Abstract

Nectivorous bats play important roles in pollination systems in the tropics, by transferring pollen carried on their bodies between the plants that they visit for nectar. The purpose of this study was to evaluate diversity indices of pollen loads found on individuals of Hylonycteris underwoodi (Glossophaginae). It was conducted in the Selvatura Adventure Park in Monteverde, Costa Rica during the rainy season, and related pollen load diversity to aspect ratio, wing tip index, and mass of individuals (N = 30 males). The pollen load on individuals had low richness (2.20 ± 0.81), diversity (0.09 ± 0.16), and evenness (0.09 ± 0.15) due to the large abundance of Markea sp. pollen grains. Markea sp. was present on every individual, suggesting a specialization by H. underwoodi. Neither the variation of the overall pollen load nor the variation in the abundance of Markea sp. pollen grains could be explained by aspect ratio, wing tip index, or mass of the individuals. Los murciélagos nectarívoros juegan un papel importante en los sistemas de polinización en las zonas tropicales, transfiriendo el polen llevado en sus cuerpos entre las plantas de néctar que visitan. El propósito de este estudio fue evaluar los índices de diversidad de cargas de polen que se encuentran en los individuos de Hylonycteris underwoodi (Glossophaginae). Este estudio se llevó a cabo en Selvatura, Monteverde, Costa Rica durante la estación lluviosa.
