I am considering joining the recent boycott of Elsevier, however I work with biologists on theoretical/mathematical biology (in particular, evolutionary game theory and population biology). However, It seems like [Journal of Theoretical Biology](http://www.journals.elsevier.com/journal-of-theoretical-biology/) is the premier journal for technical work in this field, and my co-authors often suggest it. 

What are some (preferably, open-access) alternatives to JTB?
