Introduced and invasive species are fundamentally altering the structure of ecological communities (Elton 1958; Gallardo et al. 2015; O’Dowd et al. 2003), leading to increased species extinctions and biodiversity loss (Bellard et al. 2016; Capinha et al. 2015). In addition to shifting community composition, exotic species can impact ecosystem functioning by altering the growth and fitness of primary producers and become costly agricultural pests (Cameron et al. 2016; Paini et al. 2016). However, the impacts of exotic species may be more nuanced when they engage in keystone mutualisms like pollination. In these cases, there is potential for direct negative impacts through competition with native species for shared resources (Mallinger et al. 2017; Thomson and Page 2020) but also potential to benefit other species through interactions that increase primary productivity (Vilà et al. 2011) and plant reproduction (Hanna et al. 2013). Indeed, recent meta-analyses of the invasive species literature largely ignore exotic mutualists (Mollot et al. 2017) and we are only beginning to understand the impacts of invasive species on mutualistic interactions (Geslin et al. 2017; Valdovinos et al. 2018).
