Question marks in bibliography entries

Some publications have a title which ends in a question mark (a.k.a. interrogation mark or interrogation point). This becomes a problem when typesetting a bibliography, since a full stop is added after the title, resulting in something like:

Livermore, R., Hillenbrand, C.-D., Meredith, M. and Eagles, G. (2007). Drake Passage and Cenozoic climate: An open and shut case?. Geochemistry, Geophysics, Geosystems, 8(1), Q01005.

Note the ugly ‘?.’ conjunction at the end of the title.
