“…In this context, botanical gardens stand out as a good tool for the conservation of flower-visitor communities, as they serve as ecological corridors, shelter and foraging sites (Hall et al, 2017;Maruyama et al, 2019;Marín et al, 2020;Gobatto et al, 2021). Our study endorses that a botanical garden can sustain a diverse community of flower-visiting Hymenoptera in an urban environment (Ito et al, 2001;Mazzeo & Torretta, 2015;Marinho & Vivallo, 2020), being an important tool for biodiversity conservation (Hall et al, 2017;Maruyama et al, 2019;Marín et al, 2020;Gobatto et al, 2021). When it comes to botanical gardens in Atlantic Forest areas, especially in the state of Rio de Janeiro, it is clear that our results corroborate other studies already conducted, as the botanical garden studied clearly supports a diverse community of floral-visiting Hymenoptera, whose composition, which includes many pollinating species, is very similar to communities observed by other researchers (Pimentel & Rangel, 2017;Santos et al, 2017;Silva et al, 2018;Marinho e Vivallo, 2020;Gobatto et al, 2021).…”
