Data from: Pollinator dependence but no pollen limitation for eight plants occurring north of the Arctic Circle

Intact interactions between plants and pollinators are essential for the
reproduction of pollinator-dependent plant species. Global change factors,
such as climate change, have the potential to disrupt these interactions
and subsequently impair pollination service. This disruption can result in
insufficient pollen receipt for plants and lower their reproduction
success. High latitude sites experience particularly rapid climate change
and plants at these locations are expected to be vulnerable to lower
reproductive success due to pollen limitation. Pollen supplementation
experiments, which assess the degree to which plant reproduction is pollen
limited, have been conducted across the globe but are rare in high
latitude regions. To fill this knowledge gap, we experimentally
investigated the pollinator dependence and magnitude of pollen limitation
in eight plant species north the Arctic Circle in Lapland, Finland. Our
findings show that all plant species were pollinator dependent, but not
pollen limited. We discuss several mechanisms that might buffer our focal
plants from pollen limitation. Our results demonstrate that many plant
species north of the Arctic Circle are currently receiving adequate
pollinator service and provide a baseline for future comparisons of
pollinator dependence and pollen limitation in the Arctic across species
and time.
