Tom,

Field herping? What a concept for science. Consider the following man...

http://www.sfrestore.org/wg/wgminutes/2009meetings/15,16jul2009/Invasive_Exotic_Animals_Submissions.pdf

Invasive Exotic Animals-4, Joint WG/SCG Meeting, July 15, 2009, U.S. Fish and Wildlife Service Actions.

1. Constrictor Snake Risk Assessment.

"...The work, which is being completed by the U.S. Geologic Survey (USGS), will: 1) conduct comprehensive literature reviews to compile available information for each species individually...2) delineate localities that have climate similar to the native-range specimen records and available climate data from sources such as the World Climate online database, 3) use published habitat information to estimate which U.S. habitats are potentially inhabitable by each species..."

There's LOTS of field work in that USGS "Assessment"...

Looks like Pyron read something else...I guess he didn't have access to the World Climate online database or the IPCC Climate Change information at Fort Collins...
