“…In any case, the manipulation of behavioural traits of pollinators is just one facet of the multi-faceted interactions mediated by floral nectar, which should therefore be considered from a more comprehensive perspective. The role of microorganisms, yeasts, and bacteria in these multifaceted interactions seems largely overlooked [ 174 , 186 , 187 ], limiting an overall understanding of their role in pollinator behaviour, plant-pollinator interactions, and plant fitness.…”

In recent years, our understanding of the complex chemistry of floral nectar and its ecological implications for plant-pollinator relationships has certainly increased. Nectar is no longer considered merely a reward for pollinators but rather a plant interface for complex interactions with insects and other organisms. A particular class of compounds, i.e., nectar secondary compounds (NSCs), has contributed to this new perspective, framing nectar in a more comprehensive ecological context. The aim of this review is to draft an overview of our current knowledge of NSCs, including emerging aspects such as non-protein amino acids and biogenic amines, whose presence in nectar was highlighted quite recently. After considering the implications of the different classes of NSCs in the pollination scenario, we discuss hypotheses regarding the evolution of such complex nectar profiles and provide cues for future research on plant-pollinator relationships.

“…In pollination ecology, the high mobility and movement range of flying insects is a key factor to understand the dispersal abilities of the floral microbiota ( Vannette and Fukami, 2017 ; Morris et al, 2019 ; Vannette, 2020 ). Pollinator foraging include repeated visitations of flowers by several different insects species, so that flowers can serve as hubs for microbial exchange within plant pollinator networks ( Francis et al, 2021 ; Keller et al, 2021 ; Zemenick et al, 2021 ). Microbes can even directly influence pollinator behavior and preferences, altering floral visitation and nectar removal rates ( Schaeffer et al, 2017 ; Rering et al, 2020 ; Jacquemyn et al, 2021 ).…”

“…But flying insects do not necessarily cover larger absolute geographic distances than terrestrial animals, but mobility per se with a high frequency of movements within a smaller range could expose a host to heterogeneous microenvironments. This is particularly important for microbe–plant–pollinator interactions, since the dispersal of nectar microbes is directly linked to the foraging behavior of pollinators ( Cullen et al, 2021 ; Francis et al, 2021 ). Wild bee species vary in their foraging ranges from a few hundred meters to several kilometers, while nocturnal moth can easily exceed movement ranges to several hundred kilometers ( Greenleaf et al, 2007 ; Satterfield et al, 2020 ).…”

The gut microbiota of animals displays a high degree of plasticity with respect to environmental or dietary adaptations and is shaped by factors like social interactions, diet diversity or the local environment. But the contribution of these drivers varies across host taxa and our ability to explain microbiome variability within wild populations remains limited. Terrestrial animals have divergent mobility ranges and can either crawl, walk or fly, from a couple of centimeters toward thousands of kilometers. Animal movement has been little regarded in host microbiota frameworks, though it can directly influence major drivers of the host microbiota: (1) Aggregation movement can enhance social transmissions, (2) foraging movement can extend range of diet diversity, and (3) dispersal movement determines the local environment of a host. Here, I would like to outline how movement behaviors of different host taxa matter for microbial acquisition across mammals, birds as well as insects. Host movement can have contrasting effects and either reduce or enlarge spatial scale. Increased dispersal movement could dissolve local effects of sampling location, while aggregation could enhance inter-host transmissions and uniformity among social groups. Host movement can also extend the boundaries of microbial dispersal limitations and connect habitat patches across plant-pollinator networks, while the microbiota of wild populations could converge toward a uniform pattern when mobility is interrupted in captivity or laboratory settings. Hence, the implementation of host movement would be a valuable addition to the metacommunity concept, to comprehend microbial dispersal within and across trophic levels.

“…When cognition mediates species interactions, cognitive impairments may also have community-level effects. For example, infection-impaired learning by pollinators could impact plant reproduction and the composition of floral microbial communities [64]; likewise, disruption to the cognitive performance of either parasitoids or their hosts [65] could benefit the opposite party.…”
