Comment on "Energy uptake and allocation during ontogeny".

چکیده
We demonstrate that the model of energy allocation during ontogeny of Hou et al. (Reports, 31 October 2008, p. 736) fails to account for the observed elevation of metabolic rate in growing organisms compared with similarly sized adults of different species. The basic model assumptions of the three-quarter power scaling for resting metabolism and constancy of the mass-specific maintenance metabolism need to be reassessed.

Energy uptake and allocation during ontogeny.
All organisms face the problem of how to fuel ontogenetic growth. We present a model, empirically grounded in data from birds and mammals, that correctly predicts how growing animals allocate food energy between synthesis of new biomass and maintenance of existing biomass. Previous energy budget models have typically had their bases in rates of either food consumption or metabolic energy expend...
متن کاملOntogenetic changes in lipids, fatty acid, and body composition during larval stages of Caspian Kutum (Rutilus frisii kutum)
Body composition and fatty acid profile of the body tissue of Caspian kutum (Rutilus frisii kutum) fish larvae were determined from fertilized egg to 50 days post hatching (dph). Feeding with rotifer started from day 3 to day 7 thereafter they were fed with dry food until the end of the experiment. The changes observed in lipid content and the decrease in lipid levels during larval ontogeny ref...

متن کاملLong-term Care Financing: Inserting Politics and Resource Allocation in the Debate; Comment on “Financing Long-term Care: Lessons From Japan”
The ageing of the countries’ populations, and in particular the growing number of the very old, is increasing the need for long-term care (LTC). Not surprisingly, therefore, the financing of LTC systems has become a crucial topic across the Organisation for Economic Co-operation and Development (OECD). In the last three decades, various financing policies have been carr...
متن کاملThe effect of food type on phenotypic plasticity of sword tail, Xiphophurus helleri, during early ontogeny
Phenotypic plasticity is an important mechanism of phenotypic adaptation in response to environmental conditions. This study was conducted to investigate the effect of food type on the body shape of swordtail, Xiphoohurus helleri, during early development using geometric morphometric method. For this purpose, two treatments including feed by Artemia naupli and commercial Biomar diet were used i...
