Published: 15 July 2008
... breath of fasting birds and mammals was depleted in 13 C by–3.2±2.0‰ in relation toδ 13 C diet . δ 13 C breath of satiated animals differed by –0.6±2.3‰ fromδ 13 C diet when endogenous substrates were not in isotopic equilibrium with exogenous substrates and by +0.5±1.8‰(N =6 species) after endogenous...
