Nitrogen contamination of surficial aquifers - A growing legacy
Larry J. Puckett, Anthony J. Tesoriero, Neil M. Dubrovsky
2011, Environmental Science & Technology (45) 839-844
The virtual ubiquity of fertilizer-fed agriculture, increasing over several decades, has become necessary to support the global human population. Ironically, widespread use of nitrogen (N) has contaminated another vital resource: surficial fresh groundwater. Further, as nitrous oxide (N2O) is a potent greenhouse gas, anthropogenic manipulation of...

Radiotelemetry to estimate stream life of adult chum salmon in the McNeil River, Alaska
Joshua Peirce, Edward O. Otis, Mark S. Wipfli, Erich H. Follmann
2011, North American Journal of Fisheries Management (31) 315-322
Estimating salmon escapement is one of the fundamental steps in managing salmon populations. The area-under-the-curve (AUC) method is commonly used to convert periodic aerial survey counts into annual salmon escapement indices. The AUC requires obtaining accurate estimates of stream life (SL) for target species. Traditional methods for estimating SL (e.g.,...
