[ECOLOG-L] reference for students on citation

[Olyssa Starry]

Dear group,
I teach in an interdisciplinary program. My students in the humanities
always ask me about the most commonly used citation style in the
sciences.
Forgive my ignorance, but is there a scientific version of the "MLA"
or "APA"? Is there a standard format agreed upon in ecology, and does
it have a name?
Thanks,
Olyssa
