[Coral-List] Genomic determinants of coral heat tolerance across latitudes

[Douglas Fenner]

Sorry, I didn't figure out how to find the author's email yesterday for
this article.  The way to do it is to go to the Science website (
www.sciencemag.org) then click on the current issue.  Then find the
article, and click on "abstract" which is open-access.  There you see all
the authors, and it gives the corresponding author (Line K. Bay)'s email:
