It is difficult to summarize everything contained in this paper but the abstract is as follows (there is much more hidden away in the paper, I promise, especially the supplement): </div><div class=""><br class=""></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">Insects are the focus of many recent studies suggesting population declines, but even<br class="">invaluable pollination service providers such as bees lack a modern distributional<br class="">synthesis. Here, we combine a uniquely-comprehensive checklist of bee species<br class="">distributions and >5,800,000 public bee occurrence records to describe global patterns<br class="">of bee biodiversity. Publicly-accessible records are sparse, especially from developing<br class="">countries, and are frequently inaccurate throughout much of the world, consequently<br class="">suggesting different biodiversity patterns from checklist data. Global analyses reveal<br class="">hotspots of species richness, together generating a rare bimodal latitudinal richness<br class="">gradient, and further analyses suggest that xeric areas, solar radiation, and non-forest<br class="">plant productivity are among the most important global drivers of bee biodiversity.<br class="">Together, our results provide a new baseline and best practices for studies on bees<br class="">and other understudied invertebrates.</blockquote><div class=""><br class=""></div><div class="">I hope you all enjoy the paper and that it might prove useful for your work. If you have any queries, I am happy to chat further on this subject. This is just a first step and there's much more we can do to improve these models and we definitely want to use higher-resolution in the future. More yet to come! </div><div class=""><br class=""></div><div class=""><br class=""></div><div class="">-Michael</div><div class=""><font class=""><br class=""></font></div><div class=""><font class=""><br class=""></font></div><div class=""><font class="">PS I'm also including PDFs of two taxonomy-centric articles I've put out with collaborators in the last year.
