Evolution of static allometry and constraint on evolutionary allometry in a fossil stickleback [PDF]

open access: yesJournal of Evolutionary Biology, 2022
Allometric scaling describes the relationship of trait size to body size within and among taxa. The slope of the population‐level regression of trait size against body size (i.e.

Allometry and sexual dimorphism of the Neotropical freshwater anomuran Aegla marginata Bond-Buckup & Buckup, 1994 (Crustacea, Anomura, Aeglidae)

open access: yesNauplius, 2017
This study analyzes ontogenetic allometry in Aegla marginata Bond-Buckup & Buckup, 1994, a freshwater crustacean, in order to evaluate the growth pattern and the presence of sexual dimorphism, using a multivariate approach.

Multivariate allometry

open access: yes, 1996
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 ...

Matters of scale : positive allometry and the evolution of male dimorphisms [PDF]

open access: yes, 2005
The developmental independence of alternative phenotypes is key to evolutionary theories of phenotypic plasticity and the origins of diversity. Male dimorphisms associated with alternative reproductive tactics are widely cited examples of such ...

Height-diameter allometry of tropical forest trees [PDF]

open access: yes, 2010
Tropical tree height-diameter (H:D) relationships may vary by forest type and region making large-scale estimates of above-ground biomass subject to bias if they ignore these differences in stem allometry.

The allometry of ornaments and weapons [PDF]

open access: yesProceedings of the National Academy of Sciences, 2006
Exaggerated male traits that have evolved under sexual selection include ornaments to attract mates and weapons to deter rivals. Data from studies of many such traits in diverse kinds of organisms show that they almost universally exhibit positive allometries.

Ontogenetic allometry of the Beagle [PDF]

open access: yesBMC Veterinary Research, 2013
AbstractBackgroundMammalian juveniles undergo dramatic changes in body conformation during development. As one of the most common companion animals, the time line and trajectory of a dog’s development and its body’s re-proportioning is of particular scientific interest. Several ontogenetic studies have investigated the skeletal development in dogs, but

The genetic control of leaf and petal allometric variations in Arabidopsis thaliana

open access: yesBMC Plant Biology, 2020
Background Organ shape and size covariation (allometry) factors are essential concepts for the study of evolution and development. Although ample research has been conducted on organ shape and size, little research has considered the correlated variation

Commentary: The ecological and evolutionary implications of allometry

open access: yes, 2022
Allometry—the study of proportional growth of body parts, and the relationship of body size to an organism’s morphology, physiology and behaviour—is a fundamental influencer of ecological and evolutionary diversity.

Modelling tree height-diameter allometry of Chinese fir in relation to stand and climate variables through Bayesian model averaging approach

open access: yesSilva Fennica, 2021
Tree height-diameter allometry reflects the response of specific species to above and belowground resource allocation patterns. However, traditional methods (e.g.
