203 The key specific feature of phytophagous animals is feeding on celluloseecontaining food with a low proo tein content. A fulllscale use of this food as a source of energy and nutrients is possible due to microbial endoo symbionts. They not only destroy polysaccharides that are hard to digest, but also enrich food mass with bacc terial protein as a result of nitrogen fixation. In anii mals with postgastric fermentation (for instance, lagoo morphs and many rodents), the accumulated biomass of… Expand
Microbial Nitrogen Fixation in the Intestine of Tipulidae Tipula maxima Larvae
Nitrogen fixers actively developing in the intestines of larvae stimulate a sharp increase in nitrogenase activity in the soil: after 3 months of incubation, the activity increases eightfold; it can contribute to the accumulation of nitrogen in the habitats of the larvae. Expand
Urease activity in the gastrointestinal tract of the European hare (Lepus europaeus)
The intensity of urea recycling in the wild herbivorous European hare has been investigated; high urease activity was detected in the large intestine, higher than the previously detected activity in other mammals with postgastric fermentation: pigs, rats, and rabbits. Expand
Urea Recycling in Muroid Rodents
The results of urease activity studies in the digestive tract of muroid rodents Microtus socialis and Meriones meridianus are considered and the pronounced postgastric character ofUrealytic fermentation was shown. Expand


Coprophagy in leporids and other mammalian herbivores
Leporids are the largest of the reingesting species except for the semi-aquatic Coypu, and reingestion by leporids is certainly the most sophisticated, hence its study is important to understanding of their ecology and biology. Expand
Nitrogen fixation as a possible physiological basis of coprophagy in pikas (Ochotona, Lagomorpha, Mammalia)
Two families of the order Lagomorpha, Ochoto� nidae, and Leporidae, are characterized by a peculiar dietary adaptation, i.e., obligate autocoprophagy. The animal produces excrement of two types:Expand
Coprophagy in the Japanese hare (Lepus brachyurus): reingestion of all the hard and soft faeces during the daytime stay in the form
The daily rhythms of formation and reingestion of hard and soft faeces were studied in Lepus brachyurus, showing that the Japanese hare also reingests a substantial amount of hard faece, and evidence in literature indicates that other Leporidae also practise reingestepping. Expand
Coprophagy in the Rabbit: Origin of “Night” Fæces
Investigation of faeces of the rabbit obtained when coprophagy was prevented by collaring has shown even more striking differences in respect of other constituents, notably in protein and fibre. Expand

I am writing with a simple plea to balance the voluminous articles about treatment in your journal with a modicum of information about nature and caring effects to rekindle the perception of physicians as healers, not only treaters, who relish the gifts of nature, and foster the humanistic aspect of medicine that has thrived for millennia.
