Video length: 6:25 min.
Selected for the CLEAN Collection.
This video addresses the impact of climate change on several butterfly populations. Warming temperatures lead to shifts in location of populations of butterflies or die-offs of populations unable to adapt to changing conditions or shift to new locations.
Following suggestions are by CLEAN reviewers:
This video may be used as a good way to introduce the linkages between biological adaptation and evolution and climate change to students.

About the Science
Butterflies are very good indicators of the health of the ecosystem they are in.
If habitat is degrading, butterflies will show the impacts first.
Over the last 30 years, shifts have occurred where butterflies live.
Their areas of residency are shifting - whole populations go extinct while other areas regain populations.
The average location of a population today is about 100 miles further north of where is used to be.
Passed initial science review - expert science review pending.
About the Pedagogy
The video is treated as a standalone: a lesson plan is available with it in the Windows to the Universe site ( http://www.windows2universe.org/earth/changing_planet?adaptation_species_intro.html ).
Assessment is at the discretion of the educator and how this resource is applied.
