Regulation of body mass and management of childhood overweight
Pediatric Blood & Cancer, 2005AbstractObesity has become an increasingly important public health problem. Recent evidence suggests that obesity has become a close second to tobacco use as a preventable cause of death in the United States. During the past decade an increase in the prevalence of type 2 diabetes in adolescents has been observed.

Effects of weather on daily body mass regulation in wintering dunlin
Journal of Experimental Biology, 2002SUMMARYWe investigated the influence of changes in weather associated with winter storms on mass balance, activity and food consumption in captive dunlin (Calidris alpina) held in outdoor aviaries, and compared the aviary results with weather-related body mass differences in free-living dunlin collected at Bolinas Lagoon, California.

Photoperiodic regulation of body mass and fat reserves in the meadow vole
Physiology & Behavior, 1986Short photoperiods reduce both body mass and food intake of male meadow voles. To help determine whether the primary effect of short day lengths is on regulation of some component of body mass or on the control of food consumption, voles housed in a long photoperiod were provided rations equivalent to those consumed by animals in short day lengths ...

Social stimulation and regulation of body mass in female starlings
Animal Behaviour, 1997The influence of consexual social stimulation on the regulation of body mass in female European starlings, Sturnus vulgarisduring reproductive development was examined. Twenty-four pairs of birds were housed in three social stimulation treatments: (1) control, where birds were housed in visual isolation from their partner; (2) visual contact, pairs of ...

Strategic diel regulation of body mass in European robins
Animal Behaviour, 2000Stochastic dynamic programming (SDP) is a computational technique that has been used to model daily routines of foraging in small birds. A diurnal bird must build up its fat reserves towards dusk in order to avoid starvation during the night, when it cannot feed. However, as well as the benefits of avoiding starvation, storing fat imposes costs such as

Photoperiodic regulation of body mass, food intake, and reproduction in meadow voles
American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 1983Adult male voles were maintained for 10 wk in long or short photoperiods (14 or 10 h of light/day). A third group of animals housed in the long photoperiod was implanted with capsules containing melatonin. Body weight and food intake were measured weekly; various tissues were weighed and analyzed at the time of autopsy. After 10 wk, voles in the short

Seasonal thermogenesis and body mass regulation in plateau pikas (Ochotona curzoniae)
Oecologia, 2006Changes in photoperiod, ambient temperature and food availability trigger seasonal acclimatization in physiology and behavior of many animals. In the present study, seasonal adjustments in body mass and in several physiological, hormonal, and biochemical markers were examined in wild-captured plateau pikas (Ochotona curzoniae) from the Qinghai-Tibetan ...

Regulation of body fat mass by the gut microbiota: Possible mediation by the brain
Peptides, 2016New insight suggests gut microbiota as a component in energy balance. However, the underlying mechanisms by which gut microbiota can impact metabolic regulation is unclear. A recent study from our lab shows, for the first time, a link between gut microbiota and energy balance circuitries in the hypothalamus and brainstem. In this article we will review

Towards an Understanding of Physiological Body Mass Regulation: Seasonal Animal Models
Nutritional Neuroscience, 2000This review is based around a number of interlinked hypotheses that can be summarised as follows: (i) mammalian body mass is regulated, (ii) the mechanisms that effect this regulation are common to all mammalian species, including humans, (iii) the neurochemical substrates involved in long term body mass regulation and in determining the level of body ...

Body mass regulation and the daily singing routines of European robins
Animal Behaviour, 2002Stochastic dynamic programming (SDP) models of daily singing and foraging routines in birds relate an individual's fat reserves to the relative costs and benefits of singing and foraging at different times of day. Two central predictions of such models are that: (1) overnight loss of fat reserves is higher on colder nights, and (2) birds sing more at ...
