Long‐term declines in winter body mass of tits throughout Britain and Ireland correlate with climate change

Ecology and Evolution, 2019
The optimum body mass of passerine birds typically represents a trade‐off between starvation risk, which promotes fat gain, and predation pressure, which promotes fat loss to maintain maneuvrability.

Body mass index: a measure of fatness or leanness?

, 1995
The relationship between body fat and stature-adjusted weight indices was explored. Assuming the term height’ is a valid indicator of a subject’s lean body mass, heighplweight was shown to be an accurate measure of percentage lean body mass and, as such,

A Refined Method for Studying Foraging Behaviour and Body Mass in Group-Housed European Starlings

Animals, 2022
Laboratory experiments on passerine birds have been important for testing hypotheses regarding the effects of environmental variables on the adaptive regulation of body mass.

Weighing the evidence for a body mass-regulating gravitostat [PDF]

Proceedings of the National Academy of Sciences, 2018
The intriguing paper by Jansson et al. (1) reports the identification of a body mass-regulating homeostat that operates in rodents independently of leptin. In response to implantation of capsules weighing 15% of body weight the authors observed that ∼80% of this load was offset by a reduction in biological body weight.

Apparent mass of small children: Modelling [PDF]

, 2007
Mass-spring-damper models are widely available for quantifying the whole-body vibration characteristics of primates, human adolescents and human adults, but no models have previously been developed for small children.

Winter body mass and over-ocean flocking as components of danger management by Pacific dunlins [PDF]

, 2010
Background We compared records of the body mass and roosting behavior of Pacific dunlins (Calidris alpina pacifica) wintering on the Fraser River estuary in southwest British Columbia between the 1970s and the 1990s. 'Over-ocean flocking' is a relatively

Increased weight loading reduces body weight and body fat in obese subjects – A proof of concept randomized clinical trial

EClinicalMedicine, 2020
Background: Recently we provided evidence for a leptin-independent homeostatic regulation, the gravitostat, of body weight in rodents. The aim of the present translational proof of concept study was to test the gravitostat hypothesis in humans.

A new method for measuring treadmill belt velocity fluctuations: effects of treadmill type, body mass and locomotion speed

Scientific Reports, 2021
Treadmills are essential to the study of human and animal locomotion as well as for applied diagnostics in both sports and medicine. The quantification of relevant biomechanical and physiological variables requires a precise regulation of treadmill belt ...

Current State of SLC and ABC Transporters in the Skin and Their Relation to Sweat Metabolites and Skin Diseases

Proteomes, 2021
With a relatively large surface area (2 m2) and 15% of total body mass, the skin forms the largest organ of the human body. The main functions of the skin include regulation of body temperature by insulation or sweating, regulation of the nervous system,
