“…Given that interactions disappear faster than species themselves (Janzen, 1971 ), if the goal of restoration is to conserve species and ecosystem functions in the long term (Brudvig, 2011 ; Clewell & Aronson, 2012 ; Traveset & Richardson, 2020 ), it is necessary to ensure the maintenance of the structure of ecological networks to guarantee the persistence of entire communities. Our results add to previous studies highlighting that network structure can be used as a proxy not only for the provisioning of ecosystem services (Kaiser‐Bunbury et al, 2017 ; Traveset & Richardson, 2020 ), but also in restoration studies to assess the impact of restoration practices on population dynamics (Gaiarsa et al, 2021 ; Tylianakis et al, 2010 ).…”

“…The ultimate success of restoration strategies is the persistence of wild populations (Miller et al, 2017 ), but there are only a handful of studies connecting populations to restoration practices (e.g., Gaiarsa et al, 2021 ; Rodewald et al, 2015 ). For restoration to be successful, it is necessary to assess not only how ecosystem functions, such as pollination, are impacted by restoration practices (Cariveau et al, 2020 ; Kaiser‐Bunbury et al, 2017 ; Miller et al, 2017 ), but also how the remaining species are affected in the time following restoration.…”

Past and recent studies have focused on the effects of global change drivers such as species invasions on species extinction. However, as we enter the United Nations Decade of Ecosystem Restoration the aim must switch to understanding how invasive‐species management affects the persistence of the remaining species in a community. Focusing on plant‐pollinator interactions, we test how species persistence is affected by restoration via the removal of invasive plant species. Restoration had a clear positive effect on plant persistence, whereas there was no difference between across treatments for pollinator persistence in the early season, but a clear effect in late season, with higher persistence in unrestored sites. Network structure affected only pollinator persistence, while centrality had a strong positive effect on both plants and pollinators. Our results suggest a hidden effect of invasive plants—although they may compete with native plant species, invasive plants may provide important resources for pollinators, at least in the short term.

Mutualistic coevolution and community diversity favour persistence in metacommunities under environmental changes

Linking local to regional ecological and evolutionary processes is key to understand the response of Earth's biodiversity to environmental changes. Here we integrate evolution and mutualistic coevolution in a model of metacommunity dynamics and use numerical simulations to understand how coevolution can shape species distribution and persistence in landscapes varying in space and time. Our simulations show that coevolution and species richness can synergistically shape distribution patterns by increasing colonization and reducing extinction of populations in metacommunities. Although conflicting selective pressures emerging from mutualisms may increase mismatches with the local environment and the rate of local extinctions, coevolution increases trait matching among mutualists at the landscape scale, counteracting local maladaptation and favouring colonization and range expansions. Our results show that by facilitating colonization, coevolution can also buffer the effects of environmental changes, preventing species extinctions and the collapse of metacommunities. Our findings reveal the mechanisms whereby coevolution can favour persistence under environmental changes and highlight that these positive effects are greater in more diverse systems that retain landscape connectivity.

“…These species are highly generalized in the communities they invade and suppress native pollinator activity due to exploitative competition [57][58][59][60][61][62][63][64] . In terms of colonizers' niche flexibility enabled by adaptive foraging, empirical literature shows that pollinator species with high niche flexibility are highly successful colonizers and occupy predictable motif positions 65 .…”

Understanding the assembly of plant-pollinator communities has become critical to their conservation given the rise of species invasions, extirpations, and species’ range shifts. Dynamic network analyses can advance such understanding by elucidating the effects of species’ direct and indirect interactions on network assembly. We investigate the role of intra-guild indirect interactions on assembling plant-pollinator networks by developing: 1) an assembly model that includes population dynamics and adaptive foraging, and 2) a motif analysis tracking the effects of colonizing species throughout assembly. Motifs — networks’ building blocks — allow an in-depth analysis of indirect interactions. We found that adaptive foraging reduces the otherwise strong effect of indirect competition for shared mutualistic resources on community assembly. This allows for coexistence between specialist and generalist species within the same guild and the emergence of nested networks. Further, by maintaining the persistence of specialist species, who are most vulnerable to competitive exclusion, adaptive foraging allows for the development of richer and less connected networks which is consistent with empirical pollination networks. Our work contributes new understanding and methods to study the effects of species’ indirect interactions on community assembly.
