Spatial and temporal shifts in the diet of the barnacle Amphibalanus eburneus within a subtropical estuary.

ABSTRACT: The success of many sessile invertebrates in marine benthic communities is linked to their ability to efficiently remove suspended organic matter from the surrounding water column. To investigate the diet of the barnacle Amphibalanus eburneus, a dominant suspension feeder within the Indian River Lagoon (IRL) of central Florida, we compared the stable isotopes ratios (δ¹³C and δ¹⁵N) of barnacle tissue to those of particulate organic matter (POM). Collections were carried out quarterly for a year from 29 permanent sites and at sites impacted by an Aureoumbra lagunensis bloom. δ¹³C and δ¹⁵N values of Amphibalanus eburneus varied across sites, but δ¹⁵N was more stable over time. There was a range of δ¹⁵N val
