These 2 species look very similar. Charles rives states originated by Drs. Long and Evans in 1915 by crossing several Wistar Institute white females with a wild gray male. To Charles River from Canadian Breeding Farm and Laboratories in 1978.
and
These rats have taken their name from the Lister Institute, where the stock first originated. From Glaxo to Charles River Laboratories UK in 1990 and again in 1996. To Charles River Germany in 2007.
Has anyone ever compared the behavior?
Look e.g. here:

They are the same species, since they are both Rattus norvegicus.
There are are some papers that discuss the differences. For example: http://www.ncbi.nlm.nih.gov/pubmed/8806027
Thank-you to Ulrich. Very interesting paper by van Goethem. Figure 4 does show some difference between Lister and Long-Evans in with regard to the Memory impairing effects of scopolamine although I would have liked to see the exact same doses on the x-axis. However they are much more similare to each other than they are to Wistars. As Robin said, they are the same species but they are listed as a different rat by charles river and over the years, I have learned that subtle things can matter which is why I asked the question. This would be a very expensive test to do in Canada as I belive the Lister rat is only available in Europe and then you have to account for the stress difference in shipping. Thank-you again
