“…It is also hypothesized that leptin contributes to maintaining body mass by regulating food intake and energy expenditure (Friedman and Halaas 1998). Furthermore, the positive correlation between serum leptin levels and body fat mass has been found in many small mammals including Apodemus chevrieri (Zhu et al 2011a) and Apodemus draco (Zhu et al 2013a). Lactation also had significant effects on serum leptin levels in some small mammals (Aoki et al 1999;Seeber et al 2002).…”

“…E. miletus were stabilized in the metabolic chamber for at least 60 min prior to the RMR measurement, and oxygen consumption was recorded for at least 120 min at 1-min intervals. Ten stable consecutive lowest readings were taken to calculate RMR (Zhu et al 2013a). The method used for calculating the metabolic rate is detailed in Hills (1972).…”

Background: It has been advocated that variation in resting metabolic rate (RMR) may affect the reproductive performance of female animals. In order to investigate the relationships between RMR and reproductive output in lactating Eothenomys miletus, body mass, RMR, food intake, litter size and mass, as well as the weight of visceral organs and gastrointestinal tract were measured in the female E. miletus prior to reproduction and at late lactation. Results: It showed that RMR was 39.62% higher at late lactation than prior to reproduction. There was no significant correlation between RMR prior to reproduction and reproductive output. However, RMR at late lactation was positively correlated with body mass, food intake, litter size and mass, and weight of visceral organs and gastrointestinal tract at late lactation, within which RMR was more related to gastrointestinal tracts than the visceral organs. Moreover, serum leptin levels were positively correlated with body fat mass, RMR, and food intake at late lactation. Conclusions: Our data supported the hypothesis that animals with higher RMR during lactation may have a greater digestion and absorption capacity in the digestive system for absorbing energy and may be able to devote more energy for reproduction. Leptin may participate in the regulation of body mass in lactating E. miletus.

Ecogeographical rules predict an association between specific adaptive morphological/physiological traits and latitude, elevation or cooler climates. Such ecogeographical effects are often expressed most clearly in widely distributed species due to continuous selective adaptation occurring over their geographic range. Based on 40 population sampling sites of 116 adult individuals (female, ; male, ) across an elevational range of 191–2573 m, we tested whether morphological traits accorded with predictions of Bergmann’s rule, Allen’s rule and Hesse’s rule for the South China field mouse (Apodemus draco). The effects of elevation on body size, appendage length and heart size were tested by fitting Linear Mixed-Effects Models. None conformed to Bergmann’s, Allen’s or Hesse’s rule. Clines in body size opposed Bergmann’s rule, and foot and snout length ratios opposed Allen’s rule. We conclude that South China field mice, a widely distributed species, exhibit an acute thermoregulation mechanism in which in colder conditions body sizes decrease – as opposed to altering heart sizes or surface area to volume ratios – requiring less energy to regulate body temperatures. Also, there was a stronger selective pressure to increase partial appendage lengths (i.e., foot and snout) to adapt to the specific environment (e.g. longer period of snow cover, up to 2573 m) rather than on a general shortening of appendages to cope with colder conditions.
