Allometric scaling in animals and plants

Journal of Mathematical Biology, 2001
In this paper we give a derivation for the allometric scaling relation between the metabolic rate and the mass of animals and plants. We show that the characteristic scaling exponent of 3/4 occurring in this relation is a result of the distribution of sources and sinks within the living organism.

EMERGENCE OF ALLOMETRIC SCALING IN GENEALOGICAL TREES [PDF]

Advances in Complex Systems, 2004
We investigate the emergence of power-law scalings in genealogical trees. Especially, we study the topological properties of genealogical trees both in the neutral evolution and the selective evolution. In all instances, we observe that the topologies of these trees are well described by a power-law scaling [Formula: see text], where Akis the number of

Multi-scaling allometric analysis for urban and regional development [PDF]

Physica A: Statistical Mechanics and Its Applications, 2017
The concept of allometric growth is based on scaling relations, and it has been applied to urban and regional analysis for a long time. However, most allometric analyses were devoted to the single proportional relation between two elements of a ...

Allometric scaling of clearance in dogs

Journal of Veterinary Pharmacology and Therapeutics, 2009
Most drugs indicated for use in dogs are labeled for administration on a mg/kg basis. Such dosing recommendations are grounded on an assumption that total body clearance (Cl) scales in a manner directly proportional to body weight (i.e. that it scales with an allometric exponent of 1). Despite the critical nature of this assumption (the range of normal

Allometric Scaling in Biology

Science, 1998
T he design of living beings is not only a matter of molecular biology but also of geometry and physics. This was once more demonstrated with a biophysical model by G. B. West et al . ([1][1]) that had been fine-tuned to predict the famous scaling law of metabolism ([2][2]), namely a 3/4 ...

Allometric Scaling for Character Design

Computer Graphics Forum, 2011
AbstractGeometric scaling transformations do not respect the biological processes which govern the size and shape of living creatures. In this paper, we describe an approach to scaling which can be related to biological function. We use known biological laws of allometry which are expressed as power laws to control the mesh deformation in the frequency

Testing the allometric scaling laws

Journal of Theoretical Biology, 2004
Allometric scaling laws have received increasing attention due to the recent theoretical advancements. However, existing evidence suggests that the scaling relationships may vary a lot without much consistency, which poses a challenge to the applicability of general theories. In this report, I demonstrate that much of the discrepancy may be an artefact

Interspecies Allometric Scaling

2010
Lack of approved pharmaceutical agents and very limited pharmacokinetic data in the scientific literature for exotic, wildlife, and zoo species are a major issue for veterinarians treating these species. There are fewer than 15 compounds approved in the United States for zoo and wildlife species compared to nearly 300 drugs licensed for cattle.
