Acknowledgements:
We thank C. Couchoux for advice on the genotyping work, S. Ikonen for
rearing the insects, and S. Ojanen and many students from the University
of Helsinki, who conducted the annual survey and collected the samples
over the years. We are grateful to I. Hanski and P. Seppä for their
interest in and constructive discussions on the study. This work was
supported by the Academy of Finland (grant #266021 to AD, and #255553
to SvN). Diversity, Equality and Inclusion statement: The
authors highly value equity, diversity and inclusion in science. We
acknowledge the international character of our team, which significantly
contributed to the completion and quality of the study. It includes
researchers from different countries, backgrounds and career stages.
Authors are from France, India, Hungary and USA. Three co-authors are
female and one is male. We cite a large body of studies from a
potentially male-biased author-list. We wish to address these DEI
shortcomings in future work.
