Abstract
La presente investigación se centró en el análisis del comportamiento de vicuñas (Vicugna vicugna mensalis) pertenecientes a grupos familiares en los ecosistemas: Bofedal, pajonal y tólar, a lo largo de tres estaciones: seca, antes de lluvia y post lluvia. Estas vicuñas se manejan bajo la modalidad de silvestría en el área comunal de la Comunidad Campesina de San Cristóbal, Lucanas – Ayacucho. Para llevar a cabo este estudio se establecieron áreas de observación georreferenciadas evitando perturbaciones de animales domésticos. Se realizaron en total 332 observaciones, distribuidas en tres momentos entre octubre de 2021 y septiembre de 2022, empleando la técnica de muestreo focal al azar en 14 puntos de observación. Durante estas observaciones, se registraron una serie de comportamientos, como el pastoreo, estar de pie, vigilar, caminar, correr, descansar, acicalarse y amamantar, representados por proporciones en etogramas. Para el análisis de datos se emplearon el Test de Kruskal-Wallis para contrastar hipótesis y el Test de Dunn para comparaciones múltiples entre grupos independientes, con ajuste de probabilidad de Holm-Bonferroni para controlar errores. Los resultados indican que, las vicuñas exhiben variaciones estacionales en su comportamiento, con actividades como pastoreo, caminar, vigilar y correr más pronunciadas durante la temporada seca. El comportamiento varía según las estaciones: durante la temporada seca, hay una mayor tendencia a estar de pie, mientras que después de las lluvias, aumenta el tiempo de descanso. Además, se nota un incremento en el acicalado antes de las lluvias y una predominancia en el amamantamiento posteriormente, revelando patrones consistentes en cada temporada. A pesar de las variaciones estacionales, las vicuñas muestran un comportamiento consistente en diferentes ecosistemas, lo que sugiere una adaptabilidad generalizada. Sin embargo, se observan cambios en su comportamiento según la temporada, demostrando su capacidad de ajuste a distintos entornos como pajonales, bofedales y tolares
This research focused on analyzing the behavior of vicuñas (Vicugna vicugna mensalis) in family groups within the bofedal, pajonal, and tolar ecosystems over three seasons: dry, pre-rain, and post-rain. These vicuñas are managed under the wild management modality in the communal area of the San Cristóbal Peasant Community, Lucanas – Ayacucho. To carry out this study, georeferenced observation areas were established to avoid disturbances from domestic animals. A total of 332 observations were conducted, distributed over three periods between October 2021 and September 2022, using the random focal sampling technique at 14 observation points. During these observations, various behaviors were recorded, such as grazing, standing, watching, walking, running, resting, grooming, and nursing, represented by proportions in ethograms. The Kruskal-Wallis Test was used for hypothesis testing, and the Dunn Test for multiple comparisons between independent groups, with Holm-Bonferroni probability adjustment to control errors. The results indicate that vicuñas exhibit seasonal variations in their behavior, with activities such as grazing, walking, watching, and running being more pronounced during the dry season. Behavior varies according to the seasons: during the dry season, there is a greater tendency to stand, while post-rain, resting time increases. Additionally, grooming increases before the rains, and nursing is predominant afterward, revealing consistent patterns in each season. Despite seasonal variations, vicuñas show consistent behavior across different ecosystems, suggesting generalized adaptability. However, changes in behavior according to the season demonstrate their ability to adjust to different environments such as pajonales, bofedales, and tolares.
