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.

An allometry perspective on crops [PDF]

New Phytologist
SummaryUnderstanding trait–trait coordination is essential for successful plant breeding and crop modeling. Notably, plant size drives variation in morphological, physiological, and performance‐related traits, as described by allometric laws in ecology.

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 ...

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.

Amphibian Intestine Allometry [PDF]

Journal of Morphology
ABSTRACT Across four large vertebrate groups—fish, reptiles, birds and mammals— intestine length has been shown to scale hyper‐allometrically with body mass (BM), at an exponent higher than the geometric (isometric) expectation, 0.33. So far, amphibians have not been investigated in this respect.

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 ...

Canine evolution in sabretoothed carnivores: natural selection or sexual selection? [PDF]

PLoS ONE, 2013
The remarkable elongated upper canines of extinct sabretoothed carnivorous mammals have been the subject of considerable speculation on their adaptive function, but the absence of living analogues prevents any direct inference about their evolution.

Stand Structure Impacts on Forest Modelling

Applied Sciences, 2022

Retrospective and Prospective Human Intravenous and Oral Pharmacokinetic Projection of Dipeptidyl peptidase-IV Inhibitors Using Simple Allometric Principles – Case Studies of ABT-279, ABT-341, Alogliptin, Carmegliptin, Sitagliptin and Vildagliptin

Journal of Pharmacy & Pharmaceutical Sciences, 2015
Purpose: The purpose of this exercise was to explore the utility of allometric scaling approach for the prediction of intravenous and oral pharmacokinetics of six dipeptidy peptidase-IV (DPP-IV) inhibitors viz. ABT-279, ABT-341, alogliptin, carmegliptin,
