I have noticed in my few years on iNaturalist that the observation maps of a given taxon frequently show a much wider geographic range than that described in the few published papers on that taxon. This clearly is not just my impression; I just scrolled through all three wikis:
Published papers that use iNaturalist data - wiki 1 (up to 2019)
Published papers that use iNaturalist data - wiki 2 (2020 and 2021)
Published papers that use iNaturalist data - wiki 3 (2022 and 2023)
…and one of the things that really stood out to me was that a high percentage of the papers – possibly even more than half – were specifically about expanding known ranges based on iNat observations. Many were explicitly titled “First record of such-and-such taxon in such-and-such place.”
What I am hoping for, though, is a paper that does not merely do this, but is specifically about this phenomenon. That is, if I was writing a paper of my own, and I wanted to state, “The iNaturalist citizen science platform often has more up-to-date range data than published studies,” is there a source I could cite for that statement? The thread, Literature specifically evaluating the usefulness of iNat data in science? does not seem to address that specific question.
