“…Reintroductions are appealing as they facilitate population restoration or augmentation of endangered or locally-extinct species without affecting the demography of other natural populations (Armstrong and Seddon, 2008;Bowkett, 2009). Under certain circumstances, however, captive-bred animals may face different types of genetic problems in captivity (see Robert, 2009), such as inbreeding depression (Ralls et al, 1988), genetic drift (Bryant and Reed, 1999), loss of genetic diversity (Neveu et al, 1998), and/or genetic adaptations to captivity that are deleterious in the wild (Frankham, 2008), possibly due to the small population size, the unnatural setting of captivity, artificial selection, or their interactions (Robert, 2009), which may limit or even prevent a particular behaviour from being learnt. While many studies have examined the viability of reintroduced animals, including whether they are capable of some movement and/or dispersal (Diefenbach et al, 2006;Ausband and Moehrenschlager, 2009), to our knowledge, no studies have explicitly determined whether reintroduced populations have retained their natural movement tendencies.…”
