Effect of mink weight on persistence. a shows the relationship between animal weight and the median and maximum number of dives per cluster, and b—per AAS. The dashed vertical line indicates the break in body weight between males (>1 kg) and females (<1 kg). Data points are one deployment on one individual; in some cases, there were two or three deployments on the same individual (see Additional file 1 for deployment details). Solid lines show the model fit with individual included as a random effect.
