HIGHLIGHTS
- who: Rafael from the NUPELIA, Universidade Estadual Maringá, AvColombo, CEP, Maringá, Brazil have published the research: CARBON SOURCES AND TROPHIC POSITION OF THE MAIN SPECIES OF FISHES OF BAÍA RIVER, PARANÁ RIVER FLOODPLAIN, BRAZIL, in the Journal: (JOURNAL)
- how: For the trophic position estimate through δ15N isotopic values (PTδ15N) and dietary (PTMd) the authors used the expression proposed by Vander-Zanden et_al PTδ15N=((δ15Nfish - δ15Nsource)/3.4) + 1 where δ15Nfish is the δ15N mean value of each species δ15Nsource is the δ15N mean value of allochthonous and autochthonous sources.
