contiguos de 5 x 9 m. cada uno, dentro de una porqueriza. La dependencia y tolerancia a la presencia humana fué total a las 8 semanas en los juveniles y más pronto en los subadultos (2 semanas). La conducta agresiva es mayor en comederos adyacentes y semicirculares que en los separados linealmente unos de otros. El 49.77% de las veces los individuos juveniles realizan todas las actividades a menos de 0.5 m. mientras que sólo el 34.83 % de los subadultos lo hacen a la misma distancia. Es posible encontrar el 77.59% de las veces a cualquier individuo subadulto a una distancia mínima de entre 0.0 y 1.5 m. de otro, mientras que los juveniles lo están el 84% de las veces. Del estudio se deduce que los chigüiros se adaptan fácilmente al cautiverio y toleran altas densidades.
behaviour is more frequent in adyacent and semicircular feeders than in those lineally separated. The 49.77% of the times (N =424), juveniles individuals carried out their activities in less than 0.5 m., whereas only 34.83 % of the subadults did it at the same distance. It is possible to find any subadult individual 77.5% of the time at a minimun interindividual distance ranging between 0.0 and 1.5 m., whereas for the juveniles the possibility is 84% of the time. From the study is easily established that the capybaras
are readily adaptable to captivity and tolerate rather high densities.
