Description:
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 expenditure. Our model provides a framework that reconciles these two approaches and highlights the fundamental principles that determine rates of food assimilation and rates of energy allocation to maintenance, biosynthesis, activity, and storage. The model predicts that growth and assimilation rates for all animals should cluster closely around two universal curves. Data for mammals and birds of diverse body sizes and taxa support these predictions.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2891030/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉 〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2891030/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hou, Chen -- Zuo, Wenyun -- Moses, Melanie E -- Woodruff, William H -- Brown, James H -- West, Geoffrey B -- DK36263/DK/NIDDK NIH HHS/ -- P20 RR-018754/RR/NCRR NIH HHS/ -- P20 RR018754/RR/NCRR NIH HHS/ -- P20 RR018754-06A1/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 2008 Oct 31;322(5902):736-9. doi: 10.1126/science.1162302.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Santa Fe Institute, 1399 Hyde Park Road, Santa Fe, NM 87501, USA. houc@santafe.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18974352" target="_blank"〉PubMed〈/a〉
