This looks like bug 1511590 (PDF export omits opacity inherited from parent) http://sourceforge.net/tracker/index.php?func=detail&aid=1511590&gro...
I've got a fix for this in SVN, but it has showed negative side-effects in Bulia's tests.. (it doesn't work at all for him) Feel free to give it a try. Your image exports fine for me.
- the colors seem to be slightly off (too brownish with regards to the
original). Don't know if this is rendering related or caused by the export.
Hmm.. can't find it in the release notes, but it was mentioned from the beginning as a known issue. http://sourceforge.net/tracker/index.php?func=detail&aid=1472677&gro...
Svg and Pdf doesn't use the same colour space. You don't see it for all colours, but often enough to be annoying. I was about to add a simple approximation transform, but Inkscape is moving towards full colour management and ICC profiles. File an RFE if you wish
One important thing to add: the small "cell contents" particles are created as Clones, using varying transparency. This variation in transparency is completely absent in the PDF. However, unlinking the clones gives the same result in the exported PDF.
Try ungrouping all objects.
