Mechanistic and statistical models of total Vibrio abundance in the Neuse River Estuary
چکیده انگلیسی


- Presented a new statistical model for Vibrio abundance in the Neuse River Estuary.
- Generated a five-parameter mechanistic model of Vibrio abundance.
- Longest study-period of Vibrio in the Neuse River Estuary.
- Incorporates data from extreme events such as storms, floods, and droughts.

Bacteria in the genus Vibrio are ubiquitous to estuarine waters worldwide and are often the dominant genus recovered from these environments. This genus contains several potentially pathogenic species, including Vibrio vulnificus, Vibrio cholerae, Vibrio parahaemolyticus, and Vibrio alginolyticus. These bacteria have short generation times, as low as 20-30 min, and can thus respond rapidly to changing environmental conditions. A five-parameter mechanistic model was generated based on environmental processes including hydrodynamics, growth, and death rates of Vibrio bacteria to predict total Vibrio abundance in the Neuse River Estuary of eastern North Carolina. Additionally an improved statistical model was developed using the easily monitored parameters of temperature and salinity. This updated model includes data that covers more than eight years of constant bacterial monitoring, and incorporates extreme weather events such as droughts, storms, and floods. These models can be used to identify days in which bacterial abundance might coincide with increased health risks.
