Tracing the sources of phosphorus along the salinity gradient in a coastal estuary using multi-isotope proxies

Eutrophication in coastal water has compromised ecosystem services. Identification of phosphorus (P) sources and their load contributions are required for the development of effective nutrient management plans. In this research, multi-isotope proxies …

Microbial Source Tracking in the Love Creek Watershed, Delaware (USA)

Fecal contamination of waterways in Delaware pose an ongoing problem for environmental and public health. For monitoring efforts, *Enterococcus* has been widely adopted by the state to indicate the presence of fecal matter from warm-blooded animals …

Critical comparison of molecular methods for detection and enumeration of the harmful algal species, Heterosigma akashiwo, in environmental water samples

Molecular methods such as quantitative real-time PCR (qPCR) and sandwich hybridization assay (SHA) enable a more rapid and specific enumeration of harmful algal species compared to microscopic cell counts. Integrating these methods into routine …

Community-Level and Species-Specific Associations between Phytoplankton and Particle-Associated Vibrio Species in Delaware's Inland Bays

Vibrio species are an abundant and diverse group of bacteria that form associations with phytoplankton. Correlations between Vibrio and phytoplankton abundance have been noted, suggesting that growth is enhanced during algal blooms or that …

Effects of growth phase, diel cycle and macronutrient stress on the quantification of Heterosigma akashiwo using qPCR and SHA

The development of molecular probe technologies over the last several decades has enabled more rapid and specific identification and enumeration of phytoplankton species compared to traditional technologies, such as light microscopy. Direct …

Comparison of sandwich hybridization assay and quantitative PCR for the quantification of live and preserved cultures of Heterosigma akashiwo (Raphidophyceae)

In this study, we directly compared two molecular techniques, sandwich hybridization assay (SHA) and quantitative PCR (qPCR), for quantifying laboratory cultures of the ichthyotoxic raphidophyte Heterosigma akashiwo. To maximize comparisons, all …
