This Zotero citation style attempts to copy the apalike style from natbib. I created this for the ALIFE XVI, which seems to be using the same citation that MitPress uses.
The original citation style is called apalike and belongs to the Latex package natbib. I based apalike-zotero in the American Psychological Association 6th Edition available in the Zotero style repositories, and I used the Visual Editor to produce the apalike.csl file.
You need to open the Preferences (In Firefox) for Zotero, in Cite, and Add the file with the '+' button.
Or just Google how to add a citation style from file .csl in Zotero.
