Phytoplankton Assemblages in Selected Freshwaters of New Jersey

MEIYIN WU & YARITZA ACOSTA NJ Monitoring

Higher intensity of HAB events Little information available on freshwater phytoplankton and taxa in New Jersey

Algal bloom from October 2016 in Orange Reservoir, Algal bloom from October 2016 in the Passaic River, NJ. NJ (South Mountain Reservation) Objectives Compile a list of freshwater phytoplankton in New Jersey Understand distribution and abundance of phytoplankton in New Jersey Identify potential toxin-producing cyano taxa
