Resumen
El estudio de fauna silvestre en cautiverio es aún incipiente en el Perú. El venado cola blanca, considerado una especie emblemática de los bosques secos del norte del país, no es una excepción. En Lima, bajo un plan de manejo autorizado, la Pontificia Universidad Católica del Perú (PUCP) alberga esta especie en su zoocriadero, lo que permite realizar estudios sistemáticos sobre su comportamiento en condiciones controladas. El presente trabajo analiza la supervivencia de los venados cola blanca en cautiverio durante un periodo de diez años (2011–2020). La metodología incluyó la recopilación y filtrado de datos oficiales del zoocriadero, el diseño experimental y el análisis estadístico mediante el método de Kaplan Meier y la regresión de Cox. Se evaluó la influencia de las variables independientes: sexo y origen de los individuos (nacidos en el zoocriadero, provenientes del plantel reproductor o bajo custodia). Los resultados muestran que la supervivencia de la población disminuyó a lo largo del periodo de estudio. El sexo no presentó una influencia significativa en la supervivencia; sin embargo, el origen sí fue un factor relevante: los individuos nacidos en el zoocriadero presentaron menor supervivencia en comparación con los demás grupos. Además, se evidenció que la reducción del área de manejo de 17 ha a 1.6 ha incrementó significativamente la densidad poblacional y generó cambios en las condiciones de manejo, constituyéndose en un posible factor asociado al aumento de la mortalidad.
The study of wildlife in captivity is still incipient in Peru. The white-tailed deer, considered an emblematic species of the dry forests in the north of the country, is no exception. In Lima, under an authorized wildlife management plan, the Pontifical Catholic University of Peru (PUCP) houses this species in its wildlife breeding center, allowing for systematic studies of its behavior under controlled conditions. This study analyzes the survival of white-tailed deer in captivity over a ten-year period (2011–2020). The methodology included the collection and filtering of official data from the breeding center, experimental design, and statistical analysis using the Kaplan-Meier method and Cox regression. The influence of two independent variables was evaluated: sex and origin of the individuals (born in the breeding center, from the reproductive stock, or under custody). The results show that population survival decreased over the study period. Sex did not have a significant influence on survival; however, origin proved to be a relevant factor: individuals born in the breeding center had lower survival compared to the other groups. Additionally, it was found that the reduction of the management area from 17 ha to 1.6 ha significantly increased population density and led to changes in management conditions, constituting a possible factor associated with increased mortality.
