Thesis: Effects of nutrient enrichment on alkaline phosphatase activity and nitrogen fixation potential in stream periphyton.
David refined a nutrient-diffusing substrate method and made some fascinating discoveries about the sensitivity of different indicators of nutrient limitation and microbial activity in streams, publishing his thesis results in J-NABS in 2009. He is currently a lecturer in the Department of Biology at the University of Houston.
