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. Full,
Contributed Papers based on works presented at the meetings are also
solicited. Authors are responsible for their own technical editing and for any
errors caused by failure to follow Instructions to Authors (published on World
Wide Web or available from the Proceedings Editor on request). All
contributions are subject to editorial review and are published following
technical editing and automated electronic processing to standardize format.
Only Contributed Papers are subject to peer review for scientific accuracy
prior to publication. Proofs of Contributed Papers, but not of abstracts, are
provided to authors for review prior to publication. 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. This committee
accepts full responsibility for errors in translations for those 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:
