Need help with a mysterious scientific journal

[PhDP]

I really need an article in a scientific journal. In fact, I've access to "all" the volumes of this journal for its start, "Evolutionary Ecology", but some numbers are missing.

 

Evolutionary Ecology, 1989, Volume 3, Number 2 and 3 are missing from the electronic version (on SpringerLinks). Also, I've looked at the library of my university and of all the biggest universities in my province (even McGill), those 2 number are always missing, I've even contacted the author of the article, and he don't have it.
