The Society for Freshwater Science (formerly "NABS" back in my studenthood) annual meeting is in Raleigh this year, June 4-8, immediately before our NANFA convention in MO: < http://sfsannualmeeting.org/agenda.cfm >
It's a pricey conference < http://sfsannualmeet...egistration.cfm> but there's a significant discount if you register by March 24.
Anyway, here's an interesting article from the latest issue of the SFS Journal Freshwater Science on algae vs vascular aquatic plants in northern FL springs. These authors suggest that periodic flow reversals in the springs caused by floods from blackwater rivers are a significant factor in the overgrowth of filamentous algae in springs that were formerly dominated by rooted plant beds. Nutrient enrichment from urban and agricultural lands is not the only factor at play.
