Brain size, body size and longevity [PDF]

open access: yesInternational Journal of Obesity, 2010
In this analysis, we bring together two research fields that have never been associated before: the clinical issue 'Quételet's body-mass index and longevity' and the comparative biological issue 'body-brain allometry'. Comparison of medical and biological data supports the view that body mass index is just a one-to-one mapping of the body-brain-energy ...

Scaling body size fluctuations [PDF]

open access: yesProceedings of the National Academy of Sciences, 2013
The size of an organism matters for its metabolic, growth, mortality, and other vital rates. Scale-free community size spectra (i.e., size distributions regardless of species) are routinely observed in natural ecosystems and are the product of intra- and interspecies regulation of the relative abundance of organisms of different sizes.

The effect of attention on body size adaptation and body dissatisfaction

open access: yesRoyal Society Open Science, 2022
Attentional bias to low-fat bodies is thought to be associated with body dissatisfaction—a symptom and risk factor of eating disorders. However, the causal nature of this relationship is unclear.

Atmospheric hypoxia limits selection for large body size in insects [PDF]

open access: yes, 2008
Recent geological models indicate a marked increase in atmospheric oxygen partial pressure (aPO~2~) to 32 kPa in the Permo-Carboniferous (approx. 300 million years ago), subsequently falling to 13 kPa in the Triassic^1^.These aPO~2~ changes have been ...

Larger mammalian body size leads to lower retroviral activity [PDF]

open access: yes, 2014
Retroviruses have been infecting mammals for at least 100 million years, leaving descendants in host genomes known as endogenous retroviruses (ERVs). The abundance of ERVs is partly determined by their mode of replication, but it has also been suggested ...

Insights into body size variation in cetaceans from the evolution of body-size-related genes

open access: yesBMC Evolutionary Biology, 2019
Background Cetaceans exhibit an exceptionally wide range of body size, yet in this regard, their genetic basis remains poorly explored. In this study, 20 body-size-related genes for which duplication, mutation, or deficiency can cause body size change in

Geographic body size variation in ectotherms: effects of seasonality on an anuran from the southern temperate forest [PDF]

open access: yes, 2015
Indexación: Web of Science; Scopus.Background: Body size variation has played a central role in biogeographical research, however, most studies have aimed to describe trends rather than search for underlying mechanisms.

Does Ethnicity Influence Body‐Size Preference? A Comparison of Body Image and Body Size [PDF]

open access: yesObesity Research, 2002
AbstractObjective: Obesity is most common in the United States among women of ethnic minority groups (black and Hispanic). Researchers have hypothesized that these subcultures are more accepting of overweight figures. The purpose of this study was to examine body image and body size assessments in a large community sample of men and women.Research ...
