Moving towards acceleration for estimates of activity-specific metabolic rate in free-living animals: the case of the cormorant. (2006, background): “in locomotion; Alexander 2003) or physiological /behavioural traits (e.g. hibernation/ torpor; Geiser 2004) is critical in survival and thus is a primary focus for natural selection (Brown et al .”
Could localized warm areas inside cold caves reduce mortality of hibernating bats affected by white-nose syndrome? (2010, background): “…normal hibernator spends over 99% of its time during winter in bouts of deep, prolonged torpor, during which Tb falls close to ambient temperature (Ta, 2–8˚C for cave-hibernating bats) and metabolic rate can be reduced to less than 1% of that during euthermic (ie non- torpid) periods (Geiser 2004).”
Cold acclimation recruits human brown fat and increases nonshivering thermogenesis. (2013, neutral): “2%) cold acclimation, which can be due to low or no NST in combination with lower temperatures of the extremities, causing a drop in metabolism in these regions (Arrhenius law) (14).”
Bats and Buildings: The Conservation of Synanthropic Bats (2015, background): “Many bats are also heterothermic, reducing their body temperature and consequently metabolic rate, during periods of adverse conditions, such as low resource abundance (insects, fruits, or nectar), low ambient temperature, or high rainfall (Geiser 2004).”
Stress, resource allocation, and mortality (2005, background): “Extreme examples of physiological responses are seen in a range of animal taxa, which reduce their energy requirements through hibernation or transient torpor, during adverse seasonal conditions (Geiser, 2004; Humphries et al., 2003; Lyman, 1982).”
A global heterothermic continuum in mammals (2013, background): “the metabolic consequences of less pronounced Tb variation (e.g. Bennett et al., 1993; Geiser, 2004), suggest the extent of metabolic variation introduced by Tb variation will overwhelm most of the fine-scale metabolic differentiation focused on in resting MR (RMR) studies.”
Huddling in groups leads to daily energy savings in free‐living African Four‐Striped Grass Mice, Rhabdomys pumilio (2006, background): “Animals may, for example, return to a central place such as a nest and reduce the energy cost of foraging (Charnov 1976; Orians & Pearson 1979), they may bask in the sunshine (Geiser, Goodship & Pavey 2002), they may allow body temperature to fall (Geiser 2004) or they may huddle in groups during pe”
Starvation physiology: reviewing the different strategies animals use to survive a common challenge. (2010, background): “…or aestivating animals have been thoroughly reviewed elsewhere (Gatten, 1985; Storey and Storey, 1990; Guppy et al., 1994; Hand and Hardewig, 1996; Guppy and Withers, 1999; Humpheries et al., 2003; Geiser, 2004), this review will focus on animals that remain relatively active during starvation.”
Adaptive phenotypic plasticity and resilience of vertebrates to increasing climatic unpredictability. (2010, background): “In endotherms, hypometabolism usually anticipates heterothermy, i.e. a drop in body temperature for a variable amount of time, from some hours (daily torpor) to several months (hibernation; Geiser 2004).”
Beyond the ‘3/4‐power law’: variation in the intra‐and interspecific scaling of metabolic rate in animals (2005, positive): “Using data on hibernating mammals (body mass=6– 80000 g) given in Geiser (2004), I have calculated a scaling exponent of 0.830¡0.073 (N=42) for torpid metabolic rate (corrected for body temperature using multiple regression) that is also significantly greater than 3/4.”
Thermal benefits of clustering during hibernation: a field test of competing hypotheses on Myotis sodalis (2008, background): “However, because T b of hibernating individuals usually is near T a (Geiser 2004), the rate of heat loss is low and energy conservation from clustering is minimal.”
Body mass dependent use of hibernation: why not prolong the active season, if they can? (2014, background): “Hence, smaller animals with somewhat higher mass-specific torpor metabolic rates (Geiser 2004) should have shorter torpor bouts.”
Individual flexibility in energy saving: body size and condition constrain torpor use (2013, background): “tion in body temperature and metabolic rate during periods of rest (Geiser 2004; Heldmaier, Ortmann & Elvert 2004).”
Daily torpor and hibernation in birds and mammals (2014, positive): “(iii) That phylogenetically informed regression analysis within hibernators and daily heterotherms, if maintaining these categories was justified by results of the above analyses, would support earlier findings (e.g. Geiser & Ruf, 1995; Geiser, 2004) suggesting that: (a) mean body mass of hibernator”
