Phylogenetic Analysis of The Ecology and Evolution of Mammalian Sleep
- Biology, PsychologyEvolution; international journal of organic evolution
It is found that basal metabolic rate correlates negatively rather than positively with sleep quotas, and that neither adult nor neonatal brain mass correlates positively with REM or NREM sleep times, which contradict hypotheses that invoke energy conservation, cognition, and development as drivers of sleep variation.
A phylogenetic analysis of the correlates of sleep in birds
- BiologyJournal of sleep research
The first quantitative analysis of sleep in a non‐mammalian taxon (birds) focusing on the daily amount of time spent in slow‐wave sleep (SWS) and rapid‐eye movement (REM) sleep as determined by electrophysiological methods suggests that further insight into the function of sleep across the animal kingdom may require an expansion of sleep research beyond the current mammalian paradigm.
Energetic constraints, not predation, influence the evolution of sleep patterning in mammals.
- Biology, PsychologyFunctional ecology
Neither sleep-cycle length nor phasing of sleep was significantly associated with three different measures of predation risk, undermining the idea that they represent anti-predator adaptations.
Sleep in a comparative context: Investigating how human sleep differs from sleep in other primates.
- Biology, PsychologyAmerican journal of physical anthropology
It is proposed that the risks and opportunity costs of sleep are responsible for shorter sleep durations in humans, with risks arising from terrestrial sleep involving threats from predators and conspecifics, and opportunity Costs because time spent sleeping could be used for learning, creating material objects, and socializing.
A Phylogenetic Analysis of Sleep Architecture in Mammals: The Integration of Anatomy, Physiology, and Ecology
- Biology, PsychologyThe American Naturalist
It is found that species with higher relative BMRs engage in less SWS, whereas species with larger relative brain masses engage in more REM sleep, and REM sleep was the only sleep variable strongly influenced by predation risk.

The Thermophysiology of Paradoxical Sleep
- BiologyNeuroscience and Behavioral Physiology
This review analyzes data on the interactions between PS and thermoregulation in thermally comfortable and extreme conditions and proposes the hypothesis that PS has a role in the synchronization and endogenous “build-up” of ultradian rhythms of visceral functions facilitating decreases in brain temperature to below the limit of “normothermia” and entry into torpor and hibernation.
A quantitative, theoretical framework for understanding mammalian sleep
- BiologyProceedings of the National Academy of Sciences
A general, quantitative theory for mammalian sleep that relates many of its fundamental parameters to metabolic rate and body size is developed and leads to predictions for sleep time, sleep cycle time, and rapid eye movement time as functions of body and brain mass.

It is proposed that sleep constitutes a period of dormancy in which energy is conserved to partially offset the increased energy demands of homeothermy and disruptions of circadian rhythms of sleep and wakefulness in humans produce impairments in mood and performance independent of total amounts of sleep obtained.
