Age and body size of Rana amurensis from northeastern China

open access: yesCurrent Zoology, 2011
Age and body size are two important demographic traits that determine the life history strategies of populations and species. We measured these two parameters of Rana amurensis, at a 900 m and a 500 m altitude site in northeastern China. At the two sites,

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 ...

Seeing the body distorts tactile size perception [PDF]

open access: yes, 2013
Vision of the body modulates somatosensation, even when entirely non-informative about stimulation. For example, seeing the body increases tactile spatial acuity, but reduces acute pain.

Body size evolution in insular speckled rattlesnakes (Viperidae : Crotalus mitchellii) [PDF]

open access: yes, 2010
Background Speckled rattlesnakes (Crotalus mitchellii) inhabit multiple islands off the coast of Baja California, Mexico. Two of the 14 known insular populations have been recognized as subspecies based primarily on body size divergence from putative ...

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

Owning an overweight or underweight body: distinguishing the physical, experienced and virtual body [PDF]

open access: yes, 2014
Our bodies are the most intimately familiar objects we encounter in our perceptual environment. Virtual reality provides a unique method to allow us to experience having a very different body from our own, thereby providing a valuable method to explore ...

Body size and food size in freshwater zooplankton [PDF]

open access: yesProceedings of the National Academy of Sciences, 1984
We used double-label liquid scintillation techniques to measure the efficiencies with which eight different-sized zooplankton species ingested four cell types relative to a standard cell type ( Chlamydomonas ). Efficiency ratios (ERs: clearance rate on cell type X ÷ clearance rate on Chlamydomonas
