First record of nectar feeding by the exotic lizard Lepidodactylus lugubris (Duméril & Bibron, 1836) in urban environments in Brazil with notes on unusual feeding behaviors

Abstract

Interactions between reptiles and plants are less studied than those involving other vertebrate groups, especially in urban environments, which may limit our understanding of the ecological roles of reptiles such as lizards. In this study, we report for the first time a nectarivorous interaction between Lepidodactylus lugubris, a parthenogenetic lizard of the family Gekkonidae, and a plant species in an urban environment in Brazil. We also summarize the existing literature on visually documented nectarivorous behavior for this species in urban environments. The animal was observed feeding on flower nectar during the day in a building. This behavior demonstrates the species' dietary plasticity and highlights that important ecological interactions can occur even in urban environments. In a broad sense, the relationship between lizards and plants has been underestimated, but recent studies indicate that some species may act as occasional pollinators, contributing to the maintenance of local flora. The presence of this gecko in urban areas also underscores the need to better understand the ecological functions performed by reptiles and their resilience in modified habitats. New records and studies on this interaction may help elucidate the ecology of L. lugubris and its potential role in pollination.
