Abstract

We placed cage litter from black-footed ferrets (Mustela nigripes) down the burrows of black-tailed prairie dogs (Cynomys ludovicianus) each week from 10 March to 21 May 1996 on the Cathy Fromme Prairie near Fort Collins, Colorado to determine its effect on prairie dog behavior and reproduction. Ferret odors did not affect the number of prairie dogs remaining, number of burrows open and closed, percentage of burrows closed, and reproduction by prairie dogs on treatment compared to control plots. However, proportion of adult prairie dogs that appeared above ground 0.5 to 4.0 h after (compared to number that appeared immediately before) odors were applied was smaller on treatment compared to control plots ($F_{1,32}$ = 23.44, P < 0.0001). /// Colocamos basura de jaulas de hurón (Mustela nigripes) en las madrigueras de marmota de pradera cola-negra (Cynomys ludovicianus) cada semana entre el 10 de marzo y el 21 de mayo de 1996, en la pradera llamada Cathy Fromme Prairie, cerca de Fort Collins, Colorado, con el objeto de determinar su efecto en la conducta y en la reproducción de las marmotas de las praderas. Los olores del hurón no afectaron el número de marmotas de las praderas que permanecieron, ni el número de las madrigueras abiertas ni cerradas, ni el porcentaje de madrigueras cerradas, ni la reproducción de las marmotas en los sitios de tratamiento en comparación de los de control. Sin embargo, la proporción de marmotas de la pradera adultas que aparecieron en la superficie de la tierra entre 0.5 y 4.0 horas después de la aplicación de los olores fue menor en los sitios de tratamiento que en los de control, en comparación con el número de marmotas que aparecieron inmediatamente antes ($F_{1,32}$ = 23.44, P < 0.0001).
