allometric growth

allometric growth

the increase in size of different organs or parts of an organism at various rates. Also called heterauxesis. Compare isometric growth. See also allometry.

allometric growth

  1. unequal growth rate in different portions of the body of an organism that gives rise to the final shape.
  2. growth of a particular structure at a constantly greater rate than the whole.

Because settlement and sexual maturity are distinct biological events in the life history of this fish, the timing of these events will be clearly demonstrated in allometric growth.
turnerae, marginal spines show negatively allometric growth relative to body diameter through life, meaning that the spines are relatively longest in the smallest animals.
incanum was chosen partly for its accessibility, and partly because it is a normal that clearly displays the characteristic triphasic allometric growth pattern.
This result conformed to the findings of Adedokun who reported positive allometric growth in Hepsetus odoe in Ogbomoso reservoir [13].
verrucosa showed consistent negative allometric growth, whereas the TW/SL (b = 3.
b], converted to the linear form by means of natural logarithm transformation (Ln(y) = Ln(a) + b Ln(x), where y = dependent variables (CL, CPL, CPH, GL, AW), x = independent variable (CW), a = intercept on y axis, and b = allometric growth coefficient.
In some crustacean species, morphometric relationships used to detect the size at sexual maturity by variations in the allometric growth, also have been adjusted by linear models (Streissl & Hodl, 2002; Gerhart & Bert, 2008).
By truncating the application of our growth model at the approximate minimum size of fish caught by the Hawaii-based longline fishery (60-cm EFL), we eliminate the markedly allometric growth effects that half-year-old and younger fish have on the ascending limb of the VBGF curve.
Vermeij (1993) examined allometry as a morphological descriptor of shape in gastropods, and noted that high allometric growth rates in gastropods have been correlated with low overall growth rates, Green (2001) demonstrated higher rates of allometric growth in Black Sea populations of R.
Directions of allometric growth trajectories reflect the relative magnitudes of specific growth rates of the traits studied (Shea 1985; Blackstone 1987a).
In the present study the b value was lower in the LSS infected shrimps showed the negative allometric growth than the normal shrimps where isometric growth, its strongly revealed that the growth of the shrimps affected by the LSS infection in the culture pond.
