Description
Summary:The reproductive pattern of three fruit-eating bats, Glossophaga soricina, Artibeus jamaicensis, and Artibeus lituratus, was studied in the "Costa Grande" region of Guerrero, Mexico, from June 1977 through May 1978. Reproductive state of females (pregnant or lactating) and growth of mammae were recorded to establish the reproductive pattern for each species. Lactating G. soricina were captured only in November, whereas the other two species appeared to have two periods of reproduction each year: A. jamaicensis with one peak in March and another in August, and A. lituratus in April and July. Whereas the reproductive activity of G. soricina coincided with the abundance of "zazanil" (Cordia dentata) fruits, that of A. jamaicensis and A. lituratus coincided with the abundance of almendro fruits (Terminalia catappa) and capulin fruits (Muntingia calabura). /// Se estudiaron los patrones reproductivos de los murciélagos frugívoros Glossophaga soricina, Artibeus jamaicensis y Artibeus lituratus en la Costa Grande de Guerrero, México desde junio de 1977 hasta mayo de 1978. Con base en los estados de preñez, lactancia y desarrollo mamario, se establecieron patrones reproductivos para cada especie. Se observó que Glossophaga soricina presenta un sólo período de lactancia en noviembre, mientras que las dos especies del género Artibeus tienen dos: A. jamaicensis en marzo y en agosto y A. lituratus en abril y julio. Mientras que las actividades reproductivas de G. soricina coinciden con la abundancia de frutos de "zazanil" (Cordia dentata), en las otras dos especies con la presencia de los frutos del "almendro" (Terminalia catappa) y del "capulín" (Muntingia calabura).
