Allometry (Ancient Greek ἄλλος állos "other", μέτρον métron "measurement") is the study of the relationship of body size to shape, [1] anatomy, physiology and behaviour, [2] first outlined by Otto Snell in 1892, [3] by D'Arcy Thompson in 1917 in On Growth and Form [4] and by Julian Huxley in 1932.
Allometric engineering has been used to test David Lack's hypothesis in the lizard Sceloporus occidentalis. [1] In this study, two populations were "engineered" to fit the morphology of the other by manipulating egg yolk quantity, removing effect of size difference between groups.
Tree allometry narrows the definition to applications involving measurements of the growth or size of trees. Allometric relationships often are used to estimate difficult tree measurements, such as volume, from an easily measured attribute such as diameter at breast height (DBH). The use of allometry is widespread in forestry and forest ecology.
Cranial evolutionary allometry (CREA) is a scientific theory regarding trends in the shape of mammalian skulls during the course of evolution in accordance with body size (i.e., allometry). Specifically, the theory posits that there is a propensity among closely related mammalian groups for the skulls of the smaller species to be short and ...

Language Teaching is an academic journal in language education that publishes approximately 30 research articles a year in the field of second-language teaching and learning. Published by Cambridge University Press , papers focus on specific topics, languages and countries.
Option One: Extending practice and English language teaching specialism. This focuses on needs analysis, syllabus design, course planning and assessment in the context of a selected specialism (e.g. English for academic purposes, teaching exam classes, young learners, one-to-one teaching). Option Two: English language teaching management.
Of principal concern are considerations relating to: (1) the nature of language teaching, (2) the modular approach to materials development, (3) evaluating and adapting language materials, (4) writing adaptable materials, (5) learners' synopses, (6) Cummings devices, (7) microtexts, and (8) routine manipulations.
