bearmove
Description
Data set containing observed movement rates and associated average heart rates of 7 black bears in Minnesota.
Usage
bearmove
Format
A data frame with 2768 rows and 10 variables:
log.movedouble log movement rate, where movement rate is calculated using the distance between successive telemetry obsevartions divided by the time between observations in meters/hour.
hrinteger heart rate measured using implanted transmitters
Seasoncharacter Season of the observation (Fall, Spring, or Summer)
DayNightcharacter Timing of the observation (Day or Night)
Sexcharacter sex of the bear (Male or Female)
Stagecharacter categorical variable equal to Male, Female without cubs (Fem)), or Female with Cubs (CubPrep) Pre
julianinteger Julian day of the observation
BearIDinteger unique identifier associated with each bear
Yearinteger Year of the observation
BearIDYearinteger unique label assigned to each combination of bear + year

Cardiac biologgers made by Medtronic, plc (Reveal XT Model 9529) were surgically implanted into wild American black bears (Ursus americanus) in northern Minnesota by medical professionals. The biologger data collected from these individual bears measured the heart rate ("hr") of each animal continuously but only saved one average value during each day time (collected from 08:00–20:00) and night time (collected from 00:00–04:00) period on each date ("DayNight"). The associated GPS-locations were collected using both store-on-board GPS units and Iridium satellite collars. We calculated the movement rate (meters/hour) by dividing measured step lengths (i.e., straight-line distances between consecutive GPS observations) by the length of time between locations. We only included locations collected within six hours of one another and reported the log of the mean movement rates ("log.move") occurring during each of the associated daytime and nighttime heart rate interval collection periods. See Ditmer et al. 2015 for further information on this study.
