  journal={Biology Bulletin},
The nitrogen-fixing activity, nitrogen (N) and carbon (C) contents, and the number of microorganisms in the forestomach, cecum, and colon were detected in two gerbil species, granivorous Meriones meridianus and M. tamariscinus, which consume a large amount of green parts of the plants. M. meridianus had higher levels of nitrogen-fixation activity in all investigated parts of the gastro-intestinal tract compared with M. tamariscinus. The highest levels were detected in the colon of M. meridianus… Expand
Nitrogenase diversity and activity in the gastrointestinal tract of the wood-eating catfish Panaque nigrolineatus
The intake of a cellulose rich diet and the presence of a suitable environment for nitrogen fixation suggest that the GI tract microbial community may allow a unique trophic niche for P. nigrolineatus among fish. Expand
Functional features of microbial communities in the digestive tract of field voles (Microtus rossiaemeridionalis and Clethrionomys glareolus)
The nitrogen-fixating activity in the cecum was found to be the highest in the voles compared with the mammals studied earlier and the seasonal dynamics of both nitrogenase and cellobiohydrolase activities was registered in the southern vole. Expand
Algal associates and the evidence of cyanobacterial nitrogen fixation in the velamen roots of epiphytic orchids
Preliminary level empirical evidence is sufficient to consider the velamen roots of epiphytic orchids as an ecologically complex aerial ‘organ ecosystem’ with microbial partnerships for nutritional support, especially nitrogen availability in epipHYticOrchids. Expand
Desert Gerbils Affect Bacterial Composition of Soil
It is concluded that gerbils play an important role as ecosystem engineers within their burrow environment and affect the microbial complex of the nitrogen-fixing organisms in soils. Expand
Functional Diversity of Morphologically Similar Digestive Organs in Muroidea Species
Abstract We examine possible ways of functional adjustment of morphologically similar alimentary tracts in rodents with different dietary specializations. We study the structure of stomach and gutExpand


The Enzymatic Activity of the Gastrointestinal Tract Microflora of the Greater Mole Rat (Spalax microphtalmus, Spalacidae, Rodentia)
The purpose of this work was to obtain more detailed data on relative development of different segments of the intestine of mole rats (as a key index of using dietary fiber as a nutrient) and to determine the level of activity of symbiotic enzymes responsible for the digestion of plant glucans, topographically related to dietary fibers, and molecular nitrogen fixing (nitrogenases).

Effect of Deficiency of Dietary Nitrogen on Cellulose Digestibility and Nitrogen-Fixing Flora Activity in Sibling Vole Microtus rossiaemeridionalis
The effect of feed composition on nitrogen-fixing activity of the symbionts living in the digestive tract of sibling vole Microtus rossiaemeridionalis was experimentally studied and the colon was the major locus of nitrogen fixation. Expand
Assimilation of biological nitrogen by European beaver
A high nitrogen-fixing activity in the large intestine correlated with an increase in nitrogen content in the chyme upon its transfer over the gastrointestinal tract. Expand
Some specific features of nitrogen fixation in the digestive tract of the European beaver (Castor fiber)
The European beaver is an important component of aquatic and bog ecosystems; in the European part of Russia, its population density reaches nine animals per kilometer of the coastline. Expand
Specific Features of Nitrogen Transformation in the Soddy-Podsolic Soil in the Colonies of the Common Vole Microtus arvalis
In the common vole colonies, the level of nitrogen fixation was reliably lower and that of denitrification higher, than in the control soil outside these colonies. Expand
