The shivering response during cross‐circulation in the common eider duck ( Somateria mollissima)
The possible role of humoral factors in the control of shivering in the common eider duck ( Somateria mollissima ) was investigated using a cross‐circulation technique. Pairs of animals were coupled so that the arterial system of one animal was connected to the venous system of the other. The rate o...
