Author and Reviewer Pledge
It is with great sadness about the current state of scientific publishing that I make this resolve.
As of 1 January 2012, I will not submit research papers to, or review research papers for, any journal or book published by those organizations whose efforts have come to my attention either:
  • to reduce the current level of public access to the fruits of publicly funded research for their own profit or
  • to use harsh "journal bundling" contracts to extract exorbitant fees from libraries.
These organizations include: Some relevant links:




Sexually reproducing
diploid Crataegus (C. punctata)


Male-sterile, facultatively apomictic
triploid Crataegus (C. ?grandis)


Near-obligate apomictic
tetraploid Crataegus (C. chrysocarpa s.l.)


Apomictic
pentaploid Crataegus (aff. C. gaylussacia)
