Appetite and the regulation of body composition.
Stability of body composition requires that energy intake equals energy expenditure when integrated over prolonged periods. As recent human studies have failed to demonstrate active changes in energy expenditure with changes in body composition, it is likely that energy intake is continually adjusted to preserve a constant total adipose tissue mass. If adipose tissue mass is regulated directly,...
متن کاملAdaptation of the microflora in the rumen and caecum of the high arctic Svalbard reindeer
The Svalbard reindeer relies on a highly active rumen microbial population of bacteria, fungi and protozoa for the utilization of cellulose and hemicellulose, the major components of growing plants (Rogers and Perkins, 1968). O n Svalbard the availability and quality of food changes during the year, ranging from fresh young forage in summer (July September), to a highly concentrated diet, inclu...

متن کاملMicrosatellite DNA evidence for genetic drift and philopatry in Svalbard reindeer.
Mainland populations of Arctic reindeer and caribou Rangifer tarandus often undergo extensive movements, whereas populations on islands tend to be isolated and sedentary. To characterize the genetic consequences of this difference, levels of genetic diversity and subdivision of Svalbard reindeer (R. t. platyrhynchus) from two adjacent areas on Nordenskjiöldland, Spitsbergen were estimated using...
متن کاملCorrection: Metagenomics of the Svalbard Reindeer Rumen Microbiome Reveals Abundance of Polysaccharide Utilization Loci
Lignocellulosic biomass remains a largely untapped source of renewable energy predominantly due to its recalcitrance and an incomplete understanding of how this is overcome in nature. We present here a compositional and comparative analysis of metagenomic data pertaining to a natural biomass-converting ecosystem adapted to austere arctic nutritional conditions, namely the rumen microbiome of Sv...
