... Exploratory and foraging behaviors are linked in range-expanding populations, as shown by greater drive to eat novel foods in invading edge populations of birds (Liebl and Martin, 2014;Martin and Fitzgerald, 2005). Studies of island vs. mainland populations show greater displays of exploratory behaviors in recently colonized populations (Brodin et al., 2013;Stratton et al., 2021). In our study, if the greater propensity for exploration or foraging in northern populations relates to greater dispersal, it is possible that historical founders from these populations (located north of the historical sub-glacial refugia; Lee-Yaw et al., 2008) contributed to the vast post-Pleistocene movement of wood frogs northward to the Arctic Circle. ...

... Boldness, i.e. risk-taking behaviour in the presence of a predator threat, is expected to change in a way that matches predation risk on islands. The few studies focusing on the effect of insularity on boldness have found island common frogs (Rana temporaria) [62] and house mice (Mus musculus domesticus) [63] to be bolder than their mainland counterparts. Perhaps inspired by early (mostly anecdotal) accounts of island tameness (e.g. ...
