“…In Taim Ecological Station, in the state of Rio Grande do Sul, Brazil (Fig. 8.1 ), groups included circa 58% adults, 25% juveniles, and 17% infants (Garcias and Bager 2009 ) . Age structures may also differ between the two capybara species: Aldana-Domínguez et al ( 2002 ) found a predominance of adults in populations of H. hydrochaeris in Colombia, but a more balanced adult to juvenile ratio was found by Ballesteros ( 2001 ) for Hydrochoerus isthmius .…”

“…Capybaras are the world's largest rodent and adults stand about 50 cm tall and can weigh around 54 kg (males) -62 kg (females) (Eisenberg & Redford 1999, Ferraz et al 2005. These rodents of unusual size are considered food and habitat generalists, have high reproductive capacity, and combined with a decline of large predators, they can reach high population densities in anthropogenic landscapes, including the central region of São Paulo State (Verdade & Ferraz 2006, Garcias & Bager 2009. Because of the size and weight of capybara and their abundance, collisions with vehicles are a serious concern.…”

“…A census performed in the State of Rio Grande do Sul by Garcias and Bager (2009) reported a 6.6 ± 0.1 female per male ratio for capybaras. The same study stated that capybaras are animals that live in groups ranging from two to 40 individuals and each flock has a dominant male that establishes a harem.…”
