Twenty-eight tidal creeks were sampled along the South Carolina coast in the summer of 1995 to determine the levels of sediment trace metal contamination associated with different types and varying levels of human development in their watersheds. The particle size and total organic carbon (TOC) content of creek sediments in developed watersheds (i.e., industrial, urban, and suburban) were simil...

Landscape features and life-history traits affect gene flow, migration and drift to impact on spatial genetic structure of species. Understanding this is important for managing genetic diversity of threatened species. This study assessed the spatial genetic structure of the rare riparian Grevillea sp. Cooljarloo (Proteaceae), which is restricted to a 20 km2 region impacted by mining in the nort...

BENFER, N.P., KING, B.A. and LEMCKERT, C.J., 2007. Salinity observations in a subtropical estuarine system on the Gold Coast, Australia. Journal of Coastal Research, SI 50 (Proceedings of the 9th International Coastal Symposium), 646 – 651. Gold Coast, Australia, ISSN 0749.0208 Saltwater Creek and Coombabah Creek are branches of the Coomera River estuary situated within the subtropical Gold Coa...

A combination of transplant experiments and provision of recruitment surfaces has been initiated to determine the degree to which differences in sponge diversity and species composition at two Twin Cays sites, Hidden Creek and Sponge Haven, reflect differences in abiotic factors, ecological interactions, and recruitment history. This report contains the first stages of this project. The Hidden ...

Parasites of the fathead minnow, Pimephales promelas, were examined in fish collected from Elk Creek (40.88534 degrees N, 96.83366 degrees W) and West Oak Creek (40.90821 degrees N, 96.81432 degrees W), Lancaster County, Nebraska. These 2 streams are part of the Salt Valley watershed and flow together approximately 2 km downstream from the collection sites to form Oak Creek. This study examined...

Rotaviruses were concentrated from 8-liter samples of raw domestic sewage and sewage-polluted creek water by adsorption to and elution from positively charged microporous filters (Zeta Plus 60S), followed by ultracentrifugation of the filter eluates. Indirect immunofluorescence and direct immunoperoxidase methods allowed detection and enumeration of rotavirus in 6 (20.6%) of 29 sewage samples a...

The next major earthquake to strike the ~7 million residents of the San Francisco Bay Area will most likely result from rupture of the Hayward or Rodgers Creek faults. Until now, the relationship between these two faults beneath San Pablo Bay has been a mystery. Detailed subsurface imaging provides definitive evidence of active faulting along the Hayward fault as it traverses San Pablo Bay and ...

The bioefficacy of a commercial formulation of temephos, Creek against Aedes aegypti larvae was studied in the laboratory. Earthen jars were filled with 10 L tap water each. One g of temephos (Creek) sand granule formulation was added into each earthen jar as recommended by the manufacturer. The final test concentration of Creek was 1 mg a.i./L. One earthen jar was filled with 10 L tap water an...

perylene and penta-aromatic hydrocarbons were determined in sediments as part of a study that was dedicated to the aquatic ecosystem of oginigba creek (southern nigeria) in order to carry out a critical corroboration of occurrence and diagenetic evolution of perylene in the sediments of the creek. the results show that the annual mean levels of perylene ranged from 396.27– 507.19 mg/g dry wei...
