2.3.2 Likelihood of GPS tags being used
A total of 140 studies were used to assess whether the type of tracking method used could be predicted by taxa, body mass of species and year. Resource tracking studies and reptile and fish species were omitted. We fit binomial GLMs to the outcome of studies using GPS tags with taxa (bird or mammal), body mass (g) and year of study (1978 – 2022) as fixed effects. Models with and without interaction terms were compared using Akaike Information Criterion (AIC) values, and the model with the lowest AIC was selected.
