Two house mouse subspecies meet again in a hybrid zone strangely reminiscent of the Iron Curtain
- The house mouse diverged into two subspecies depending on which humans they followed.
- The Western and Eastern European house mice can interbreed, but the results are, well, mixed.
- The continent remains divided between Eastern and Western mice except for a narrow contact zone where hybrids eek out a living.
As this map of Bouguer's gravity anomaly shows, the pull of the earth varies considerably by region.
School diversity is less widespread in central and northern states
- In 2020, there will be more children of color than white children in the U.S.
- These maps indicate how racial diversity is changing the demographics of America's schools
- Diversity has massively increased, but more so in the south and on the coasts than elsewhere
Project to map global 'species richness' highlights the variety of biodiversity itself
- Biodiversity is essential for ecosystems – and humanity – to survive
- These maps show the diversity of biodiversity itself: the hotspots are all over the place
- Compounding U.S. biodiversity data produces a list of 9 'Recommended Priority Areas', most in need of protection
From a young age, Frank was fascinated by maps and atlases, and the stories they contained. Finding his birthplace on the map in the endpapers of Tolkien's Lord of the Rings only increased his interest in the mystery and message of maps.
While pursuing a career in journalism, Frank started a blog called Strange Maps, as a repository for the weird and wonderful cartography he found hidden in books, posing as everyday objects and (of course) floating around the Internet.
"Each map tells a story, but the stories told by your standard atlas for school or reference are limited and literal: they show only the most practical side of the world, its geography and its political divisions. Strange Maps aims to collect and comment on maps that do everything but that - maps that show the world from a different angle".
A remit that wide allows for a steady, varied diet of maps: Frank has been writing about strange maps since 2006, published a book on the subject in 2009 and joined Big Think in 2010. Readers send in new material daily, and he keeps bumping in to cartography that is delightfully obscure, amazingly beautiful, shockingly partisan, and more.
