I have a very strange problem with my list of figures, list of tables and bibliography which I can't figure out. There are unnecessary gaps between the lines. Any idea what could be wrong here?

The citation looks very regular to me.

hyperrefpackage last, i.e., after all other packages have been loaded. Well, there a couple of exceptions to this rule, notably for thecleverefpackage. However, all of the packages you're currently loading afterhyperrefcould be loaded earlier without causing problems. Try loadinghyperreflast (just before\hypersetup, of course) and see if that makes a difference. – Mico Jul 14 '12 at 22:32.bibentries: it kind of looks like the two problematic entries are the same 'type' of BibTeX entry. (You can if you want put it all in one file if you usefilecontents.) – jon Jul 15 '12 at 1:15.bblfile? The two entries corresponding to "Falcone" and "Florida" are needed, exactly as they appear in the.bblfile. – egreg Jul 15 '12 at 12:39
