Pooled Energy Budgets: Resituating Human Energy Allocation Trade-offs

Across taxa, many life-history traits vary as a function of differences in body size. Among primates, including humans, allometric relationships explain many trends in metabolic, growth, reproductive, and mortality rates. But humans also deviate from nonhuman primates with respect to other developmental, reproductive, and parenting characteristics. Broad relationships between life-history trait...

Comments on Dynamic Energy and Mass budgets in Biological Systems

Energy budgets in Charney-Hasegawa-Mima and surface quasigeostrophic turbulence.

We study energy transfer in unbounded Charney-Hasegawa-Mima and surface quasigeostrophic turbulence. The possible inverse-cascading quantities in these systems are, respectively, I identical with integral ( infinity )(0)k(-2)E(k) dk and J identical with integral ( infinity )(0)k(-1)E(k) dk, where E(k) is the kinetic energy spectrum. The supposed direct-cascading quantities for both surface quas...

Energy cost of wheel running in house mice: implications for coadaptation of locomotion and energy budgets.

Laboratory house mice (Mus domesticus) that had experienced 10 generations of artificial selection for high levels of voluntary wheel running ran about 70% more total revolutions per day than did mice from random-bred control lines. The difference resulted primarily from increased average velocities rather than from increased time spent running. Within all eight lines (four selected, four contr...

Modelling nematode life cycles using dynamic energy budgets

1. To understand the life cycle of an organism, it is important to understand the underlying physiological mechanisms of their life histories. We here use the theory of dynamic energy budgets (DEB) to investigate the close relationships between growth, reproduction and respiration in nematodes. 2. Using a set of simplified equations based on DEB theory, we are able to accurately describe life-c...
