Developing nondestructive species‐specific tree allometry with terrestrial laser scanning

open access: yesMethods in Ecology and Evolution, 2023
Allometric equations predict organism attributes from simple measurements and underlie many global‐scale estimates, from plant productivity to ecosystem carbon stocks. In forests, destructive harvesting of trees in common groups (e.g.

A gentle introduction to scaling relations in biological systems

open access: yesRevista Brasileira de Ensino de Física, 2022
In this paper it is presented a gentle review of empirical and theoretical advances in understanding the role of size in biological organisms. More specifically, it deals with how the energy demand, expressed by the metabolic rate, changes according to ...

Effect of temperature and glia in brain size enlargement and origin of allometric body-brain size scaling in vertebrates [PDF]

open access: yes, 2014
Background: Brain signaling requires energy. The cost of maintaining and supporting energetically demanding neurons is the key constraint on brain size.

Biological scaling in green algae: the role of cell size and geometry

open access: yesScientific Reports, 2021
The Metabolic Scaling Theory (MST), hypothesizes limitations of resource-transport networks in organisms and predicts their optimization into fractal-like structures.

Biomass allometric models for Larix rupprechtii based on Kosak’s taper curve equations and nonlinear seemingly unrelated regression

open access: yesFrontiers in Plant Science, 2023
The diameter at breast height (DBH) is the most important independent variable in biomass allometry models based on metabolic scaling theory (MST) or geometric theory. However, the fixed position DBH can be misleading in its use of universal scaling laws

Variable metabolic scaling breaks the law: from ‘Newtonian’ to ‘Darwinian’ approaches

open access: yesProceedings of the Royal Society B, 2022
Life's size and tempo are intimately linked. The rate of metabolism varies with body mass in remarkably regular ways that can often be described by a simple power function, where the scaling exponent (b, slope in a log-linear plot) is typically less than

Scaling laws in bacterial genomes: A side-effect of selection of mutational robustness? [PDF]

open access: yes, 2010
In the past few years, numerous research projects have focused on identifying and understanding scaling properties in the gene content of prokaryote genomes and the intricacy of their regulation networks.

Allometric convergence in savanna trees and implications for the use of plant scaling models in variable ecosystems. [PDF]

open access: yesPLoS ONE, 2013
Theoretical models of allometric scaling provide frameworks for understanding and predicting how and why the morphology and function of organisms vary with scale.

Data from: Ontogenetic and interspecific metabolic scaling in insects [PDF]

open access: yes, 2014
Design constraints imposed by increasing size cause metabolic rate in animals to increase more slowly than mass. This ubiquitous biological phenomenon is referred to as metabolic scaling.
