Method synopsis

Calculation of individual animal home ranges using 95% minimum convex polygons from location data, with specific criteria for minimum observation requirements.

Synthesized from method descriptions across 2 papers using this protocol.

Procedure from a recent peer-reviewed implementation

Steps below were extracted from the most recent peer-reviewed implementation of this protocol in the corpus — Habitat selection in a fluctuating ground squirrel population: Density - dependence and fitness consequences (2022), Ecology and Evolution. Implementations in other papers (listed below) may differ.

1. Home range calculation
   Calculated annual home ranges using 95% minimum convex polygons through package adehabitatHR (Calenge, 2006) in R software version 3.6.1 (R Core Team, 2019). Included only females with ≥55 independent observations within given year and observed across ≥20 different calendar days each year.
   Quantities: ≥55 observations per individual per year, ≥20 different calendar days, 95% minimum convex polygonsDuration: Annual analysis for each year 1996-2006Conditions: Post-processing of field observation data
   Equipment: R software version 3.6.1, adehabitatHR package

Typical Equipment

• R software version 3.6.1
• adehabitatHR package

Output Measurements

• home range boundaries
• home range size
• habitat composition within ranges
