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

Royal 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.

Evolution of sexual dimorphism of wing shape in the Drosophila melanogaster subgroup [PDF]

BMC Evolutionary Biology, 2009
Background Sexual dimorphism of body size has been the subject of numerous studies, but few have examined sexual shape dimorphism (SShD) and its evolution.

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

EJNMMI 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

Plant 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,

Tallo: A global tree allometry and crown architecture database

Global Change Biology, 2022
Data capturing multiple axes of tree size and shape, such as a tree's stem diameter, height and crown size, underpin a wide range of ecological research—from developing and testing theory on forest structure and dynamics, to estimating forest carbon ...

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

PeerJ, 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.

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

Journal 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.

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

PeerJ, 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

Dynamic allometry in coastal overwash morphology [PDF]

, 2020
Allometry refers to a physical principle in which geometric (and/or metabolic) characteristics of an object or organism are correlated to its size. Allometric scaling relationships typically manifest as power laws.
