 2002 and August 20...
A time series investigation of the oxygen isotopic composition of dissolved inorganic phosphate in Monterey Bay, California
oxygen isotopic composition dissolved inorganic phosphate Monterey Bay California
2014/5/5
We present a 2-yr time series of the oxygen isotopic composition of dissolved inorganic phosphate (δ18Op) in Monterey Bay, California. δ18Op can serve as a proxy for phosphate utilization because its ...
Nitrogen sources and cycling in the San Francisco Bay Estuary: A nitrate dual isotopic composition approach
Nitrogen sources cycling San Francisco Bay Estuary nitrate dual isotopic composition
2014/5/4
We used the dual isotopic composition of nitrate (δ15N and δ18O) within the estuarine system of San Francisco (SF) Bay, California, to explore the utility of this approach for tracing sources and cycl...
