Ontogenetic scaling patterns and functional anatomy of the pelvic limb musculature in emus (Dromaius novaehollandiae) [PDF]

, 2014
Emus (Dromaius novaehollandiae) are exclusively terrestrial, bipedal and cursorial ratites with some similar biomechanical characteristics to humans. Their growth rates are impressive, as their body mass increases eighty-fold from hatching to adulthood ...

Minimizing Bias in Biomass Allometry: Model Selection and Log‐Transformation of Data [PDF]

, 2011
Nonlinear regression is increasingly used to develop allometric equations for forest biomass estimation (i.e., as opposed to the traditional approach of log‐transformation followed by linear regression).

Allometric scaling and allocation patterns: Implications for predicting productivity across plant communities

Frontiers in Forests and Global Change, 2023
As the application of allometry continues to expand, the variability in the allometry exponent has generated a great deal of debate in forest ecology. Some studies have reported counterintuitive values of the exponent, but the sources of such values have

Range-based techniques for discovering optimality and analyzing scaling relationships in neuromechanical systems [PDF]

, 2009
In this paper, a method for decoupling the neuromuscular function of a set of limbs from the role morphology plays in regulating the performance of an activity is introduced.

Adaptation and plasticity in aboveground allometry variation of four pine species along environmental gradients

Ecology and Evolution, 2016
Plant species aboveground allometry can be viewed as a functional trait that reflects the evolutionary trade‐off between above‐ and belowground resources. In forest trees, allometry is related to productivity and resilience in different environments, and

A Fractional Probability Calculus View of Allometry

Systems, 2014
The scaling of respiratory metabolism with body size in animals is considered by many to be a fundamental law of nature. An apparent corollary of this law is the scaling of physiologic time with body size, implying that physiologic time is separate and ...

Male and female genital allometry in Habrobracon hebetor (Hymenoptera: Braconidae) [PDF]

Iranian Journal of Animal Biosystematics, 2021
This is particularly apparent within the insects that show high variations in genitalic form between closely related species. Static allometry is one of the effective approaches for quantification of such variation.

The scaling of postcranial muscles in cats (Felidae) I: forelimb, cervical, and thoracic muscles [PDF]

, 2016
The body masses of cats (Mammalia, Carnivora, Felidae) span a ~300‐fold range from the smallest to largest species. Despite this range, felid musculoskeletal anatomy remains remarkably conservative, including the maintenance of a crouched limb posture at

Patterns of ontogenetic evolution across extant marsupials reflect different allometric pathways to ecomorphological diversity

Nature Communications, 2023
The relatively high level of morphological diversity in Australasian marsupials compared to that observed among American marsupials remains poorly understood.

Three-dimensional geometric analysis of felid limb bone allometry.

PLoS ONE, 2009
BackgroundStudies of bone allometry typically use simple measurements taken in a small number of locations per bone; often the midshaft diameter or joint surface area is compared to body mass or bone length.
