Le présent document fait partie d'une série de rapports découlant de cette initiative. Ils décrivent les caractéristiques physiques, océanographiques et biologiques de l'ensemble de l'estuaire maritime et du golfe du Saint-Laurent (EMGSL) en rassemblant l'information scientifique disponible au MPO et dans la littérature afin d'identifier des zones d'importance particulière pour chacune des composantes étudiées. Il est prévu de combiner les ZIEB potentielles pour toutes les composantes et d'en faire une évaluation plus approfondie afin d'arriver à l'identification de ZIEB pour l'EMGSL.

I probably have the package French, if it came with TexLive. But I did not call it with a \usepackage, so I thought it did not intervene. I saw a mention of frenchb in the babel pdf manual, but not enough to understand if the language options used when calling babel should use french, frenchb or francais. I seem to have the same result with all 3.

But your solution of loading babel later did work:

this failed:
\usepackage[english,frenchb]{babel}
\usepackage[round]{natbib}
  \bibliographystyle{plainnat}



This succeeded:

\usepackage[round]{natbib}
  \bibliographystyle{plainnat}
\usepackage[english,frenchb]{babel}

Denis
p.s. since yesterday I installed TeXLive 2010 but it did not seem to influence this behavior.
