Body Temperature Series of Two Beavers

Description

Reynolds (1994) describes a small part of a study of the long-term temperature dynamics of beaver Castor canadensis in north-central Wisconsin. Body temperature was measured by telemetry every 10 minutes for four females, but data from a one period of less than a day for each of two animals is used there.

Usage

data(beavers)

Arguments

day Day of observation (in days since the beginning of 1990), December 12–13 (beaver1) and November 3–4 (beaver2).
time Time of observation, in the form 0330 for 3:30am
temp Measured body temperature in degrees Celsius
activ Indicator of activity outside the retreat

Format

The beaver1 data frame has 114 rows and 4 columns on body temperature measurements at 10 minute intervals.

The beaver2 data frame has 100 rows and 4 columns on body temperature measurements at 10 minute intervals.

Note

The observation at 22:20 is missing in beaver1.
