Model explanation of the seasonal variation of δ18O in cow (Bos taurus) hair under temperate conditions

Oxygen isotopes (δ 18 O) in animal and human tissues are expected to be good recorders of geographical origin and migration histories. However, seasonal variation of δ 18 O may diminish the origin information in the tissues. Here the seasonality of δ 18 O in tail hair was investigated in a domestic...

Description
Summary:Oxygen isotopes (δ 18 O) in animal and human tissues are expected to be good recorders of geographical origin and migration histories. However, seasonal variation of δ 18 O may diminish the origin information in the tissues. Here the seasonality of δ 18 O in tail hair was investigated in a domestic suckler cow ( Bos taurus ) that underwent different ambient conditions, physiological states, keeping and feeding during five years. A detailed mechanistic model was built to explain this variation. The measured δ 18 O in hair significantly related (p
