Growth and chemotaxis of nematodes reduced upon exposure to Third Fork Creek surface water

Environmental Sciences Europe, 34(1).

By: C. Gerald *, B. Deshazo*, H. Patterson* & P. Spence* 

Contributors: C. Gerald *, B. Deshazo*, H. Patterson* & P. Spence* 

author keywords: Nematode; Third Fork Creek; Biological model; Ecotoxicology; Freshwater
TL;DR: Exposure to Third Fork Creek surface water will inhibit the growth and chemotaxis of C. elegans, a non-parasitic, soil and aquatic dwelling nematodes used in a plethora of human diseases and exposure research but can be utilized as an environmental indicator of water quality impairment.

Using Caffeine as a Water Quality Indicator in the Ambient Monitoring Program for Third Fork Creek Watershed, Durham, North Carolina

Environmental Health Insights, 9.

By: P. Spence* 

Contributors: P. Spence* 

author keywords: caffeine; ecosystems services; fecal coliform; stormwater; urban watersheds
TL;DR: It is recommended that the concentration of caffeine and other organic waste contaminants are determined during storm and nonstorm periods and caffeine is monitored regularly with traditional water quality indicators to evaluate the health of Third Fork Creek watershed.

2013 journal article

Effects of nitrogen inputs on freshwater wetland ecosystem services - A Bayesian network analysis

Journal of Environmental Management, 124, 91–99.

By: P. Spence*  & S. Jordan*

Contributors: P. Spence*  & S. Jordan*

author keywords: Freshwater wetlands; Nitrogen removal; Water quality; Nitrous oxide; Ecosystem services; Bayesian Belief Networks
MeSH headings : Bayes Theorem; Ecosystem; Empirical Research; Fresh Water / chemistry; Nitrogen / analysis; Wetlands
TL;DR: Even though the BBN has a very low error rate indicating a high predictive accuracy, additional testing and larger training and testing datasets would increase confidence in the model's ability to provide robust predictions and to reduce the uncertainty resulting from an incomplete dataset and knowledge gaps regarding the interactions between N2O emissions and outflow water quality.
