FERRAZ, Katia Maria Paschoaletto Michi de Barros; LECHEVALIER, Marrie-Anne; COUTO, Hilton Thadeu Zarate do  and  VERDADE, Luciano Martins. Damage caused by capybaras in a corn Field. Sci. agric. (Piracicaba, Braz.) [online]. 2003, vol.60, n.1, pp.191-194. ISSN 1678-992X.

Damage caused by capybaras in agroecossystems in Brazil has been frequently observed. The objective of this study was to describe and quantify the actual damage caused by capybaras in a corn field, aiming to get basic information on how, how much, and where these damage occur. Systematic sampling indicated that 26% of the planted area were damaged by capybaras, and the highest percentage of damage occurred on the border of the corn field (t=4.5698, p=0.0001). Damage in areas adjacent to a forest fragment was significantly higher (t=13.6198, p=0.0001), suggesting that the strategy of area utilization for feeding was related to the proximity of the resources "forest" and "water". Avoiding corn plantation in areas adjacent to forest fragments used by capybaras and, when possible, controlling capybara population may lead to a reduction of damage occurrence in agroecossystems.
