Title: Diagnóstico de los murciélagos frugívoros como dispersores de semillas en Zamorano
Abstract: Frugivorous bats through quiropterocoria disperse seeds to long distances which benefit to the landscape where they live. A diagnosis of the diversity of frugivorous bats at Zamorano was realized. It also identified the seeds consumed and determined most important bat species as seed dispersers. Four areas of study were defined: area one formed by the oxidation ponds one and two, area two by ponds three and four, area three by pond five and area four by Monte Redondo and Titicaca lagoons. It was sought to know if bats diet were related to their sex. A total of 210 frugivorous individuals of seven species were captured by mist nets. Seventy nine fecal samples were collected of which 5,617 seeds were extracted. The data were analyzed using the index of Margalef, Shannon H ' and Chao1. These indicated that the area three was more diverse in comparison to the others. The accumulation curve of species according to the capture effort of frugivorous bats reached on asymptote. Capture effort was 2,538 mh with a capture success of 0.08 individual/mh. Twelve morphospecies were identified with greater abundance of Ficus spp. and Piper spp. A positive correlation was found between the sex and the number of dispersed seed. The highest Disperser Importance Index (DII) was determined for Artibeus jamaicensis (3.9); the most important agent dispersing ten out of 12 morphospecies identified.
