Short summary
The trophic preference (i.e., food resources and trophic levels) of different copepod groups was assessed along a salinity gradient in the temperate estuarine Gwangyang Bay of Korea, based on a seasonal investigation of taxonomic results in 2015 and stable isotope analysis incorporating multiple linear regression models. Our results depict a simple energy flow of the planktonic food web of Gwangyang Bay.
