where λ is trophic position of a species of fish.
The seals were in the highest trophic position with an average value of 5.1.
Second, the error in the estimated trophic position can be minimized.
Stable isotope analysis has been used to evaluate dietary sources and the trophic position of fish.
Despite this, accompanying changes in trophic position are superficial because both stages are carnivorous generalists.
To assess the trophic position of organisms, stable isotope analyses were used (13C and 15N).
Differences in the trophic position of higher consumers (fish) were also recorded between FPZs.
First, the isotopic composition of the autotroph ([TP] = 1) is not required to estimate the trophic position.
We derived community indices from species traits of habitat specialisation, trophic position, relative brain size and body mass.
Further, multiple taxa at comparable trophic position showed similar patterns in relation to watershed-scale land use.
where TP represents the trophic position, and TP = 1, 2, and 3 correspond to the trophic positions of plants, i.e., autotrophs, herbivores, and primary carnivores, respectively.
