Allometric relationships can be determined during development (ontogenetic allometry) or in mature individuals throughout the process of evolution of a species (phylogenetic allometry) (Pilbeam & Gould, 1974).
The length-weight relationship was determined by adjusting the potential equation W = aLtb by logarithmic transformation in ln W = ln a + b ln Lt order to smooth the variance (Zar, 2009) where W is the total weight in g, TL is the total length in cm, a is the intercept, and b is the allometric coefficient.
The length/weight relationship (LWR) was obtained for each sex by non-linear regression analysis, in which weight and length data were directly adjusted by the function: Total weight = a*Standard lengthb, being: a = constant and b = angular coefficient of growth; with b = 3 isometric, b < 3 negative allometric and b > 3 positive allometric (Jones et al., 1999).
In this method, biomass can be inferred through plot-level measurement of structural variables, using allometric equations specific to each species or group of species, considering the local situation (climate, ecosystem, and species) from measurements of diameter and height of the trees (Table 1) (Pearson et al., 2005).
(2016), have reported that the "b" values obtained in their study were low with negative allometric growth.
The value of the regression coefficient [beta] was statistically evaluated by using the Student's t-test (Zar 2010) to determine the type of growth exhibited by the species: if [beta] [not equal to] 3, the growth is allometric; if [beta] = 3, the growth is isometric (Ricker 1975), thus posing the hypotheses Ho: [beta] = 3 and Ha: [beta] [not equal to] 3
The second method, allometric scaling, is based on a principle proposed by Rubner (36), which is generally referred to as either geometric or biological similarity (43), and has recently been applied in health sciences or human movement sciences (31).
To design allometric equations for Iranian boys, regression analysis and logarithmic conversion of equation y=a[x.sup.b] to Log (y) = Log (a) + bLog (x) were used.
