Functional and comparative digestive system anatomy of Arctic ungulates
Dietary niche, feeding type classification and seasonal strategies of Rangifer tarandus and Ovibos moschatus discussed in relation to the anatomy of their digestive system. Classification criteria for the flexible feeding type system, originally established in bovids and later adapted to cervids, ar...
