We just published a paper showing pollinators experienced higher levels of reproductive success in isolated trees at a fig species’ expanding range margin, in spite of there being lower numbers of pollinators in these isolated trees (half as many) as there were in larger populations of fig trees. This increase in reproductive success was partly a consequence of parasitoid release (Mackay KD, Gross CL, Ryder DS., Increased reproductive success through parasitoid release at a range margin: Implications for range shifts induced by climate change. J Biogeogr. 2020;00:1–15. https://doi.org/10.1111/jbi.13795).
