ABOUT
THE PROCEEDINGS OF THE DESERT FISHES COUNCIL / SOBRE LOS PROCEDIMIENTOS DEL
CONSEJO DE LOS PECES DEL DESIERTO
It is the policy of the Council to select and publish
in the annual Proceedings of the Desert Fishes Council abstracts, discussion
summaries, business items, resolutions, and other material submitted and
presented at the Annual Symposium. All contributions are subject to editorial
review and are published following technical editing and automated electronic
processing to standardize format. Resolutions are published exactly as passed
by the membership in the business meeting of the Annual Symposium. The
Proceedings Translation Committee provides original translations of abstracts
in English when translations are not provided by authors, and edits all
Spanish abstracts provided by authors. The Translation Committee reserves the
right to edit abstracts in one language to improve grammar and clarity before
translating to the other language, but accepts full responsibility for errors
in translations for abstracts they translate. The Proceedings are published
and delivered to all members of the Desert Fishes Council and subscribing
libraries in the year following the Annual Symposium.
The Council offers extensive information on the
World Wide Web about itself and the organisms and ecosystems it
strives to protect:
