Posted by: Tom Lott at Sun Apr 22 13:06:36 2007 [ Email Message ] [ Show All Posts by Tom Lott ] I am sure most here are familiar with this range map (below) from Werler and Dixon (2000). It has always impressed me how this map speaks volumes for the importance of roadways in obtaining voucher specimens. Considering that each and every dot on this map represents a specimen in a museum somewhere (Werler and Dixon’s requirements), it is remarkable how the dots literally trace out the roadways in Trans-Pecos Texas. Just from a rough estimate, I would guess that >90% of these records come from roadways. | ||
