Reference formated with "and" between all authors - not what I want

hanks for the quick response.

The output is currently set for Ecology (Ecology.ens - comes with Endnote X6), but I tried other outputs with the same results.  I also have other references with more than two authors in the same document, and they are formated correctly.  I feel like there is an extra space or aa missing comma or something like that, but I can’t figure it out.
