Scale effects between body size and limb design in quadrupedal mammals. [PDF]

PLoS ONE, 2013
Recently the metabolic cost of swinging the limbs has been found to be much greater than previously thought, raising the possibility that limb rotational inertia influences the energetics of locomotion.

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

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

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.

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.

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.

Recognition of ecosystem functional optima allows early detection of eutrophication in coral reef lagoons using seagrass meadows as bioindicators

iScience
Summary: An analysis of the impact on seagrass ecosystems of the high nutrient levels recently reported for the Mexican Caribbean revealed major structural, floristic, and community transformations over 20 years, but no adverse effects; rather ...

Stand Structure Impacts on Forest Modelling

Applied Sciences, 2022
Modelling is essential in forest management as it enables the prediction of productions and yields, and to develop and test alternative models of silviculture.

Impact of low sperm competition on male reproductive trait allometries in a bush-cricket

BMC Evolutionary Biology, 2019
Background Studying reproductive trait allometries can help to understand optimal male investment strategies under sexual selection. In promiscuous mating systems, studies across several taxa suggest that testes allometry is usually positive, presumably ...
