Abstract
El estudio se realizó en el Centro de Reproducción y Conservación de Primates no
Humanos del Instituto Veterinario de Investigaciones Tropicales y de Altura (IVITA),
con el objetivo de determinar patrones de comportamiento de las distintas
modalidades de parejas de Aotus nancymaae bajo condiciones de cautiverio para
obtener el modelo de emparejamiento ideal para la reproducción. Se evaluó
presupuestos de actividades, persistencia de la pareja, número de eventos
reproductivos y registro de interacciones negativas en 12 parejas formadas en
función de edades y experiencia reproductiva. Parejas conformadas por hembra
con experiencia y macho sin experiencia reproductiva y de edades de 14 meses
promedio, dedicaron en promedio dentro de su presupuesto de actividades, al acto
de posicionarse en percha con un tiempo de 49.9 minutos, al de posicionarse en el
nidal con 39.8 minutos y a alimentarse con un tiempo de 17.5 minutos. El
emparejamiento conformado por Hembras y Machos sin experiencia presentó el
menor promedio en los presupuestos de actividades; asimismo, este grupo
presenta el mayor número de crías (13), seguido por la combinación de Macho con
experiencia y Hembra sin experiencia con 8 crías. Se hace necesario completar
patrones de actividades diurnos de la especie, así como continuar con las
evaluaciones en diferentes fases lunares para comparar los resultados obtenidos
en el presente estudio y realizar estudios para conocer los despliegues de
comportamiento de la especie en las distintas etapas del manejo como partos,
lactancia, entre otros.
The study was conducted at the Center for Reproduction and Conservation of Nonhuman Primates of the Veterinary Institute for Tropical and High Altitude Research (IVITA), with the objective of determining behavioral patterns of the different modalities of Aotus nancymaae pairs under captive conditions in order to obtain the ideal mating model for reproduction. Activity budgets, pair persistence, number of reproductive events and record of negative interactions were evaluated in 12 pairs formed according to age and reproductive experience. Pairs formed by an experienced female and a male without reproductive experience and with an average age of 14 months, dedicated an average of 49.9 minutes to perching, 39.8 minutes to nesting and 17.5 minutes to feeding. The pairing of inexperienced males and females had the lowest average activity budgets; this group also had the highest number of broods (13), followed by the combination of experienced males and inexperienced females with 8 broods. It is necessary to complete diurnal activity patterns of the species, as well as to continue with the evaluations in different lunar phases to compare the results obtained in the present study and to carry out studies to know the behavioral displays of the species in the different stages of management such as parturition, lactation, among others.
