Estructura social y composición temporal en una colonia de Nyctinomops laticaudatus (Chiroptera: Molossidae) Social structure and temporal composition in a colony of Nyctinomops laticaudatus (Chiroptera: Molossidae)

Abstract

Poco se conoce acerca de la estructura social de los molósidos en el Neotrópico. En este estudio se observó durante 4 periodos (2006/2007) la distribución espacial y la variación temporal de una colonia de Nyctinomops laticaudatus en el Palacio del Gobernador de la zona arqueológica de Uxmal en Yucatán. Se observaron 66 cavidades ocupadas por grupos mixtos de estos animales. Los grupos mixtos se conservaron todo el año, pero los individuos cambiaron de sitio de percha y de asociación de un grupo a otro. Esta estructura sugiere una organización promiscua. Durante los 2 años de observación sólo se identificaron adultos dentro de las cavidades, mientras que los juveniles y recién nacidos perchaban fuera de éstas. Los periodos de descanso fueron los más comunes en la colonia, pero también se observaron cópulas y visitas de individuos en los sitios de percha. Estos grupos de N. laticaudatus se caracterizan por un bajo grado de cohesividad entre sus diferentes miembros.Little is known about the social structure of the molossid bats in the Neotropics. During 4 observational periods (2006/2007), we studied the spatial distribution and temporal variation of a colony of Nyctinomops laticaudatus inside the Governor's Palace at the Archeological Zone of Uxmal, Yucatán, Mexico. We surveyed 66 roosting cavities consisting of mixed groups of males and females. This particular association (mixed groups) occurred throughout the study, but bats shifted group membership by moving continuously from one group to another. Because of this pattern, we were unable to describe a unique social structure and we proposed a promiscuous system for the species. During the 2 year study, we identified only adult bats inside cavities, while newborns were observed roosting outside cavities in adjacent walls. Resting was the most common activity inside cavities, but visits and copulations were also recorded. In groups of Nyctinomops laticaudatus both sexes are presented and differ with other bats due to their lower degree of cohesiveness.
