WebFeb 8, 2016 · In contrast, there is a limited understanding of the interplay between nitrogen, phosphorus and benthic cyanobacterial proliferations in lotic systems. In New Zealand rivers, Phormidium spp. blooms have been associated with elevated nitrogen (ca. >0.1 mg L −1) and low-phosphorus concentrations (c. <0.01 mg L −1; Wood and Young 2011, 2012). WebSep 21, 2016 · Nitrogen (N) pollution of freshwater, estuarine and marine ecosystems is widespread and has numerous environmental and economic impacts.
