FERRAZ, Katia Maria Paschoaletto Micchi de Barros; BONACH, Kelly and VERDADE, Luciano Martins. Relationship between body mass and body length in capybaras (Hydrochoerus hydrochaeris). Biota Neotrop. [online]. 2005, vol.5, n.1, pp. 197-200. ISSN 1676-0611. http://dx.doi.org/10.1590/S1676-06032005000100020.
As a part of a management program we captured 39 capybaras (Hydrochoerus hydrochaeris) in an agroecosystem at the east central region of the State of São Paulo, Brazil from March 2001 to May 2002. Average adult male body mass was 54.1 ± 8.05 kg, and average adult female body mass was 62.0 ± 12.03 kg. Average juvenile male body mass was 23.0 ± 8.28 kg, and average juvenile female body mass was 26.7 ± 5.86 kg. Males and females presented a significant variation in the allometric relation between body mass and body length. Body mass and body length had a high correlation for both adult males and adult females. These results from capybaras in agroecosystem might be relevant for further management programs.
