文摘
- •
Echinoid taxa span three benthic trophic levels, suggesting expansion of niches.
- •
Evidence of nutrient partitioning among coexisting taxa was found in carbon data.
- •
Echinoids incorporate foods with higher δ15N values than that of POM and sediment.
- •
Surface phytodetritus was incorporated into the gonads of the seasonal breeder.
- •
It was incorporated in somatic tissues of continuous breeders, or not at all.
