On weapons allometry and the form of sexual selection [PDF]

open access: yesRoyal Society Open Science
The study of trait scaling with body size (allometry) has a long history, and it has been argued that positive static allometry is an indicator of directional sexual selection.

Allometry correction in semi-quantitative analysis of dopamine transporter SPECT [PDF]

open access: yesEJNMMI Research
Background Striatal specific binding ratios (SBR) are widely used to support the interpretation of dopamine transporter SPECT scans. Automatic SBR computation often involves using affine transformations to map the individual SPECT images to an anatomical

The worldwide allometric relationship in anatomical structures for plant roots

open access: yesPlant Diversity, 2023
The cortex (i.e., absorptive tissue) and stele (transportive vascular tissue) are fundamental to the function of plant roots. Unraveling how these anatomical structures are assembled in absorptive roots is essential for our understanding of plant ecology,

Assessment of a Takagi–Sugeno-Kang fuzzy model assembly for examination of polyphasic loglinear allometry [PDF]

open access: yesPeerJ, 2020
Background The traditional allometric analysis relies on log- transformation to contemplate linear regression in geometrical space then retransforming to get Huxley’s model of simple allometry.

Monthly variations in growth pattern and condition factor of Periophthalmodon septemradiatus (Gobiiformes: Periophthalminae) living along the Bassac River in Viet Nam [PDF]

open access: yesPeerJ, 2022
Periophthalmodon septemradiatus (Hamilton, 1822) is a unique mudskipper living in the mudbanks from estuarine to riverine regions in the Vietnamese Mekong Delta (VMD), but there is no data on its growth patterns and condition factors that are helpful for

Effects of Competition on The Crown Width Allometry for Dominant Trees on Good Sites of Vegetative Clonal Teak (Tectona grandis Linn. f.) in Java, Indonesia

open access: yesJurnal Manajemen Hutan Tropika, 2019
The vegetative clonal teak is fast-growing, exhibits relatively uniform growth, and is sensitive to crown competition. The crown width dimension correlates positively with the size of the diameter (CW allometry).

Variation in the ontogenetic allometry of horn length in bovids along a body mass continuum

open access: yesEcology and Evolution, 2020
Allometric relationships describe the proportional covariation between morphological, physiological, or life‐history traits and the size of the organisms. Evolutionary allometries estimated among species are expected to result from species differences in

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

Allometric growth in the frontals of the Mongolian theropod dinosaur Tarbosaurus bataar [PDF]

open access: yesActa Palaeontologica Polonica, 2022
Tarbosaurus bataar is a sister taxon of the well-studied theropod dinosaur Tyrannosaurus rex, and numerous fossils of this tyrannosaurid have been discovered in the Upper Cretaceous Nemegt Formation of Mongolia. Although specimens of different sizes of

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.
