Note
Estuarine trophic transfer depends on many biological, chemical, and hydrodynamic factors, among which are size, biodiversity and ecology of the resident populations. In the Indian River Lagoon (IRL), Florida, USA, a biogeographically transitional area between temperate and tropical zones, we hypothesized that measuring the size fractions of planktonic chlorophyll as a proxy for microalgal biomass was insufficient to determine the trophic transfer potential and ecological preference of microalgal biodiversity.
