Bumble bee occurrence data used for "Climate change winners and losers among North American bumble bees": These data comprise 649 407 specimen records from 48 species and spans 1805–2020. These records have been compiled from a variety of collections and sources with reputable origin. Data contributors are listed in: https://www.leifrichardson.org/bbna.html

Data Curator: Leif Richardson

In order to produce the book's maps maps, graphs of seasonal activity patterns and lists of host plants, we gathered digital records of bumble bee specimens from museums, academic collections, private collectors, and online specimen data repositories. We also received some larger, aggregate datasets from individuals who had collected bee data for other purposes. The database included nearly 275,000 records of bumble bee specimens collected around North America from 1805 to the present. I continue to add to the database in order to use it for additional research and conservation projects, and as of April, 2019, have more than 587,000 specimen and observation records for North American bumble bees. This effort has benefited from contributions by nearly 250 individuals and/or institutions around the world. Below is a list of individuals and institutions whom I gratefully acknowledge as direct contributors to this resource and to publications that are based on it. A full list of collections in which the specimens reside is available upon request.
