Moreover, previous studies have shown that phytoplankton
and submerged macrophytes can rapidly remove nutrients from
the water column (Zhang et al., 2011), and the over-enrichment
of coastal ecosystems can rarely be detected through direct measurements
of the water column nutrient concentrations. Thus, it
is necessary to identify proper bioindicators for the evaluation of
the influence of nutrient loading originating from human activities
on seagrass meadows.
