Potential seed dispersal of cumbaru (Dipteryx alata) by fruit-eating bats (Artibeus sp.) in a Brazilian urban context

Abstract

The rapid increase of urbanization across the tropics has transformed natural landscapes into intensely modified environments, challenging native species to thrive in human-dominated spaces. Frugivorous bats perform vital ecological roles in urban landscapes, preventing the further decline of seed dispersal dynamics. The “cumbaru” tree Dipteryx alata – a large native species widely distributed throughout Cerrado savannahs of South America – serves as an important food resource for wildlife. In this study, we documented and quantified the cumbaru potential dispersal performed by Artibeus sp. in an urban area located in the limits between Cerrado and Pantanal (Cáceres municipality, Mato Grosso, Brazil). Our results revealed that, during 21 nights of observation, individuals of Artibeus sp. transported 27 fruits at a distance of approximately 35 m. Our observations on the dynamics of seed dispersal by bats in an urban context provide preliminary, but important, insights for management actions to ensure the maintaining of species interactions and biodiversity conservation across human-dominated landscapes.
