Sleep in Mammals : Ecological and Constitutional Correlates

  title={Sleep in Mammals : Ecological and Constitutional Correlates},
  author={John J. Gilbert},
  year={2007}
}
The interrelationships between sleep, ecological, and constitutional variables were assessed statisticallyfor 39 mammalian species. Slow-wave sleep is negatively associated with a factor related to body size, which suggests that large amounts of this sleep phase are disadvantageous in large species. Paradoxical sleep is associated with a factor related to predatory danger, which suggests that large amounts of this sleep phase are disadvantageous in prey species. Every mammalian species studied…

A phylogenetic analysis of the correlates of sleep in birds

TLDR
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.

A Phylogenetic Analysis of Sleep Architecture in Mammals: The Integration of Anatomy, Physiology, and Ecology

TLDR
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.

Phylogenetic Analysis of The Ecology and Evolution of Mammalian Sleep

TLDR
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.

Re-examining extreme sleep duration in bats: implications for sleep phylogeny, ecology, and function

TLDR
The evidence for the characterization of bats as extreme sleepers is re-examined and whether it provides a useful representation of the sleep behavior of Chiroptera is discussed, suggesting temperature-dependent changes in the duration and electroencephalographic profile of sleep suggest that bats represent a unique model for investigating the relationship between sleep and torpor.

TLDR
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.

Energetic constraints, not predation, influence the evolution of sleep patterning in mammals.

TLDR
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.
