Microclimate of the nest and egg water loss of the eider Somateria mollissima and other waterfowl in Spitsbergen
Temperature gradients in the nest and within the egg. nest humidity as well as eggshell conductance and rate of egg water loss of the Eider Somareria mollissrma and other uaterfowl were studied at Ny-Alesund. Spitsbergen (78%" latitude). These studies suggest a specific interrelationship betwee...
