Metabolic scaling in small life forms [PDF]
bioRxiv, 2023 Metabolic scaling is one of the most important patterns in biology. Theory explaining the 3/4-power size-scaling of biological metabolic rate does not predict the non-linear scaling observed for smaller life forms. Here we present a new model for cells <

The Evolution of Offspring Size: A Metabolic Scaling Perspective [PDF]
Integrative and Comparative Biology, 2022 Size at the start of life reflects the initial per offspring parental investment—including both the embryo and the nutrients supplied to it. Initial offspring size can vary substantially, both within and among species.

Plant allometry derived from Metabolic Scaling Theory and segregated by tissue functionality
bioRxiv, 2023 Abstract Plant allometry is key for determining the role of forests in global carbon cycles, through the calculation of tree biomass using proxy measurements such as tree diameters or heights. Metabolic Scaling Theory (MST) considers the general principles that underpin allometry, but MST scaling relationships have been challenged on ...

Improving quantitative structure models of trees inspired by pipe and metabolic scaling theory
bioRxiv, 2022 Abstract Purpose We invent in this manuscript new tree parameters which can be derived from a single QSM. QSMs are topological ordered cylinder models of trees which describe the branching structure up to the tips.

Benthic biomass size spectra in shelf and deep-sea sediments [PDF]
Biogeosciences, 2014 The biomass distributions of marine benthic metazoans (meio- to macro-fauna, 1 μg–32 mg wet weight) across three contrasting sites were investigated to test the hypothesis that allometry can consistently explain observed trends in biomass spectra ...

Metabolic theory of ecology successfully predicts distinct scaling of ectoparasite load on hosts [PDF]
Proceedings of the Royal Society B: Biological Sciences, 2019 The impacts of parasites on hosts and the role that parasites play in ecosystems must be underlain by the load of parasites in individual hosts. To help explain and predict parasite load across a broad range of species, quantitative theory has been developed based on fundamental relationships between organism size, temperature and metabolic rate. Here,

Toward a metabolic theory of catchments: Scaling of water and carbon fluxes with size
Proceedings of the National Academy of SciencesAllometric scaling relations are widely used to link biological processes to body size in nature. Several studies have shown that such scaling laws hold also for natural ecosystems, including individual trees and forests, riverine metabolism, and river network organization.

Thermodynamic-based ecological scaling theory in urban metabolic framework: a review
Frontiers of Environmental Science & EngineeringAbstract Prior research has consistently demonstrated that urban economic and social systems adhere to the empirical scaling law. Furthermore, a plethora of evidence, including the scale-free networks of energy metabolism, the allometric growth patterns of species and populations, and the scaling law relationship between exergy and ...

Why does offspring size affect performance? Integrating metabolic scaling with life-history theory [PDF]
Proceedings of the Royal Society B: Biological Sciences, 2015 Within species, larger offspring typically outperform smaller offspring. While the relationship between offspring size and performance is ubiquitous, the cause of this relationship remains elusive. By linking metabolic and life-history theory, we provide a general explanation for why larger offspring perform better than smaller offspring.
