“…The majority of studies addressing plant-pollinator mutualisms between invasive plants and native insects have focused on indirect impacts of plant invasion for native plant pollination at the scale of communities, while few studies have examined direct effects of invasive plants on native flower visitor individuals or populations (Stubbs et al 2007, Stout andTiedeken 2017).

Novel plant–insect interactions in an urban environment: enemies, protectors, and pollinators of invasive knotweeds

Relationships between invasive plants and other species in their introduced ranges may facilitate or hinder the process of invasion. Fallopia japonica (Japanese knotweed), Fallopia sachalinensis (giant knotweed), and their hybrid Fallopia 9 bohemica (Bohemian knotweed) are widespread invasive plants in North America and Europe. These species possess extrafloral nectaries (EFNs) that attract mutualist insect protectors in their native ranges. Popillia japonica Newman, 1841 (Japanese beetle) is a primary herbivore of invasive Fallopia spp. in these species' native range in Japan. These natural enemies are reunited in North America, where Fallopia spp. have been repeatedly introduced as ornamental plantings of residential and commercial properties since the 1800s, and the Japanese beetle has become a widespread insect pest. Spread of Fallopia spp. and their hybrids along linear features of urban landscapes such as roads, railways, and waterways make their performance in urban environments important to these invasive species' impact. To test the role of insect interactions in the success of Fallopia japonica and F. 9 bohemica in urban conditions in their invasive range, we examined ant visitation, Japanese beetle abundance and herbivory, ant-Japanese beetle interactions, pollinator visits, and seed production. All active herbivory observed was by Japanese beetles. Leaf area loss to herbivory was much lower than levels reported in Japan, suggesting partial enemy release. New Fallopia leaves were more frequently visited by ants than mature leaves, while Japanese beetle herbivory was observed on mature but not on new leaves. All ant species observed visiting invasive Fallopia EFN were native to North America. Active physical defense by these ants against Japanese beetles was observed but was rare. Native and non-native insects visited Fallopia flowers, followed by seed production. Our results indicate that both native and non-native species may facilitate invasion of Fallopia through pollination and protection mutualisms.

“…Finally, the spread of new plant species can modify pollinator–flower interaction networks through different plant traits, including floral resource quantity and quality, spatial and temporal availability, and accessibility (Ghazoul , Nienhuis et al. , Stout and Tiedeken ). The impacts of invasive plants can occur at the individual and population levels, including decreasing interspecific competition among pollinators (Fontaine et al.…”

“…Moreover, these impacts are species‐dependent as different plant species can impact pollinators in different ways and pollinators do not all respond uniformly to new plant species (Tiedeken et al. , Stout and Tiedeken ). Invasive plants could therefore impact pollinators at individual (i.e., nutrition, health, and fitness) and population levels in terms of size, density, and growth rates, but also population genetic diversity and structure (e.g., heterozygosity; Lenda et al.…”

Bumble bee parasite prevalence but not genetic diversity impacted by the invasive plantImpatiens glandulifera

et al. 2019

While many bee species are experiencing population declines, some host plant generalist bees remain common in Europe, partly because they seem able to shift to new resources. However, foraging on a new alternative plant, such as an invasive species, can modify diet quality and have a potentially detrimental effect on bee health. Herein, we investigated whether the spread of the invasive plant Impatiens glandulifera affects Bombus pascuorum population regarding parasite prevalence, genetic structure, and nest density in Belgium. While no difference in bumble bee genetic structure was detected between invaded and uninvaded sites, we show that I. glandulifera occurrence was significantly correlated with a decrease in the prevalence of Apicystis bombi but not the prevalence of three other parasite species (i.e., Crithidia bombi, Nosema bombi, Nosema ceranae, and Nosema sp.). Regarding our investigations, this effect was likely not due to variation in local bumble bee population fitness before I. glandulifera flowering, nor to the relative abundance of other pollinators such as Apis mellifera, but the unique chemical composition (i.e., polyphenol rich) of the pollen of I. glandulifera remained as an interesting hypothesis. Whereas B. pascuorum queens probably colonize all the potential nesting sites in an area, invaded by I. glandulifera or not, the abundance of polyphenol ampelopsin in pollen from I. glandulifera pollen might reduce local parasite prevalence. Our field study confirms that bumble bee parasite prevalence is potentially related to the particular chemical composition of collected pollen. Plant traits such as secondary metabolite occurrence could play a key role in the health and conservation of bumble bees.

Animal pollinators have driven the diversification of plants on the earth for more than 100 million years. The mutualism between plants and their pollinators rests on an exchange: food for pollinators and efficient vectoring of sexual reproduction for plants. This relationship has been shaped by many factors during the course of evolution. Competition between pollinators for access to nectar and pollen, and among flowering plants for the attention of pollinators, has influenced the shape, colour and scent of flowers and the extent to which plants invest in the production of pollen and nectar. While many pollinators are 'generalists' and visit a variety of flowering plants to obtain food, close relationships between specific pollinators and plant species have developed throughout the course of evolutionary history. An important issue today, given the widespread concern about wild and managed pollinators, is determining how human activities impact the varied relationships between plants and their insect pollinators.Insect pollinator declines are being attributed to interactions between multiple stressors including pesticides, pathogens and pests, but there is a general consensus that diminishing forage is of overarching importance (Potts et al. 2010; Vanbergen & the Insect Pollinators Initiative 2013;Goulson et al. 2015). In other words, the single most pressing issue facing plants and their pollinators is the preservation of habitat. Loss of natural habitat reduces plant diversity and abundance which directly translates into fewer and less diverse sources of forage for pollinators (Potts et al. 2003;Senapathi et al. 2015;Baude et al. 2016). Generalist bee species require diverse sources of floral pollen because pollen varies in digestibility and nutritional content and may lack essential nutrients (Roulston & Cane 2000). In addition, an environment that is plant species rich is more likely to have floral resources available to pollinators over longer periods, important for social species with long-lived colonies (Wray & Elle 2015). For pollinators that have specialised relationships with flowering plants like certain solitary bee species (Muller & Kuhlmann 2008), reduction in habitat often translates into critical reduction or elimination of their specialist plant partner populations. However, loss of natural habitat also impacts pollinators through reductions in nesting sites and in fewer host plants for larvae (as in the case of Lepidoptera). Thus, it is easy to predict that solely through the reduction of food and nesting sites, pollinator populations will decline. The collection of eight papers in this special feature highlights the factors that govern the evolution of plant-pollinator relationships and the characteristics of pollinators and plants that make them resilient to anthropogenic change.In the opening review, Deepa Senapathi and colleagues examine the evidence for landscape impacts on pollinator communities in northern temperate systems (Senapathi et al. 2017). They deal with assessment methods, th...
