Evolution of morphological allometry [PDF]

open access: yesAnnals of the New York Academy of Sciences, 2014
Morphological allometry refers to patterns of covariance between body parts resulting from variation in body size. Whether measured during growth (ontogenetic allometry), among individuals at similar developmental stage (static allometry), or among populations or species (evolutionary allometry), allometric relationships are often tight and relatively ...

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

open access: yesJournal of Evolutionary Biology, 2022
Abstract 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 .

Ontogenetic allometry of the Beagle [PDF]

open access: yesBMC Veterinary Research, 2013
AbstractBackgroundMammalian juveniles undergo dramatic changes in body conformation during development. As one of the most common companion animals, the time line and trajectory of a dog’s development and its body’s re-proportioning is of particular scientific interest. Several ontogenetic studies have investigated the skeletal development in dogs, but

The allometry of ornaments and weapons [PDF]

open access: yesProceedings of the National Academy of Sciences, 2006
Exaggerated male traits that have evolved under sexual selection include ornaments to attract mates and weapons to deter rivals. Data from studies of many such traits in diverse kinds of organisms show that they almost universally exhibit positive allometries.

The Allometry of Prey Preferences

open access: yesPLoS ONE, 2011
The distribution of weak and strong non-linear feeding interactions (i.e., functional responses) across the links of complex food webs is critically important for their stability. While empirical advances have unravelled constraints on single-prey functional responses, their validity in the context of complex food webs where most predators have ...

An allometry perspective on crops [PDF]

open access: yesNew 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.

Allometry of brain metabolism [PDF]

open access: yesProceedings of the National Academy of Sciences, 2013
Allometry refers to biological scaling relationships (1). With regard to metabolic rate, the earliest allometric studies demonstrated a complex inverse relationship between body size and resting metabolic rate (2⇓–4). Subsequent studies have focused, without much success, on describing the cellular mechanisms of this relationship.

Length–mass allometries in amphibians

open access: yesIntegrative Zoology, 2018
AbstractBody mass is rarely recorded in amphibians, and other body measurements (e.g. snout to vent length, SVL) are generally collected instead. However, length measurements, when used as proxies of body mass in comparative analyses, are problematic if different taxa and morphotypes are included.

Network allometry [PDF]

open access: yesGeophysical Research Letters, 2002
We derive a new allometric scaling law for loopless networks, which we confirm with studies on rivers, exact network results and computer simulations. We provide evidence suggesting that ensemble averaging of the allometric property (where individual realizations are different networks) leads to results in excellent accord with the known limit scaling ...

Implications of allometry [PDF]

open access: yesProceedings of the National Academy of Sciences, 2011
The thoughtful paper by Asner et al. (1) needs clarification. A major conclusion is that light detection and ranging (LiDAR)-based sampling combined with an allometric model of tree biomass that uses height measurements is significantly better than simply using the Intergovernmental Panel on Climate Change Tier 1 prescribed forest carbon values (2) for
