Digestive system: The diminished food requirements during winter are reflected by the extensive manifestations of inactivity in the digestive tract during hibernation. In histological and biochemical studies, an involution of salivary, intestinal and gastric glands can be observed (Henriksen 1972, Mayer W.

Further, there is a weight loss of the intestine and of the pan- creas as well as a diminished protein content (Senturia and Johansson 1972). Arousal leads to a reactivation of the digestive system. Summary: The instinctive habits of nutrition show quantitative and qualitative adaptations to the prehibernatory and hibernatory requirements of the organism, including the hibernation inactivity of the digestive Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Bonn, Zoologisches Forschungsinstitut und Museum Alexander Koenig
