mammalsleep: Mammal sleep data
Description
Dataset from Allison and Cicchetti (1976) of 62 mammal
species on the interrelationship between sleep, ecological,
and constitutional variables. The dataset contains missing
values on five variables.source

Allison and Cicchetti (1976) investigated the
interrelationship between sleep, ecological, and
constitutional variables. They assessed these variables
for 39 mammalian species. The authors concluded that
slow-wave sleep is negatively associated with a factor
related to body size. This suggests that large amounts of
this sleep phase are disadvantageous in large species.
Also, paradoxical sleep (REM sleep) was associated with a
factor related to predatory danger, suggesting that large
amounts of this sleep phase are disadvantageous in prey
species.
