WR23123Quantifying the accuracy of location data and spatial ecology inferences from GPS tags in two rare, co-occurring turtle species differing in habitat use
GPS tags are used to study animal spatial ecology because they can remotely obtain huge numbers of locations without disturbance to animals. We assessed how variation in accuracy of locations from GPS tags affected estimated home-range sizes and inferred macrohabitat use in co-occurring turtles. Canopy cover, ground cover, and submersion underwater reduced the number and accuracy of locations from GPS tags, and data screening increased accuracy of estimates regarding habitat use and home-range size from GPS tag data.
