Abstract

Fragmentation of forest habitats can have a negative impact on the diversity of many species. When fragmentation impacts pollination, it can result in major changes to the composition of forest plant communities as well as a reduction in fruit production for nearby agriculture. I studied Hymenoptera diversity in a four hectare fragment and a continuous forest using Euglossine traps as well as a mixture of honey and water to attract Hymenoptera species. Hymenoptera diversity did not differ significantly between the two habitats but abundance of Hymenoptera, Euglossine, and Apidae were all significantly greater in the continuous forest site. This indicates that continuous forest supports a larger, more stable population of Hymenoptera species, thereby supplying steadier pollination services to the forest and nearby farms. La fragmentación de los hábitats forestales puede tener un impacto negativo en la diversidad de muchas especies. Cuando la fragmentación impacta los procesos como la polinización, puede causar cambios grandes de la composición de especies de plantas en las comunidades del bosque. Además podría ocasionar una reducción en la producción de frutos en los cultivos aledaños. Estudie la diversidad de Hymenoptera en un fragmento de cuatro hectáreas de bosque continuo usando trampas de Euglossines, además de una mezcla de miel y agua para atraer a las especies de Hymenoptera.
