based mainly on food availability (Aliaga-Rossel, 2003) and it can travel fairly long distances
(60 km) in a single day, but has a tendency to remain in a single location. The waterfall
barricade has supported a low genetic richness of the Bolivian population relative to other
Inia populations (see Martínez-Agüero et al.'s chapter 7) and consequently it is more
vulnerable.
