Data from: Automated 24-hour surveys of flower-visiting communities reveal temporal complementarities and overlaps among strawberry pollinators

This dataset results from a study performed in the region of Paris (France) to investigate temporal complementarities and overlaps in pollinator activity periods and behaviour in different urban contexts. We carried out automated 24-hour video surveys to track strawberry flower visitors in three study sites in the region of Paris (France) with different surrounding land-use composition. We tested whether different flower visitor groups were active at different times of day (i.e. temporal complementarity vs. overlap), and whether foraging behaviour varied among groups and across the day. We found that most pollinators were active during the day, with ants reported as the main nocturnal flower visitors. Moreover, we found complementarity in the temporal activity of flower visitors in the least urbanised site. In contrast, in the more densely urbanised sites, a single peak of activity occurred during the afternoon, with dominance of honey bees, indicating overlap in temporal niche. We also found that the flower-visit duration varied substantially among pollinator groups, sites, and over the course of the day. These results emphasize how pollinator community functional complementarities can be context dependent. Indeed, currant knowledge is based mainly on diurnal observations of pollinator communities, which could bias our understanding of the relations between pollinator community composition and their contributions to pollination services. The dataset is related to the following publication: Blareau, E., Gabard, C., Riva, C., Dajoz, I. & Requier, F. (under review). Automated 24-hour surveys of flower-visiting communities reveal temporal complementarities and overlaps among strawberry pollinators. Global Ecology and Conservation. Two datasets are available: The abundance of each Morphotype of insect (i.e. honey bees (Apis mellifera), bumble bees (genus Bombus), small wild bees (i.e. body length shorter than 1cm), large wild bees (i.e. body length longer than 1cm), hoverflies (flies from the Syrphidea family), non-hoverfly Diptera, butterflies (diurnal Lepidoptera), moths (nocturnal Lepidoptera), beetles (Coleoptera) and ants (family Formicidae), in each of the three sites (i.e. Suburban garden, Urban park or Urban rooftop) for each hour of recorded footage. This data is available in the file "Visits.csv", with the corresponding metadata in the file "Visits_meta.csv". Foraging behaviour of each insect seen visiting a flower. For each insect visit, this data informs the part of the flower visited (i.e. the reproductive parts of the flower such as pistils and stamens, or non-reproductive parts such as sepals and petals), and the duration of the flower visit (from the first contact with either reproductive or non-reproductive parts of the flower to the moment the insect left the flower), in each site and over the course of the day and night. This data is available in the file "Behaviour.csv", with the corresponding metadata in the file "Behaviour_meta.csv".
