Effect of temperature, ration, body size and age on sulphur isotope fractionation in fish.

Sulphur isotope analysis (delta(34)S) is increasingly identified as a valuable tool for source differentiation and the determination of trophic level in food webs, but there are still many uncertainties associated with the interpretation of delta(34)S data. To investigate the effects of temperature, ration, body size and age on sulphur trophic fractionation… CONTINUE READING
