Reproductive phenology and floral visitors of a Langsdorffia hypogaea (Balanophoraceae) population in Brazil
چکیده انگلیسی


- We recorded ecological and morphological traits of Langsdorffia hypogeae.
- First records of the reproductive phenology and floral visitors in L. hypogeae.
- High diversity of floral visitor was observed, only sap beetles were pollinators.

The floral biology and reproductive phenology of Langsdorffia hypogaea were investigated. Flowering is annual and high synchronicity was observed along two years, with significant correlation with rainfall. The post-reproductive death of rhizomes suggests monocarpy. Flowers have anthers with extrorse dehiscence and a stigma exposed above the perigonium, and are arranged in dense inflorescences which produce extrafloral nectar. A total of 259 floral visitors were observed, mostly Hymenoptera/Formicidae (149 individuals, 17 ant species), and eight species of Araneae. Although ants were frequent floral visitors, a Coleoptera (Nitidulidae, Stelidota; 28% of total visits) species was the most abundant pollinator. In consequence of herbivory only 12.5% of all inflorescence clusters fruited, and we could not evaluate the percentage of pollinated plants due to insect damage. By being a rich resource in a season of scarcity, activity on inflorescences of L. hypogaea of both pollinators and herbivores was high.
