  • Allometry is the study of the relationship between size and shape,, first outlined by Otto Snell in 1892 and Julian Huxley in 1932. Allometry is a well-known study, particularly in statistical shape analysis for its theoretical developments, as well as in biology for practical applications to the differential growth rates of the parts of a living organism's body. One application is in the study of various insect species, where a small change in overall body size can lead to an enormous and disproportionate increase in the dimensions of appendages such as legs, antennae, or horns. Allometry studies shape differences in terms of ratios of the objects' dimensions. Two objects of different size but common shape will have their dimensions in the same ratio. Take, for example, a biological object that grows as it matures. Its size changes with age but the shapes are similar. Studies of ontogenetic allometry often use lizards or snakes as model organisms because they lack parental care after birth or hatching and because they exhibit a large range of body size between the juvenile and adult stage. Lizards often exhibit allometric changes during their ontogeny.
  • Bei der Allometrie (von griechisch allos „anders“; metrie „messen“) geht es um das Messen und Vergleichen von Beziehungen zwischen der Körpergröße und deren Verhältnis zu verschiedensten biologischen Größen. So kann die Leistung eines Organismus beispielsweise nicht kurzerhand von klein auf groß übertragen werden. Auch die Größenverhältnisse innerhalb einer Art können nicht 1:1 umgesetzt werden. Würde zum Beispiel der Kopf vom Säugling zum Erwachsenen proportional zur Gesamtlänge des Körpers zunehmen, müsste unser Kopf circa 45 cm hoch sein.
  • Stephen Jay Gould (1966) distingue cuatro conceptos de alometría: el ontogenético, el filogenético, el intraespecífico y el interespecífico. La alometría ontogenética se refiere al crecimiento relativo en los individuos; La alometría filogenética se refiere a las tasas de crecimiento diferencial en los linajes; La alometría intraespecífica se refiere a los individuos adultos de una especie o una población local; La alometría interespecífica se refiere al mismo fenómeno entre especies relacionadas. Las relaciones alométricas son de la forma: <math>Y= a \cdot x^b \longmapsto log(Y) = log(a) + b \cdot log(x)</math> En donde b es la pendiente de la recta . Relación entre metabolismo estándar y masa corporal: <math> R = alfa\cdot W^{0,75} </math> Es decir, la tasa metabólica R aumenta con la masa corporal W.
  • Allometrisk vekst (allo = ulike steder, metro = distanse, avstand), er et begrep som blir brukt innen biologi. Ulike deler av organismens anatomi vokser og utvikler seg med ulik hastighet gjennom livsløpet, men opphører som regel i større eller mindre grad når kjønnsmodning og/eller vekst er fullendt. Man skiller mellom to ulike former for allometrisk vekst, som på engelsk kalles for postdisplacement og predisplacement. Førstnevnte går inn under pedomorfose og innebærer at en eller flere strukturer blir hengende etter i utviklingen i forhold til resten av organismen. Sistnevnte går inn under peramorfose og innebærer at en eller flere strukturer blir gjenstand for sterkere og tidligere utvikling enn resten av organismen.
