Abstract
Many organisms face alternative selective pressures across cyclically changing environments such as the diel cycle. Energetic and spatial constraints, among other issues, preclude independent day and nighttime or sleeping and wakeful responses to these contrasting sets of selective forces. We tested for behavioral similarity in microhabitat use during daytime wakeful and nighttime sleeping periods in Anolis lizards. We collected 1256 data points of sleeping perch height and substrate for 51 species and compared these data to published data on active perch use for these species. We demonstrate that species perch at similar heights but use significantly different perch substrates during sleep and wakefulness. The diel similarity in perch height may indicate a surfeit of adequate sleeping perches within a species' home range. The difference in perch substrate, wherein individuals tend to sleep on compliant perches, likely reflects the special predation risks encountered at night during sleep.

Data files
DATA_DBI24May2026.2.xlsx and DBI5125May2026.xlsx
Data are in the files "DATA_DBI24May2026.2.xlsx" and "DBI5125May2026.xlsx". These correspond to the complete ('DBI51...') and reduced ('DATA_DBI...') datasets.
Variables (columns) in the data files include:
- species (species code);
- LNDPH (natural log of mean species height in meters);
- DAYFLMSY (% of individuals of a species observed on compliant perches);
- NIGHTFLMSY (% of individuals of a species observed sleeping on compliant perches);
- LNNPH (natural log of mean species height in meters);
- nNight (number of observations of sleeping individuals, by species).
Empty cells occur in cases where n is unknown.

Analyses files
R Analyses are in files "anolis_analyses_DBI51.R" and "anolis_analyses_DATA_DBI.R". R file 'anolis_analyses_DBI51.R' describes and implements phylogenetic least squares analyses comparing night versus day perch heights and night versus day use of compliant perches, as well as a Monte Carlo height similarity test, for the dataset of 51 species. R file 'anolis_analyses_DATA_DBI.R' describes and implements phylogenetic least squares analyses comparing night versus day perch heights and night versus day use of compliant perches, as well as a Monte Carlo height similarity test, for the dataset of 30 species.
