TL;DR: Managers should consider whether balanced control of N and P will most effectively reduce HABs along the freshwater-marine continuum, supported by studies indicating that biological N fixation cannot always meet lake ecosystem N needs, and that anthropogenic N andP loading has increased dramatically in recent decades.

TL;DR: A mechanistic conceptual model was constructed by combining nutrient cycling and CBAD observations from a spectrum of lakes to assess N cycling interactions with CyanoHABs, and supported with CBAD data from a Microcystis bloom in Maumee Bay, Lake Erie, during summer 2015.

TL;DR: In this paper, intact sediment cores were incubated in a continuous-flow system with 15N enrichments to compare N consumption and efflux pathways within and near seagrass beds in St Joseph Bay, Florida.

TL;DR: Examination of seagrass and epiphyte response to field manipulations of nutrients and grazing in Big Lagoon, FL, USA found effects of fertilization and grazing showed both similarities and differences in comparison to other studies from the same and different locations, raising the question about how predictable and informative the responses of individual seagRass characteristics are for discerning the relative, long-term influence of these factors.

TL;DR: The role of internal N recycling in the water column to support bloom maintenance is not as well understood as well as the physiological importance of nitrogen (N) in supporting bloom biomass and toxin production is established as discussed by the authors .
