Starvation effects on nitrogen and carbon stable isotopes of animals: an insight from meta-analysis of fasting experiments.

ABSTRACT: Nitrogen and carbon stable isotopic compositions (δ¹⁵N and δ¹³C) of consumers have been used for physiological and food web studies. Previous studies have shown δ¹⁵N and δ¹³C values are affected by several biological and environmental factors during starvation, but the generality of the effect of starvation on δ¹⁵N and δ¹³C values has not yet been tested. Here, we performed a meta-analysis to evaluate the effects of starvation on δ¹⁵N and δ¹³C values of consumers, and the underlying factors that may explain the observed variation. The δ¹⁵N and δ¹³C values were calculated as the differences between the final δ¹⁵
