Commentary on energy, foraging and predation
Compare sleep habits across species. Zeppelin: small Animals-high metabolic rates-sleep more. Alison- animals with high predation risk sleep less, rabbits are an exception. Capellini says energy conservation hypothesis is wrong, pred/foragrightj

What is the combined approach for sleep.
Sleep should have 2 functions: occupying unproductive hours and energy conservation. Horne: core and optional sleep

Outside cappellini's study for mammalian sleep
Collected data from procedures that were standardised and used land mammals. Found: small mammals with high metabolic rate slept less (does not support) is a link between foraging and sleeping
