Significance Endothermic animals must survive periods of seasonally lowered temperature, coincident with food supply. While we know much about hibernation and migration as survival strategies, the responses nonhibernating, nonmigrating species are more opaque, yet how these such is important to understand their potential susceptibility climate change. Here, report on a 13-y study lagomorph (plateau pika) from Qinghai-Tibetan Plateau. We show pikas suppress metabolism in winter exploit novel...
The stable isotopes of hydrogen (δ(2)H) and oxygen (δ(18)O) in human urine are measured during studies total energy expenditure by the doubly labeled water method, measurement body water, insulin resistance glucose disposal among other applications. An ultrasensitive laser absorption spectrometer based on off-axis integrated cavity output spectroscopy was demonstrated for simple inexpensive natural isotopic abundance isotopically enriched urine. Preparation analysis rapid (approximately 25...
SUMMARY Many small mammals respond to seasonal changes in photoperiod by altering body mass and adiposity. These animals may provide valuable models for understanding the regulation of energy balance. Here, we present data on field vole (Microtus agrestis) – a previously uncharacterised example photoperiod-induced mass. We examined effect increased day length mass, food intake, apparent digestive efficiency,body composition, de novo lipogenesis fatty acid composition adipose tissue...
