Estudo do uso de Combretum lanceolatum ex Eichler como recurso alimentar para avifauna na base avançada de pesquisa do Pantanal em Poconé-MT

Abstract

Among the vast diversity of plants that occur in the Pantanal, the Combretum lanceolatum Pohle x Eichler 1935, popularly known as "pombeiro", belongs to the Combretaceae family and the Combretum genus. However, recent studies show that the gelatinous nectar of unique chemical composition may be being used as a food resource for birds. Given the said information, this study identified and characterized, the ecological interrelations of avifauna with Combretum lanceolatum, in addition to establishing the richness and diversity of the avifauna observed in contact with the "pombeiro" and their respective diets during the flowering period (June 2022). The data were collected at the Pantanal Advanced Research Base, through active observation in three sampling units of 20 meters with 50 meters between units. Among the results, it was possible to observe 87 species of 17 different families interacting with the "Pombeiro", however these species are mostly insectivorous which indicates a greater complexity of ecological relationships, indicating that this species plays an important ecological role, and it is necessary an adequate management of these plants.
