Moving in the real world: tortoises take the plunge to cross steep steps

摘要: Despite exhibiting low velocity and limited agility, many tortoises undertake large scale movements must overcome various obstacles, notably in populations living hilly or rocky habitats. Although crucial, studies exploring how move complex irregular environments are scarce. In this context, we examined an important behavioural trait: (Testudo hermanni) deal with step-like obstacles. their natural habitat, individuals were positioned a challenging situation: they placed on bench approximately 50 cm high, observed over 10-min period. We compared the behaviour of (taking risk to ‘jump’ waiting) from two contrasted habitats: flat versus rugged (crisscrossed by cliffs steps). Individuals habitat reluctant jump, whereas most jumped. Immature less willing jump larger more experienced adults. These results suggest that habitats increase boldness. addition fundamental findings, these may have conservation value assist improving translocation strategies for endangered tortoise populations. © 2013 The Linnean Society London
