What is a home range?
"that area traversed by the animal during its normal activities of food gathering, mating and caring for young. Occasional sallies outside the area, perhaps exploratory in nature, should not be considered as in part of the home range.” -Burt 1943
The most commonly cited definition is vague and does not provide a clear method for estimating the home range. So what should someone wanting to calculate home ranges do?
This is the second post on analyzing telemetry data in R.
I show a simple method to create trajectories to measure distance travelled, turning angles, and average speed.
Data and code available here.
The following is adapted from a workshop I ran at Trent University in January 2018. It is meant to be an introduction to using R to analyze movement patterns and home ranges from telemetry data. I have split the content into several smaller posts. In this first post, I format simulated telemetry data for spatial analyses and map points and paths overtop of Google Earth imagery with the ggmap package.
Code available at my GitHub page.
