- Abstract
- Estuaries are highly dynamic and productive environments. A clear understanding of how phytoplankton respond to spatiotemporal dynamics is necessary to ensuring the health and sustainability of these ecosystems. Over the span of a year, we investigated the interactions between biotic and abiotic factors within the eutrophic Neuse River Estuary (NRE). Through metatranscriptomic sequencing in combination with other water quality measurements, we show that there are different metabolic strategies deployed along the NRE, and nitrogen availability is the main driving factor for such divergence. In the upper estuary, phytoplankton express more transcripts of genes for synthesis of cellular components and carbon metabolism whereas in the lower estuary transcripts allocated to nutrient metabolism and transportation were more highly expressed. We advocate for the use of molecular sequencing approaches to complement coastal water quality monitoring programs as a way to examine microbial community dynamics in response to changing environmental conditions.
