Implications of allometry.

Evolution of morphological allometry.

Morphological allometry refers to patterns of covariance between body parts resulting from variation in body size. Whether measured during growth (ontogenetic allometry), among individuals at similar developmental stage (static allometry), or among populations or species (evolutionary allometry), allometric relationships are often tight and relatively invariant. Consequently, it has been sugges...

Multivariate Allometry

The subject of allometry is variation in morphometric variables or other features of organisms associated with variation in size. Such variation can be produced by several biological phenomena, and three different levels of allometry are therefore distinguished: static allometry reflects individual variation within a population and age class, ontogenetic allometry is due to growth processes, an...

Statistical origin of allometry

The allometry relationship (AR) between two properties of a living network X and Y is X = aY b where one or both of the variables is a measure of size and the allometry coefficient a and exponent b are fit to data. Many investigators have focused on determining the proper value of b entailed by an appropriate biological model, whereas others have argued that the allometry coefficient plays the ...
