Why are metabolic scaling exponents so controversial? Quantifying variance and testing hypotheses [PDF]

open access: yesEcology Letters, 2010
The metabolic theory of ecology links physiology with ecology, and successfully predicts many allometric scaling relationships. In recent years, proponents and critics of metabolic theory have debated vigorously about the scaling of metabolic rate.

Metabolic scaling is the product of life-history optimization

Science, 2022
Organisms use energy to grow and reproduce, so the processes of energy metabolism and biological production should be tightly bound. On the basis of this tenet, we developed and tested a new theory that predicts the relationships among three fundamental ...

A metabolic scaling theory-driven remote sensing approach to map spatiotemporal dynamics of litterfall in a tropical montane cloud forest

International Journal of Applied Earth Observation and Geoinformation, 2019
Litter production, or litterfall, is a predominant part of the carbon and nutrient cycles of forest ecosystems. As a major and relatively invariable aspect of primary production, litterfall could be a predictor of total plant production.

Metabolic reconstruction, constraint-based analysis and game theory to probe genome-scale metabolic networks

Current Opinion in Biotechnology, 2010
With the advent of modern omics technologies, it has become feasible to reconstruct (quasi-) whole-cell metabolic networks and characterize them in more and more detail. Computer simulations of the dynamic behavior of such networks are difficult due to a lack of kinetic data and to computational limitations.

Exploring the role of temperature in the ocean through metabolic scaling [PDF]

open access: yesEcology, 2015
Temperature imposes a constraint on the rates and outcomes of ecological processes that determine community- and ecosystem-level patterns. The application of metabolic scaling theory has advanced our understanding of the influence of temperature on ...

Metabolic scaling is demand driven

Journal of Zoology
Metabolic scaling is a major regularity in nature. Existing theory explains this scaling in terms of the optimal geometry of resource supply networks.

DOES METABOLIC THEORY APPLY TO COMMUNITY ECOLOGY? IT'S A MATTER OF SCALE

Ecology, 2004
al. (2004), there were moments of insight, of enthusiastic consensus, and of strongly divergent opinion. We agreed that the empirical relations and scaling theory of Brown et al. (2004) hold great appeal because of their power to abstract and simplify some of the complexity of nature.

Size matters in metabolic scaling: Critical role of the thermodynamic efficiency of ATP synthesis and its dependence on mitochondrial H+ leak across mammalian species

Biosyst.
In this last article of the trilogy, the unified biothermokinetic theory of ATP synthesis developed in the previous two papers is applied to a major problem in comparative physiology, biochemistry, and ecology-that of metabolic scaling as a function of ...

Ventilation Frequency Reveals the Roles of Exchange Surface Areas in Metabolic Scaling

Physiological and Biochemical Zoology, 2020
The surface area (SA) theory proposes that resting metabolic rate (RMR) scales with body mass, which parallels the exchange SA of organisms, and that a species with a larger scaling exponent of exchange SA has a larger scaling exponent of RMR.

Parametrized maximum entropy models predict variability of metabolic scaling across tree communities and populations.

Ecology, 2020
The maximum entropy theory of ecology (METE) applies the concept of "entropy" from information theory to predict macroecological patterns. The energetic predictions of the METE rely on predetermined metabolic scaling from external theories, and this ...
