Telemetry without collars: performance of fur- and ear-mounted satellite tags for evaluating the movement and behaviour of polar bears

Table 1 Model selection of two-state hidden Markov models fit to terrestrial movements of subadult and adult male polar bears (9 individuals; 10 tracks) equipped with Argos- and GPS/Iridium-linked ear and fur tags on the sea ice or along coast of Hudson Bay between 2016 and 2022

Model	K	AIC_c	ΔAIC_c	Log Likelihood
temp	13	2327.796	0	−1164.898
–	11	2338.155	10.359	−1170.078
temp + temp²	15	2826.065	498.269	−1414.032

Models are defined in the Methods section; K is the number of parameters in the model, and ΔAIC_c is the Akaike information criterion of each model relative to the best fitting or most parsimonious model with the lowest AIC_c score. The intercept-only model (-) included no effect of temperature on state transition probabilities
