d13C and d15N reveal significant differences in the coastal foodwebs of the seas surrounding Trinidad and Tobago

Mallela, Jennie-Ann; Harrod, Chris


This study assessed nearshore, marine ecosystem function around Trinidad and Tobago (TT). The coastline of TT is highly complex, bordered by the Atlantic Ocean, the Caribbean Sea, the Gulf of Paria and the Columbus Channel, and subject to local terrestrial runoff and regional riverine inputs (e.g. the Orinoco and Amazon rivers). Coastal organisms can assimilate energy from allochthonous and autochthonous sources. We assessed whether stable isotopes δ13C and δ15N could be used to provide a rapid...[Show more]
